Insurance Cover for Damp: What Is and Isn’t Claimable

Leaking pipe beside fresh damp damage

Most UK home insurance does not pay to cure damp itself. It may pay for damage when the damp comes from a sudden insured event, such as a burst pipe, a storm or a flood. Rising damp, condensation and slow leaks are normally excluded. Which side of that line your problem falls on depends on the cause, and the cause has to be shown with evidence.

This guide explains where the line sits, what to document before you contact your insurer, and what to do if a claim is refused.

TL;DR

Standard buildings and contents policies usually exclude damp that develops gradually: rising damp, condensation, blocked gutters and long-term leaks.
Damp and mould that result from a sudden insured event, such as a burst pipe or flood, may be covered. Policies differ, so read your own wording.
Do not repair or strip out before the insurer has had the chance to inspect. Photograph everything and keep receipts.
If a claim is declined, you can complain to the insurer and then to the Financial Ombudsman Service.
A documented, survey-led diagnosis of the cause is the strongest evidence you can have, whichever way the claim goes.

Does home insurance cover damp?

Usually not the damp itself. Howden Insurance says most policies do not pay to repair the source of damp, but may cover damage caused by it. Mould that appears after a burst pipe or sudden leak might be covered, depending on the circumstances.

MoneySuperMarket gives the same picture. Standard cover does not normally pay for damp, rising damp or mould treatment, because insurers treat these as disrepair, maintenance or gradual deterioration. Cover may apply when the damage follows an insured event such as flooding or a burst pipe.

The principle behind this is simple. The ABI says home insurance usually excludes general wear and tear and damage caused by lack of maintenance. Insurance covers sudden, accidental events. It is not a maintenance plan.

The ABI also says exclusions vary between policies and advises reading the terms to see what is and isn’t covered. Treat everything below as the general pattern, then check your own policy document.

Why the cause of the damp decides the claim

Insurers do not ask “is there damp?” They ask “what caused it, and how quickly?” The same wet patch on a wall can be a covered claim or an excluded one.

Cause	Usually treated as	Likely outcome
Rising damp through a failed or missing damp-proof course	Gradual deterioration or maintenance	Excluded in most standard policies
Condensation and black mould from poor ventilation	Gradual, lifestyle or maintenance related	Excluded
Blocked gutter or defective pointing letting rain in over time	Maintenance	Excluded
Slow, long-running leak that went unnoticed	Gradually operating cause	Often excluded
Burst pipe or sudden escape of water	Insured event	May be covered, subject to terms
Storm damage to the roof, or flooding	Insured event	May be covered, subject to terms

Lemonade UK draws the same distinction. A sudden escape of water can trigger buildings cover for structural damage and contents cover for affected belongings, but mould remediation itself is not ordinarily a covered contents cost.

The ABI’s guide to buildings and contents insurance says most policies cover loss or damage from water leaking from tanks or pipes, and that storm and flood are among the risks most policies cover. Coverage varies between policies.

Sudden versus gradual: the wording to look for

In your policy documents, look for phrases such as “gradually operating cause”, “wear and tear”, “deterioration”, “maintenance” and “faulty workmanship”. The ABI lists general wear and tear, maintenance, faulty workmanship and mechanical or electrical breakdown among common exclusions.

The Financial Ombudsman Service explains that gradual damage is a common policy exclusion, and that some insurers specifically exclude rot, which usually develops slowly. That matters if your damp has led to timber decay.

Empty homes and long absences

Policies may restrict cover when a property is empty for a long time. The ABI gives the example of water-leak damage being excluded if the home is unoccupied for 30 days in a row. Landlords with void periods and owners of second homes should check this clause.

Some insurers do offer specific cover

The AA says most buildings and contents policies will not cover damage caused by damp and condensation, though some insurers offer specific cover for rising damp. That is an optional extra at best, and it is not the norm.

Two other things are worth knowing:

Damp guarantees are not insurance. A written guarantee from a damp specialist covers the workmanship and the treatment they carried out. It does not pay out for a new problem elsewhere in the building.
Home emergency cover is a different product. The ABI describes it as an optional extension that pays for a tradesperson to deal with an emergency. It is aimed at urgent call-outs, not at curing long-term damp.

Buildings or contents: who is covered for what

Buildings insurance covers the structure: walls, roof, floors, plaster, fixed pipework. Contents insurance covers your belongings. If a burst pipe ruins a carpet and a sofa, those fall under contents. The damaged plaster and the pipe repair fall under buildings.

Buildings and contents cover compared

The Housing Ombudsman notes that contents insurers may exclude damp and mould because of exclusions for gradually operating causes. In rented homes, buildings insurance is usually arranged by the landlord or freeholder, while tenants normally arrange contents insurance.

If you rent

For tenants, the first route is often not insurance at all. Citizens Advice says that in England landlords are responsible for many rising-damp repairs, and may be responsible for condensation damp in specified circumstances. Report recurring damp in writing, because landlords are usually responsible for repairs once they are aware.

If you bought a new build

Damp in a new home is a different question again. Warranty and builder responsibilities may apply, not household insurance. Our guide on how new build homeowners prove damp is a defect covers the evidence you need.

What to do before you contact your insurer

If there is any chance the damp stems from a sudden event, act in this order.

Stop the cause if it is safe to do so. Turn off the water at the stopcock for a burst pipe. Do not take risks around electrics.
Contact your insurer promptly. The ABI advises contacting the insurer as soon as possible when the home or contents are damaged by an insured peril, including flooding or burst pipes.
Photograph the damage before anything is moved or cleaned. Take wide shots and close-ups, with the date visible if you can.
List affected items and keep receipts. The RAC’s claims guide recommends checking your policy, photographing the damage, listing affected items and keeping supporting evidence.
Keep damaged items for inspection unless they are a health hazard. The ABI says to photograph them if disposal is necessary.
Follow your insurer’s instructions on repairs.

Move paperwork and valuables out of the wet area while you wait. If you keep important items in a cellar or ground-floor safe, in-floor safe waterproofing is worth reading about before the next wet season.

Do not repair first

This is the mistake we see most. In one Financial Ombudsman decision, the insurer said that completing repairs before it could inspect the damage had prejudiced its position. Emergency measures to stop further damage are reasonable. Full strip-out and repair should wait until the insurer agrees.

The ABI also warns in its common questions guide that repairing a flooded property before it is properly dried out can lead to further problems with damp and mould that are not insurable.

Is it a leak, or is it condensation?

Many declined claims turn on this question. A leak is potentially insurable. Condensation is not. The signs overlap, so guessing is risky.

Useful early checks:

Does the patch grow after rain, or after the heating or a bath, or regardless of both?
Is it near a pipe run, a radiator, a roofline or an external wall?
Does the water meter move when everything is switched off?
Is the mould in cold corners and behind furniture, or around a stain with a tide mark?

Our guide to leak versus condensation tests walks through these checks in order. For damp that appears after bad weather, see damp appearing after rain. If you suspect a pipe, leak detection can locate the source without opening up walls unnecessarily.

Why a documented diagnosis helps your claim

When an insurer relies on an exclusion, the question becomes one of evidence. The Financial Ombudsman says that, at the first stage, it is down to you as policyholder to show the damage was likely caused by an insured event. It will look at what the policy covers, and at professional reports and photos.

The Ombudsman also says you are entitled to get your own professional advice. The cost may not be covered, especially if the cause turns out not to be an insured event. Its usual advice is to contact the insurer about the damage first.

In practice, a written report that names the cause, shows where moisture readings were taken and includes dated photographs gives you something concrete to put in front of an insurer or, later, an ombudsman. It also stops you paying for the wrong treatment. A DPC injection will not fix a leaking pipe, and a new damp-proof course will not cure condensation.

Our view: insurance is rarely the answer to damp

We survey damp, mould and timber problems across Dorset, Hampshire and Wiltshire. Dan, our Director and Surveyor, starts every job the same way: look at the symptoms, document the findings and define the scope of work before any treatment is proposed.

Here is what that experience tells us about insurance.

Most damp we are called to is gradual. Failed pointing, blocked gutters, bridged damp-proof courses, poor ventilation and old plumbing joints develop over months or years. That is exactly the territory insurers exclude.
The right question is cause, not cover. If you know the cause, you know whether to talk to an insurer, a landlord, a builder or a specialist.
Photographs and written findings protect you whatever the outcome. We use original project photography so that you can see what we saw.
We stay within our remit. Where a problem needs structural input or another specialist, we say so and refer you on rather than stretching our scope.

If an insured event is behind your damp, tell your insurer first and let them inspect. If it is not, a survey tells you what the fix is and what it will involve.

Book a survey-led inspection

Whether you are preparing a claim or have already been told damp is excluded, we start with an inspection and give you written findings with a defined scope of work. Treatment follows only after that, and our workmanship carries a written guarantee.

Quaypointplastering

Our damp and timber survey covers rising and penetrating damp, condensation and mould, and timber decay. Where the survey finds the cause, we can carry out the remedial work, from DPC injection and black mould removal to damp re-plastering and timber treatment. Book an inspection through our website or call 01202 287134.

If your insurer rejects the claim

A refusal is not always the end. Take these steps.

Ask for the reason in writing, with the policy term relied on.
Check the cause. If the insurer says the damage was gradual and you have evidence of a sudden event, send that evidence, such as a plumber’s report, dated photos or a survey.
Make a formal complaint to the insurer. The Financial Ombudsman says that if you do not receive a final response within eight weeks, or you are unhappy with it, you can bring the complaint to the Ombudsman. The service is free.
Understand the burden of proof. The Ombudsman says that where an insurer first accepts the damage looks insured and then relies on a gradual-damage term, it must explain why it relied on that term.

The Ombudsman may also uphold part of a complaint where an insurer handled a claim with poor communication or delay, even if the decision to reject the claim was fair. Where the evidence is unclear, it decides what most likely happened on the balance of probabilities, as set out in the published decision.

FAQ

Can I claim on home insurance for damp?

Only if the damp results from an insured event such as a burst pipe, storm or flood. Rising damp, condensation and slow leaks are generally excluded as gradual damage or lack of maintenance. Read your policy wording and ask your insurer before you assume either way.

Does home insurance cover mould?

Not usually on its own. Mould that follows a sudden, covered escape of water may be included in the claim, but mould caused by condensation or long-term damp is normally excluded. Some insurers also specifically exclude rot.

Does buildings insurance cover rising damp?

Most standard policies do not. Some insurers offer specific rising damp cover as an extra, so check whether yours does. A damp specialist’s written guarantee on treatment is a separate matter and is not insurance.

What should I do first if I find damp?

Work out the cause before you spend money. If you suspect a burst pipe or storm damage, photograph it and contact your insurer before repairing anything. If the signs point to a gradual cause, book a survey so you have written findings and a clear scope of work.
