FY2026

Financial health, per its FY2026 accounts

The charity reported a minor net deficit of £45,759 for the year, driven by a 29% rise in expenditure to £2.16 million, largely due to the acquisition of a new London headquarters and staff restructuring. However, this was substantially offset by £519,893 in net investment gains, and the charity maintains a robust financial foundation with total funds exceeding £21 million. While free liquid reserves temporarily dropped to £413,157 due to a bridging loan for the property purchase, the trustees state this timing difference will be resolved upon the pending sale of the previous headquarters, Mansion House.
