WATER FIRMS ORDERED TO PAY BACK CUSTOMERS £158M – Ofwat says water companies must pay due to poor and disappointing performance

Water firms in England and Wales have been ordered by regulator Ofwat to return £158m to customers due to their poor performance. Ofwat said the money would come off bills for households and businesses in 2025-26, with the total rebates set to be calculated in December.

Last year, the water regulator ordered firms to repay £114m as part of a similar move.

Ofwat said the results of its annual report on water company performance showed “disappointing results” and that money alone was not enough to address the problems facing the industry.

The regulator also warned that firms were “falling further behind on key targets”, with nine out of 11 suppliers experiencing an increase in “pollution incidents” in 2023.

It comes as water bills in England and Wales are set to rise by an average of 21% over the next five years.

Ofwat’s report also found that while there had been progress made on leaks, firms had only managed a 6% annual reduction – against a target of 16% by 2025.

However, four water companies – South East Water, South West Water, Thames Water and Yorkshire Water – were upgraded by the regulator from “lagging behind” to “average”, but it said performance improvements were inconsistent across the sector.

Anglian Water, Welsh Water and Southern Water were all categorised as “lagging behind”.

No firm managed to achieve the regulator’s top rating of “leading”.
