Start with cause, not charity
The best giving decisions begin with a question, not a Google search: what do you actually care about? The charity landscape in England and Wales alone runs to well over 160,000 registered organisations. Narrowing the field by cause — homelessness, cancer research, wildlife conservation, local food banks — gives you a workable shortlist before you've opened a single annual report.
This matters because the field within any cause is rarely flat
This matters because the field within any cause is rarely flat. A dozen charities may all claim to tackle food poverty, but they operate at different scales, in different geographies, with wildly different track records. Starting from cause lets you compare like with like, rather than pitting a national hospice against a community arts project. There is no universal ranking of "best charity" — there is only the best fit between your values, your geography and the evidence available.
Once you have a shortlist, resist the pull of the biggest name. Brand recognition is a product of marketing spend, not necessarily of impact. The Charity Commission registers small local organisations with powerful, focused work alongside household-name charities that spend heavily on fundraising and communications. Neither size tells you whether the work is good; it only tells you how well-known the charity is.
The checks worth doing
1. Confirm it's registered
For England and Wales, the Charity Commission maintains a free, searchable public register at gov.uk. Scottish charities register with OSCR; Northern Irish charities with the Charity Commission for Northern Ireland. A registered charity number is the first piece of evidence that an organisation has met basic legal requirements and is subject to ongoing regulatory oversight.
That said, registration is a floor, not a ceiling. Being on the register tells you a charity is legitimate; it does not tell you whether it is effective. The real due diligence begins after you have confirmed the number.
A note on CASCs: Community Amateur Sports Clubs can also be registered with HMRC and claim Gift Aid. They appear differently on the register, but a genuine CASC registration is a legitimate credential. The key is that something ties the organisation to a regulatory body — unregistered appeals and crowdfunding pages for unnamed causes are where fraud risk rises sharply.
2. Read the accounts — really read them
Every registered charity above a certain income threshold must file accounts with its regulator, and those accounts are publicly available. You do not need an accounting qualification to get useful information from them. Look for three things.
Income and how it is raised. Where does the money come from? Charities heavily dependent on one grant or one donor carry risk; diversified income — from individuals, trusts, contracts and earned income — is generally more resilient.
What is actually spent on the charitable purpose. The accounts will break down expenditure between charitable activities (the work itself), fundraising and administration. A charity spending the great majority of its budget on its stated purpose is doing what it says. The relationship between admin costs and charity effectiveness is more nuanced than it first appears — some overheads represent investment in quality, not waste — but a charity spending more on fundraising than programmes is worth a hard look.
Reserves policy. Does the charity hold reserves? How much, and why? A charity with no reserves is fragile; a charity sitting on a decade's worth of income with no stated reason is hoarding rather than deploying. A published reserves policy, clearly explained, is a good sign of a well-governed organisation.
3. Look for evidence of impact
This is harder than checking the accounts, but more important. Accounts tell you how money was spent; impact evidence tells you whether spending it achieved anything.
Good charities report outcomes, not just activities. There is a meaningful difference between "we distributed 10,000 meals" (an output) and "we helped 2,400 people move into stable housing" (an outcome). The best organisations go further still, using comparison data or independent evaluations to show that their intervention — rather than background trends — produced the result.
You will not always find gold-standard randomised trial evidence, and you should not automatically distrust charities that lack it. Randomised controlled trials are expensive and not always appropriate for the work charities do. What you can reasonably expect is honest reporting: acknowledgement of what did not work alongside what did, clear explanation of the methodology used to count beneficiaries, and a genuine attempt to connect spending to results.
Charities that only report upward numbers — every year an increase, every metric positive — should be read with mild scepticism. Real charitable work is difficult. Honest organisations say so.
4. Assess the leadership and governance
The Charity Commission's register shows who the trustees are. Trustees are the people legally responsible for a charity's direction and conduct; they serve voluntarily and are accountable to the regulator. A diverse, engaged board — one that includes people with relevant expertise as well as lived experience of the issues the charity addresses — is a meaningful quality signal.
You can also look at staff leadership through LinkedIn or the charity's own website. Long tenures at the top can be a strength (deep expertise, institutional knowledge) or a risk (entrenchment, lack of accountability). What you are really looking for is evidence that the organisation is governed — that someone is asking hard questions, reviewing performance and holding leadership to account.
Finally, check whether the charity has faced any regulatory action. The Charity Commission publishes inquiries, regulatory cases and serious incident reports. A past inquiry is not necessarily damning — sometimes charities self-report problems, which is a sign of good governance — but a pattern of complaints or unresolved concerns is a red flag.
5. Ask simple questions
Do not underestimate the value of contacting a charity directly. A well-run organisation will respond promptly, answer questions honestly and point you to its annual report or impact data without hesitation. Evasion, vague answers or pressure to give quickly are warning signs.
Ask: What does my gift specifically fund? How do you measure whether it works? Can I see your most recent accounts? These are reasonable questions. Any charity worth your support will welcome them.
Competence, cost and cause — weighed together
None of these checks happens in isolation. A charity working in a neglected cause area — one where few others are active and where need is severe — may be worth supporting even if its reporting is less polished than a major national organisation's. A charity tackling a well-funded cause, with strong competition and plenty of alternatives, needs to clear a higher bar to justify your choice.
Cost matters, but not as a single number. The relevant question is not "what percentage goes on admin?" but "how much good does a pound achieve?" A charity with slightly higher overheads that delivers a well-evidenced, life-changing programme may represent far better value than a low-overhead organisation doing something measurable but shallow.
The most useful frame is simply: do I trust this organisation with my money? Trust is built from a combination of regulated legitimacy, financial transparency, honest impact reporting and responsive leadership. No charity will score perfectly on every dimension. What you are looking for is a coherent, honest, well-governed organisation that takes your money seriously — and can show you why.
