What is the short version?

  • Three measures of defence spending: HM Treasury’s by function, the MOD’s own budget, and NATO’s core defence, which the commitments use. They are shown apart.
  • Defence is spent for the UK as a whole, so there is no nation or local breakdown.
  • The last Equipment Plan was unaffordable by £16.9bn; its replacement has no affordability table yet.

Defence, United Kingdom: spending in cash and in 2025-26 prices, £ billion

Real terms use HM Treasury’s GDP deflator, 2025-26 prices. Breaks in the series: 1988-89: Before 1988-89 the UK series is the OBR’s historical defence figure; from 1988-89 it is HM Treasury’s PESA. 2011-12: The MOD’s spending categories start in 2011-12; war pensions and the DE&S trading entity were classified differently before 2015-16.

Search the department's payments over £25,000

Every payment of £25,000 or more the department published for the latest year, as published. See every department's spending over £25,000 for what each covers.

Ministry of Defence published 31,171 payments worth £15.17bn to 1,424 suppliers and recipients from April 2025 to March 2026 (12 of 12 months published). Payments the MOD judges would harm national security are left out of its files; it publishes a note on these exemptions.

Gaps and problems in the data, as published (4)
  • The newest payment published is from 2026-03, 6 months before this was read.
  • 5 rows were dropped because the date or amount could not be read.
  • 41% of rows are under £25,000: the department lists individual lines of larger payments, or publishes some smaller ones. They are kept as published.
  • 1 payment is dated after the day this was read, which cannot be right; left out.

Can the plans be paid for?

The last Equipment Plan, for 2023 to 2033, put forecast costs at £305.5bn against a budget of £288.6bn: a gap of £16.9bn (6%). The National Audit Office found the plan unaffordable: forecast costs exceeded the budget by £16.9bn, the largest gap since it began reporting on the plan in 2012. (National Audit Office, The Equipment Plan 2023 to 2033, 4 December 2023.)

No Equipment Plan has been published since. The Defence Investment Plan (30 June 2026) replaced it and does not include a costs-against-budget table; the National Audit Office has a review of its affordability under way.

Major programmes

The Ministry of Defence had 44 projects in the Government Major Projects Portfolio at March 2026. 9 were rated red by the independent assessors, meaning successful delivery appeared unachievable without action; 10 amber, 1 green, and 24 had no published rating. Whole-life costs were published for 24, together £95.1bn; the other 20 were withheld, most as commercially sensitive.

Costs in 2024-25 prices, as the portfolio publishes them. From April 2026 the portfolio was cut to about 80 projects, so next year’s figures will not be comparable. Every major project, across government.

What people say about it

Should defence spending rise faster towards 3% of GDP or beyond?

Those who say defence spending should rise faster or further

  • Rather than kicking the can down the road, waiting for a fiscal event in a future year, will the Prime Minister urgently commit to charting a pathway to reaching 3% of GDP being spent on defence by 2030? Tan Dhesi MP (Labour), chair of the Defence Committee, House of Commons (3 September 2026) As quoted by UK Defence Journal (Prime Minister's Questions).
  • That's why we are setting out our plans to reach 3% on defence spending by the end of this Parliament through further cuts to welfare and restoring the two-child benefit cap. Kemi Badenoch MP, Conservative leader, Conservative Party (2 September 2026) As quoted by LBC.
  • Page one of the Review must include a firm commitment to boost defence spending to 3% of GDP as soon as possible. Sir Ed Davey MP, Liberal Democrat leader, Liberal Democrats (1 June 2025)

Those who stress affordability, or spending existing money better first

  • We are going to be in the situation, for the first time in a really long time, where we see both health and defence spending rising as a share of national income. Bee Boileau, economist, Institute for Fiscal Studies (26 September 2025) As quoted by The Telegraph (via Yahoo News). She also said the £36bn a year needed to reach 3.5% was "not a sum that can be found painlessly".
  • But in the midst of these issues, our report finds that the MoD is far behind the curve in preventing the loss of precious public funds which could be spent on keeping our nation safe. Sir Geoffrey Clifton-Brown MP (Conservative), chair of the Public Accounts Committee (29 May 2026) He also said the committee welcomes the aim to spend a rising share of GDP on defence; his concern is the delayed Defence Investment Plan and money lost to fraud and cancelled projects.
  • Security is not just based on arms expenditure and threats, but on real leadership that uses diplomacy and development too. Ellie Chowns MP, Green Party defence spokesperson (2 June 2025)

What these figures do and don't show

  • Three measures, not one. HM Treasury’s spending on defence (the long-run chart), the MOD’s departmental limits (the drill-down) and NATO’s core defence spending (the share of GDP) count different things and do not match.
  • Pensions are counted differently. HM Treasury puts armed forces and war pensions under social protection; NATO counts them in defence.
  • Plans are not spending. The Defence Investment Plan budget and the commitments are shown as plans, apart from outturn.
  • Headcount is not capability. Numbers serving say nothing on their own about readiness or equipment.
