The Competition & Markets Authority (CMA) has increased the rate of returns for the four companies that appealed Ofwat’s final determinations for the PR19 price control – at 0.54 per cent higher than the regulator’s decision. The CMA this morning published its provisional redetermination of the business plans for Anglian, Bristol, Northumbrian and Yorkshire Water, in which all four also saw an uplift in overall totex allowance and a softer reduction in customer bills over the five years.
