Check for toilet leaks

Is your loo leaking?

A leaking toilet can waste on average 215 litres of water every day, costing you around £200 a year. If you have a water meter, we're sure you want to keep that money in your pocket. 

How do I know if it's leaking?

Here are a few things you can do to see if your toilet is leaking:

• Can you see water running constantly in the toilet? Sounds like you've got a leak.
• Can you hear the water running, even when it's not in use? Leaks aren't always visible.
• Do you have a water meter? Have you noticed your usage has gone up, but you're not sure why? You might have a leak in your system. We've got advice on what to do if you think your bill is high.
• If you're not sure if it's leaking, use your smartphone to send a video of your toilet (opens new window). We'll contact you within five working days to let you know if you have a leak.
