Running a charity in the UK means balancing mission with money, and a sound budget is where the two meet. Without a realistic plan for income and expenditure, even the most worthwhile causes can drift into financial difficulty, leaving trustees exposed and beneficiaries let down.
I've seen charities of every size wrestle with this, from village hall committees to national organisations, and the pattern is usually the same: the ones that take budgeting seriously tend to weather shocks far better than those that treat it as an afterthought. This page walks through how to prepare a charity budget that actually reflects your work, how to manage spending sensibly once the year is under way, and what trustees should be watching for.
It's written for charity leaders, treasurers and trustees who want a practical grounding rather than a theoretical overview. Budgeting well protects your cause, your people and your reputation.
Overview
A charity budget is a financial plan that sets out the money a charity expects to receive and spend across a defined period, usually a financial year. It translates the charity's strategy into numbers, showing where funds will come from, where they will go, and how the trustees intend to keep the organisation solvent while pursuing its objects.
For registered charities in England and Wales, budgeting sits alongside wider duties under the Charities Act 2011 and the Charity Commission's guidance, particularly CC8 on internal financial controls and CC25 on managing charity finances. The budget is not just a spreadsheet for the treasurer.
It's a governance tool that helps trustees meet their duty to act prudently, a communication tool for funders and donors who want to see their money handled responsibly, and an operational tool for staff who need to know what they can spend. A charity budget typically distinguishes between restricted and unrestricted funds, separates core costs from project costs, and builds in reserves in line with the charity's reserves policy.
Key steps
Set your financial goals against the charity's purpose. Start by connecting the numbers to your charitable objects and strategic plan. Decide what the charity needs to achieve financially over the coming period, whether that's growing reserves, launching a new programme, or simply maintaining existing services. Trustees should agree these priorities before any figures are drafted, because the budget is a means of delivering the mission rather than an exercise in its own right.
Review the current financial picture honestly. Before forecasting forward, understand where you stand now. Pull together recent management accounts, the latest annual accounts filed with the Charity Commission, cash flow records and a breakdown of restricted versus unrestricted funds. Look at trends over the past two or three years. This gives you a realistic baseline and highlights patterns, such as seasonal income dips or rising overhead costs, that need to be factored into next year's plan.
Forecast income and expenditure realistically. Project income from each stream separately: regular giving, grants, trading activities, investment returns, legacies and fundraising events. Be cautious with uncertain income and avoid counting grants that haven't been confirmed. On the expenditure side, break costs down by programme, core operations, governance and fundraising. Use actual historic figures where possible and flag any assumptions clearly so trustees can challenge them.
Balance the budget and set clear priorities. Match projected income against projected expenditure and decide how to handle any shortfall or surplus. If income falls short, trustees must decide which activities to scale back, defer or fund from reserves, keeping restricted fund rules firmly in mind. If there's a surplus, agree whether it strengthens reserves, funds new work or reduces reliance on volatile income. Document the rationale for every significant decision.
Approve, monitor and review throughout the year. The budget should be formally approved by the trustees and then actively managed. Compare actual income and spending against budget at each trustees' meeting, investigate significant variances, and be willing to revise forecasts when circumstances change. Reforecasting mid-year is a sign of good governance, not failure. Keep records of decisions so the audit trail is clear for auditors, independent examiners and the Charity Commission if needed.
Q Who is responsible for approving a charity's budget?
Under charity law in England and Wales, the trustees collectively hold responsibility for the charity's finances, including approving the annual budget. The treasurer or finance committee often does the detailed work, and staff may prepare the first draft, but the board as a whole must approve it and can be held accountable if financial management falls short. This duty cannot be delegated away entirely, even when professional staff are involved.
Q How should restricted funds be handled in a charity budget?
Restricted funds must be shown separately from unrestricted funds and can only be spent on the purposes the donor or funder specified. Your budget should clearly identify restricted income alongside the matching restricted expenditure, so it's obvious these funds are not available for general running costs. Mixing them up or using restricted money for unrelated purposes is a serious breach of trust and may need to be reported to the Charity Commission.
Q What level of reserves should a charity budget for?
There's no fixed figure set in law. The Charity Commission expects trustees to set and publish a reserves policy that explains the target level, the reasoning behind it, and how it fits the charity's risk profile. Some charities hold three months of operating costs, others hold more or less depending on income stability, commitments and obligations. The budget should reflect whatever level the trustees have agreed is appropriate.
Q How often should the budget be reviewed during the year?
Most charities review performance against budget at every trustees' meeting, which usually means quarterly at minimum. Monthly management accounts are common in larger organisations. Beyond routine monitoring, a fuller reforecast is sensible whenever something significant changes, such as losing a major grant, receiving an unexpected legacy, or facing sharp cost increases. Regular review allows trustees to respond quickly rather than discovering problems at year end.
Q Do small charities need a formal budget?
Yes. Even charities below the registration threshold or with minimal income benefit from a written budget, and trustees of registered charities are expected to plan finances properly regardless of size. The level of detail should match the scale of the organisation. A small community charity might need a one-page summary, while a larger operation will need detailed departmental budgets, but the underlying discipline of planning income and expenditure applies to all.
Q What happens if a charity overspends its budget?
Going over budget is not automatically a crisis, but it needs prompt attention. Trustees should identify the cause, consider whether reserves can absorb the shortfall, and decide whether to cut spending elsewhere or seek additional income. Persistent overspending may point to deeper problems such as unrealistic forecasting or weak controls. If the charity risks insolvency, trustees have specific duties and should seek guidance quickly, as personal liability can become a concern.
Q How does budgeting link to the charity's annual accounts?
The budget and the accounts are related but distinct. The budget sets out what you plan to do financially, while the accounts report what actually happened. Accounts must be prepared in line with the Charities SORP and filed with the Charity Commission where required. Comparing budget to outturn each year improves forecasting accuracy over time and helps trustees demonstrate sound stewardship to funders, regulators and the public.
Budgeting decisions for a charity carry real weight for trustees, and the right approach depends on your income mix, your commitments and your reserves position.
