What to do if…
you notice your water meter is moving even though all taps and appliances are off

Short answer

Treat it as an active leak until proven otherwise: shut the water off at your inside stop tap (stopcock) and re-check the meter to work out whether the leak is inside your home or on the supply pipe.

Do not do these things

  • Don’t ignore it “until the next bill” — even a small continuous flow can cause damage.
  • Don’t start digging outside or lifting covers if you’re unsure what’s underneath.
  • Don’t force a stuck stop tap; forcing can snap it and make things worse.
  • Don’t assume it’s “the water company’s problem” until you’ve done the isolate test (below).
  • Don’t use any water “to test” while you’re trying to see if the meter is moving.

What to do now

  1. Make a quick safety check inside. Look for obvious signs: water pooling, damp patches, dripping noises, a toilet that’s refilling, a boiler/pipe cupboard that feels wet. If anything looks like active escaping water, keep it away from electrics and move to the shut-off step.
  2. Turn off your inside stop tap (stopcock). This is usually where the water supply enters the property (often under the kitchen sink or in a cupboard). Turn it to the off position.
  3. Check the meter again (with the inside stop tap off).
    • If the meter keeps moving: the flow is likely between the meter and your inside stop tap (often an underground supply pipe leak). Contact your water company and say: “My meter is moving with the inside stop tap off.”
    • If the meter stops: the leak is likely inside your property (after the stop tap). You’ll usually need a plumber.
  4. Document it (so you’re not relying on memory). Take a clear photo of the meter reading (and moving indicator if visible), note the time, then check again after about an hour with everything still off. If you can manage it, a longer no-use window (for example overnight) can pick up very slow leaks.
  5. If it looks like an internal leak, check the usual “silent” culprits without turning lots of things on/off:
    • Toilets first (listen for refilling; look for a constant trickle into the bowl).
    • Outside taps and any hoses/timers.
    • Appliance feeds (washing machine/dishwasher) and any obvious pipe joints you can see.
    • If you’ve just used water, wait a few minutes for any normal refilling (for example a cistern) to finish before deciding the meter is “still moving”.
  6. Decide whether to leave the water off. If you can manage without water for a while (and it’s safe for everyone in the home), leaving it off reduces damage risk until help arrives.
  7. Get the right help.
    • For leaks inside your property: contact a suitably qualified plumber (WaterSafe is one way to find an approved contractor).
    • For suspected leaks before the inside stop tap (meter still moving when it’s off): contact your water company.
    • If you rent, inform your landlord/agent immediately (and tell them what you observed with the stop tap test).

What can wait

  • You do not need to locate the exact leak point right now.
  • You do not need to decide who pays in the moment — first isolate and report.
  • You do not need to plan major pipe replacement tonight unless the water company/plumber tells you it’s urgent.

Important reassurance

This is common and usually fixable. The key is that you’ve noticed it early — isolating the supply and doing one simple test (meter + stop tap) is often enough to prevent the most expensive outcome: ongoing hidden water damage.

Scope note

This is first-step guidance to stabilise the situation and identify whether the leak is likely inside your home or on the supply pipe. Follow-up repair and responsibility can vary by property type, meter location, and your water company.

Important note

This guide is general information, not a substitute for professional assessment. If you can’t operate your stop tap safely, or you see water near electrics/ceilings/walls, treat it as urgent and get professional help.
