London Leak Specialist

Stop the water. Then fix it properly.

Burst Pipe Repair London

A burst pipe is the loudest emergency in plumbing: water pouring through a ceiling, a soaked carpet spreading by the minute, a stop tap that will not turn. The first job is always the same, stop the water now. Everything else can be planned; the flooding cannot.

What burst pipe repair costs in London

The question almost everyone asks first is what it will cost, and most sites answer it with a range so wide it is useless. Ours is straightforward because the rate is the same one published on our pricing page and it does not move once you have been quoted.

  • Working hours, straightforward repair: £160 an hour. A split on an accessible run of copper, a failed compression joint or a burst flexi under a sink is usually inside the first hour or two.
  • Emergency and out of hours: from £220 an hour, confirmed as an exact figure when you book rather than after the visit.
  • Where the pipe has to be found first: detection is charged separately at its own rate, £160 an hour internally and £180 for a buried supply pipe, because locating a burst under a floor is a different job from repairing one you can see.
  • Parts and making good: quoted separately once the pipe is exposed. Pipe, fittings and a section of plasterboard are minor; a run of screed, a tiled floor or a repaired ceiling is not, and that is where two otherwise identical bursts diverge in price.

There is no separate call-out charge on a booked visit. The clock starts when the engineer starts work, not when the van leaves.

What makes one burst pipe cost more than another

Four things, in roughly this order of impact.

Where the pipe runs. A burst on an exposed pipe in an airing cupboard is an hour. The same burst in a pipe cast into a screed floor means locating it, opening the floor and reinstating it afterwards, which is a different order of work.

How long it ran. A pipe that let go twenty minutes ago and one that has been weeping into a ceiling void for a fortnight cost the same to repair and nothing like the same to put right. This is the single largest factor in the final bill, and it is the one you can still influence by turning the water off now.

The hour it happened. Out of hours attendance is charged at the emergency rate. If the water is isolated and nothing is still spreading, booking the repair for the next working day is often the cheaper and equally safe choice, and we will say so on the phone rather than dispatching a van.

What else it took with it. The repair is the pipe. Drying, plastering, flooring and decorating are separate trades and separate costs, and they are usually the part a buildings insurance claim is actually for.

If you intend to claim, photograph everything before anything is cleaned up or opened, and read what escape of water cover pays for. The repair of the pipe itself is commonly the homeowner's, while the damage the water caused is the claim.

Quick answer

Isolate the water at the stopcock first, then call for help. In London, an emergency burst pipe repair typically starts with a call-out plus the first hour of labour. Out-of-hours work in the evening, at weekends or overnight carries an uplift on the standard daytime rate. Parts and reinstatement are extra.

Typical UK trade cost-guide ranges, not a quote. Our detection is charged at a fixed hourly rate quoted at booking, under no find, no fee.

Our emergency response prioritises isolation: finding and closing the right valve, draining the affected circuit and protecting what has not yet been soaked. Then the burst is repaired properly, full-bore repair, not tape and hope, and the system is refilled and tested.

Before we leave, you get photographs and a clear note of the cause, because a burst pipe almost always becomes an insurance conversation.

Emergency call-outs are quoted transparently when you book, no arrival-and-surprise pricing.

What you get

  • Emergency isolation as the first priority
  • Frozen, corroded and mechanically-damaged bursts repaired
  • Stop tap location and replacement when yours has seized
  • System drain-down, refill and pressure test
  • Cause-of-damage documentation for insurance
  • Follow-up detection if the burst hints at wider pipework failure

How it works

Isolate, locate, repair, in that order

01

Isolate immediately

We locate the working valve, internal stop tap, boundary valve or riser, and shut the water off.

02

Limit the damage

Drain-down and containment protect floors and ceilings still at risk.

03

Repair full-bore

The damaged section is cut out and replaced, not patched.

04

Refill and verify

Pressure returns, joints are checked, and the cause is documented.

Before you book anyone

7 things to know before you book burst pipe repair in London

01

Turn off the stop tap before you phone anyone

The first five minutes decide whether you face a plumbing bill or a reinstatement bill. UK homeowners typically spend £500 to over £5,000 putting right water damage after a burst pipe, collapsed ceilings and saturated timber floors sit at the top of that range. Your internal stopcock is usually under the kitchen sink; there is often an external stop valve at the property boundary too. Shut the water off, open the cold taps to drain the system, and switch off the boiler. Only then start ringing round. A burst pipe with the water already off is a far cheaper problem to book.

02

Get the full price in writing before anyone is dispatched

Most overcharging happens when a panicked caller agrees to "send someone now" with no figure attached. Trading Standards has prosecuted online plumbing operations, and documented cases include contracts presented on the doorstep at £279 per hour, with the clock starting at signature. Before any engineer leaves the depot, get the call-out fee, hourly rate, minimum charge and VAT treatment confirmed by text or email. For context, Checkatrade puts the average emergency call-out fee at around £110, with London first-hour rates of £80–£150 in the daytime. A firm that will not put numbers in writing is telling you something.

03

Know what the repair should actually cost

A straightforward burst on an accessible 15mm pipe typically costs £150–£270 all-in, including the call-out, and takes one to three hours, the copper and fittings themselves cost under £15. A burst behind a wall or under a floor is different: once you add opening up, replacing the section and making good, £450–£900 is the realistic range. London prices run roughly 20% above the UK average across the board. Keep those brackets in mind when an invoice lands. A four-figure bill for a visible pipe under the sink deserves a written breakdown before you pay it.

04

Beware the cheap hourly rate on a hidden burst

£80–£120 per hour looks reasonable until nobody knows where the pipe has actually failed. A concealed burst under a screed floor or behind tiling can absorb hours of exploratory chasing, at open-ended hourly billing, with holes in your walls whether the leak is found or not. If the water is escaping somewhere you cannot see, detection should come before demolition. A fixed hourly detection rate agreed at booking (typically £320–£640 in total for a London home, using acoustic, thermal, tracer gas and moisture mapping together) usually works out cheaper than paying someone to guess by the hour, and it is the model we work to.

05

Check who actually owns the pipe before you pay to fix it

Responsibility splits at your property boundary. Thames Water (and the other London suppliers) own the mains and the communication pipe up to the boundary; the supply pipe from the boundary into your home is yours, including the stretch under your garden or driveway. If one supply pipe serves several properties, the shared section is a joint responsibility with your neighbours, and so are the costs. Two practical points: report suspected external bursts to your water company before booking private work, and note that once a leak on your side is confirmed, you are legally required to arrange repair within four weeks.

06

Read the no-find-no-fee small print

"No find, no fee" ranges from a genuine guarantee to a marketing line. Review sites carry complaints from customers charged the full fee after a firm identified the wrong leak, and some guarantees quietly exclude heating circuits or commercial pipework. Before booking, ask three questions: does the guarantee apply to my type of leak, what counts as a "find", and what happens to the fee if the repair proves the diagnosis wrong? Ask too whether the report will state cause, origin, method and moisture readings, that is what a UK loss adjuster needs, and a one-line invoice will not survive a claim.

07

Pay by card, never cash up front

Demands for cash before work starts are a documented red flag in UK plumbing scams, legitimate firms invoice on completion or take a small deposit for expensive parts at most. Paying by credit card gives you Section 75 protection on jobs over £100, which means the card company shares liability if the work is defective or the trader disappears. Insist on a written job sheet describing what was done and which section of pipe was replaced: you will need it for any insurance claim, and asking for it up front tends to keep the invoice honest. Report pressure tactics to Trading Standards.

Burst Pipe Repair Across London, Done Properly

A burst pipe can flood a room in minutes, so the response matters as much as the repair. This page sets out how we handle burst pipe call-outs in London: an honest arrival window, a price agreed before we travel, isolating the water first, and tracing hidden bursts with proper leak-detection kit rather than guesswork.

Questions

Burst pipes: cost, insurance and stopping the water

How much does burst pipe repair cost in London?

Repair labour is £160 an hour in working hours and from £220 an hour out of hours, with the exact figure confirmed when you book. Most accessible bursts are dealt with inside one to two hours. Parts and making good are quoted separately once the pipe is exposed, and where the burst has to be located first, detection is charged at its own rate.

Why do burst pipe repair costs vary so much between quotes?

Because the pipe is rarely the expensive part. Where it runs decides whether the repair is an hour or a day, how long it leaked decides how much has to be dried and made good, and the hour you call decides whether the emergency rate applies. A quote given before anyone has seen where the pipe is should be treated as a guess.

Is it cheaper to wait until the morning?

If the water is isolated at the stopcock and nothing is still spreading, yes, and we will tell you so on the phone rather than send a van at the emergency rate. If water is still running, or it is running into a ceiling or near electrics, it is not worth waiting and we will attend.

What should I do right now, before anyone arrives?

Turn off the internal stop tap, usually under the kitchen sink or where the mains enters. If it will not budge, use the outside boundary valve at the property line. Open cold taps to drain pressure, switch off the boiler, and move electronics away from the water. Then call us.

Why do pipes burst in winter?

Water expands roughly 9% when it freezes. Ice forming inside a pipe generates enormous pressure between the blockage and a closed tap, splitting the pipe, often silently. The flood comes at thaw, when the ice plug melts and the split opens up.

Will insurance cover a burst pipe?

Escape of water is one of the most common buildings insurance claims, and sudden bursts are generally covered, including resulting damage. Our documentation of the cause and repair supports the claim from day one.

Is a burst pipe an emergency?

It is an emergency while water is escaping and you cannot stop it. Turn off the internal stopcock (usually under the kitchen sink), open the cold taps to drain the system, and switch off the boiler. If that stops the flow, the situation is controlled and a daytime appointment is usually fine, and considerably cheaper than an out-of-hours call-out. If you cannot isolate the water, or it is reaching electrics or a neighbour's property, treat it as urgent and book immediate attendance.

How long does it take to fix a burst pipe?

A visible, accessible burst is normally repaired in one to three hours, including isolating the water and replacing the failed section. Concealed bursts take longer because the pipe must be located first, a multi-method detection survey typically takes two to four hours, followed by opening up, repair and making good. Drying out the surrounding structure is the slowest part: saturated walls and floors can need days to weeks of dehumidification before redecoration.

Who is responsible for a burst water pipe?

It depends where the pipe is. Your water company (Thames Water for most of London) is responsible for the mains and the communication pipe up to your property boundary. From the boundary into your home, the supply pipe is the homeowner's responsibility, even where it runs under a garden or driveway. Shared supply pipes serving several properties are a joint responsibility between the owners. Once a leak on your side is confirmed, you are legally required to arrange repair within four weeks.

Does home insurance cover a burst pipe?

Usually in part. Most UK buildings policies cover escape-of-water damage, ruined ceilings, floors and decoration, and many include trace-and-access cover, which pays for finding the leak and opening up walls or floors to reach it. What is typically not covered is repairing the failed pipe itself, which stays the homeowner's cost. Claims succeed or fail on documentation: loss adjusters expect evidence of cause, origin and extent, so keep photos, the engineer's job sheet and a proper detection report.
