- Going concern
- Affirmed
“The Directors of the Company have prepared the Financial Statements on a going concern basis which assumes the Company will continue in operation for at least 12 months from the date of approval of the Financial Statements and be able to meet its obligations as they fall due. In forming this judgement the Directors have taken account of the current and forecast trading performance of the business for the period to 31 December 2026, including taking account of reasonably possible changes in trading performance and the likelihood of the renewal/replacement of key contracts which expire within that year. The nature of the Company's contracts enables it to be consistently cash generative. Management's forecasts indicate that this is expected to continue throughout the forecast period. After considering the factors as set out above, the Directors have a reasonable expectation that the Company has access to sufficient financial and other resources to continue in operational existence for the foreseeable future that is at least twelve months from the date of approval of these Financial Statements. Accordingly, the Directors believe that it is appropriate that these Financial Statements are prepared on a going concern basis.”
Significant events
- “The Company paid a dividend of £220m on 30 May 2025 at £628.57 per share. This dividend was an interim dividend with respect to the 2024 financial year. The Directors do not propose the payment of a final dividend (2023: £nil).”

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
