Burst pipe insurance claim: what's covered and how to claim
A burst pipe is a classic 'escape of water' claim and most UK home insurance covers it. Turn the water off, photograph everything before clean-up, and do not accept a low offer. Burst pipe claims are almost always larger than they first appear.
Key takeaways
- A sudden burst is the textbook covered claim. Insurers pay for the damage the water caused, not usually for the pipe repair.
- Frozen pipes are normally covered, unless the home was empty beyond the policy limit or was left unheated.
- Water under mains pressure reaches every floor fast, so the damage is rarely confined to the room where it started.
- Trace and access, drying and alternative accommodation belong in the claim alongside the obvious repairs.
Is a burst pipe covered by home insurance?
Almost always. A sudden, accidental burst pipe is the textbook escape of water claim, covered as standard on UK buildings and (for your belongings) contents policies. Note what that covers: insurers pay for the damage the water causes, not usually for fixing the failed pipe itself. Some policies do pay to repair a pipe that burst because it froze, so check your wording rather than assuming either way.
What causes pipes to burst
Knowing the cause matters, because the insurer will ask and the answer decides the claim.
- Freezing. Water expands as it turns to ice, pressure builds between the ice plug and a closed tap, and the weakest point splits. The leak often appears when the thaw comes rather than during the freeze. Pipes in lofts, garages, outbuildings and against external walls are the most exposed.
- Corrosion and age. Older copper and steel pipework thins over time. A pipe that finally gives way is a sudden failure, though an insurer may reach for wear and tear, which is why a plumber's description of the failure matters.
- Movement and poor support. Pipes that are not clipped properly work against joints, especially where heating causes expansion.
- Pressure. High mains pressure, or a failed pressure reducing valve, puts strain on joints and flexible connectors.
- Impact. A nail or screw through a pipe during building work, or a knock in a loft.
Frozen pipes and the empty home trap
Frozen pipes that burst are usually covered, and this is where insurers push back hardest. Most policies limit or withdraw escape of water cover once a home has been unoccupied beyond a set period, commonly 30 or 60 days, and many also require you to take reasonable precautions in cold weather.
In practice that means one of two things while you are away in winter: leaving the heating on at a low setting throughout, or turning the water off at the stopcock and draining the system down. If you were away, gather whatever shows what you did, such as smart thermostat history, a neighbour who checked the house, or the dates you were absent.
Timing is worth knowing here. Escape of water claims peak in January, yet a quarter of them arrive between July and September, when homes are often empty for holidays. An empty house is the risk, not only the cold.
Sudden vs gradual
A sudden burst is covered; a slow leak you should have noticed and fixed is often called wear and tear and refused. Evidence that the failure was sudden is what wins the claim.
What to do in the first hour
- Turn off the water at the stopcock and open the taps to drain the system.
- Switch off the electrics at the mains if water is anywhere near sockets, the consumer unit or light fittings.
- Photograph and video everything before you clean up or move anything.
- Move what you can clear of the water, and contain the spread where it is safe to do so.
- Keep receipts for any emergency plumber, drying equipment or temporary repairs.
- Report the claim and get a reference. Do not start permanent repairs before the scope is agreed.
What you can claim for
A full burst pipe settlement usually includes more than the obvious:
- Buildings: structural drying and repair to walls, ceilings, floors and plaster.
- Contents: ruined carpets, furniture and belongings at their proper value.
- The cost of finding the leak: lifting floors or opening walls to reach it, and reinstating afterwards.
- Alternative accommodation: if your home is uninhabitable during repairs, plus the extra costs of being out.
Scale is the thing homeowners underestimate. Water released under mains pressure for even a few hours can reach every floor of a house, travelling along joists and into cavities long before it shows on a ceiling. The published benchmark for the category is an average of £8,548 for damage from flooding, storms and burst pipes in the second quarter of 2026, so treat an offer of a few hundred pounds with suspicion if drying or a lifted floor was involved.
The excess, and whether to claim
Escape of water often carries a higher excess than other perils, commonly £250 to £500, and your policy schedule shows the figure. On a burst pipe that damaged more than the pipe itself, the repair is normally well past that number, so the calculation is usually straightforward. Where it is close, read whether it is worth claiming first.
If your claim is refused or underpaid
A refusal is not final, and a low offer is an opening figure. Ask for the reasons in writing, answer them with evidence, and escalate to the Financial Ombudsman if the insurer will not move. On a larger claim, a loss assessor working for you can renegotiate the settlement.
Start with the reason you were given: the claim was denied, the offer is too low, or nothing is happening. The full claim process is in how to make a successful water leak claim.
