Trace and access claims: what is covered, and what to do if yours is refused
Trace and access is the part of your buildings insurance that pays to find a hidden water leak and open up your home to reach it, then put back what was removed. It covers the finding, not the fixing. Most UK policies include it up to a capped limit, and it is one of the lines most often missing from a settlement.
Key takeaways
- Trace and access pays to locate a leak and access it, plus reinstatement of what was removed. It does not pay to repair the failed pipe.
- The damage the water caused is a separate escape of water claim. Two things, one incident, settled differently.
- Detection typically costs £400 to £600 excluding VAT, while policy limits commonly sit between £5,000 and £10,000. Some policies cap much lower.
- The most common refusals: the water came from outside, no leak was found, or there was no resulting damage.
- Trace and access is regularly left out of a first settlement offer. Check the offer line by line before you accept it.
What is trace and access cover?
Trace and access covers two distinct costs after a hidden leak.
Trace is finding it. A leak under a solid floor or inside a wall cavity does not announce itself, so a specialist uses thermal imaging, acoustic listening equipment, tracer gas or moisture mapping to pinpoint the source without demolishing the house to look for it.
Access is getting to it. Lifting floorboards, cutting into plasterboard, taking up tiles, digging out screed. It also covers putting those things back afterwards, which is the part people forget and the part that costs the most.
The cover exists because of a gap in how home insurance works. Your policy pays for damage caused by escaping water. Without trace and access, the cost of finding that water would fall on you, and on a concealed leak that investigation can cost more than the repair.
What trace and access does not cover
This is where most disputes start, so be precise about it.
- Repairing the pipe, tank or appliance that failed.Insurers cover the consequences of the failure, not the failed part. A plumber's bill for a new section of pipe is yours.
- The water damage itself. Ruined flooring, soaked plaster, damaged contents: that is your escape of water claim, a separate part of the policy with its own settlement. Our guide to escape of water claims covers how that side is valued.
- Ongoing maintenance or wear. If the leak is the slow product of a system past its life, expect the insurer to argue gradual damage. That argument is often beatable, and our page on wear and tear refusals explains how.
The distinction that matters: trace and access is about the search, not the repair and not the damage.
How much does trace and access cost?
Two numbers matter here, and people confuse them constantly.
What the detection work costs
A specialist leak detection visit commonly runs from around £400 to £600 excluding VAT, depending on the property, the suspected location and the equipment needed. Access and reinstatement sit on top and vary enormously. Lifting and relaying a section of laminate is a different proposition from breaking out and rescreeding a kitchen floor.
Total trace and access costs on a concealed leak under a solid floor can reach several thousand pounds before anyone has repaired a single thing.
What your policy will pay
Policy limits commonly sit between £5,000 and £10,000 per claim. Some sit considerably lower, at £1,000 or £2,500, and a minority of policies exclude trace and access altogether or sell it as an optional extra.
Your limit is written in your policy schedule, not in the marketing. Find it before you authorise work, because the gap between a £2,500 cap and a £4,000 investigation is money you will be asked for personally.
Trace and access also usually sits under your escape of water excess, which on water claims is often higher than your standard excess. Check both figures together rather than separately.
Why trace and access claims get refused
Four reasons account for most refusals. Each is a position rather than a fact, and each can be tested.
The water came from outside
Trace and access applies to water escaping from something inside the building: pipes, tanks, heating systems, appliances. Rain coming through a roof, a window or a failed seal is water ingress, which sits under storm or another section of the policy entirely, and is frequently excluded from trace and access.
Insurers lean on this one hard, because on first inspection a damp ceiling looks the same either way. If the true source is an internal pipe running through a roof void, that distinction is worth arguing with evidence. See our guide to storm damage and water ingress claims for where the line falls.
No leak was found
If the specialist investigates and finds nothing, many policies decline the cost. The logic is that the cover pays to find a leak, and no leak means nothing to find.
This is harsh but common. It is also why you should never authorise investigation work without telling your insurer first: an insurer that instructed the visit is in a much weaker position to refuse the bill than one that heard about it afterwards.
There was no resulting damage
Several policies require actual damage before trace and access is triggered. A leak discovered early, with no ruined plaster or flooring, can fall outside cover on that basis.
You went ahead without telling them
The single most common own goal. A homeowner with water coming through a ceiling calls an emergency plumber, authorises detection work at nine on a Sunday evening, and submits the invoice afterwards. The insurer then says it was never given the chance to appoint its own contractor at its own rate, and declines or reduces the bill.
Emergency mitigation to stop further damage is a different matter and is generally expected of you. Investigation work is not an emergency in the same sense. Ring the insurer first, even if the answer is a claim reference and a promise to call back.
How to challenge a refused trace and access claim
A refusal is a position, and positions can be tested. Four steps, in order.
- Get the exact reason in writing. Not a phone call summary. Ask which policy term they are relying on, quoted, with the section reference. Vague refusals collapse under this question more often than you would expect, because the person declining has sometimes applied a general rule rather than read your schedule.
- Read your own schedule against it.Trace and access wording varies far more between insurers than the comparison sites suggest. Some cover "the cost of locating the source"; others add "and repairing damage caused in the course of locating it", which is materially broader. The wording you bought is the wording that governs.
- Get the evidence that speaks to their specific reason. If they say the water came from outside, you need the detection report identifying an internal pipe. If they say no damage resulted, you need photographs and moisture readings from before the repair. Match the evidence to the objection rather than sending everything you have. Our evidence checklist covers what to gather.
- Complain formally, then escalate. The insurer has up to eight weeks to give a final response. After that, or if the eight weeks pass in silence, you can refer it free to the Financial Ombudsman Service, which can look at the case afresh and direct the insurer to put it right. You usually have six months from the final response to do this, and that deadline catches people out.

The line most often missing from a settlement
Refusal is the loud problem. Omission is the quiet one, and it costs more people more money.
A settlement offer arrives covering the visible damage: the flooring, the plaster, the decorating. It looks reasonable, because it addresses everything you can see. It says nothing about the £2,800 you spent finding the leak, because nobody put that line in the schedule of works.
Insurers do not always do this deliberately. A loss adjuster scoping a job works from what is in front of them, and the detection invoice frequently sits in a different email thread from the damage assessment. That does not make it your loss to absorb.
Before accepting any escape of water settlement, check it contains four things:
- Trace and access, including reinstatement of anything opened up.
- Alternative accommodation, if you had to leave.
- Contents, not only buildings.
- Drying and strip out, which on a serious leak runs for weeks.
Our page on underpaid water damage claims goes through the full checklist and how to reopen a settlement you have already been offered.

Is trace and access cover worth having?
For most homeowners, yes, and the reasoning is about probability rather than price.
Escape of water is among the most frequent home insurance claims in the UK. The Association of British Insurers reports that insurers pay out around £1.8 million every day for it. A meaningful share of those claims involve a leak nobody could see, and on those the detection and reinstatement bill routinely exceeds a thousand pounds.
What to check when comparing policies:
- Is it included or an optional extra? Both exist.
- What is the limit? A policy with a £1,000 cap on a topic where costs reach £5,000 is thinner than it looks.
- Does the wording cover reinstatement? Finding the leak is cheap next to putting the floor back.
- What excess applies? Escape of water excesses are typically higher than standard.
The headline premium is a poor guide to any of this. The schedule is where the answer lives. If the claim is a large one, our page on high-value water damage claims explains where independent help pays for itself.
What to do next
Trace and access is a small clause with a large price tag attached, and it fails claimants in two directions: refused when it should be paid, or quietly left out of a settlement nobody reads closely. Three things worth doing today:
- Find your limit. Open the policy schedule and locate the trace and access figure and the escape of water excess. Do it before you need them.
- Notify before you authorise. One phone call is the difference between a covered investigation and a personal bill.
- Check any offer line by line. If trace and access is absent from a settlement following a hidden leak, the offer is incomplete rather than final.
If your claim has been refused, or an offer has landed that looks light, we can tell you whether it stands up. Every enquiry starts with a free, no-obligation claim review, and for larger or contested claims we can introduce you to an independent loss assessor, a professional who works for you rather than the insurer. Our guide on whether you need a loss assessor is honest about when you do not.
