Meeting to be held over sewage pollution concerns in Windermere

Residents and businesses are invited to attend to meet specialist environmental lawyers and to share how they have been impacted by sewage pollution.

The meeting will be hosted by law firm Leigh Day, which is investigating potential for a group legal action over sewage pollution in England’s largest lake.

Sewage is understood to be the biggest source of phosphorus pollution in Windermere, which can lead to environmentally damaging algal blooms and the growth of harmful blue-green algae.

The sewerage system in the area is managed by United Utilities, which recorded eight days of continuous sewage discharge in September 2025.

The meeting hosted by Leigh Day will invite residents and business to share their experiences of sewage pollution in Windermere, and how they feel they have been impacted.

Lawyers will explain how court action is a route to tackling pollution by focusing alleged polluters’ attention on action and remediation.

The event will take place at the Marchesi Centre in Windermere. Anyone interested in attending can register via this link or just attend on the day.

Leigh Day is currently bringing the biggest UK environment legal action on behalf of around 4,500 residents and businesses affected by pollution in the Wye catchment.

It is also running group environmental actions tackling water pollution in Exmouth, and has extensive experience in bringing environmental and group claims.

Leigh Day partner Sarah Moore, who is leading Leigh Day’s investigations, said:

“We are currently investigating legal action over sewage pollution in Windermere. This meeting is an important opportunity for us to not only introduce ourselves to the local community, but to understand how sewage pollution might be impacting residents and businesses directly. We hope to speak to and hear from as many people as possible, so that we can better understand what residents are feeling about the situation.”
