Severn Trent Plc ("Severn Trent" or "the Company")

Preliminary Announcement of Annual Results

£1.9 billion of capital invested with performance incentives ahead of expectations and upgraded earnings outlook

James Jesic, Chief Executive, said:

 "This has been another year of exceptional growth. We have invested £1.9 billion to deliver long-term benefits for our Severn Trent Water customers, increasing the scale of our investments by over 60% in two years. Our unique strength of internal capabilities coupled with strong supply chain relationships have enabled acceleration of investment delivery and growth in our water and wastewater infrastructure. 

"I understand how vital it is we deliver for the local communities we serve and the responsibility we have to the people, businesses and public services depending on us for their water and wastewater services every day. More broadly, we are helping around 330,000 households with their bills and reaching over 15,000 people through employability support programmes.

"We continue to deliver meaningful outcomes for over 9 million people, while maintaining exceptional water quality standards and enabling economic growth in our region. Our investments are driving environmental improvements, including a 41% year-on-year reduction in average spills from storm overflows. There is more to do, and with the strength of our performance culture, I am excited by our ability to deliver for all stakeholders on the opportunities ahead."
