Notice of appeal
26 February 2025: Castle Water Limited (Castle Water) applied for permission to appeal Ofwat’s decision of 5 February 2025 to reject Castle Water’s request for a change to the Wholesale Retail Code. Castle Water proposed to amend section 9.11 of the Wholesale Retail Code to relieve retailers of the obligation to provide credit support to a wholesaler where, and for so long as, that wholesaler does not have a stable credit rating of BBB/Baa2 or higher.
The administrative timetable for the CMA’s decision whether to grant permission to appeal can be found above. If permission to appeal is granted, the CMA has 30 working days following the date it receives the Ofwat’s reply, to determine the appeal. This deadline can be further extended by 10 working days where there are good reasons for doing so.
This appeal process relates to arrangements between water wholesalers and retailers who in turn supply the business retail market. It is not part of the PR24 process relating to the CMA’s redetermination of Ofwat’s price control decision.
