Regulating the environmental performance of the water industry is a core Environment Agency function. Since 2023 we have been transforming the way we regulate the water industry. Backed by significant investment we are delivering increased scrutiny and oversight through a specialised workforce dedicated to each water and sewerage company.   We recognise that further change is needed and that improvements …

A complex picture, but a clearer path: what the 2025 water classifications tell us about England’s waterways

Sampling water for quality check

Each time we publish the latest assessment of England's waters through the Water Environment (Water Framework Directive) Regulation classification, a familiar headline emerges: only a minority of rivers, lakes and estuaries achieve "good" overall status. It's a figure that invites a simple reading: that progress is “too slow”, that investment “hasn't delivered”, that the water environment is stagnating or declining. Those concerns are understandable, but they …

This research is another important contribution to our understanding of Windermere, giving us and our partners greater insight to inform decisions about managing nutrient pollution as the climate changes. The modelling approach can also be applied to other lakes facing similar pressures, helping identify which interventions will work best and where. 

Launching BluePrint: Expanding citizen science across England's waterways 

A river surrounded by lush vegetation.

We’re delighted to announce the launch of a new digital tool that lets you report on the health of your local rivers, lakes and beaches in real-time, directly from your phone.  BluePrint, developed by the Environment Agency in partnership with Hello Lamp Post, builds on the success of WaterWatch - a year-long pilot that gathered public observations at five bathing water sites. Now, the concept is going national.

Our teams have been busy monitoring 66 sites across Windermere and its tributaries throughout 2025. Our live monitoring equipment is deployed in seven locations and each deployment gives us countless data points about oxygen levels, temperature and other important factors that tell us how healthy the lake is.

Today marks a significant moment for all of us who care about England’s rivers and streams. Today, we’re releasing our first set of analysis-ready water data under Defra’s Natural Capital and Ecosystem Assessment (NCEA) programme and I’m immensely proud of the work of hundreds of committed Environment Agency Staff that has got us to this point.
