# How to choose between two similar charities

**In short:** Compare charities on delivery model and scale first, then use filings to check resilience and administration. A smaller charity often does more with your £50 than a national one; a national one may be better placed for research or campaigning.

Data from [Charity Commission register](https://register-of-charities.charitycommission.gov.uk/), last updated 25 July 2026.

Two charities, same cause, similar names, and no obvious way to choose. This is where most giving decisions actually stall. The method below takes about ten minutes and separates the things filings can tell you from the things only the charity can. For the wider UK playbook — why charity comparisons matter, worked examples, and common mistakes — start with [how to compare charities in the UK](https://www.charitycompare.org.uk/guides/how-to-compare-charities).

## Step 1: Work out what you want your money to do

Charities on the same cause often do quite different work. For a single illness you might find:

- a **research funder** paying for trials and lab work,

- a **service provider** running nurses, helplines or hospice beds,

- a **campaigning organisation** pushing for policy change,

- a **local support group** running peer groups in one county.

None is more legitimate than another, but they suit different intentions. Research is slow and cumulative; direct services help identifiable people now; campaigning can change outcomes for far more people, less predictably.

Read each charity’s stated purpose and the “how we spend” section of its annual report before comparing any numbers.

## Step 2: Compare scale honestly

Scale drives almost every financial difference between charities, so compare like with like:

- **A £50 donation** to a £150k local charity is a meaningful share of its income. The same gift to a £200m national charity is a rounding error in its accounts, though it may still buy a defined unit of work.

- **Large charities** have professional finance, safeguarding and audit functions, so overheads look higher — and their controls are usually stronger for it.

- **Small charities** rely more on volunteers, and are more vulnerable to losing one grant or one key person.

If you want to see where a modest donation goes furthest, our [hidden gems](https://www.charitycompare.org.uk/hidden-gems) list surfaces smaller charities with strong filing records.

## Step 3: Use the filings for resilience and administration

This is what public accounts are genuinely good for. Compare:
| What to compare | Why it matters |
| --- | --- |
| Share of expenditure on charitable activities | How much of each pound reaches the work |
| Reserves in months | Resilience; very low is fragile, very high may mean unused funds |
| Fundraising cost per £1 raised | Efficiency of income generation, judged against age and model |
| Filing record | The cheapest available proxy for competent administration |
| Trustee board size | Whether decisions are genuinely scrutinised |
| Income trend over five years | Growing, stable or shrinking |

The [comparison tool](https://www.charitycompare.org.uk/compare-charities) puts up to four charities against these metrics from UK regulator filings, so you do not have to open four sets of accounts.

## Step 4: Read the trustees’ annual report

The report is where a charity explains itself, and its quality is informative in its own right. Strong reports state what was achieved with numbers, name what did not work, and explain unusual figures. Weak reports describe activity without outcomes and go quiet exactly where the accounts look strange.

## Step 5: Decide, then commit

Once you have chosen, giving **regularly** is worth more than the same amount given sporadically: it costs the charity less to administer, it makes planning possible, and it avoids repeated fundraising spend to re-acquire you as a donor. Adding [Gift Aid](https://www.charitycompare.org.uk/guides/gift-aid-basics) increases the value by 25% at no cost to you.

## What none of this tells you

No filing shows whether a charity’s programmes actually change lives. Cost-effectiveness research exists for some interventions — particularly in global health and development — but for most UK charities it does not. Be honest that you are choosing on **accountability, resilience and fit with your intentions**, not on measured impact.

That is precisely the boundary the [Clarity Score](https://www.charitycompare.org.uk/methodology) draws: it scores what the filings show, caps ratio-based scoring at 20 of 100 points, and states plainly that it is not an impact measure.

## Common questions

### Is it better to donate to a small or large charity?

+ It depends on what you want your money to do. A small local charity feels a modest donation more keenly and often delivers direct services cheaply, while a large national charity can fund long-term research, influence policy and absorb emergencies. Neither is inherently better run — scale changes the cost structure, not the integrity.

### Should I give to one charity or several?

+ Concentrating gifts on one or two charities reduces their fundraising and administration cost per pound received, and regular giving is worth more to a charity than the same total given sporadically. Spreading donations widely mainly helps if you want to support genuinely different causes.

### How do I compare two charities that do the same thing?

+ Put their filings side by side and look at scale, share of expenditure on charitable activities, reserves in months, and filing record — then read each trustees' annual report to understand the delivery model. CharityCompare's comparison tool shows up to four charities against the same metrics from UK regulator filings.

### Does a higher Clarity Score mean a charity is more effective?

+ No. The Clarity Score measures how clearly and responsibly a charity accounts for its money, using regulator filings. It does not measure the real-world impact of programmes, which no filing captures. Use it to rule out weak administration, then judge impact from the charity's own reporting.
