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

- Affirmed
“The Company's business activities, together with a review of the business and the impact of the principal risks and uncertainties have been described in the strategic report. For the year to 31 March 2025 the company made a profit amounting to £16,588,000 and had net assets of £97,335,000. Although the company is expected to be profitable, the company has also received confirmation from its intermediate parent undertaking, STERIS Limited, of its intention to provide support, where needed, for a period of 12 months from the date of approval of the accounts. The directors have assessed the ability of STERIS Limited to provide support, and therefore have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. Accordingly, the directors continue to adopt the going concern basis of accounting in preparing the financial statements.”
