Ofwat letting water firms charge twice to tackle sewage, court to hear

River Action bringing legal action against water regulator over who should foot bill for firms' past failures to invest

Ofwat is unlawfully allowing water companies to charge customers twice to fund more than 100bn of investment to reduce sewage pollution, campaigners will allege in court on Tuesday.

Lawyers for River Action say the bill increases being allowed by Ofwat - which amount to an average of 123 a year per household - mean customers will be paying again for improvements to achieve environmental compliance that should have been funded from their previous bills.
