Contract inflation adjustments: the invisible defunding of charities
Government contracts and grants are not routinely uprated for inflation, forcing UK charities to absorb real-terms cuts year on year. A slow, invisible defunding mechanism explained.
The debate in brief
When a charity signs a government contract or receives a multi-year grant, the value of that funding is fixed in nominal terms. If the contract is not uprated for inflation each year, the charity receives the same number of pounds but can buy less with them. Staff costs rise with the National Living Wage and pension auto-enrolment thresholds. Energy, rent, insurance, and materials all increase. The contract stays the same. The gap is a real-terms cut, and the charity absorbs it. Repeated across thousands of contracts and grant agreements over a decade and a half of constrained public spending, this mechanism has quietly removed billions from the sector's effective funding base without anyone having to announce a single cut.
Quick takeaways
| Question | Answer |
|---|---|
| Do government contracts include inflation uplifts? | Most do not, or include uplifts below actual cost increases. There is no standard requirement for inflation adjustment in public service contracts with charities. |
| How much has this cost the sector? | Precise figures are difficult to isolate, but with CPI inflation running at 7-11% in 2022-23 and charity income from government largely static in cash terms, the real-terms erosion runs into billions across the sector. |
| Is this a deliberate policy? | Not explicitly. It is a consequence of how contracts are written, how local authority budgets are set, and how commissioning culture treats fixed-price agreements as the norm. The effect, however, is indistinguishable from a funding cut. |
| Which charities are most affected? | Those most dependent on government contracts for their income, particularly in social care, homelessness, mental health, and domestic abuse services. Small and medium-sized charities have the least capacity to absorb the shortfall. |
| Can charities negotiate inflation clauses? | In principle, yes. In practice, competitive tendering and commissioner budget constraints make this extremely difficult, especially for smaller organisations. |
The arguments
The case for inflation adjustment
The argument is simple arithmetic. If a charity is contracted to deliver a service at a fixed price, and the costs of delivering that service rise each year, the charity is being asked to do more for less in real terms. This is not a matter of opinion. It is how inflation works.
Staff costs are the single largest expenditure for most service-delivering charities, typically accounting for 60-80% of total spending. The National Living Wage has increased every year since its introduction in 2016, rising from £7.20 to £12.21 by April 2025. Pension auto-enrolment contributions have increased. The employer National Insurance Contributions threshold was lowered from April 2025, adding further cost. None of these are discretionary expenses. They are legal obligations. A contract that does not adjust for them is a contract that assumes the charity will find the money from somewhere else.
Beyond staff costs, the inflationary environment of 2022-24 drove sharp increases in energy, food, insurance, and property costs. The Consumer Prices Index reached 11.1% in October 2022, the highest rate in over forty years. Charities delivering residential services, running buildings, or providing food saw their operating costs surge. Their contract income did not.
The Charity Finance Group has argued that inflation adjustment should be a standard clause in any multi-year contract or grant, not a concession to be negotiated. The Treasury Green Book recognises that grants should reflect full economic costs, and those costs are not static. A contract that is adequate in year one but ignores inflation in years two through five is, by definition, inadequate for the majority of its term.
The commissioner's constraints
The counterargument is not that inflation adjustment is wrong in principle. It is that commissioners cannot afford it. Local authority budgets have been under sustained pressure since 2010. The Local Government Association has estimated that councils in England face a funding gap of £4 billion by 2026-27. When a council's own budget is not keeping pace with inflation, it has no mechanism to pass inflation uplifts through to its contracted providers.
Central government departments face similar constraints. Multi-year spending settlements are set in cash terms, and departments must manage inflationary pressures within fixed envelopes. The practical effect is that inflation risk is transferred down the funding chain: from the Treasury to departments, from departments to local authorities, from local authorities to commissioned providers. Charities sit at the bottom of this chain. They have nowhere to transfer the risk to except their own reserves and their own staff.
There is also a procurement argument. Competitive tendering is designed to deliver value for money. If contracts included guaranteed inflation uplifts, the argument goes, providers would have less incentive to manage costs efficiently. This argument carries less weight when applied to charities delivering essential services to vulnerable people, where "efficiency" often means fewer staff, shorter sessions, and longer waiting lists.
The compounding effect
What makes the absence of inflation adjustment particularly damaging is that it compounds. A 3% annual cost increase on a contract that is not uprated results in a cumulative real-terms cut of approximately 14% over five years. At 5% annual inflation, the five-year cut exceeds 22%. For charities on contracts that were already below full cost recovery when they were signed, the compounding effect can reduce effective funding to a level where safe delivery becomes questionable.
This is not hypothetical. The Institute for Government noted in its analysis of public spending that real-terms per-capita spending on many local services fell by 20-30% between 2010 and 2020, even before the inflationary shock of 2022-24. Charities delivering those services experienced the same squeeze, magnified by their inability to raise prices in the way a commercial provider might.
The evidence
The evidence base is fragmented because no single body tracks inflation adjustment across the full range of government-charity contracts. However, the available data paints a consistent picture.
NCVO's annual Civil Society Almanac shows that government income to charities has been broadly flat in cash terms for much of the past decade, while costs have risen significantly. In real terms, government funding to the voluntary sector remains below its 2009-10 peak. The shift from grants to contracts, documented by NCVO over successive editions, has further reduced charities' ability to manage inflationary pressures because contracts typically offer less flexibility than grants in how money is spent.
The Lloyds Bank Foundation's research on small and medium-sized charities found that organisations with income between £100,000 and £1 million are disproportionately affected by static contract values. These charities lack the scale to cross-subsidise from other income streams and the negotiating leverage to secure better terms. Many reported accepting contract renewals at the same nominal value as the original agreement, knowing this represented a real-terms cut, because the alternative was losing the contract entirely.
Pro Bono Economics has modelled the cumulative impact of cost pressures on the charity sector, including the interaction between inflation, employer NIC increases, and static funding. Their analysis suggests that the sector faces a structural funding gap that cannot be closed through efficiency savings alone. The gap is a function of policy choices about how public money flows to the organisations that deliver public services.
Research by the Charity Finance Group found that fewer than a third of charities surveyed had contracts that included any form of inflation adjustment clause. Among those that did, the uplifts offered were frequently pegged to GDP deflator rates rather than actual cost inflation, resulting in adjustments that fell short of real cost increases.
Current context
The period from 2022 to 2026 has brought the inflation adjustment problem into sharp relief. CPI inflation peaked at 11.1% in October 2022 and remained above 6% throughout 2023 before gradually declining. For charities locked into fixed-price contracts signed before the inflationary surge, the impact was immediate and severe. Services designed to run on 2019 or 2020 cost assumptions were suddenly facing 2023 prices with no mechanism for adjustment.
The employer NIC increase from April 2025, which added an estimated £1.4 billion in costs across the charity sector, compounded the problem. Charities delivering government-commissioned services had no route to recover these additional costs from their commissioners. NCVO and ACEVO both highlighted inflation adjustment as a priority issue in their submissions to the 2025 Spending Review, calling for multi-year contracts to include mandatory inflation clauses linked to actual cost indices.
The Civil Society Covenant, published in July 2025, included commitments to fairer funding practices, but stopped short of mandating inflation adjustment in government contracts. Whether the covenant's principles translate into changed commissioning behaviour at local authority level remains an open question. The National Audit Office's work on value for money in public service commissioning has acknowledged the tension between fixed-price contracting and the sustainability of provider organisations, but systemic reform has not yet followed.
The 2025 Spending Review settlement provided some additional funding for local government, but the extent to which this flows through to uprated contract values for charity providers is not yet clear. Early indications from sector surveys suggest that most charities have not received inflation uplifts on existing contracts.

What this means for charities
For charity leaders, the absence of inflation adjustment is not an abstract policy question. It is a line on the management accounts that gets harder to explain each year. The practical response requires action at both organisational and collective levels.
At the organisational level, charities should build inflation modelling into every contract negotiation and grant application. This means presenting funders with costed scenarios showing what delivery looks like at year-one prices versus year-three or year-five prices without adjustment. It means including explicit inflation clauses in contract proposals and, where commissioners resist, documenting the real-terms reduction in writing so that it is visible rather than hidden.
Trustees have a governance responsibility here. A board that approves a five-year contract with no inflation adjustment is accepting a declining funding position for the duration of that contract. This should be a conscious, documented decision with a clear plan for how the shortfall will be managed, not an unexamined default.
At the collective level, charities should support sector bodies in making the case for mandatory inflation adjustment in public service contracts. NCVO, ACEVO, the Charity Finance Group, and Locality have all called for commissioning reform on this point. The more organisations that share data on the real-terms impact of static contracts, the stronger the evidence base for policy change.
The alternative is continued erosion: services cut incrementally, staff posts left unfilled, quality reduced by degrees, until a contract that once funded meaningful provision funds something that is merely nominal.
Common questions
Why don't government contracts include automatic inflation adjustments?
There is no legal or policy barrier to including inflation clauses. The absence is a function of commissioning practice and budget constraints. Local authorities operating under tight financial settlements are reluctant to commit to future cost increases they may not be able to fund. The result is that inflation risk is transferred to providers, with charities least able to absorb it.
How much does inflation erode a fixed contract over time?
At 3% annual inflation, a fixed contract loses approximately 14% of its real value over five years. At 5%, the loss exceeds 22%. At the peak inflation rates of 2022-23, a two-year fixed contract could lose 15-20% of its purchasing power. These are not marginal differences. They represent the equivalent of losing one in every five or six pounds of funding.
Is this different from the full cost recovery problem?
Related but distinct. Full cost recovery concerns whether a contract covers all the costs of delivery, including overheads, at the point it is signed. Inflation adjustment concerns whether the contract maintains its real value over time. A contract can achieve full cost recovery in year one and still represent a significant real-terms cut by year three if it is not uprated. The two problems compound each other: a contract that starts below full cost and is never adjusted for inflation deteriorates rapidly.
What can small charities do about this?
Small charities have less negotiating power individually, but they can take practical steps. Presenting commissioners with transparent cost models that show the impact of inflation over the contract term makes the issue visible. Joining infrastructure bodies and participating in collective advocacy amplifies the message. And in some cases, the responsible decision may be to decline a contract that cannot be delivered sustainably, difficult as that is when services and service users are at stake.
Has the Civil Society Covenant changed anything?
The Civil Society Covenant, published in July 2025, established principles for a fairer relationship between government and the voluntary sector, including commitments on funding practices. However, the covenant is a framework, not a regulation. It does not mandate inflation adjustment in contracts, and its impact depends on whether commissioners at national and local level adopt its principles in practice. Early evidence suggests implementation is uneven.
