A hidden leak can create more than one insurance question. Before anyone can repair the source, somebody may need to locate it, open a wall or floor to reach it and then reinstate the parts of the building disturbed during that investigation. That is where trace and access cover may become important.

Problems often start when every cost is treated as though it belongs to the same part of the policy. A policyholder may be told that a worn pipe is not covered and assume that the cost of finding it, reaching it and repairing the water damage must therefore also be excluded. That does not necessarily follow.

What does trace and access insurance cover?

Trace and access generally refers to the reasonable cost of locating the source of an escape of water and gaining access to it. Depending on the policy wording, cover may also include making good the parts of the building that had to be opened, removed or disturbed during the search.

A typical example is water appearing through a kitchen ceiling while the source is hidden beneath the bathroom floor above. Finding the leak might involve specialist detection, lifting flooring, removing tiles or opening plasterboard before the leaking pipe or fitting can be reached.

The precise trigger and limit vary between policies. Check the schedule, endorsements, buildings section, escape-of-water wording and any separate trace-and-access clause rather than relying on the heading alone.

Trace and access is not the same as repairing the leak

A single escape-of-water incident can contain several separate elements. Keeping them separate is one of the most useful things you can do when an insurer has refused or reduced the claim.

Worked example

A hidden bathroom leak — £6,140 of costs, but not one £6,140 coverage question

This simplified example shows why the individual parts of a trace-and-access claim should be separated before the insurer's refusal is assessed.

A homeowner notices a fresh water mark on the kitchen ceiling. A specialist traces the leak to a concealed pipe beneath the tiled bathroom floor. Part of the floor has to be opened to reach it. The failed pipe is repaired, the access area is reinstated and the damaged kitchen ceiling is dried and repaired.

Leak detection

£450

Does the trace-and-access wording cover reasonable investigation costs?

Opening the tiled floor

£1,250

Was this work reasonably necessary to gain access to the source?

Repairing the failed pipe

£240

Is repair of the defective item itself covered, or excluded?

Making good the bathroom floor

£1,900

Does the policy include reinstatement of damage caused by gaining access?

Drying and repairing the kitchen ceiling

£2,300

Is this resulting escape-of-water damage covered under the buildings section?

Suppose the insurer pays £2,300 and refuses the remaining £3,840 as “wear and tear”.

The £240 pipe repair may raise a wear-and-tear issue. But the remaining £3,600 of tracing, access and making-good costs still need to be tested against the trace-and-access wording. A single label should not replace that analysis.

Amount refused£3,840

Illustrative only: this does not mean the £3,600 must be paid. The outcome depends on the actual policy wording, what caused the leak, what damage occurred and whether the work and charges were reasonable.

Two published Ombudsman decisions show why the wording matters

Financial Ombudsman decisions are fact-specific and are not court precedents. But they are useful illustrations of how different policy wording and different facts can produce different outcomes.

Why do insurers refuse trace and access claims?

1. The policy does not include the cover claimed

The starting point is whether trace and access is included at all and what triggers it. Some policies provide a separate limit. Others place the cover within the escape-of-water section and make it dependent on particular damage or an insured event.

2. No actual leak or insured damage was established

Reasonable suspicion is not always enough. A homeowner may act sensibly by investigating an unexplained loss of pressure or moisture reading, but the policy may require an actual escape of water, physical damage or both before the trace-and-access section responds. That was central to the recent Ombudsman decision referred to above.^[3]

3. The insurer accepts there is water but disputes the cause

The argument may be about where the water came from rather than whether damage exists. Insurers may point to deterioration, failed sealant or grout, defective workmanship, gradual seepage, condensation or another cause. The stated cause should be compared with the plumber or leak-detection evidence and then with the policy wording.

4. Repair of the failed item has been confused with trace and access

A policy may distinguish between the cost of finding and reaching a leak and the cost of repairing the failed pipe itself. In DRN-4386665, for example, the wording covered reasonable tracing and access costs and repair of walls, floors or ceilings damaged during those investigations, but excluded repair of the source unless that cause was covered elsewhere. The Ombudsman then examined whether the claimed flooring work was genuinely access work or part of the repair itself.^[4]

5. The insurer says the investigation was unnecessary or too expensive

Even where cover exists, the amount claimed can be disputed. An insurer may argue that too much flooring was lifted, a cheaper technique should have been used or specialist testing was unnecessary.

The useful questions are factual: what was known at the time, where did the evidence suggest the source was, could a less destructive method realistically have located it, was urgent action needed, and were the charges reasonable for the work actually performed?

6. Work was arranged before the insurer approved it

Some policies contain notification or claims-handling requirements. Check what the policy required, when the insurer was contacted, what response was received and why immediate action was considered necessary. Where water is actively escaping, evidence of the steps taken to prevent further damage can be important.

7. The trace-and-access limit has been reached

Trace-and-access cover can have its own monetary limit. If the insurer says the limit is exhausted, ask for a breakdown showing the applicable limit, the payments allocated against it and which costs have been placed within that section.

What exactly has your insurer refused?

Before challenging the decision, separate the claim into its component parts. Ask the insurer to confirm whether it has refused:

Those are not necessarily the same coverage question. A useful refusal should identify the policy term relied upon for each material element rather than using one broad explanation for everything.

Ask for the insurer's decision in writing

If the explanation has only been given by telephone, ask for a written decision. Ideally it should explain what has been accepted, what has been declined, the wording relied upon, any expert evidence used, any trace-and-access limit and how the settlement figure was calculated.

The FCA's claims-handling rules require insurers to handle claims promptly and fairly, provide reasonable guidance and information on progress, not unreasonably reject claims and settle promptly once settlement terms are agreed.^[1]

That does not mean every refusal is incorrect. It does mean the decision should be capable of being tested against the policy, the evidence and the facts of the loss.

What evidence should you keep?

Trace-and-access disputes are usually easier to analyse when the documents show both what happened and why the work was reasonable. Keep:

• the complete policy wording, schedule and endorsements;
• the insurer's rejection, settlement or final response letter;
• plumber and leak-detection reports;
• photographs and videos before, during and after access works;
• moisture readings, thermal-imaging or other investigation results where available;
• invoices and quotations for tracing, opening up and reinstatement;
• evidence identifying the actual source once found;
• communications showing when the insurer was notified; and
• evidence explaining why urgent work was necessary.

Does “wear and tear” answer the whole claim?

Not necessarily. An insurer may conclude that a pipe failed because of age, corrosion or deterioration. That may be relevant to the defective item itself, but the policy still needs to be checked for separate cover for trace and access and for resulting escape-of-water damage.

The Financial Ombudsman has also published case studies in which gradual-damage wording was considered against the fact that a hidden leak was not reasonably apparent to the policyholder until visible damage emerged.^[5]

What if the insurer says the water came from sealant or grout?

If the evidence points to failed shower sealant or grout rather than an escape from a pipe, tank or appliance, the insurer may argue that the relevant escape-of-water wording has not been triggered or that another exclusion applies.

The response should focus on evidence rather than labels: what caused the water movement, what does the policy insure, what does the trace-and-access section require, and does the exclusion relied upon apply to the particular costs being claimed?

Do not argue about the total before identifying the disputed term

If you spent £4,800 locating a leak and reinstating the floor and the insurer offers £1,200, first establish why £3,600 has been removed. Is the difference caused by a coverage decision, a policy limit, an exclusion, a disagreement about the reasonableness of the works or a dispute about which costs count as trace and access?

Once the reason is clear, the evidence can be directed at the actual issue rather than simply presenting another total.

Can a refused trace and access claim be challenged?

Potentially. But the words “trace and access” appearing in a policy do not automatically make every investigation cost payable. A meaningful review compares the cover wording with what happened, the evidence showing how the leak was investigated and the insurer's stated reason for refusing or reducing payment.

Sometimes the insurer's interpretation will be supported by the policy. Sometimes a refusal has combined separate issues or applied wording more broadly than the documents justify. The objective is to establish which.

Frequently asked questions

Has your trace and access claim been refused?

If your insurer has refused the cost of finding a leak, substantially reduced the amount claimed or rejected the resulting water damage, do not look at the rejection sentence in isolation.

Insurance Dispute Service reviews rejected, delayed and underpaid insurance claims. We can examine the policy wording, the insurer's explanation, the leak-detection evidence and the individual elements of the claim to identify what is actually in dispute and whether there appears to be a realistic basis for taking the matter further.
