What drives leak detection pricing

The price depends on how hard the leak is to find. A leak under a solid floor takes longer than one near a visible pipe. The size of the property and the methods needed matter too.

We cannot give a fixed figure, because each job differs. Ask for a written quote. Our page on leak detection in London shows one local service.

What’s included in a leak detection survey

A survey usually starts with a talk about the signs you have seen. The specialist then checks the meter and tests the pipes. They use tools such as listening devices or thermal cameras.

Afterwards you should receive a report of what they found and where. Ask whether repair is part of the price, because it often is not.

What drives the cost

Access is a big factor, since hidden pipes take longer to reach. Complex layouts add time. Several leaks cost more than one.

The method matters too. Tracer gas takes more steps than listening. Ask which methods the quote covers.

The cost of not finding the leak

A hidden leak can raise your water bill and damage the structure. It may cause damp, mould and rot. Repairs can then cost far more than the survey.

Some water companies may help with leaks on the supply pipe. Ask yours, because policies vary. Act early, since leaks do not fix themselves.

When to call a leak detection specialist vs a plumber

Call a plumber if you can see the leak or know where it is. Call a specialist if you cannot find it. The specialist finds the spot, while the plumber repairs it.

Some firms do both. Ask who will fix the leak once it is found, so you know the full job.

Book the survey as soon as you suspect a leak. Early action limits damage, because water spreads through walls and floors. Keep a note of your meter readings, since they help the specialist narrow the search.

Insurance and leak detection

Some home insurance policies pay for finding a leak. Others only pay for the damage it causes. Check your policy, because terms differ.

Ask your insurer before you book. Keep the report and invoice, since they help with a claim.
