A Step-by-Step Guide to Your Trace and Access Insurance Claim

Trace and access claims fail more often on sequence than on cover. The policy responds; the claim still gets trimmed, because a floor came up before anyone surveyed, or the insurer heard about the leak a fortnight after it was found, or one invoice arrived covering four different things. This guide sets out the order the work has to run in, and what has to exist in writing at the end of each stage.

Step One: The First Hour, Before You Call Anyone

What happens in the first hour has more effect on the claim than anything that happens in the first week. Three things need doing, in this order.

Stop the water, then make it electrically safe

Stop the water. Close the internal stop tap, and if the leak is on a heating circuit, isolate the boiler and close the radiator valves either side of the suspected area. If the stop tap will not turn, that is now the emergency, and an emergency plumber is the right call rather than a leak detection specialist.

Make it safe. Water and electricity share voids in almost every UK property. If water is running through a ceiling containing light fittings or reaching sockets, switch off the affected circuits at the consumer unit before anyone walks underneath.

Photograph before you mitigate

Photograph everything before a single towel is moved. These images are the only record of the damage in its original state and they cannot be recreated later. Capture:

• Wide shots that establish which room and which surfaces are affected.
• Close shots of staining and its edges, which show how far water has travelled.
• The ceiling from below and the floor from above, including any sagging or blistering.
• Standing water, affected contents and anything you are about to move.
• The water meter or the boiler pressure gauge where either is relevant to the cause.

Then write down the date and time you first noticed the problem rather than trusting it to memory. That single note does more work later than any photograph, because it is the fact the gradual damage question turns on.

Step Two: Notify the Insurer

Policies require notification as soon as reasonably possible, and delay is the easiest thing for an insurer to criticise. Notify before you have quotes, before you know the cause, and before you know the extent. A first notification is not a claim; it is a date stamp.

Have ready the policy number, the date and time you noticed the problem, what you have already done to stop or limit it, and whether the property is habitable. Then ask four questions in return and write the answers down:

• What is the escape of water excess on this policy?
• What is the trace and access limit, and is it on the schedule or the booklet?
• Must I use an approved contractor, or may I appoint my own?
• What written authority will you issue before investigation work starts?

The third question matters more than it sounds, because instructing the wrong party can put the whole cost outside the claim even where the leak is plainly covered.

If the property is a leasehold flat, establish immediately whose policy applies. Buildings cover for a block is normally held by the freeholder or managing agent, and a leaseholder who notifies only their own contents insurer has not started the claim that matters.

Step Three: Get Authority Before Anything Is Opened

This is the step most often skipped and the one that most often costs money. Investigation work should be authorised before it starts, in writing, with the scope described. What authority looks like varies: a claim reference and an instruction to proceed, a stated cash limit, or an appointment of a named contractor.

There is a narrow exception. Where water is actively escaping and cannot be isolated, mitigating the loss comes first, and a policyholder who acts sensibly in an emergency is generally not penalised for it. That exception covers stopping the water. It does not cover lifting a floor on a hunch three days later.

Get the scope stated as one of three things, because the distinction drives the invoice: detection only, detection plus controlled opening-up, or detection through to repair and reinstatement. Our guide for loss adjusters and insurers sets out what each of those scopes contains.

If the insurer insists on its own contractor and that contractor cannot attend for several days while the property is uninhabitable or water is still present, say so in writing and ask for the delay to be recorded. An insurer that cannot supply a contractor within a reasonable period is in a weak position to criticise a policyholder who appoints one, provided the policyholder asked first and kept the correspondence.

Step Four: The Non-Invasive Survey

What happens on site

A survey starts with elimination rather than with equipment. The engineer establishes which systems are present and which could physically produce the observed damage, then works through them. Moisture mapping across the affected fabric shows the distribution and usually the direction of travel. Acoustic equipment is used on pressurised supply pipework. Thermal imaging is used where a heating circuit is suspected. Isolated sections are pressure tested and the parameters recorded. Tracer gas is introduced where nothing else reaches, typically on underfloor heating or low-pressure runs.

What should not happen

Nothing should be opened up until the non-invasive work is exhausted and a defined target area exists. Opening up early destroys the moisture distribution that demonstrates where water travelled from, and that evidence is what answers the insurer's question about whether the damage was sudden or gradual. It also creates search damage that was never authorised against any target. If a contractor proposes lifting a floor before surveying it, ask what has been ruled out and how. A survey that has ruled nothing out is not a survey. Our emergency leak detection page describes what a first attendance covers.

What a survey cannot settle

It is worth knowing the limits before the report arrives. A survey establishes where water is and where it came from. It can often indicate whether a failure is recent or long-standing from corrosion, scale and the condition of surrounding fabric, but it cannot date a leak precisely, and a report claiming otherwise is overstating itself. It also cannot resolve questions of liability between neighbours or between leaseholder and freeholder, which are legal questions the evidence feeds into rather than answers.

Step Five: The Evidence the Insurer Will Ask For

Different items are produced by different people at different moments, and almost none of them can be produced retrospectively. This is what a complete file looks like.

Step Six: Opening Up and Making Good

Controlled access means a defined area, agreed in advance, recorded before and after. In practice that is a stated floor area lifted, an aperture of known dimensions cut, or a specific panel or run of boxing removed. Anything wider needs a reason recorded in the report.

Two pitfalls here. The first is scope creep, where the opened area grows during the day and nobody updates the authority. The second is duplication with drying, where flooring has already been lifted for airflow and the same work then appears again on a detection invoice. Check what has already been opened before agreeing a scope.

In a flat, add a third pitfall: access through somebody else's demise. Where the source is in the property above, the opening-up happens in their home, under their lease and potentially on the block policy rather than yours. Agreement between the two leaseholders, the managing agent and the block insurer has to be in place before an engineer attends, and arranging that is usually the slowest part of the whole claim.

Making good the search damage means returning the opened area to its previous condition. It does not extend to redecorating an entire room so that the repair is invisible, and it does not include the water damage. Those sit under the main escape of water cover, with the escape of water excess applied. The distinction is set out in full in our trace and access cover guide.

Step Seven: The Repair, Then the Reinstatement

With the failure exposed, the repair itself is usually straightforward and usually outside the claim. Most published wordings treat a component that has simply failed or worn out as a maintenance cost, so budget for it separately and insist it is invoiced separately.

Reinstatement of the water damage follows drying rather than preceding it. Plastering, flooring and decoration applied over a structure that has not reached target moisture content will fail, and a second claim for the same damage is a difficult conversation. If a drying contractor is engaged, let them confirm target readings in writing before reinstatement is booked.

Some insurers will offer a cash settlement instead of managing the reinstatement, which can suit a policyholder who wants control over finishes and timing. Before accepting, check that the figure covers the full scope including drying, that it is not net of a trace and access limit that has already been consumed, and that accepting it does not close the claim while damage remains hidden under a floor. Once a claim is settled and closed, reopening it for something discovered later is much harder than adding to a live one.

Keep the four costs on four lines throughout: detection, access and making good, repair of the component, and reinstatement of the water damage. A single combined invoice invites the insurer to apply the trace and access limit to the whole figure.

Step Eight: If the Claim Is Declined or Reduced

A declinature is a position, not a conclusion. Ask for it in writing with the specific policy term relied on quoted in full, because a decline letter that gestures at wear and tear without citing a clause is hard to challenge and easy to withdraw.

The three arguments worth making

Three points are worth raising where they apply. ICOBS 8.1.1R in the Financial Conduct Authority's Handbook requires an insurer to handle claims promptly and fairly, to provide reasonable guidance and information on progress, not to unreasonably reject a claim, and to settle promptly once terms are agreed. Section 11 of the Insurance Act 2015 prevents reliance on a breach of a term where the policyholder shows the breach could not have increased the risk of the loss that actually happened. And the Financial Ombudsman Service publishes guidance on gradual damage 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.

Escalating to the ombudsman

Exhaust the insurer's own complaints procedure first, then refer to the Financial Ombudsman Service, which publishes its decisions in a searchable database. Reading two or three decisions on comparable facts is the cheapest preparation available, and a detection report that already engages with the concealment and timing questions will do most of the work for you.
