The water companies have expressed disappointment at regulator Ofwat’s response to their proposed capital investment plans covering 2010-2015.
Ofwat has just published its draft determination outlining major cuts in some water companies’ spending plans, and calling for cuts in customers’ bills.
The regulator has sanctioned £21B investment in the industry.
Its prosposals include cutting Thames Water’s planned £5.5B spend to £4.6B over the next five years.
Ofwat has also nearly halved the company’s proposed water mains replacement programme that, according to Thames Water, will result in no leakage reduction over the next five years.
