The industry

The water industry in England and Wales invests more than £3 billion a year and employs over 27,000 people. There are currently 10 water and sewerage companies in England and Wales. Our sector is facing significant long-term challenges. The privatisation of the industry in 1989 led to improvements in services to customers, better quality drinking water and higher environmental standards. Our proposals for changes in the industry are helping us to play a role in shaping the debate about its future.  


Our business

Severn Trent Water is a regulated business.  We work within five year planning cycles, with the prices we charge our customers set at the beginning of each cycle by our economic regulator, Ofwat. These five year cycles are known as Asset Management Plan (AMP) periods.   

How we measure success

Water companies are required to publish performance against a set of indicators.  These indicators provide Ofwat with an overall picture of company performance against the commitments made as part of the AMP6 price review. 

As well as being regulated by Ofwat, our performance is monitored by:

We also work with the Government (including the Department for Environment, Food and Rural Affairs (DEFRA) and the Welsh Government) and other agencies, such as the Consumer Council for Water, Natural England and the Countryside Council for Wales to make sure we meet the highest customer service and environmental standards, while offering customers the lowest prices.
