How to Check if Your Water Leak Is Covered by Your Water Company or Your Responsibility

Discovering a water leak can be stressful — especially when you’re unsure who is responsible for fixing it. One of the most common questions we’re asked at Cascade Water Services is:

“Is this leak my water company’s problem, or do I have to deal with it myself?”

In this guide, we’ll explain how responsibility for water leaks is decided in the UK, how to check where the problem lies, and what to do next.

Understanding Water Pipe Responsibility in the UK

In most cases, responsibility for a water leak depends on where the leak is located.

3. Locate the External Stop Tap / Meter

If you’re unsure, professional pipe tracing or leak detection can confirm it quickly.
