Audit & accounting basis

Accounting basis: FRS 101
Reporting scope: Standalone (parent only)
Auditor: Deloitte LLP
Audit opinion: Unqualified (clean)
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 results for 2024 were released. 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

“In 2024 Dyno-Rod completed the final year of its 5 Year Good to Great Strategy, achieving strong and consistent performance delivery across its channels. 2024 visit demand was down slightly... In Key Accounts and Wet Works demand was up, while Central Heating systems works and Dyno-Rod direct were broadly flat. Average order values were up.”
“2025 sees the launch of the new 5 Year Vision and Strategy across the business. This has been built on the excellent delivery of the prior strategy and its completion at the end of 2024.”

Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers

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
