Severn Trent Plc confirms record sixth year of four-star EPA status

Severn Trent Plc is proud to announce that Severn Trent Water has been awarded the highest-possible four-star status in the Environment Agency's 2024 Environmental Performance Assessment ('EPA'). This award marks six consecutive years of industry-leading environmental performance - twice as long as any other water company has ever achieved.

Liv Garfield, Chief Executive, said:

"Being awarded four-star EPA status is testament to the incredible teams at Severn Trent, the focus we place on these metrics, and the real, lasting change we're delivering for the environment. It's the result of hard work, major investment over many years, a real understanding of our infrastructure, and strong collaboration with our partners and communities.

"It's the sixth consecutive year that we have achieved the top-rated award, with a backdrop of tightening environmental standards. One year is a milestone - six years is an industry record, and our teams are proud of it. And with our largest-ever investment programme underway, we're fully focussed on driving the environmental improvements our customers and communities expect."

The EPA is a tool used by the Environment Agency to assess and compare the performance of water companies in England. The assessment currently comprises seven different metrics which tighten every year to drive continued improvement in environmental standards. We are pleased to have maintained the highest-possible four-star status against these increasingly stretching targets.

As part of our delivery of four-star status, in the 2024 assessment period we have:

· Completed 580 environmental improvement schemes, meaning in the five years of AMP7 we have delivered 1,691 Water Industry National Environment Programme ('WINEP') schemes;

· Achieved over 99% compliance with our discharge permits across our 648 wastewater sites;

· Delivered the joint best pollutions performance in the sector, and the best pollutions performance across the past five years, while yet again meeting our serious pollutions and self-reporting targets;

· Achieved 100% compliance on satisfactory sludge use and disposal, meaning we have been 100% compliant in all eight years in which the measure has been live since 2013; and

· Once again hit our target on the Supply Demand Balance Index, which measures the water available for supply compared to potential dry year demand, thanks in part to our best ever leakage performance which has culminated in a leakage reduction of 16.8% across the past five years.

Almost ten months into the 2025 assessment period, we are on track to achieve a seventh consecutive year of four-star environmental performance. A range of initiatives are underway to drive continued year-on-year improvement, including upgrades to over 400 sewage pumping stations, the expansion of our proactive response teams to respond to incidents quickly, and further utilisation of AI to predict pollutions before they occur.
