How much should charities hold in reserve? The tension between prudence and public trust

There is no mandated reserve level for UK charities, but public perception clashes with financial reality. Too much looks like hoarding; too little risks collapse.

By Tom Neill-Eagle

The debate in brief

Every charity needs reserves. They cover cash flow gaps, absorb unexpected costs, and keep services running when income drops. But there is no consensus on how much is enough. The Charity Commission's CC19 guidance explicitly does not set a target level, requiring only that trustees justify whatever they hold. Despite this, a widespread rule of thumb — "three months' running costs" — has become a de facto standard that many trustees, funders, and journalists treat as authoritative.

The public tends to view large reserves as money being hoarded rather than spent on the cause. The sector knows that running on empty is equally dangerous. COVID-19 proved both sides right: charities with thin reserves faced immediate existential crises, while those with substantial funds attracted scrutiny for not spending them fast enough.

Quick takeaways

QuestionAnswer
Is there a mandated reserve level for UK charities?No — the Charity Commission's CC19 guidance requires a reserves policy but does not set a specific level.
What is the "three months" rule?A widely cited rule of thumb suggesting charities should hold three to six months of operating costs. It has no regulatory basis.
How much do UK charities actually hold in reserves?The median small charity holds around three to four months of expenditure, but this varies widely by size and subsector.
Did COVID-19 expose a reserves problem?Yes — the Pro Bono Economics/NCVO COVID tracker found 25% of charities had less than three months of reserves when the pandemic hit.
What does CC19 actually require?That trustees have a policy explaining the level of reserves held, why that level is appropriate, and how they plan to maintain it.
Do funders penalise charities for holding reserves?Some do — grant assessors may reject applicants seen as having "too much" in the bank, creating a perverse incentive to run lean.

The arguments

The case for holding substantial reserves

Charities face financial risks that most businesses do not. Income can be volatile and unpredictable, particularly for organisations dependent on fundraised or grant income. A major donor withdrawing, a government contract ending, or a fundraising event failing can create immediate cash flow crises that threaten services and staff. Reserves provide the buffer that allows a charity to manage these shocks without cutting frontline delivery.

The COVID-19 pandemic made this argument in the starkest possible terms. When lockdowns hit in March 2020, charity shops closed overnight, fundraising events were cancelled, and face-to-face donation channels shut down. A joint survey by the Chartered Institute of Fundraising, the Charity Finance Group, and NCVO estimated that UK charities faced a £12.4 billion income shortfall during the first year of the pandemic. Organisations with healthy reserves could continue operating while they adapted. Those without them faced immediate decisions about redundancies and service closures. The Charities Aid Foundation's Charity Resilience Index found that financial reserves were the single strongest predictor of whether a charity survived the pandemic intact.

Beyond crisis management, reserves fund strategic investment. A charity that wants to pilot a new programme, invest in technology, or expand into a new area needs capital to do so. Running at break-even with no reserves means no capacity for innovation or growth.

The case against excessive accumulation

Public trust in charities depends substantially on the perception that donations are being used, not stored. The Charity Commission's Public Trust in Charities 2025 report found that how much of a donation reaches the cause remains the single most important factor in donor confidence. Large reported reserves sit uncomfortably with this expectation — particularly when a charity is simultaneously fundraising from the public.

This is not just a perception problem. There are legitimate governance questions about whether holding very large reserves serves the charitable objects. Money sitting in bank accounts earning modest interest could be funding services now. The intergenerational equity argument — that today's beneficiaries should not be denied resources so that future beneficiaries might benefit — applies as much to reserves as it does to endowment spending debates.

Media scrutiny can be severe. Investigations by the Daily Mail, the Times, and others have repeatedly highlighted charities sitting on substantial reserves while asking the public for money. Whether or not those reserves are justified, the reputational damage is real and can undermine the broader trust on which the entire sector depends.

The funder double bind

A particularly damaging dynamic exists around funder attitudes to reserves. Many grant-making trusts and statutory funders assess applicants' reserves as part of due diligence. Charities with large reserves may be refused funding on the grounds that they do not need it. Charities with very small reserves may be refused on the grounds that they are financially unsustainable. This creates a narrow band of acceptable reserve levels that bears no relationship to the actual financial needs of the organisation.

The result is perverse: charities are incentivised to keep reserves low enough to remain eligible for funding, even when prudent financial management would dictate holding more. ACEVO has repeatedly highlighted this problem, arguing that funders should assess the adequacy of a charity's reserves policy rather than penalising them for the absolute figure.

The evidence

The Charity Commission's CC19 guidance, last updated in June 2023, is the regulatory starting point. It defines reserves as the part of a charity's unrestricted funds that is freely available to spend. It requires trustees to establish a reserves policy, explain the level of reserves held, and set out plans for maintaining that level. Critically, it does not prescribe a target figure or range.

Data from the NCVO UK Civil Society Almanac 2024 shows that the voluntary sector held total reserves of approximately £88.5 billion in 2021/22, though this figure is heavily skewed by a small number of very large organisations including housing associations and universities. Among smaller charities, the picture is far more varied. Pro Bono Economics and NCVO's COVID-19 charity tracker in 2020 found that around 25% of charities had reserves equivalent to less than three months of expenditure when the pandemic struck, and one in ten had less than one month.

The Charities SORP (FRS 102) requires charities to distinguish between restricted and unrestricted funds in their accounts, and to explain their reserves policy in the trustees' annual report. Despite this requirement, the quality of reserves reporting is inconsistent. A 2019 Charity Commission research report found that only 52% of charities with income over £500,000 provided a "clear and full" explanation of their reserves policy in their annual reports.

The "three months' running costs" figure has no regulatory or academic origin that can be reliably traced. It appears to have emerged as professional shorthand among auditors and advisors, and has been repeated so widely that many trustees and journalists treat it as official guidance. The Charity Commission has never endorsed it.

Current context

The financial pressures on UK charities in 2025-26 make the reserves debate more acute than at any point since the pandemic. The employer National Insurance Contribution increase, estimated by NCVO at £1.4 billion in additional costs for the sector, is squeezing operating margins. The CAF Charity Insights Report 2025 found that only 30% of charity leaders consider the sector to be in a healthy financial position, with 44% citing cost rises as their main challenge.

At the same time, investment returns have been mixed, reducing the growth of reserves held in invested assets. Inflation in 2022-24 eroded the real value of cash reserves significantly — a charity holding the same nominal sum in 2026 as in 2021 has considerably less purchasing power.

The Charity Commission's 2025 public trust research found trust levels remain stable at 6.5 out of 10, but the sensitivity around financial management has not diminished. Charities face the unenviable task of rebuilding reserves depleted during the pandemic and the cost-of-living crisis while simultaneously absorbing new cost pressures — all under the gaze of donors and media who may interpret any accumulation as hoarding.

What this means for charities

The absence of a prescribed reserve level is a feature, not a bug. It reflects the reality that a community transport charity with stable local authority funding has a fundamentally different risk profile from a disaster relief charity dependent on unpredictable emergency appeals. Trustees must assess their own organisation's needs rather than defaulting to a rule of thumb.

A robust reserves policy should explain not just the current level but the reasoning behind it: what risks the reserves are intended to cover, how the target was calculated, and what plans exist to build or draw down reserves over time. The Charity Commission's CC19 guidance provides a framework for this, and charities that follow it are well-positioned to defend their position to donors, funders, and regulators.

Charities should also be prepared to communicate about reserves in plain language. Saying "we hold six months of reserves because our income is volatile and we have contractual commitments to staff and beneficiaries that cannot be switched off overnight" is more compelling than either hiding the figure or apologising for it. Transparency about why reserves are held is the best defence against the accusation that they are being hoarded.

Common questions

What does the Charity Commission's CC19 guidance actually say?

CC19, titled "Charity reserves: building resilience," sets out the Commission's expectations for how charities should manage and report on reserves. It defines reserves as that part of a charity's unrestricted funds that is freely available to spend — excluding restricted funds, designated funds committed to specific purposes, and funds tied up in fixed assets. Trustees are required to have a reserves policy, to explain the level they hold, and to set out how they plan to maintain or adjust it. The guidance does not set a minimum or maximum level. It explicitly states that what constitutes an appropriate level depends on the individual charity's circumstances.

Is three months' running costs the right amount?

There is no evidence-based basis for the "three months" figure, and the Charity Commission has never endorsed it. For some charities, three months would be dangerously low — an organisation with long-term lease commitments, permanent staff, and volatile income may need substantially more. For others, particularly those with stable, predictable funding, it may be more than necessary. The right figure depends on income volatility, expenditure commitments, the speed at which costs could be reduced in a crisis, and the charity's strategic plans. Trustees should calculate their own target based on a risk assessment rather than adopting an arbitrary benchmark.

Can a charity have too much in reserves?

Yes, in principle. The Charity Commission can and does ask questions when charities accumulate reserves that appear disproportionate to their activities and stated objects. Holding very large unrestricted reserves indefinitely, without a clear rationale or plan for their use, may indicate that the charity is not fulfilling its charitable purposes. However, "too much" is always contextual. A charity saving for a building purchase, for example, may legitimately hold several years of income in reserve. The key is that the level can be explained and justified.

Do funders penalise charities for holding reserves?

Many do, either explicitly or implicitly. Some grant-making trusts have policies that exclude applicants with reserves above a certain threshold — often expressed as a ratio of reserves to annual expenditure. Government funders may similarly view large reserves as evidence that additional funding is not needed. This creates a perverse incentive to minimise reported reserves, potentially at the cost of financial resilience. ACEVO and others have called on funders to assess the quality of a charity's reserves policy rather than imposing blanket thresholds.

How did COVID-19 change the reserves debate?

The pandemic was the most significant stress test of charity finances in a generation. A joint survey by the Chartered Institute of Fundraising, the Charity Finance Group, and NCVO projected a £12.4 billion income shortfall for the sector during the first year of the pandemic. The Pro Bono Economics/NCVO COVID tracker found that 25% of charities had less than three months of reserves, and the sector shed an estimated 60,000 jobs. The experience exposed the fragility of organisations running with minimal financial buffers, and prompted the Charity Commission to emphasise the importance of financial resilience planning. But the lesson cuts both ways: charities that had built up reserves were criticised in some quarters for not spending them immediately on crisis response.

Should reserves be held as cash or invested?

The answer depends on the charity's liquidity needs and risk appetite. Reserves intended to cover short-term cash flow gaps should be held in liquid, accessible forms. Reserves held for longer-term strategic purposes can be invested for growth, subject to the charity's investment policy and the requirements of the Trustee Act 2000. The Charity Commission's CC14 guidance on investment covers this territory. The key risk, demonstrated clearly during 2022-24, is that invested reserves can lose value precisely when the charity needs them most — as markets fell during the same period that inflation was eroding operating budgets.
