Trace and Access Insurance Claims: What London Homeowners Need to Know

What Is Trace and Access Cover?

Trace and access is a specific provision found in most standard home buildings insurance policies in the UK. It covers the cost of locating (tracing) and physically accessing a hidden or concealed water leak — but not the repair of the pipe itself, and not the redecoration or reinstatement of the access point once the repair has been completed.

The practical meaning of this is important to understand before you make a claim. If a hidden leak in a first-floor pipe has been seeping into the floor void for weeks, your insurer will typically pay for a leak detection survey, the cost of lifting floorboards or breaking through a tile floor to reach the pipe, and the labour involved in opening up the access. What is explicitly excluded from trace and access cover in almost all policies is the repair itself — the cost of replacing or fixing the leaking pipe — and the redecoration that follows. Your plumber can do the repair but you are paying for that yourself.

The purpose of this split is understandable from an insurer's perspective: the repair itself is a maintenance issue that lies within the property owner's responsibility; the damage caused by a hidden leak that could not reasonably have been detected is what the insurance covers.

What Is Covered Under Trace and Access

In a standard UK buildings insurance policy with trace and access included, the following costs are typically covered:

• Professional leak detection: The cost of a qualified leak detection specialist using acoustic listening equipment, thermal imaging, tracer gas, or moisture mapping to identify the precise location of the hidden leak.
• Access work: Breaking through walls, lifting or breaking floors, removing tiles, cutting through ceiling plasterboard, removing kitchen or bathroom cabinetry — whatever physical access is necessary to expose the leaking pipe.
• Labour for access: The time and skill involved in the access work itself, including any specialist trades needed (for example, a tiler to lift a tiled floor or a plasterer to open a wall).

The cover limit varies by policy. Many standard policies offer £5,000–£10,000 of trace and access cover. Premium policies may offer more. Check your schedule of cover for your specific limit before instructing any work.

What Is NOT Covered

Equally important — and frequently misunderstood by homeowners — are the exclusions:

• The pipe repair itself: Fixing or replacing the leaking pipe is not covered under trace and access. The plumber's cost for the actual repair comes from your own funds, or potentially from escape of water cover under a different section of the same policy if the repair relates to water damage rather than pipe maintenance.
• Redecoration: The cost of retiling the bathroom floor that was broken up to reach the pipe, replastering the wall, or reinstating the kitchen cabinets that had to be removed is generally not covered under trace and access. Some policies include a separate reinstatement provision — check yours carefully.
• Garden or external work: Leaks in underground external pipes or service connections often fall outside the standard trace and access provision. External leak detection may still be claimable but confirm with your insurer before instructing work.
• Pre-existing damage: If the leak has been present for a long time and was or should have been apparent to the homeowner, insurers may decline the claim on the basis of gradual deterioration or failure to maintain — check your policy's language on this point.

Excess Amounts

Your policy will have a standard excess applied to trace and access claims — typically the same as your general buildings insurance excess, often £100–£500. Some policies apply a higher specific excess to escape of water or trace and access claims. Confirm the applicable excess before instructing work, so you can make an informed decision about whether the claim is worth making for a small detection job.

How to Make a Claim: Step by Step

The sequence matters. Taking the wrong steps before contacting your insurer can undermine your claim or mean that work is not covered.

1. Contact your insurer before any work begins. This is the most important step. Call your insurer's claims line as soon as you suspect a hidden leak. Do not instruct a leak detection company or start any access work without prior insurer approval. Insurers are entitled to decline coverage for work they were not given the opportunity to authorise.
2. Request written approval. Ask your insurer to confirm in writing (email is sufficient) that the trace and access work is covered under your policy and that you are authorised to proceed. Note the claim reference number.
3. Ask whether your insurer has preferred contractors. Some insurers have approved supplier networks and require you to use them. Others allow you to choose your own contractor. Confirm this before booking an independent leak detection company.
4. Use an accredited leak detection company. For the claim to be processed smoothly, use a company whose engineers can produce a professionally documented detection report. Credibility matters with insurers — an engineer with relevant accreditation (BPEC, Gas Safe where applicable, RICS-affiliated for property surveys) and professional indemnity insurance produces reports that loss adjusters take seriously.
5. Keep all invoices and reports. Retain every document: the leak detection report identifying the leak location and cause, the access quotation, the access invoice, photographic evidence of the leak and the access work, and any communications with your insurer.

Our Role in the Trace and Access Process

When we attend a trace and access insurance claim, our engineers provide a structured process designed to support the claim as well as to find the leak:

• Pre-access detection report: A written report confirming the leak location, the detection method used, and the minimum access required to reach the pipe. This report is submitted to the insurer before access work begins, allowing the loss adjuster to authorise the scope.
• Photographic documentation: Photographs taken at every stage — before access, during access, and of the exposed leak — create a visual record that supports the claim and prevents any dispute about what access was necessary.
• Loss adjuster liaison: For larger claims, the insurer may appoint a loss adjuster to attend the property and assess the claim scope. We are experienced in working directly with loss adjusters, providing the technical detail they need and answering questions about why specific access was required.
• Scope management: We access to the minimum extent necessary to expose the leak — not more. Over-enthusiastic access work that exceeds the necessary scope creates unnecessary cost and may result in insurers declining part of the claim as disproportionate.

Tips for Maximising Your Claim

Several practical steps can improve the outcome of a trace and access claim:

• Document the problem thoroughly before calling. Photograph damp patches, water stains, and any evidence of the leak. Note when you first noticed the problem. This establishes the timeline and helps your insurer assess whether it was a sudden event or gradual deterioration.
• Check your policy limits before instructing expensive detection. Some trace and access limits are surprisingly low — if your limit is £2,000 and you are considering a complex thermal imaging survey of a large property, understand the arithmetic before proceeding.
• Request an itemised detection quote. A clearly itemised quote (detection fee, access labour, materials, per-hour rates) is easier for a loss adjuster to approve than a single lump-sum figure.
• Do not start remediation work until the claim scope is agreed. If the insurer wants to send a loss adjuster, wait until they have attended before any reinstatement work begins.

Documentation Needed for a Claim

A complete trace and access claim file should contain:

• Your insurance policy schedule (confirming trace and access cover and the applicable limit)
• The claim reference number issued by your insurer
• The leak detection report from the attending engineer
• Photographic evidence of the leak and all access work
• Invoices for detection and access work
• Any correspondence with your insurer or loss adjuster
• Receipts for any emergency containment measures (towels, buckets, dehumidifiers)
