Ofwat has told the Competition and Markets Authority “we stand by our PR24 determinations” as the competition regulator begins the process of examining requests by five water companies to review Ofwat’s decisions on their AMP8 business plans.

Fitch Ratings says it sees moderately higher business risk in AMP8, mainly driven by heightened exposure to environmental risk, increasing public scrutiny, and higher clawback risk, which is linked to the price control deliverables (PCDs) mechanism.
