I heard the news today. Thames Water have applied to Ofwat to be allowed to increase their prices, in breach of an agreement not to do so until 2015. One of the reasons given is that they're losing money because poorer people are failing to pay their bills.
(Meanwhile, thousands of gallons are pouring down my road from a leak at the top, and have been for eight hours or more. No sign of any repair work. What a waste. Could have been used for fracking.)
