Trace and Access Insurance Cover Explained: Limits, Exclusions and Refusals

Trace and access is one of the few insurance terms most policyholders meet only once, at the worst possible moment, and usually in a sentence beginning with the words unfortunately your policy. It is the clause that pays for finding a concealed leak and for repairing the damage caused by looking for it. It is not the clause that pays for the leak, and it is not the clause that pays for the water damage, and almost every dispute about it starts with those two confusions.

What Is Trace and Access Cover?

Trace and access is an extension attached to the escape of water peril on a buildings policy. It responds to two costs that would otherwise sit with the policyholder: the cost of locating a leak that cannot be seen, and the cost of putting back whatever had to be removed to reach it.

The reason it exists is structural. A domestic water leak inside a building almost never presents where it originates. Water leaves a pipe under a screed, tracks along the line of least resistance, and appears on a ceiling two rooms away. Without this clause, a policyholder facing a covered escape of water would still have to pay to find it, and the amount they would pay depends entirely on how inaccessible the building happens to be. Insurers added the extension because the alternative was settling the damage while leaving the cause in place.

The phrase itself splits neatly. Trace is the investigation: acoustic survey, thermal imaging, moisture mapping, pressure testing, tracer gas. Access is the physical opening-up that follows: lifting a defined area of floor, cutting an aperture in a ceiling, removing a bath panel or a run of boxing, and then making that good again.

Because it is an extension rather than a standalone cover, it inherits every condition attached to the peril it hangs from. If escape of water does not respond, trace and access does not either, however much investigation has already been paid for. That dependency is the single most useful thing to understand about the clause, and it explains most of the refusals described further down this page.

Is Trace and Access Standard on UK Home Insurance?

It is close to universal on buildings cover, but the terms on which it is granted vary enormously, and published wordings do not agree on the most basic questions. The table below compares three UK home insurance documents as published.

Three insurers, three materially different answers, on a clause most comparison articles describe as if it were standardised. Two consequences follow. Never assume a market average applies to your policy, and read the schedule rather than the marketing page, because the monetary limit is frequently on the schedule even where the booklet describes the cover in words.

Leasehold flats add a further complication. The buildings policy for a block is normally arranged by the freeholder or the managing agent, so the trace and access clause that matters is the one on the block policy rather than on any policy the leaseholder holds personally. A leaseholder whose ceiling has been damaged by a leak from above may therefore be relying on a document they have never seen, held by a party they have no direct relationship with. Asking the managing agent for the relevant extract early is worth the awkwardness, because the limit determines what can be instructed.

What Does Trace and Access Cover?

The investigation

Non-invasive detection work is the core of it: acoustic listening and correlation on pressurised supply pipework, thermal imaging on heating circuits, moisture mapping across affected fabric, pressure testing of isolated sections, and tracer gas where nothing else will reach. A negative result is part of the work, because eliminating a system is how a survey narrows to a source. Insurers generally accept this, provided the report records what each method ruled out rather than listing equipment for its own sake.

The opening-up and the making good

Once the source is located to a defined area, access is the controlled removal of whatever sits between the surveyor and the pipe: a section of floor covering and boards, a cut in plasterboard, tiling around a concealed joint, a bath panel, kitchen plinths, a run of boxing. Making good means returning that area to its previous condition. Note the limit of that promise. Making good the search damage is not the same as redecorating the room, and it is not reinstatement of the water damage, which sits under the main escape of water cover with its own excess.

What Does Trace and Access Not Cover?

This is the section most guides skip, and it is where refusals come from. In most published wordings the clause does not pay for:

• Repair of the pipe, joint, tank or appliance that failed, where the failure was wear and tear. Aviva states this in terms; esure is the exception among the three compared above.
• Damage caused by water entering from outside the building, because trace and access is attached to escape of water, not to storm, flood or roof defects.
• Investigation of a leak the policyholder already located, where no searching was required.
• Work carried out before the insurer authorised it, unless the situation was genuinely an emergency and the decision can be justified.
• Reinstatement of the water damage itself, which is a separate head of claim against a separate part of the policy.
• Investigation at a property that has been unoccupied beyond the period stated in the policy, because the underlying peril has already fallen away.
• Anything above the stated limit, which is reached faster than most policyholders expect where floors have to come up.

There is a further boundary that catches people out in bathrooms. Where water escaped past failed or missing sealant or grout rather than out of the plumbing system, the escape of water peril does not respond at all, and trace and access falls with it. Our guide to escape of water claims sets out the exclusions in detail.

It is also worth knowing how quickly a stated limit is consumed. The cost is driven by construction rather than by the size of the leak. A pipe under a suspended timber floor with accessible boards is a straightforward exercise. The same failure under a bonded screed with tiled finishes, or beneath an engineered floor laid over insulation, involves cutting, disposal, screed reinstatement, drying time and relaying, and the search damage alone can approach a mid-range limit before anybody has looked at the water damage. That is why the scope should be agreed against the limit at the outset rather than discovered halfway through.

Trace and Access, Escape of Water, the Repair and the Damage

Four different costs arise from one leak, and they are paid, or not paid, by four different mechanisms. Keeping them separate on the invoice is what allows a claim to be settled without argument.

If a contractor issues a single invoice combining all four, the insurer will either query it or apply the trace and access limit to the whole figure, and the policyholder loses either way. The repair work belongs on its own line, every time.

What Belongs in a Trace and Access Report?

The report is the product. A located leak with no written record behind it is very hard to recover against a clause that pays for reasonable costs, because reasonableness has to be demonstrated. A report that supports a claim carries:

• The instructing party, the claim reference, and the dates of instruction, attendance and issue.
• A description of the property, its construction and floor build-up, and the systems present.
• The methods applied in the order applied, with what each one ruled in or out.
• Moisture readings with the instrument stated, distinguishing indicative from quantitative readings.
• Pressure test parameters: pressure applied, duration held, drop observed.
• Photographs of the source, the surrounding fabric and any area opened, taken before and after.
• The failed component named, with its mode of failure and a view on whether the evidence indicates a sudden failure or a longer-standing defect.
• A scope of works separating repair, reinstatement of the search damage, and anything outside scope.

That structure is not decorative. It is what allows a claims handler who has never seen the property to authorise the cost without a site visit. Our specification for loss adjusters and insurers sets out the same document from the instructing side.

Why a Trace and Access Claim Gets Refused

Process reasons

Work carried out before authority was given is the commonest. So is a floor lifted speculatively before any survey, which converts a recoverable search into unauthorised damage and simultaneously destroys the moisture evidence that would have justified it. Invoices that bundle the repair into the search are refused or trimmed. So are reports that describe an outcome without recording a method.

Cover reasons

If the underlying peril fails, the extension fails with it. That happens where the water came from outside the building, where the source was failed sealant or grout, where the property was unoccupied beyond the stated period, or where the insurer relies on a gradually occurring damage exclusion. On that last point the Financial Ombudsman Service publishes guidance indicating it will normally require payment where the damage was caused by an insured event, the policyholder could not reasonably have known it was happening gradually because it was concealed, and they acted as soon as they reasonably could. Concealment and timing are evidential, which is another reason the survey happens before the crowbar.

Are Underground Pipes Covered?

Underground supply and drainage pipes are treated separately in most wordings and often carry their own section and their own limit, so the answer is frequently yes but not under this clause. Two points from the Financial Ombudsman Service's guidance on damage to underground pipes are worth knowing. Damage is not limited to physical damage and extends to loss of function, so a pipe that is structurally intact but no longer working can still found a claim. And an insurer may need to put right damage caused while investigating, including excavation, even where the claim is ultimately declined.

Practically, this means an underground investigation should be scoped and authorised in its own right, with the making-good position agreed before anyone digs. Where the loss is inside the building line, a trace and access survey is the right instruction, and the sequence of what to do and when is set out in our step by step claim guide.
