Stop the water first
With a burst pipe, stop the water, keep clear of electrics and establish whether the run is mains-fed, tank-fed, part of a heating circuit or communal. Try the internal stop tap, but its location varies; if water continues, a stored-water system, another dwelling or communal pipework may still be feeding it. Do not operate shared valves without authority. Drain or isolate only the affected system where safe, then record the temporary action for the permanent repair.
If the burst is a frozen pipe that hasn’t split yet, turning off the water and gently warming the pipe (never with a naked flame) can prevent it from bursting as it thaws. Once the water’s off and it’s safe, a verified plumber can repair or replace the failed section.
Why pipes burst — diagnose the actual cause
Some properties may contain pipework in unheated lofts, cellars, outbuildings or external runs where freezing is possible. Other bursts result from corrosion, movement, failed joints, accidental damage or previous alterations. The age of the building does not establish the age or condition of its pipework, so the failed section and adjacent joints should be inspected rather than assuming a “period-house” cause.
Thames Water confirms that the regional supply is hard and limescale deposits can form, but hardness alone does not establish why a pipe burst. The repair decision should be based on the actual material, corrosion, movement, pressure, freezing exposure and previous work found on site.
A plumber should first establish whether the burst is on a mains supply, stored-water pipe or sealed heating circuit, isolate the correct system and make a temporary or permanent repair. Before restoring service, they should pressure-test or otherwise test the repaired run, inspect nearby joints and previous repairs, and confirm that isolation has not cut off another dwelling. Where the correct fitting is unavailable, temporary capping may be the safe first-visit outcome. Photographs and a repair note can support an insurer or landlord claim.
Safety first
A burst is mainly a water problem, but electricity and gas can make it dangerous. Keep clear of water near electrical fittings and involve an electrician where safe electrical isolation or testing is required. If gas is smelled or a leak is suspected, follow the National Gas Emergency Service guidance and call 0800 111 999 from outside.4 Any gas work must be done by a Gas Safe registered engineer.5
Find a verified plumber by area
- Dulwich Village (SE21) — systems vary by property. Confirm whether the burst is private, shared or on an external route and whether the specific permanent repair would trigger Estate consent.
- East Dulwich (SE22) — in a converted house, one stop tap may affect more than one flat. Confirm who else is supplied before isolation and coordinate access where water is affecting the flat or business below.
- West Dulwich (SE21) — a burst in a mansion or managed block may be on a communal riser or inside a service duct. The managing agent or authorised contractor may need to isolate and provide access.
- Dulwich Wood & Sydenham Hill (SE21/SE26 edge) — some properties have external or buried garden supplies. Confirm the route, ownership and condition rather than assuming freeze damage from the location or age of the building.
- Herne Hill edge (SE24) — the western fringe that crosses into Lambeth, where council routing differs.
What it costs
A burst repair is priced by how accessible the failed pipe is and whether it’s out of hours. The figures below are an editorial estimate only — not regulated rates, not market data, and not a published cost survey. Agree the price before work starts, and see How to read a plumbing quote and the London plumbing costs guide.
| Burst-pipe job (indicative) | Typical range |
|---|---|
| Emergency call-out / first hour | £90–£170 |
| Repair a burst or split pipe (accessible) | £120–£300 |
| Isolate & make safe | £90–£200 |
| Burst under floor / in wall (trace & access) | Quoted |
| Replace a section of old / lead pipe | Quoted |
Dulwich (SE21/SE22) sits inside the London-wide ULEZ, which Transport for London operates across every London borough, but outside the central Congestion Charge zone.6 It’s reasonable to ask whether any emissions-zone charge is included. VerifiedPlumbers is a directory that connects you with verified plumbers; it doesn’t carry out the work itself.
Frequently asked questions
Turn off the stop tap, open the cold taps to drain down, turn off the loft tank’s outlet if you have one, switch off the boiler if a leak is near it, and keep clear of electrics. Then call a plumber.
Sometimes. Turn off the water and warm the pipe gently — a hairdryer or warm cloths, never a naked flame — working from the end nearest the tap. If it has already split, leave the water off and call a plumber.
Some properties have pipes in unheated lofts, cellars, outbuildings or external runs that can freeze. Insulating exposed pipework and isolating suitable outside supplies can reduce risk, but the cause of a particular burst must be confirmed on site.
A one-off failure on otherwise sound pipework may be repaired. If inspection finds corrosion, movement, repeated repairs or unsuitable material nearby, a longer section may need replacement. Property age alone is not evidence that the pipework is old.
The emergency make-safe doesn’t need Estate consent. A permanent repair that’s structural or adds an external pipe can, under the Scheme of Management — mention it when arranging the follow-up work.

Why verified plumbers — not a general directory
A burst is urgent, and urgency is where corners get cut and prices inflate. Every listing is checked before it goes live and re-verified annually: we confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, and we confirm the plumber covers Dulwich’s SE21 and SE22 postcodes before a profile is approved. You can also verify a plumber yourself on WaterSafe, the free, water-industry-backed national register.7
Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. There is no pay-to-play ranking and no per-enquiry middleman fee: enquiries go directly to the plumber.

With a burst, stop the water, keep clear of electrics and establish whether the failed run is mains-fed, tank-fed, heating or communal. A converted house or mansion flat may have shared isolation, while a business or flat below may need immediate protection. The plumber should test the repair and adjacent joints before restoring supply, and Estate consent remains conditional on the specific permanent work.
