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.
What the accounts disclose
“publishing revenues have held steady in a changing market, they now comprise 59% of our total income”
“As at 28 February 2026, free reserves were £0.4m, which is below our target due to the temporary timing difference in the purchase and sale of our headquarters.”
“RES Trading Limited, a wholly owned subsidiary of Royal Entomological Society of London, is incorporated in England and Wales (unlisted investments).” — page 36
