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 remains dependent on cash facilities and financing made available by Group companies to enable it to continue in operational existence and to meet its debts as they fall due. The Company's equity position remains positive, standing at £197,992,000 at the end of 2024. The Group is presented regular financial information on the development of the Stublach site as well as the medium-term business plan and has indicated its continued support for the Company. The Directors have considered the forecasts of the Company included in its medium term business plan, and believe it is therefore appropriate to prepare financial statements on a going concern basis.”
Significant events
- “The development of the Deal Farm Biogas anaerobic digestion plant in Norfolk remained on hold due to planning related issues with minimal expenditure. In November 2024, the business lost an appeal at a public inquiry, resulting in the site being dismantled in 2025.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers
