Isle of Wight utility firm, Southern Water, must pay out £28.3 million pounds after missing its targets on water treatment works compliance, pollution incidents and internal sewer flooding in 2021/22.

Industry regulator Ofwat has revealed it must reduce our bills accordingly.

UPDATE: Here's the statement from Southern Water: Isle of Wight water firm reacts to Ofwat's £28.3 rebate call

It is not alone, as Thames Water, must pay £51 million.

Ofwat has listed Southern Water as being among the poorer performing companies that it oversees.

  • The bill reduction will be felt in the 2023/2024 financial year and Ofwat's decision is now out for consultation until October 21.

In all, 11 companies have missed targets, but not all are required to reduce bills.

David Black, Ofwat CEO, said: "When it comes to delivering for their customers, too many water companies are falling short, and we are requiring them to return around £150m to their customers. 

"We expect companies to improve their performance every year; where they fail to do so, we will hold them to account.

"The poorest performers, Southern Water and Thames Water, will have to return almost £80m to their customers.

"All water companies need to earn back the trust of customers and the public and we will continue to challenge the sector to improve."
