Financial Trend

Annual Returns

As filed with the Charity Commission for England and Wales. Most recent filing covers the financial year ending 2023.

One or more years show a significant change in income (over ±100%) compared with the prior year. This usually reflects a merger, transfer of activities, restated accounts, or a one-off legacy — not necessarily a real change in operating scale. See the methodology for context.
