PN 03/15: Ofwat welcomes CMA’s final decision on Bristol Water’s price determination appeal


Ofwat today welcomed the outcome of the Competition and Markets Authority’s (CMA) thorough investigation into Bristol Water’s appeal against its price determination. The CMA’s final decision substantially supports and reaffirms Ofwat’s process for setting price limits during the 2014 price review.

When Ofwat set price limits for Bristol Water in December 2014 these provided that the customers of Bristol Water should see a 19% reduction in their average bill by 2020 to £155. Bristol Water appealed that decision to the CMA, arguing the reduction should be less.

Following the CMA’s decision, average bills will now reduce by 16% by 2020. This compares with Bristol Water’s original plan, signed off by its Board, which would have reduced bills by only 6%.

This means average bills will be £160 per year, compared with £187 had Bristol’s case been accepted.

It is now for Bristol Water to challenge itself to improve, and look closely at the way that it runs its business in the future. It needs to deliver a much more efficient service, at a lower cost whilst ensuring that it keep its customers at the heart of its decision making.

Cathryn Ross, Ofwat’s Chief Executive said:

“We welcome the CMA decision. The price review process challenged companies to focus on customers and seek improvements across the whole of their operations.  It delivered real benefits to customers across England and Wales, including a 5% reduction in average bills and continued investment in services to the tune of £44 billion over the next five years.

“While the CMA has slightly reduced the level of bill reductions we set this is still an excellent result for Bristol Water’s customers. It is critical that Bristol Water continues to deliver a safe and secure water service to its customers.

“We hope that Bristol Water will now review its approach to our five-yearly price reviews and take forward these lessons at future reviews.”

Ofwat is now seeking for the CMA’s report to be published, consistent with the transparent process Ofwat undertook in its 2014 price review, and to ensure customers have all the relevant information in respect of their water service.

In future, in its work running up to the next price review in 2019, Ofwat will be putting still more emphasis on companies taking account of their customers’ priorities through customer engagement. Ofwat believes companies should serve their customers in a manner that respects customers’ priorities and aspirations for the services they receive at a price they accept.
