Severn Trent’s customers in the Midlands and Mid Wales will continue to enjoy the lowest average combined bills in Britain for the eighth year in a row.

The company, which has also reduced sewer flooding by half in the past year, has confirmed that its bills for the coming 12 months will continue to be less than £1 a day - at a time when it is also investing billions of pounds in its water and waste network.

Liv Garfield, Severn Trent’s chief executive, said: “We’re delighted that our customers will continue to enjoy the lowest average bills in the land, especially at a time when we know things are hard for some people.

“Our absolute priority is to improve our services for all of our customers in those areas that matter most to them, while also helping those people who are least able to afford our services.

“That’s why it’s so lovely to see that, alongside our service improvements, we’ve also beaten our target of helping 50,000 of our vulnerable customers with their bills.”

As well as reducing sewer flooding, the company has also seen a 12 per cent reduction in water quality complaints, and has invested £324 million across the region in the last six months alone.

Two of the biggest projects the company is currently investing in are the £300m Birmingham Resilience Project to provide the city with an alternative water supply, and a £60m scheme in Newark to protect 400 homes and businesses from flooding and to simultaneously replace water pipes in the town.

Other recent announcements by Severn Trent confirmed the company’s plans to reduce its impact on the environment. The company is now self-generating the equivalent of 38 per cent of the energy it uses, helping keep customer bills lower by reducing power costs, and it plans to replace its fleet of vans with alternative fuel vehicles when feasible.
