Check if you have a water leak

Answer a few quick questions and this tool will give you an honest indication of how likely a hidden leak is, and what it could be costing you. It takes about a minute, and you do not need any tools to start.

A single dripping tap can waste over 5,000 litres of water a year, and a hidden pipe leak can quietly add hundreds of pounds to a metered bill before anything visible appears.

First, who supplies your water?

We use your supplier's approximate metered rate to estimate what a leak costs. Most homes in Cornwall and Devon are supplied by South West Water.

Estimate your leak rate

If you can measure it, brilliant. If not, pick the scenario that sounds closest, or leave both blank and we will assume a small leak.

How to measure: for a dripping tap, count the drips in one minute and multiply by 0.07 to get litres per hour. For a suspected hidden leak, note your meter reading, use no water for one hour, then read it again: the difference in cubic metres multiplied by 1,000 is your litres per hour. For a toilet, a few drops of food colouring in the cistern will show in the bowl without flushing if it leaks.

The table only shows the water. The bigger cost of a hidden leak is what the water does while it stays hidden.

What a leak does beyond the bill

  • It soaks the building. Water tracks along joists, under floors and through walls, so damage spreads well beyond the leak point. The making-good after a long-running leak usually costs more than the water ever did.
  • Damp and mould follow. A warm, steadily fed damp patch is exactly what mould needs, and it does not wait for you to find the source.
  • Escape of water is one of the costliest home insurance claims there is. The Association of British Insurers puts insurer payouts for it at around £1.8 million a day, which is also why many policies carry a higher excess for it.
  • Waiting weakens a claim. Insurers cover sudden escapes of water, not gradual deterioration; the longer a known problem is left, the harder the conversation. Acting quickly, with a professional report, keeps you on the right side of that line. The finding itself is usually covered: see our guide to trace and access cover.
  • Found early, most leaks are a small job. One neat access point and a minor repair. Found late, they are floors up and weeks of drying. Speed is the whole game.
