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's Directors have made inquiries and satisfied themselves that there has not been a material change to the Group's going concern assessment since the Centrica Group interim results for 2025 were released on 24 July 2025. On the basis of these enquiries made, and the fact that Centrica plc, the ultimate parent company, has confirmed it will continue to support the Company, the Directors have concluded that the Company should be able to meet its liabilities as they fall due for the foreseeable future, and therefore the financial statements have been prepared on a going concern basis.”

Significant events

• “Engineering for the redevelopment of Rough for hydrogen storage continues and discussions are ongoing with regulators to secure a regulated support model.”
• “The Company has completed all of the preparatory work to enable a £2bn investment to be taken to redevelop Rough for gas and hydrogen storage over the next 45 years, but without a regulatory model to underpin it, we cannot make this investment.”
