Anglian Water is the worst-performing water company for self-reporting pollution incidents, a new report has revealed.

The company, which is £6.6 in debt, has been told it needs to improve after the Environment Agency handed it a two-star rating in its annual report on Wednesday.

The rating was due in part to it being fined £5.5m in 2022.

Anglian Water, which received the same rating in 2021, was responsible for 33 sewage pollution incidents per 10,000km.

It also caused 255 incidents in 2022, including 11 serious incidents, according to the Environment Agency.

A spokesperson said: "In terms of our financial stability, Anglian Water has a robust financial platform in place which was recognised as part of Ofwat’s financial resilience report last year, and by the three largest corporate credit rating agencies.

"This enables the delivery of our largest ever capital investment programme – which is centred on building a resilient business, delivering environmental improvements across our region, and supporting our customers.

“Over the last two years we’ve drastically changed how we operate to address more effectively the unique and complex challenges facing our region.

"We know that we must do better on some critical measures of environmental performance, and we remain resolutely focussed on continuing with this strategy at pace.”

Our credit rating is one of the strongest in the sector with all three of the major credit ratings agencies, (Moody’s, Fitch and S&P) classifying Anglian Water as A-. As such we are one of the most financially secure companies in the water industry.

Anglian Water told county councillors earlier this year that it would take “decades” and millions of pounds to install the infrastructure to stop raw sewage being released into Norfolk rivers.
