Britain's biggest water company, Thames Water, says it wants to increase every household bill by £29 to cover what it says are unexpected extra costs.

The company, which has 14 million customers, is asking permission from the water regulator, Ofwat, to charge more in order to pay for maintenance work, and costs associated with a major new sewer, the Thames tideway tunnel.
