Does House Insurance Cover Chimney Repairs?

Buildings insurance is written around events. A gale that tips a pot off the stack is an event. Mortar that has been eroding over a long time is wear, and policies treat the two very differently. A chimney can suffer both at once, which is where a claim gets complicated.

How is a storm defined?

For the Financial Ombudsman Service, a storm means a spell of violent wind, often joined by rain, hail or snow. That is the Ombudsman's own yardstick, and a policy may spell out a definition of its own. A stack that comes down in a named storm fits the idea more clearly than one that cracked in a calm spell, so the date of the weather matters when you report it, and a note of the wind forecast for that night is worth keeping.

Pictures taken at the time carry weight. The Institution of Structural Engineers treats photos as the key evidence for a storm claim. Stand well back, shoot before anything is moved or swept up, and add wide views that show where the debris landed and which way it fell.

Tell the insurer before you do anything else. Then make the area safe, and keep clear of anything that could fall, including tiles and bricks that have landed in the garden or on a shed roof. The order matters, because some insurers want to see the damage or agree the work before it begins.

Should the repair wait for a reply?

Insurers generally expect you to limit further harm with a stopgap, and to keep pictures from before and after plus every receipt. Permanent work normally waits until the insurer has said what it will accept, so ask what it needs before you order anything, and ask whether it wants its own assessor to visit first. If a pot or stack is moving or looks ready to fall, rope off the ground beneath it and leave the testing to a roofer.

When a roof is leaking, the roofer first stops the leak, and you get pictures of the damage on your own roof. Our page on chimney storm damage covers what that involves, and the photos and the written price from our survey are yours to pass to the insurer if it asks for them.

Policies differ, and the small print matters more than the headline.

Which clauses decide a chimney claim?

Look at how the policy defines a storm. Check whether it excludes wear and tear, gradual deterioration or poor maintenance. See whether it names chimneys, pots or aerials. Find the excess, the amount you pay before the insurer pays anything. Then ask the insurer to put its answer about your chimney in writing, so that you are not relying on a phone call.

Which? reports that only 32% of storm-related claims made in 2024 resulted in a payout, so both the wording and the evidence count. A clean record of the damage, taken straight after the weather, is the strongest thing you can bring to the conversation, and it costs nothing to make. Keep the date, the time you noticed the damage and what the weather had been doing.

What about crumbling mortar or old flaunching?

Those are wear, and wear is the category least likely to be paid. Treat repointing and flaunching as upkeep, and read crumbling chimney bricks for the causes and the repair.

A no from the insurer can be challenged. Complain to the insurer first, in writing, and ask for its final response.

Where can a complaint go next?

Should the insurer stay silent for eight weeks after you complain, the Financial Ombudsman Service can step in. When a reply does come, you have 6 months from the date of that last letter to go to the Ombudsman, and there is no charge. Keep the policy, the pictures, the receipts and every letter together in one folder, since they make up your file. A short timeline of who said what and when makes the case easier for anyone reviewing it.

Meanwhile the chimney still needs attention. A stack that is moving is dangerous whoever ends up paying, so arrange a survey. We show you pictures of the stack, explain what needs doing and give one written price. Our chimney repairs page lists the jobs, and a survey is the sensible next step if the insurer's answer leaves your chimney untouched.
