Year-on-year

FY2023 → FY2024 · period ending 2024-12-31 vs 2023-12-31

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers

Going concern
Affirmed

“The Company made a profit after tax of £21,664,026 (2023: £214,964,417) for the year ended 31 December 2024 and had net assets of £130,819,816 (2023: £130,857,790) at that date. Having reviewed the Company's and its subsidiary's forecast cashflows for a period of more than twelve months from the date of approval of the financial statements, the directors consider the use of the going concern basis of accounting is appropriate because there are no material uncertainties related to events or conditions that may cast significant doubt about the ability of the Company to continue as a going concern. The directors have reasonable expectation that the Company has adequate resources to continue to operate for the foreseeable future.”
