Audit opinion
Unqualified (clean)
Going concern
Affirmed

“Under the Energy Act 2004, the NDA has a statutory obligation to provide adequate funding to enable the Company to manage risks and keep the operations of the Company safe and secure. The Directors will therefore, as with previous years, work with the NDA to manage the Company's funding requirements. The Directors are confident that the use of the going concern basis of accounting remains appropriate in the preparation of the Financial Statements, recognising that there is a reasonable expectation that the Company would have adequate resources to continue in operation for at least the next 12 months from the point of approving the Financial Statements 2024/25.”

Year-on-year

FY2024 → FY2025 · period ending 2025-03-31 vs 2024-03-31

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
