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.
Thames Water has released the following statement regarding the planned increase in water bills:
"We previously made it clear that bills need to rise to pay for the cost of the Thames Tideway Tunnel and are now able to give our customers advance warning of the likely increase and the timing. Ofwat [the water and sewerage regulator] sets limits on water bills in line with the work that water companies need to do, and will scrutinise the Thames Tideway Tunnel costs to ensure they are kept as low as possible."
