- Reporting scope
- Standalone (parent only)
- Auditor
- PricewaterhouseCoopers LLP
- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“The Directors have confirmed that after due enquiry they have sufficient evidence to support their conclusion that the Company is a going concern and has adequate resources in the foreseeable future to meet its on-going obligations, including the servicing of debt holders, as those obligations fall due. Consequently, they have formed the opinion that it is reasonable to adopt the going concern basis in preparing the financial statements.”
Significant events
- “At 1 October 2024 NESO was acquired by the UK government, and hence now is a publicly owned company.”
- “On 31 May 2024, ultimate control of BIF transitioned to BIIF Holdco Limited, Stephane Grandguillaume, John Cavill and Antoine Matton.”
- “On 4 December 2024 Mitsubishi Corporation which is incorporated in Japan sold 100% of its shareholding in DTUK to DTUK BLK Bidco Holdings Limited (DTUKBBH). The ultimate controlling party of DTUKBBH is BlackRock Inc.”
- “The Directors have agreed with the Company's auditors that the auditors' liability to damages for breach of duty in relation to the audit of the Company's financial statements for the year to 31 March 2025 should be limited to the greater of £5 million or 5 times the auditors fees, and that in any event the auditors liability for damages should be limited to that part of any loss suffered by the Company as is just and equitable having regard to the extent to which the auditors, the Company and any third parties are responsible for the loss in question. The shareholders approved this limited liability agreement, as required by the Companies Act 2006, by a resolution dated 29 January 2025.”

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
