UK social protection spending — covering state pension, housing benefit, Universal Credit, disability benefits, child benefit, and tax credits — is projected at £328 billion in 2026/27 (HM Treasury). The state pension alone accounts for approximately £130 billion. Per UK household: approximately £11,600 per year. This is 24% of all government spending.
Total Welfare Spending in 2026/27
Social protection — the collective term for benefits, pensions, and income transfers — is the single largest category in the UK government's spending plans. At approximately £328 billion in 2026/27, it dwarfs every other department, exceeding health (£272 billion) by a substantial margin and representing nearly one in every four pounds of government spending.
This figure has grown in real terms in almost every year for the past two decades. In 2010/11, social protection spending was approximately £220 billion. The increase to £328 billion reflects primarily the rising cost of the state pension (driven by the triple lock, an ageing population, and rising longevity), the growth in working-age disability benefits, and the increasing cost of housing support.
Social protection spending is classified as Annually Managed Expenditure (AME) — meaning it cannot be directly controlled by government in the way departmental budgets can be. It rises and falls with the number of eligible claimants and the economic conditions that determine them. This "demand-driven" nature makes social protection spending particularly difficult to control fiscally, contributing to its growth as a share of total spending.
The OBR's long-term projections show social protection spending continuing to rise as a share of GDP over the next 50 years, driven primarily by the state pension (demographic ageing) and disability-related benefits (a structural increase in claims that predates the pandemic and has continued since).
The Breakdown: Where the £328bn Goes
The DWP administers the majority of benefit expenditure. The breakdown by major category in 2026/27 (OBR projections based on 2024/25 outturn and Autumn Budget 2024 plans):
| Benefit | £bn (2026/27) | % of social protection | Approximate claimants |
|---|---|---|---|
| State Pension | ~£130bn | 39.6% | ~12.7m pensioners |
| Housing Benefit / LHA element of UC | ~£30bn | 9.1% | ~4.5m households |
| Universal Credit (exc. housing) | ~£28bn | 8.5% | ~6.6m claimants |
| Disability Living Allowance / PIP | ~£26bn | 7.9% | ~3.4m |
| Attendance Allowance | ~£8bn | 2.4% | ~1.7m |
| Child Benefit | ~£14bn | 4.3% | ~7m families |
| Employment & Support Allowance (legacy) | ~£8bn | 2.4% | ~1.3m (declining) |
| Pension Credit | ~£6bn | 1.8% | ~1.4m |
| Tax Credits (legacy) | ~£5bn | 1.5% | ~0.4m (declining) |
| Other / admin / transitions | ~£73bn | 22.3% | Various |

State Pension: The Biggest Single Payment
The new State Pension was introduced in April 2016 and provides a flat-rate pension to those with 35 or more qualifying years of National Insurance contributions. In 2025/26, the full new State Pension is £11,502 per year (£221.20 per week). The old basic State Pension — paid to those who reached state pension age before April 2016 — is £169.50 per week (£8,814 per year) with potential additional state pension (SERPS/S2P) on top.
The state pension is protected by the triple lock — a commitment that it rises each year by the highest of CPI inflation, average earnings growth, or 2.5%. The triple lock has contributed significantly to the rising cost of the state pension: between 2010/11 and 2025/26, the full basic State Pension more than doubled in nominal terms from approximately £97 per week to £169 (old pension) and the new State Pension was set at a higher base.
Approximately 12.7 million people receive the state pension. This number is growing by approximately 200,000 per year as baby boomers age into state pension age. The OBR projects state pension spending will exceed £165 billion by 2030/31 even if the triple lock remains in its current form. Any reform — whether moving to a double lock (removing the 2.5% floor) or earnings-linking only — would save billions annually but faces significant political resistance.

Universal Credit: Who Claims and How Much
Universal Credit replaced six legacy benefits (Jobseeker's Allowance, Income Support, Employment and Support Allowance, Housing Benefit, Child Tax Credit, and Working Tax Credit) and was fully rolled out for working-age claimants by 2024. Approximately 6.6 million people claimed UC in early 2025, though this figure includes significant numbers of working people whose earnings are topped up by the benefit.
The structure of UC is a standard allowance (approximately £311 per month for a single person over 25 in 2025/26) plus elements for children, housing costs, limited capability for work, and care responsibilities. For every £1 of net earnings above the work allowance threshold, UC is reduced by 55p — a taper rate that has been criticised for creating high marginal effective tax rates on earnings for low-paid workers.
The disability elements of UC — the Limited Capability for Work and Work-Related Activity (LCWRA) element — have become a significant area of expenditure growth. The number of UC claimants in the LCWRA group has grown substantially since 2020, reflecting both post-pandemic health impacts and — in DWP's assessment — a structural increase in disability-related benefit claims. Reform of these elements is central to the DWP's fiscal sustainability work for 2025/26 and beyond.
Housing Benefit: The Rising Cost
Housing benefit — now largely administered through the housing cost element of Universal Credit — costs approximately £30 billion per year and covers rental costs for approximately 4.5 million lower-income households who cannot afford market rents from their own income. The cost has risen substantially, driven by private sector rent inflation exceeding Local Housing Allowance (LHA) rates for much of the 2010s.
LHA was frozen in cash terms between 2016 and 2024, meaning it covered a progressively smaller proportion of market rents as rents rose. It was unfrozen and reset to the 30th percentile of local market rents in April 2024 — a significant increase that added approximately £1.3 billion to the annual cost. The fundamental driver of housing benefit spending is the gap between market rents (particularly in London and the South East) and the incomes of people in low-paid work or on benefits.
How UK Welfare Compares Internationally
Comparing welfare systems across countries is complicated by differences in what is included, how the system is structured (insurance-based vs. tax-funded), and what conditions are attached. By the OECD's measure of public social expenditure as a percentage of GDP, the UK spends approximately 21–22% — broadly in line with the European average and ahead of the United States (approximately 18%).
Scandinavian countries (Denmark, Sweden, Finland) spend 25–30% of GDP on social protection, reflecting more comprehensive systems and higher replacement rates. Germany and France spend approximately 25–27%. The UK's level of spending is therefore moderate by European standards but high in absolute terms due to the scale of the economy.
One structural feature that inflates UK welfare spending relative to some comparators is the high cost of housing benefit. Other European social housing systems provide subsidised housing directly (Germany, Netherlands, Austria) rather than paying benefits to fund private sector rents — a model that is typically cheaper at scale. The UK's reliance on housing benefit rather than social housing supply has been identified by the IFS, Resolution Foundation, and OBR as a significant driver of welfare cost growth.
