What is 'sudden escape of water'?
'Escape of water' is the insurance term for water leaking or overflowing from a pipe, tank, appliance or fixed water system inside your home - for example a burst pipe or an overflowing washing machine. When it happens suddenly and accidentally, it is one of the most common covered claims. Water building up slowly over time is treated differently and is often excluded.
'Escape of water' is the insurance industry's name for water getting out of where it should be inside your home - a burst or leaking pipe, an overflowing tank or cistern, or a failed appliance like a dishwasher or washing machine. It is one of the most frequent home insurance claims in the UK, and most policies list it as a standard covered peril under both buildings and contents cover.
The word 'sudden' is doing a lot of work. Cover is aimed at events that happen quickly and without warning - a pipe splitting, a hose bursting, a tank suddenly failing. Because these are unforeseen accidents, they fit what insurance is designed to protect against, and the resulting damage to your structure and belongings is normally covered.
It helps to know that escape of water is different from flood. Escape of water is an internal problem - water from your own plumbing or appliances. Flood is external - water coming in from outside, such as a river or surface water. They sit in separate sections of your policy, and mixing them up can lead to claiming under the wrong heading.
Insurers treat escape of water claims on different terms from other perils. Policies often apply a higher excess for escape of water, somewhere around £250 to £500, because these claims are so common. Your policy schedule will show the exact figure, so it is worth checking before you claim.
Because escape of water can cause extensive hidden damage - under floors, inside walls, behind units - the full cost is not always obvious at first. If you want to be sure a settlement reflects the true extent of the damage, our escape of water claim guidance explains what to look for.
What counts as escape of water
The term covers water leaving a fixed water system or appliance inside the property. In practice that means:
- Burst, split or leaking pipework, including pipes under floors and inside walls.
- Overflowing or failed water tanks and cisterns.
- Washing machines, dishwashers and fridge freezers that leak or whose hoses fail.
- Central heating systems and radiators, including leaks from valves and joints.
- Baths, showers and basins that overflow, though a shower leaking through failed sealant is usually treated as maintenance instead.
Why the excess is higher
Escape of water is among the most frequent and most expensive causes of home insurance claims in the UK, which is why policies commonly attach a separate, higher excess to it, often in the region of £250 to £500 where the standard excess is lower.
Two details catch people out. Buildings and contents are separate sections, so a leak that damages both can attract an excess on each. And a policy that carried a standard excess when you bought it may have had a specific escape of water excess added at renewal. Your schedule, rather than the policy booklet, shows the figures that apply to you.
Escape of water, flood or storm: a quick test
Claiming under the wrong heading wastes time and can produce a refusal that reads worse than it is. The test is where the water came from.
Water from your own plumbing, tanks or appliances is escape of water. Water that entered from outside at ground level, from a river, the sea, surcharged drains or surface run-off, is flood. Water that came in through the roof or a window during violent weather is storm. Each sits in a different section, sometimes with a different excess, and the same incident can occasionally trigger more than one.
Hidden leaks and the cost of finding them
The most expensive escape of water claims tend to be the ones nobody saw. Water from a pipe under a solid floor or inside a wall cavity can run for weeks, spreading through the structure and reaching rooms away from the source before anything appears at the surface.
Finding it costs money before any repair starts: leak detection surveys using thermal imaging or acoustic equipment, then lifting floors or opening walls to reach the pipe. That search and reinstatement cost is what trace and access cover pays for, and it is usually capped separately from the rest of the claim.
Warning signs worth acting on are a water meter that keeps moving when everything is turned off, an unexplained rise in the bill, warm patches on a floor above heating pipes, and a musty smell with no visible source.
