Does home insurance cover a burst pipe or burst water main?
Yes, most UK home insurance policies cover damage from a burst pipe, because it is a sudden and accidental event - this falls under the 'escape of water' section of your buildings and contents cover. Cover usually includes the damage the water causes and 'trace and access' - finding and reaching the leak. A burst main in the public road, however, is the water company's responsibility, not your insurer's.
A pipe that suddenly bursts - often in a cold snap when water freezes and expands - is exactly the kind of sudden, accidental event home insurance is designed for. Buildings insurance typically covers repairing damage to the structure, such as soaked ceilings, floors and walls, while contents insurance covers ruined belongings. Many policies also cover the cost of drying out your home and replacing damaged decoration.
A useful feature to look for is 'trace and access'. This covers the cost of finding a hidden leak and getting to it - for example lifting floorboards or removing part of a wall - and then making good afterwards. Without it, the cost of locating a concealed burst pipe can fall on you, so it is worth checking whether your policy includes it and up to what limit.
There is an important distinction between a burst pipe in your home and a burst water main in the street. Pipes inside your property boundary are generally your responsibility and your insurer's concern. The mains supply in the public highway belongs to your water company - if that bursts and floods your home, you may need to raise it with the water company, though your own insurer can still help with the damage to your property.
One common trap is frozen pipes while a home is empty. Many policies expect you to take reasonable care - keeping the heating on low in winter, or draining the system if the property is left unoccupied for an extended period. If a pipe bursts because these conditions were not met, an insurer may reduce or decline the claim, so check the 'unoccupied property' conditions in your wording.
If a burst pipe has caused significant damage and you want to make sure the claim reflects the full cost of putting things right, our burst pipe claim guidance walks through what to document and expect.
