A burst pipe is a pressurised pipe that has split or come apart at a joint, so it releases water continuously until the supply is turned off. That is what makes it different from a slow weep, and it is why the cost of a burst is decided as much by the first ten minutes as by the plumber's invoice. This guide covers what a burst pipe repair typically costs in the UK, what pushes the figure up, and how home insurance usually handles it.
What should you do in the first ten minutes?
The water safety advice from WaterSafe, the UK register of approved plumbers, is the sensible order:
- Turn off the internal stopcock, usually under the kitchen sink or where the supply enters the property, by turning it clockwise.
- Switch off the central heating or boiler. If you have a hot water cylinder with an immersion heater, switch that off too.
- Open the hot and cold taps to drain what is left in the pipes and take the pressure off.
- If water has reached any electrics, switch off the electricity at the consumer unit first, but only if the consumer unit itself is dry and safe to reach.
- Contain the water with towels and buckets, and move belongings out of the way.
- Photograph the damage before you clear it, then call a plumber.
If the stopcock is seized or you cannot find it, the external stop tap near the boundary may isolate the property, although in shared supplies and blocks of flats it may also cut off neighbours. If water is coming through a ceiling, keep everyone out from under any bulge and keep the lighting circuit off.
How much does it cost to fix a burst pipe?
Published UK price guides from 2025 and 2026 put a straightforward burst pipe repair at roughly £150 to £400, with larger jobs running higher. Plumber labour is commonly quoted at around £40 to £60 an hour nationally, with London rates above that, and emergency or out-of-hours call-outs usually add a separate fee. These are typical UK market ranges from trade price guides, not quotes from us.
That range assumes the pipe is reachable: under a sink, in a loft, in a cupboard or behind a panel. It covers the plumber's time, a coupling or short length of pipe and fittings. It does not include finding a burst you cannot see, opening up walls or floors, or putting right the water damage.
What makes a burst pipe repair cost more?
| Situation | Why the cost rises |
|---|---|
| Burst pipe hidden in a wall, floor or ceiling | The break has to be located, then opened up and made good afterwards |
| Pipe buried in concrete or screed | Breaking out and rerouting take longer than a joint repair |
| Night, weekend or bank holiday | Out-of-hours rates and call-out charges |
| Frozen pipework in a loft or outbuilding | More than one split is common once a run has frozen |
| Old or corroded pipe | A section may need replacing rather than one joint |
| Heating pipe rather than water supply | The system has to be drained, refilled, bled and repressurised |
| Supply pipe outside the building | Excavation, and the pipe may be in a shared or awkward route |
The biggest jump is from "visible" to "hidden". When a pipe bursts behind a tiled wall or under a floor, the water can appear some distance from the break. Opening up where the water shows is a common and expensive mistake.
What if you cannot see where the pipe has burst?
With the stopcock off, a hidden burst stops flowing, which also makes it harder to find. A leak detection engineer will usually pressure test the pipework to confirm which section is losing water, then use acoustic listening, thermal imaging or tracer gas to narrow down the point. The aim is a marked location so the plumber opens one small area.
Our emergency leak detection is priced at £300 to £500, and a standard acoustic or thermal survey starts from £150 during working hours. Both include a written report you can give to your insurer.
Does home insurance cover a burst pipe?
Most buildings insurance policies cover sudden damage caused by water escaping from fixed pipes and heating systems, which is usually called escape of water. A burst pipe is the classic example. Contents cover may pay for damaged belongings. But there are several points to check in your own policy, because wording differs between insurers and between policy levels.
- The pipe itself. Many policies pay for the damage the water caused but not for repairing the pipe that failed. Some do include the repair. Check your wording.
- Trace and access. If the burst is hidden, trace and access cover may pay to find it and open up. It has its own limit, which varies by policy.
- The excess. Many insurers apply a higher excess, or an additional excess, to escape of water claims.
- Unoccupied homes. Policies commonly restrict or remove escape of water cover if the home was unoccupied or unfurnished for longer than a set period, often around 30 or 60 days. Check the number in yours.
- Winter conditions. Some policies expect you to keep the home heated or drain the water system when you are away in cold weather.
- Wear and tear. Damage that built up slowly, or a failure put down to age and lack of maintenance, is often excluded.

Why do pipes burst?
Freezing is the best known cause. Water expands as it turns to ice, and pipes in lofts, garages, outbuildings and on external walls are most exposed. The split often only starts leaking when the ice thaws. Other common causes include push-fit or compression joints that have worked loose, pipes pierced by a screw or nail during building work, corrosion in older pipework, and excessive water pressure. Our article on why pipes leak goes into these in more depth.
What about the water damage?
A burst releases water quickly, so the damage is often the largest part of the cost: ceilings, plaster, flooring, kitchen units, and in flats, the property below. Before anything is reinstated, the structure has to dry out properly, otherwise new plaster and flooring can fail and mould can develop. Moisture readings taken before and after drying are useful evidence for the insurer and for the contractor who signs the work off.
When should you call a leak detection specialist?
If you can see the split and reach it, a plumber is all you need. Call a leak detection specialist when:
- water is appearing but you cannot see a broken pipe;
- the water meter still moves after the obvious leak has been fixed;
- the boiler keeps losing pressure after a heating burst was repaired;
- your insurer wants a report showing the location and cause before approving access work.

Frequently asked questions
How much does it cost to fix a burst pipe in the UK?
Trade price guides put a straightforward, accessible repair at roughly £150 to £400. Hidden bursts cost more because of the work to find the break, open up and make good, and out-of-hours call-outs add to the bill.
Should I claim on insurance for a burst pipe?
Compare the likely cost of the damage with your escape of water excess, which is often higher than the standard excess. For a small, visible repair with little damage, a claim may not be worthwhile. For a hidden burst with damaged ceilings or floors, it usually is. Your insurer or broker can confirm what applies.
Can I temporarily fix a burst pipe myself?
Pipe repair clamps and repair tape can slow a small split on an exposed pipe until a plumber arrives, but they are not a permanent repair. Turning off the stopcock is always the first step, and a hidden burst cannot be patched from outside the wall.
Will the water company fix a burst pipe on my property?
Water companies are generally responsible for their own mains and pipework up to the property boundary. Pipes inside your boundary and inside the building are usually the owner's responsibility, so check with your water supplier if the leak is near the boundary or the stop tap.
How long does a burst pipe repair take?
An accessible repair is often done within an hour or two of the plumber arriving. Hidden bursts take longer because of locating, opening up and, later, drying and reinstating.
