Separate measures from the charity's own returns and accounts, each with its year. Read them together: no single measure says how well a charity is run.

From the annual returns the charity filed with the Charity Commission. The largest funder comes from its accounts, read by AI.

Government grants in the year ending 31 December 2025: Not reported. Government contracts: Not reported.

From the charity's annual return to the Charity Commission, which asks every charity with income over £10,000 how much came from government grants and contracts. It does not say which part of government. These totals are separate from the named funders read from its accounts and the grants published on 360Giving, and are not added to them.

In its accounts for the year ending 31 December 2025, the charity named 5 funders who gave £830,459 between them. £14,425 of that came from public bodies.

These figures were read from the accounts the charity filed with the Charity Commission by Claude, an AI model, in OpenEconomy's accounts reader. AI can misread a table, so check the accounts on the register before relying on a figure.

Only funding the accounts name with an amount is included. Most charities also have income from donations, fees and trading that is not listed by funder, so this is part of its income.

Funders that publish to 360Giving list 6 grants to this charity since 2004, worth at least £607,888.

Only funders that publish their grants to 360Giving are included, and many do not. These are amounts funders awarded, which can differ from what the charity received in a given year, so they are shown apart from the accounts figures above.

Public bodies' published spending shows 6 payments to this charity worth £596,826 between 5 January 2021 and 28 May 2026.

Councils and Welsh Government publish what they pay suppliers and grant holders above a threshold, usually £500 for councils and £25,000 for Welsh Government, so smaller payments are missing. A payment is shown only when OpenEconomy matched it to this charity with certainty. These figures come from the payer's records. They are a separate measure from the charity's own accounts, 360Giving grants and its annual return, and are never added to them.

9 trustees run the charity.

Of the last 5 annual returns that were due, 4 arrived by the deadline.
