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

Margins divide P&L lines by turnover. Gearing is liabilities over total assets. Current ratio is current assets over creditors falling due within one year. Interest cover is operating profit over absolute finance costs. Sector-distribution context coming next.

Going concern

Affirmed

“The financial statements are prepared on a going concern basis which has been supported by the provision of a parental letter of support from SSE plc. The Group letter of support confirms that the Group will provide support to 31 December 2026 where required. The Directors are satisfied that the Group has the ability to provide this support, should it be required.”

Significant events

• “In December 2024, Coire Glas reached a significant milestone with the completion of its £100m exploratory works programmes which saw it complete a 1.2km tunnel into the hillside. March 2025 saw Ofgem and DESNZ jointly published a high-level design of the long-duration electricity storage cap and floor scheme.”
• “In June 25 Coire Glas submitted a pre-qualification application into Ofgem's Long duration electricity storage scheme with application outcomes due to be received back late September 2025. Subject to satisfying the pre-qualification requirements and Ofgem designing Window 1 in a manner which is commercially viable for Pumped Storage Hydro, then Coire Glas will submit a full project assessment in Q4 2025.”
