Government deficit hits £100bn in the first half of the financial year

Revisions and corrections help reduce the budget overrun to £7bn for the six months to September 2025, but the outlook remains bleak.

The UK government deficit hit £100bn in the six months to September 2025, according to the latest Office for National Statistics’ (ONS) monthly public sector finances release for September 2025, published on 21 October 2025. 

The report also revealed a provisional shortfall between receipts and public spending of £20bn last month. The deficit for the month was £1bn higher than the previous year, in line with the budget. The cumulative deficit was £12bn higher than the first half of 2024/25, and £7bn more than budgeted.

Month of September 2025

Provisional receipts and total public spending for September – £95bn and £115bn respectively – were each 8% more than the previous year.

Current spending included depreciation of £108bn, comparable to the £108bn monthly average in the first five months of the financial year. Net investment was £7bn, higher than the £4bn monthly average investment between April and August 2025.

Excluding net investment, the current budget deficit for the month was £13bn – £2bn more than in the same month last year, £1bn more than budgeted. This was offset by a £1bn underspend on net investment.

Six months to September 2025

The provisional deficit for the six months to September 2025 was £12bn (14%) more than in the same six months last year. This was £7bn higher than budget, which can be analysed as a £13bn budget overrun on the current budget deficit (current receipts less current spending), less a £6bn underspend on net investment.

Table 1 highlights the changes in year-to-date receipts, up 7% overall on last year’s equivalents. These increases were mostly driven by factors such as inflation and fiscal drag from frozen tax allowances. The 20% increase in national insurance revenues reflects the increase in employers’ national insurance.

The 9% increase in current spending over the year has been driven by public sector pay rises, higher supplier costs, and the uprating of welfare benefits.

Net investment of £28bn in the first six months of 2025/26 was £1bn, or 4% higher than the same period last year. Capital expenditure of £46bn was up by £2bn and capital transfers (capital grants, research and development funding, and student loan write-offs) of £18bn were up by £1bn, offset by depreciation of £36bn, up by £2bn.

Budget for the rest of the financial year

The deficit is budgeted to be £118bn for the full year ending 31 March 2026, comprising £93bn in the first half of the year to September 2025 and £25bn in the second half of the year.

Borrowing and debt

Table 2 summarises government borrowing in the first six months of the financial year, taking public sector net debt to a provisional £2,916bn on 30 September 2025. This comprised £100bn in public sector net borrowing (PSNB) to fund the deficit and a further £6bn to fund government lending and working capital requirements.

The table also illustrates how the debt-to-GDP ratio increased by 1.6 percentage points, from a revised 93.7% of GDP at the start of the financial year to 95.3% on 30 September 2025, with incremental borrowing of £106bn, equivalent to 3.5% of GDP. It was partly offset by 1.9 percentage points due to inflation and economic growth adding to GDP.

Public sector net debt on 30 September 2025 of £2,916bn comprised gross debt of £3,368bn less cash and other liquid financial assets of £452bn. 

Public sector net financial liabilities were £2,565bn, comprising the net debt plus other financial liabilities of £715bn, less illiquid financial assets of £1,066bn. Public sector negative net worth was £908bn – net financial liabilities of £2,565bn less non-financial assets of £1,657bn.

Revisions

Caution is needed with ONS figures, which are repeatedly revised as estimates are refined, and gaps in the underlying data are filled. This includes local government, where numbers are updated in arrears and are based on budget or high-level estimates in the absence of monthly data collection.

This month, the ONS revised down the previously reported deficit for the five months to August 2025 by £4bn, including a £2bn error correction for understated VAT receipts. The ONS also increased the reported deficit for the previous financial year (2024/25) by £4bn to £150bn to incorporate estimates of local government actual expenditure.

More significantly, the ONS revised its methodology for calculating economic activity, resulting in an increase in GDP of 1%. Doing so causes historical percentages for deficit and debt as a proportion of GDP to be revised downwards. This includes a 1.1 percentage reduction in public sector net debt/GDP at the start of the financial year on 1 April 2025, from the previously reported 94.8% to the 93.7% shown in Table 2.  

Martin Wheatcroft, external advisor on public finances to ICAEW, said that public finances were broadly as expected, with the £20bn deficit for the month in line with budget.

“Borrowing to fund the deficit was a fraction under £100bn in the six months to September, the second-highest half-year deficit on record after the pandemic year. This was despite a narrowing of the year-to-date budget overrun to £7bn, as a consequence of error corrections and other revisions to previous months. In addition, statistical revisions to the size of the economy resulted in around a percentage point fall in the ratio of public sector net debt to GDP.”

Tepid economic growth and high debt interest costs will continue to weigh on prospects for the rest of the financial year, he added. “The revisions do very little to alter the bleak outlook for the public finances that is driving the need for a significant fiscal correction in the Autumn Budget 2025.”

Public finances turn ugly just as Chancellor needs good news

Weaker receipts than expected combined with prior month corrections resulted in a £12bn year-to-date budget overrun in the August monthly public finances.

The monthly public sector finances release for August 2025 published by the Office for National Statistics (ONS) on 19 September reported a provisional shortfall between receipts and total public spending of £18bn in August 2025 and £84bn for the five months then ended. These were £6bn and £12bn over budget respectively and £4bn and £16bn higher than in the same periods in 2024.

Martin Wheatcroft, external adviser on public finances to ICAEW, says: “This month’s public finance numbers took a turn for the worse as not only did weaker than expected receipts drive a £6bn budget overrun in August, but revisions to prior months added a further £6bn to the deficit to turn a broadly neutral position a month ago into a £12bn year-to-date budget overrun for the first five months of the 2025/26 financial year.

“These numbers are far from helpful to a Chancellor in desperate need of some good financial news, adding to the prospect of even higher tax rises in the Autumn Budget 2025 than previously feared.”

Month of August 2025

Receipts of £93bn in August 2025 were £5bn or 5% higher than the same month last year, while total public spending was £111bn, £8bn or 8% more than in August 2024. The latter can be analysed between current spending including depreciation of £107bn, slightly below the £108bn monthly average in the first four months of the financial year, and net investment of £4bn, in line with the monthly average incurred between April and July 2025.

Excluding net investment, the current budget deficit for the month of £14bn represented a £4bn deterioration over the current budget deficit of £10bn in the same month last year, highlighting how receipts have failed to keep pace with increases in current spending.

The overall £18bn fiscal deficit for the month was £6bn over budget and £4bn more than in August 2024.

Five months to August 2025

Table 1 highlights how year-to-date receipts of £477bn were up 6% on last year’s equivalents. This included income tax receipts, up 8% from a combination of inflation and fiscal drag from frozen tax allowances, and national insurance receipts, up 18% as a consequence of the increase in employer national insurance from April 2025. VAT receipts were flat year-on-year, in effect a 3% to 4% fall after taking account of consumer price inflation, highlighting the weak economic conditions facing the UK.

Meanwhile, the 8% increase over last year in current spending including depreciation to £539bn in the first five months to August 2025 has principally been driven by public sector pay rises, higher supplier costs, and the uprating of welfare benefits.

This included a £7bn or 12% increase in debt interest to £64bn, which comprised a £6bn increase in indexation on inflation-linked debt as inflation resurged and a £1bn increase in interest on variable and fixed-interest debt. The latter reflects a higher level of debt compared with a year ago being partially offset by a lower Bank of England base rate.

The resulting current budget deficit of £62bn to August 2025 was 29% higher than the £48bn for the same five months last year, a major concern given that the government’s plan was to reduce the cumulative current budget deficit to £47bn at this point.

Net investment of £22bn in the first five months of 2025/26 was £2bn or 10% higher than the same period last year with capital expenditure of £39bn up by £3bn and capital transfers (capital grants, research and development funding, and student loan write-offs) of £13bn up by £1bn, offset by depreciation of £30bn up by £2bn.

The overall provisional deficit for the five months to August 2025 of £84bn is £16bn or 24% more than in the same five months last year and £12bn higher than budget. The latter can be analysed as a £15bn budget overrun on current receipts less current spending for the year-to-date, less a £3bn saving on net investment.

Borrowing and debt

Table 2 summarises how the government borrowed £99bn in the first five months of the financial year to take public sector net debt to a provisional £2,909bn on 31 August 2025. This comprised £84bn in public sector net borrowing (PSNB) to fund the deficit and a further £15bn to fund government lending and working capital requirements.

The table also illustrates how the debt to GDP ratio increased by 1.6 percentage points from 94.8% of GDP at the start of the financial year to 96.4% on 31 August 2025, with incremental borrowing of £99bn, equivalent to 3.3% of GDP, being partly offset by 1.7 percentage points from the ‘inflating away’ effect of inflation and economic growth adding to GDP, the denominator in the net debt to GDP ratio.

Public sector net financial liabilities were £2,550bn, comprising net debt of £2,909bn plus other financial liabilities of £715bn less illiquid financial assets of £1,074bn. 

Public sector negative net worth was £893bn, being net financial liabilities of £2,550bn less non-financial assets of £1,657bn.

Revisions

Caution is needed with respect to the numbers published by the ONS, which are repeatedly revised as estimates are refined and gaps in the underlying data are filled. This includes local government, where the numbers are only updated in arrears and are based on budget or high-level estimates in the absence of monthly data collection.

This month was no different, with the ONS revising the previously reported deficit for the four months to July 2025 up by £6bn, as well as updating prior year numbers for the annual results of the Bank of England and several other public bodies as well as other typical annual updates such as revised student loan calculations. 

More significantly, the ONS revised reported deficits back to 1998 for methodology and classification changes and back to 2011 for local government outturn numbers that had not previously been incorporated. The reported deficits for 2020/21 and 2021/22 were decreased by £3bn and £2bn to £311bn and £120bn respectively, 2022/23 remained unchanged at £127bn, 2023/24 was increased by £2bn to £134bn, and 2024/25 was reduced by £2bn to £146bn.

12 Sep 2025. Chart by Martin Wheatcroft FCA. Sources: ONS, 'PAYE real time information, non-seasonally adjusted'; HMRC, 'Monthly tax receipts'.

According to the Office for National Statistics (ONS) and His Majesty’s Revenue and Customs (HMRC), UK employers paid a total of £111bn in gross salaries and employer national insurance in June 2025, an increase of £5.1bn or 4.8% over the same month a year ago.

My chart this week starts with the payroll in June 2024 of £105,823, comprising gross salaries paid by employers of £96,975m and employer national insurance of £8,848m, although it excludes employer pension contributions.

This monthly cost was reduced by £520m from a reduction in the national workforce, which saw the number of payrolled employees drop by 149,937 or 0.5% from 30,532,600 in June 2024 to 30,382,663 in June 2025. This arose from 7,296,859 leavers exceeding 7,146,922 joiners, most of which are people moving jobs. The reduction in the number of payrolled employees at a time of still-rising overall population numbers highlights the difficult economic situation currently facing the UK. The reduction comprised £476m in less pay and £44m in less employer national insurance (calculated at last year’s rates)

Salary increases since last year of approximately 3.6% added £3,985m or 3.8% to the cost of employment, with mean salaries increasing from £3,176 in the month of June 2024 to £3,291 in the month of June 2025. This comprised an increase of £3,501m or 3.6% in gross salaries and an estimated increase in employer national insurance of £484m or 5.5% (based on last year’s rates).

The median monthly salary increased from £2,389 in June 2024 to £2,530 in June 2025, which is a 5.9% increase compared with a year previously. This was less than monthly pay at the 25th percentile, which increased by 7.8% from £1,408 to £1,518, which was partly driven by a 6.7% increase in the minimum wage implemented in April 2025 (16.3% for those aged 18 to 20 and 18% for those aged under 18) that help lift the salaries of lower paid workers.

Pay at the 75th percentile increased by 4.7% (from £3,632 to £3,803) compared with a year previously, while pay at the 95th and 99th percentiles increased by 3.1% (from £7,461 to £7,692) and 2.6% (from £15,181 to £15,583) respectively. These lower rates of increase for higher paid workers primarily relate to base pay and so do not tell the full story as bonuses and other variable compensation for 2025 will in most cases not show up in pay packets until early next year.

A further £1,666m or 1.5% was added to the total cost of employment as a consequence of changes in employer national insurance effective from April 2025. These took the rate payable by employers from 13.8% of salaries over £792 a month to 15.0% of salaries above £417 per month, adding an extra 17.9% to the amount paid in employer national insurance after taking account of changes in the number of payrolled employees and salary increases since last year. Just under half of the increase (£808m) resulted from the change in the main rate of employer national insurance going up from 13.8% to 15.0% on salaries above £792 a month, with the balance (£858m) coming from lowering the threshold at which the 15.0% applies to £417 per month.

The overall effect was a net increase of £5,131m or 4.8% in total pay and employer national insurance to £110,954m in June 2025, comprising a net increase of £3,025m or 3.1% in total gross salaries to £100,000m and a net increase of £2,106m or 23.8% in employer national insurance to £10,954m.

The chart does not reflect the full cost of employment as it does not include employer pension contributions, non-payrolled benefits, and employment-related costs such as facilities, equipment, training and travel amongst others. However, it still gives a useful illustration of how payroll costs have changed significantly over the course of one year.

ICAEW’s growth campaign identifies how it is too difficult, expensive and uncertain to do business in the UK and calls for the government to do what it can to streamline regulations, reduce unnecessary costs, and provide businesses with the confidence they need to invest.

Little comfort for Chancellor as public finances stay in line

Borrowing to fund the deficit in the first four months of the financial year of £60bn was in line with expectations.

The monthly public sector finances release for July 2025 published by the Office for National Statistics (ONS) on 21 August reported a provisional shortfall between receipts and total public spending of £60bn for the four months ended 31 July 2025. This is in line with budget and £7bn more than in the same period last year.

Martin Wheatcroft, External Adviser on Public Finances to ICAEW, says: “This month’s ‘not bad’ result may provide a small amount of relief to a Chancellor under significant pressure.

“The monthly deficit for July was slightly better than expected, while the cumulative result for the first third of the financial year was almost exactly in line with the Office for Budget Responsibility’s prediction at the time of the Spring Statement 2025.

“Unfortunately, this does not change the dismal outlook for the public finances and the rising costs of public services, welfare provision and debt interest that means the Chancellor is again having to work out how she can ask Parliament to authorise higher levels of taxation.”

Month of July 2025

Receipts of £108.8bn in July 2025 were £9.2bn or 9% higher than in July 2024 and also higher than the £92.6bn average for the first three months of the financial year, principally as a result of a boost from income tax self-assessment collections in the month.

Meanwhile, current spending including depreciation of £105.5bn in July was £6.0bn or 6% more than in the same month a year previously. This was slightly lower than the £108.0bn monthly average incurred during April to June 2025.

The result was a current budget surplus for the month of £3.3bn, a £3.2bn improvement over the current budget surplus of £0.1bn in the same month last year.

Net investment of £4.4bn in July 2025 was £0.9bn more than the £3.5bn incurred in July 2024 and slightly higher than the £4.2bn average incurred during the three months to June 2025.

The provisional fiscal deficit for July 2025 was therefore £1.1bn, £1.0bn less than the £2.1bn budget for the month and a £2.3bn improvement over the £3.4bn deficit in July 2024.

Four months to July 2025

Table 1 highlights how year-to-date receipts of £387bn were up 7% on last year’s equivalents, with income tax receipts up 8% from a combination of inflation and fiscal drag from frozen tax allowances, and national insurance receipts up 19% as a consequence of the increase in employer national insurance that was implemented in April 2025.

Meanwhile, the 8% increase over last year in current spending including depreciation to £430bn in the first four months to July 2025 was primarily as a consequence of public sector pay rises, higher supplier costs, and the uprating of welfare benefits.

This included a £6bn or 13% increase in debt interest to £53bn, which comprised a £5bn increase in indexation on inflation-linked debt as inflation resurged and a £1bn increase in interest on variable and fixed-interest debt. The latter was primarily the result of a higher level of debt compared with a year ago partially offset by a lower Bank of England base rate.

The resulting current budget deficit of £43bn to July 2025 was 16% higher than for the same four months last year.

Net investment of £17bn in the first four months of 2025/26 was £1bn or 6% higher than the same period last year. Capital expenditure of £30bn was up by £1bn and capital transfers (capital grants, research and development funding, and student loan write-offs) of £11bn were up by £2bn, less depreciation of £24bn that was up by £2bn compared with the same four month period a year prior.

The consequence is a provisional deficit for the first third of the 2025/26 financial year of £60bn, which is £7bn or 13% more than in the same four month period last year. Despite being almost exactly in line with budget (only £0.1bn higher) this is the third-highest April-to-July deficit since monthly records began in 1993 (after 2020/21 and 2021/22 during the pandemic).

Borrowing and debt

Table 2 summarises how the government borrowed £81bn in the first third of the financial year to take public sector net debt to a provisional £2,891bn on 31 July 2025. This comprised £60bn in public sector net borrowing (PSNB) to fund the deficit and £21bn to fund government lending activities and working capital movements.

The table also illustrates how the debt to GDP ratio increased from 94.8% of GDP at the start of the financial year to 96.1% on 31 July 2025, with the incremental borrowing partly offset by the ‘inflating away’ effect of inflation and economic growth adding to GDP, the denominator in the net debt to GDP ratio.

Public sector net financial liabilities were £2,525bn, comprising net debt of £2,891bn plus other financial liabilities of £707bn less illiquid financial assets of £1,073bn. Public sector negative net worth was £899bn, being net financial liabilities of £2,525bn less non-financial assets of £1,626bn.

The latest release saw the ONS revise the previously reported deficit for the three months to June 2025 up by £1bn. The ONS also revised up its estimate of GDP in the first quarter of the financial year, resulting in a 0.4 reduction in the opening debt to GDP ratio on 1 April 2025 from 95.2% to 94.8% and the debt to GDP ratio for 30 June 2025 from 96.2% to 95.8%.

My chart this week looks at the impact on the US federal government deficit of the major tax and spending changes passed by Congress and signed into law by President Trump on 4 July 2025. 

The Congressional Budget Office (CBO) published on 21 July 2025 its assessment of Public Law 119-21 (the 21st law passed by Congress in its 119th session), also known as the One Big Beautiful Bill Act 2025 (OBBBA).

OBBBA was passed by Congress and signed into law by President Trump on 4 July 2025 and contains sweeping changes to the US federal tax system as well as a significant shift in spending priorities.

The chart this week attempts to illustrate the impact of OBBBA on the federal deficit by looking at how it changes the average annual projected deficit over the next 10 years from FY2025 (the current fiscal year ending on 30 September 2025) to FY2034, compared with the CBO’s baseline projection.

The baseline projection, published by the CBO in January 2025, was for the federal government deficit to increase from $1,865bn in FY2025 to $2,597bn in FY2034, an average deficit over the 10 years of $2,109bn or 5.8% of GDP.

According to the CBO, OBBBA is expected to increase the federal deficit each year by $339bn on average over the period to FY2034, with a net cut in federal spending of $110bn on average offsetting a net cut in revenues of $449bn. The CBO’s assessment does not take account of the additional cost of financing these higher deficits, which ICAEW calculates would add a further $68bn a year on average to the interest bill. 

The consequence is a net increase in the annual federal deficit of $407bn on average over 10 years, taking it to an average of $2,516bn or 7.0% of GDP.

Net spending cuts of $110bn comprise spending increases of $66bn a year on average, net of spending reductions of $164bn a year and incremental ancillary income that is deducted from spending of $12bn. Extra spending includes an extension of child tax benefits ($19bn a year on average) and more money for homeland security and immigration enforcement ($18bn), the military and coastguard ($17bn), farm subsidies ($5bn), air traffic control ($1bn), the mission to Mars ($1bn) and other items ($5bn). 

Spending reductions include cuts in Medicaid and Medicare programmes ($106bn on average each year), education and student loan relief ($30bn), other welfare and health programmes ($19bn), clean energy subsidies ($8bn) and other cuts ($1bn), while ancillary income comprises $9bn on average from spectrum auctions, $2bn from oil and gas leases, and $1bn extra from higher visa fees.

Net tax cuts comprise $511bn a year in tax cuts less $62bn a year in tax increases.

Tax cuts include making previous temporary tax cuts permanent ($379bn), business tax reforms ($97bn), personal tax reforms ($26bn), energy related tax credits ($4bn), Medicaid and Medicare related tax deductions ($3bn), and other ($2bn). Tax increases include the termination of tax reliefs for clean energy ($47bn a year), addressing tax loopholes ($6bn), additional immigration fees included in revenue ($4bn), taxing low-value international shipments ($4bn) and other ($1bn).

The CBO doesn’t directly conclude what this will mean for the US national debt (debt held by the public), which was expected in January’s baseline projection to increase from $28.2tn or 98% of GDP at the start of the current financial year to $49.5tn or 117% of GDP on 30 September 2034. Adding $4.1tn over 10 years to that amount suggests this would increase to $53.6bn or 127% of GDP.

These numbers don’t take account of the anticipated economic boost of lower taxes that should partially offset some of the tax impacts set out in the CBO’s analysis, as well as increasing the denominator in the deficit to GDP ratio. However, they also don’t take account of other factors such as US trade policy – including the additional tax receipts from tariffs and the potential effect that those higher taxes will have on the US economy – or many other policies of the US administration. We will need to wait for the CBO’s next full economic and fiscal projections later in the year to understand more about what that might mean.

Either way, the OBBBA will go down as one of the most consequential legislative acts of the US Congress in recent years.

First quarter fiscal deficit in line as Chancellor ponders tax rises

Despite borrowing to fund the deficit in the first three months of the financial year of £58bn being in line with expectations, it was still the third-highest first quarter result on record.

The monthly public sector finances release for June 2025 published by the Office for National Statistics (ONS) on 22 July reported a provisional deficit of £21bn for the month of June and £58bn for the three months then ended. This is £4bn more and in line with budget respectively, and £7bn and £8bn more in each case than the first fiscal quarter a year ago.

Alison Ring OBE FCA CPFA, ICAEW Director of Public Sector and Taxation, says: “Even if borrowing to fund the deficit in the month of June was only a little higher than expected and was in line with expectations in the first three months of the financial year, the first quarter was still the third highest since monthly records began. This trajectory will not have lightened the Chancellor’s mood as she decides which taxes to put up in the Autumn Budget later this year. 

“The government has two big problems with the public finances: the short-term outlook – which is bad – and their long-term prospects – which are worse. Public spending continues to outpace tax receipts by a significant margin, while the OBR has reiterated its conclusion that the public finances are unsustainable over the next 25 to 50 years if this and future governments continue on the current path. 

“Unfortunately, the major challenges facing the public finances over the next quarter of a century and beyond means that this will not be the last time a chancellor of the exchequer needs to come back asking for more. Now is the time to stop kicking the can down the road and develop a comprehensive long-term fiscal strategy to put the public finances onto a sustainable path.”

Month of June 2025

The fiscal deficit for June 2025 was £21bn, £4bn more than budgeted and £7bn more than a year previously. According to the ONS, this was the second-highest June deficit since monthly records began in 1993, with only June 2020 during the pandemic being higher.

First quarter to June 2025

The deficit for the first three months of the 2025/26 financial year was £58bn, £8bn more than a year previously. Despite being in line with budget, this is the third-highest first quarter deficit since monthly records began (after the first quarter deficits in 2020/21 and 2021/22). 

Table 1 highlights how total receipts and total current spending in the three months to June 2025 of £278bn and £323bn were up 7% and 8% respectively, compared with the same period last year.

Receipts were boosted by the employer national insurance increase from April 2025 onwards in addition to the effect of fiscal drag on income tax caused by the continued freeze in personal tax allowances. Meanwhile, the increase in current spending over the past year was primarily as a consequence of public sector pay rises, higher supplier costs and rises in welfare benefits.

The increase in debt interest of £5bn to £42bn consisted of a £6bn increase in indexation on inflation-linked debt as inflation returned less a £1bn reduction in interest on variable and fixed-interest debt. The latter was primarily the effect of a lower Bank of England base rate offsetting a higher level of debt compared with a year ago.

Net investment of £13bn in the first quarter of 2025/26 was £1bn or 8% higher than the same period last year. Capital expenditure of £22bn was up by £1bn and capital transfers (capital grants, research and development funding, and student loan write-offs) of £9bn were up by £1bn, less depreciation of £18bn up by £1bn.

Borrowing and debt

Table 2 summarises how the government borrowed £64bn in the first quarter to take public sector net debt to £2,874bn on 30 June 2025. The movements comprised £58bn in public sector net borrowing (PSNB) to fund the deficit and £6bn to fund government lending activities and working capital movements.

The table also illustrates how the debt to GDP ratio increased from 95.2% of GDP at the start of the financial year to 96.3% on 30 June 2025, with the incremental borrowing partly offset by the ‘inflating away’ effect of inflation and economic growth adding to GDP, the denominator in the net debt to GDP ratio.

Public sector net debt on 30 June 2025 of £2,874bn comprised gross debt of £3,286bn less cash and other liquid financial assets of £412bn. 

Public sector net financial liabilities were £2,504bn, comprising net debt of £2,874bn plus other financial liabilities of £706bn less illiquid financial assets of £1,076bn. Public sector negative net worth was £878bn, being net financial liabilities of £2,504bn less non-financial assets of £1,626bn.

Revisions

Caution is needed with respect to the numbers published by the ONS, which are repeatedly revised as estimates are refined and gaps in the underlying data are filled. This includes local government where the numbers are only updated in arrears and are based on budget or high-level estimates in the absence of monthly data collection.

The latest release saw the ONS revise the previously reported deficit for the two months to May 2025 down by £1bn and revise public sector net debt on 31 May 2025 up by £7bn.

ICAEW chart of the week: climate change and the public finances

My chart for ICAEW this week looks at how climate change is now expected to make the OBR’s dire predictions for the public finances even worse.

A line chart on climate change and the public finances, with three curved lines for public sector net as a share of GDP over fifty years. with labels from March 2034 onwards. 

Bottom line: Baseline public sector net debt/GDP. Falls from just under 100% of GDP to 90% of GDP in March 2034 and then rises to 100%, 130%, 188% and 274% of GDP in March 2044, 2054, 2064 and 2074 respectively. 

Middle line: Baseline + climate change (below 3°C scenario). Rises from 94% of GDP in March 2034 (label not shown) to 114%, 157%, 235% and 348% of GDP in March 2044, 2054, 2064 and 2074 respectively. 

Top line: Baseline + climate change + economic shocks. Rises from 104% in March 2034 to 134%, 187%, 275% and then 398% in March 2074. 

18 Jul 2025. Chart by Martin Wheatcroft FCA. Design by Sunday. Sources: OBR, 'Fiscal risks and sustainability', Sep 2024 and Jul 2025 reports.

ICAEW’s chart of the week is on climate change this week, illustrating how it could add a further 74 percentage points to the Office for Budget Responsibility (OBR)’s already disheartening baseline projection for public sector net debt of 274% of GDP to reach 348% of GDP, or potentially 398% if economic shocks are included.

The baseline projection, published by the OBR in September 2024, showed public sector net debt as a proportion of the size of the economy falling from just under 100% of GDP to 90% of GDP in March 2034 and then rising to 100%, 130%, 188% and 274% of GDP in March 2044, 2054, 2064 and 2074 respectively. 

One of the main drivers of the baseline projection is the expected rise in spending on pensions, health and social care as more people live longer, sometimes less healthy lives, combined with a falling fertility rate that means there will be proportionately fewer working age adults to pay the taxes needed to fund that rise.

Incorporating the OBR’s new central projection for climate change, public sector net debt would be 94% of GDP in March 2034 (not shown in the chart because of a lack of space between lines) and then 114%, 157%, 235% and 348% of GDP in March 2044, 2054, 2064 and 2074 respectively. Adding potential economic shocks on top would increase the projection for public sector net debt/GDP to 104% in March 2034 rising to 134%, 187%, 275% and then 398% in March 2074.

The September 2024 baseline projection included the loss of fuel duty receipts from the phasing out of petrol and diesel vehicles between now and 2050, but the OBR in its recent July 2025 fiscal and sustainability report has looked in more detail at both the incremental costs of transitioning to net zero and the damage that is likely to result from a much warmer and wetter climate in several different scenarios.

OBR’s central ‘below 3°C’ scenario is based on global average temperatures rising by 2.9°C above pre-industrial levels by 2100, of which weather and other damage associated with a much warmer and wetter climate is projected to add 17 percentage points to accumulated debt over the next half century from direct and indirect costs and revenue losses. Climate damage is also expected to result in slower economic growth that would add 27 percentage points over 50 years by reducing the denominator in the debt to GDP ratio. The government’s share of transition costs (including lower tax receipts from higher private sector spending) is projected to add 7 percentage points, while there is a 22 percentage point impact from the incremental debt interest that would be incurred on a higher level of debt.

This is before taking account of recessions and other potential economic shocks, which based on historical patterns are expected to add 10% of GDP to public sector net debt every decade or so.

The chart does not reflect other risks identified by the OBR in its latest report, where it reports that the exposures to the public finances have increased since its assessment last year. One risk they did look at in some detail is the prospect of higher interest rates on government borrowing on the basis that demand for gilts reduces as the Bank of England winds down its holdings of gilts (quantitative tightening) and defined benefit pension schemes gradually sell their holdings of gilts to fund pension payments. This risk might be mitigated by selling shorter-dated gilts, although shorter maturities would make the public finances less resilient by increasing the amount of debt needing to be refinanced each year.

The OBR’s dismal assessment of the prospects for the public finances highlights just how difficult a financial position the UK finds itself in, with a lot to do (and some luck needed) if it is to be restored to a sustainable path. At the same time, the costs of climate change are now becoming that much more apparent as extreme weather events and other climate-related costs start to show up in public finance and insurance data.

ICAEW chart of the week: Spending up

My chart for ICAEW this week looks at what the Spending Review 2025 does to total day-to-day spending and capital budgets over the next three years.

A step chart showing the Spending Review 2025 change in total departmental budgets over three years. 

2025/26: Day-to-day spending £517bn + Capital investment £131bn = total £648bn. 

Inflation: +£38bn (+1.9% a year). 

Day-to-day spending: +£21bn (+1.3% a year). 

Capital investment: +£10bn (+2.4% a year). 

2028/29: Day-to-day spending £568bn + Capital investment £149bn = total £717bn.

Last week’s chart of the week looked at the winners and losers between departments in the Spending Review 2025. This week’s chart looks at the overall picture and the government’s different approaches between operating and capital expenditure.

As my chart this week illustrates, total departmental budgets for the current financial year ending on 31 March 2026 (2025/26) of £648bn are expected to rise to £717bn by 2028/29. This comprises departmental ‘day-to-day’ operating budgets of £517bn in 2025/26 that rise to £568bn in 2028/29 and departmental capital budgets going from £131bn to £149bn over the same period.

Inflation of 1.9% a year on average is expected to add £38bn a year to total departmental spending by the end of the three-year period, with a real-term increase in operating budgets of £21bn by 2028/29 or 1.3% a year on average, and a real-term increase in capital budgets of £10bn or 2.4% a year on average. 

In practice, the increase in day-to-day spending is not much of an increase at all given that ‘government inflation’ is often higher than the GDP inflator all-economy measure of inflation used in HM Treasury’s calculations. Pay awards and supplier price rises are likely to absorb a significant proportion of this additional money, with departments needing to find significant efficiency savings and productivity improvements if they are to avoid cuts to public services, let alone improve them. And, as our chart last week highlighted, several departments are in effect having their operating budgets cut over the spending review period. 

Unlike operating budgets, where total planned departmental spending increases each year broadly in line with inflation and the 1.3% average real-term increase, the average annual real-term increase of 2.4% a year in capital budgets over three years comprises a 6.9% real-term increase in 2026/27, a real-term cut of 0.2% in 2027/28, and a real-term increase of 0.7% in 2028/29. (There is also no increase after inflation in the fourth year to 2029/30, which would reduce the average annual increase over four years to 1.8%.)

This follows an 11.6% real-term increase in capital budgets in 2025/26 that was enabled by the Chancellor’s change to the fiscal rules in the Autumn Budget 2024. This gave the government more flexibility to borrow for capital investment, and the Chancellor chose to front load that investment, no doubt in the hope of accelerating the economic benefits of that investment and of improving public services more quickly than might be possible if spreading the increase more evenly over the spending review period.

Whether the government will be able to actually deliver its planned capital programmes as quickly as it might hope remains to be seen, as will whether that investment in turn actually results in stronger economic growth and better public services. Let’s hope it does, as we could definitely do with a boost.

13 Jun 2025. Chart by Martin Wheatcroft. Design by Sunday. Source: HM Treasury, 'Spending Review 2025'.

The Spending Review 2025 establishes base operating budgets for government departments for the three financial years from 1 April 2026 (2026/27, 2027/28 and 2028/29) and base capital budgets for four financial years (extending to 2029/30).

Departmental budgets for the current financial year ending on 31 March 2026 (2025/26), total £648bn and are expected to rise to £678bn in 2026/27, £697bn in 2027/28, and £717bn in 2028/29, an increase of 10.6% over the three years or 3.4% a year. This is equivalent to an average increase of 1.5% a year in real terms after adjusting for inflation of 1.9% a year on average over the spending review period.

The totals can be analysed between operating or ‘day-to-day’ budgets of £517bn, £536bn, £552bn and £568bn in 2025/26, 2026/27, 2027/28 and 2028/29 respectively and capital budgets of £131bn, £143bn, £145bn and £149bn. These are real terms increases of 1.2% and 2.4% a year on average over three years. 

The capital budget in 2029/30 is £152bn, a cut in real terms that reduces the average annual increase in capital budgets over four years to 1.8% a year on average.

My chart this week highlights how the 1.5% average annual real increase over three years in total budgets (operating and capital) has been allocated across departments, starting with the Ministry of Defence, which leads the pack with an average increase in its budget of 3.8% a year, followed closely by the security services, with an average annual increase of 3.7%. This reflects the elevation of national defence and security to the top of the government’s priorities since the general election last year, even though this increase will only move defence and security spending from 2.3% of GDP currently to 2.6% of GDP by 2027, a long way off the proposed 3.5% of GDP new minimum to be discussed at the NATO summit.

Economic growth and the NHS are the next highest priorities for the government and so it is perhaps unsurprising that the Department of Business & Trade does well with an annual average increase of 3.0%, closely followed by the Department of Health & Social Care, which receives 2.7%. The latter is the biggest increase in cash terms, at £31bn in total or about £12bn more in 2028/29 after adjusting for inflation.

Local government finances are in a parlous state and so the government has pencilled in a 2.6% average annual increase in core budgets for local authorities in England over the next three years. However, it is only increasing central funding by 1.1% a year on average, implying the balance will need to be made by local taxation, principally council tax.

The Ministry of Justice has been awarded 2.0% a year on average as the government seeks to tackle significant backlogs in the courts, overcrowded prisons and significantly under-resourced probation services.

The Department of Science, Innovation and Technology has received a below average annual increase of 0.9% over the next three years, but this follows an almost 12% increase over the past two years as the government has sought to increase investment in research and development to boost economic growth.

Despite being a key priority for the government, the Department for Education has only received a 0.8% average annual increase, partly because of falling primary school rolls in line with a significant fall in the birth rate over the last decade.

The devolved administrations – Scotland (0.8%), Wales (0.7%) and Northern Ireland (0.5%) – are budgeted to receive an average of 0.7% a year over three years as a consequence of the Barnett formula that links UK national government spending in England to the block grants provided to each devolved administration, adjusted for relative changes in population among other factors.

The Cabinet Office is expected to receive just 0.4% on average reflecting the contribution that planned efficiency savings are expected to contribute to administrative budgets. This is also the reason for the 0.2% a year real-terms fall in the Department for Work and Pensions (DWP) budget as automation helps reduce the cost of administering the welfare system.

The budget of the Department for Transport is expected to fall by 0.5% a year overall, but this partly reflects a fall in spending on High Speed 2 as it comes closer to completion. If that is excluded, the department’s budget is expected to increase by 0.5% a year on average. The actual increase in spending should be even higher, as the budget is net of passenger revenues that are expected to grow at a faster rate over the next three years.

Extra money for housing was found within the spending review, but this wasn’t enough to stop the budget for the Department of Housing, Communities and Local Government from shrinking by an annual average of 0.6% a year as other activities are cut back, while the Department for Culture, Media & Sport (-1.4% a year on average) has also been asked to cut back its activities.

HMRC (-1.5% a year) and HM Treasury (-1.9% a year) see their budgets reduced significantly, with digitisation and efficiency savings expected to contribute significant sums.

The Department for Farming, Agriculture, and Rural Affairs (-2.3%) is also expected to see significant cuts over the next three years, as is the Foreign, Commonwealth and Development Office (-8.3%), although in the latter case that is principally driven by the decision to reduce overseas development assistance from 0.5% of GDP to 0.3% of GDP although some will come from back office savings.

Not shown in the chart are small and independent bodies and the government legal function, which are together expected to increase by 0.4% a year on average, although this comprise a -0.5% annual reduction in the former and a 5.3% average annual increase in the latter. The net changes after inflation are a fall of less than £0.1bn and an increase of just over £0.1bn respectively, which are rounding errors in the hundreds and hundreds of billions of pounds spent by government departments each year.

March 2025 marked the end of the first fiscal quarter of the 21st century, comprising the 25 financial years from 2000/01 to 2024/25. Our chart this week takes a look at how it compares with the previous four quarters in the 20th century.

Our chart starts with the first quarter of the 20th century that started on 1 April 1900 and ended on 31 March 1925 – the comparative period a century ago. Public sector net debt increased by £7bn (from just under £1bn to just under £8bn) and by 142 percentage points of GDP (from 33% of GDP to 175% of GDP) over the 25 years. 

As the chart illustrates, the increase in the net debt to GDP ratio reflected an increase in the numerator from borrowing of 184% of GDP, partially offset by 42% of GDP from the ‘inflating away’ effect of economic growth and inflation on the denominator. 

Almost all of the borrowing in the first quarter a century ago was incurred to finance the First World War, while the severe contraction in the UK economy after the war (partly because of the global ‘Spanish flu’ influenza pandemic) meant that the erosion of net debt as a share of GDP from economic growth and inflation was just 42% instead of the 84% it had been in the first 20 years of the century.

Around £15bn of the £18bn or 210% of GDP that was borrowed during the second quarter of the 20th century was during the Second World War years from 1940/41 to 1945/46. This was substantially offset by strong economic growth during the quarter (especially in the five years up to 1949/50 as the nation emerged from the war) that saw debt ‘inflated away’ by 182% of GDP. The consequence was an increase of just 28 percentage points in net debt as a share of GDP to 203% of GDP on 31 March 1950.

The third quarter of the 20th century saw the government borrow a further £26bn, resulting in net debt doubling to £52bn on 31 March 1975. However, net debt fell as a share of GDP by 155 percentage points to 48% of GDP, with borrowing of 48% of GDP being more than offset by a 203-percentage point reduction from economic growth and inflation increasing the denominator in the net debt/GDP ratio.

The last quarter of the 20th century saw a further reduction in the ratio of net debt to GDP of 16 percentage points, from higher borrowing of £301bn or 72% of GDP being offset by an 88% of GDP inflating away effect of economic growth and inflation. Net debt reached £353bn on 31 March 2000, equivalent to 32% of GDP.

The first quarter of the 21st century, based on provisional numbers for the year ended 31 March 2025, saw net debt/GDP increase by 64 percentage points, with £2,461bn or 130% of GDP borrowed over the past 25 years, taking net debt to £2,814bn and net debt/GDP to 96% of GDP after reflecting a 66% of GDP inflating away effect from economic growth and inflation.

One positive from these comparisons is that at least the latest quarter was not as bad as the comparative quarter a century ago. However, for a period of peacetime we still managed to borrow approaching ‘warlike’ sums to fund the costs of a financial crisis, a pandemic (although the comparative period had one of those too) and an energy crisis that all combined to increase public sector net debt massively. Meanwhile, lower levels of economic growth than in the second half of the 20th century mean that we have not inflated debt away as quickly as we might hope.

As we start the second quarter of the 21st century, the hope is that we can avoid wars, boost economic growth, control spending to keep borrowing under control and – at the same time – increase the speed at which debt is inflated away. Doing so will be essential if we are to move the public finances back onto a sustainable path.
