There's evidence that Thames Water's attempts to add 490 million pounds to its customers' water bills has badly backfired. The industry regulator, Ofwat, has refused permission for the rise - and we've learned that the firm could now face a "clawback" of money it has already taken.
Our Consumer Editor Chris Choi explains.
Ofwat's decision to reject Thames Waters' bid to increase prices by 8% is final, but Thames Water could appeal to the Competition Commission.
The company said: "We will review the decision carefully before deciding on our next steps."
Water regulator Ofwat has rejected a bid by Thames Water for an additional price hike for 2014 to 2015 of 8%.
Water regulator Ofwat has turned down Thames Water's application for an additional price increase for 2014 to 2015.
Ofwat says it was for Thames Water to justify the proposed 8% increase was in customers’ interests.
Within the three month timescale for assessing the application, the water regulator found the evidence the company submitted did not justify its proposed £29 additional increase in customers' bills.
Ofwat’s decision means the maximum that Thames can add to customers’ bills for 2014-15 is still 1.4% above inflation, as set in the 2009 price review.
Water regulator Ofwat says it will challenge a request to raise water bills in the capital by 8% next year.
The request by Thames Water could see the average annual bill rise by nearly £30 if it goes ahead.
Thames Water has released the following statement regarding the planned increase in water bills:
