Leak under the floor and your insurance

Many home insurance policies include trace and access cover, which pays to find a hidden leak and open the floor to reach it. The repair to the pipe itself is usually not covered, and the water damage falls under a different part of the policy. Checking your policy before the survey avoids surprises.

What trace and access covers

Trace and access is a section of many buildings insurance policies. It usually pays the reasonable cost of:

  • Tracing the source of an escape of water, which is the leak detection survey.
  • Accessing it: lifting the floor finish, breaking the screed or concrete, or lifting boards to reach the pipe.
  • Making good the area that was opened, on some policies.

It is not included as standard on every policy, and the limit varies. Some policies only pay once damage has already happened. Your policy wording or your insurer is the only reliable answer for your home.

The three parts of a claim

A leak under a floor usually involves three separate costs, and insurers treat them differently:

How the costs of a leak under the floor are usually treated
CostUsually covered by
Finding the leak and opening the floorTrace and access cover, where the policy has it
Repairing the pipe or fittingUsually not covered by the policy; paid by the homeowner
Damage caused by the water: flooring, screed, plaster, dryingThe escape of water section of buildings and contents insurance, subject to the excess

Before you book

  • Read the trace and access section of your buildings policy, or ring the claims line and ask whether it applies and what the limit is.
  • Ask whether they want to appoint someone or are happy for you to arrange the survey. Some insurers have their own contractors.
  • Get a claim reference if you are claiming, and note the excess.
  • Take photos of the damage before anything is moved or cleaned.

The report for your insurer

After the survey ADI provides a written report of the investigation: what was tested, what each method showed, where the leak was found and what was done. You can send it to your insurer or loss adjuster to support the claim. Reviewers on Trustpilot mention reports being shared with their insurer.

The report records what the engineer found. Whether the insurer accepts a claim is their decision under your policy.

If you have no cover

Without trace and access cover you pay for the survey yourself. The office will talk you through what the survey involves before anything is booked.

Opening a floor on guesswork can miss the leak and leave more to repair. Finding the spot first keeps the opening, and the making good, as small as possible.

Examples of what a survey records

Published ADI Leak Detection jobs, with the engineer’s own photos. All case studies.

  • Grimsby, Lincolnshire. Concrete slab

    Very high moisture in the kitchen floor

    The kitchen floor was saturated. Thermal imaging marked two areas, an air test showed the pipe held nothing, and opening the utility room slab found a corroded pipe.

    Leak found under the slab; repaired in copper; re-pipe recommended

  • Burnham-on-Crouch, Essex. Underfloor heating, Screed floor

    Salts in the manifold cupboard, paving collapsing outside

    It looked like an underfloor heating leak. Isolation testing put it on the water softener bypass instead, and thermal, acoustic, tracer gas and moisture readings all pointed to one threshold.

    Leak found at the kitchen threshold; copper pipe replaced; retest clear

Will my home insurance pay?

Many home insurance policies include trace and access cover, which pays to find the leak and open the floor to reach it. It is not always included as standard, so check your policy or call your insurer before booking.

Trace and access does not normally cover the plumbing repair itself. The damage caused by the water may be covered under a separate part of the policy. Leaks and insurance.

Do I get a report for my insurer?

Yes. ADI provides a written report of the investigation, what was found and where, which you can send to your insurer or loss adjuster.

Is there a no find, no fee guarantee?

ADI’s no find, no fee terms apply to a single leak on a hot or cold water supply at one property losing at least half a litre a minute, and to water mains up to 30 metres long. They do not apply to central heating, which includes wet underfloor heating. Ask on the phone whether your job qualifies.
