Audit & accounting basis
- Accounting basis
- IFRS
- Reporting scope
- Standalone (parent only)
- Auditor
- Johnston Carmichael 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 compliance with all debt covenants and servicing of debt holders, as those obligations fall due.”
Significant events
- “The Company enjoys certain protections afforded under the licence granted to the Company. In particular, provided that the Company can demonstrate that it has applied good industry practice in the management of the Company and its assets, then in the event that an unforeseen incident results in the Company suffering a loss in excess of £1,000k [...] it can apply to Ofgem for an income adjusting event.”
- “The Company has RPI swaps with third parties. The use of these RPI swaps has the effect of exchanging the vast majority of variable cash inflows arising from the operation of the Company's transmission assets in exchange for a pre-determined stream of cash inflows from these third parties.”
- “As part of the Company's commitment to Environmental, Social and Governance ("ESG") principles, charitable donations of £1k were made during the year (2024: £1k).”

Each % is (latest − prior) ÷ |prior| for the line item as filed. Periods don't have to be exactly 12 months apart — a long or short period (typical around incorporation or year-end changes) will distort the comparison. Lines a company doesn't report are omitted. About these numbers
