A burst pipe doesn’t wait — water spreads fast and the damage mounts by the minute, and the worst of it lands in winter, when a frozen pipe thaws and splits. Every plumber here is checked and verified before listing, so once the water’s off you can call one with confidence.

⚠️ Water near electrics, or coming through a ceiling light or fitting? Treat it as live and dangerous — don’t touch switches or anything wet, get the water off at your stop tap, and switch the power off at the mains only if you can reach it safely and dry. More on staying safe ↓

Frozen, split or blown: why pipes burst — and what to do now

Pipes burst for a handful of reasons, and in London the biggest is the freeze–thaw cycle. Thames Water explains that in cold weather the water in a pipe can freeze, and when the temperature rises and it thaws, the pipe may crack or burst — which is why bursts often appear as the weather warms after a cold snap, not during the freeze itself.¹ Other common causes are age and corrosion in older pipework, sudden pressure changes or “water hammer”, a failed joint, valve or flexible hose, and physical knocks.

If a pipe has burst, the order matters. Thames Water sets out the basic steps: find your stop tap — usually under or near the kitchen sink — and turn it clockwise to stop the water, then turn off the heating and open all the taps to drain the system quickly and take the pressure off the burst.¹ Soak up standing water, move anything valuable, and photograph the damage for insurance before you clear up. And if water is anywhere near your electrics, switch the power off at the mains and don’t touch anything electrical that’s wet.¹

For a frozen-but-not-yet-burst pipe, the same source advises turning the stop tap off, opening the taps so water can escape as it thaws, removing nearby items you want to keep dry, and thawing the pipe slowly and gently — a wrapped hot-water bottle or warm towels, never a naked flame — then checking carefully for leaks before turning the water back on.¹

Once it’s safe, what happens next depends on the pipe — and a good plumber’s first job is to work out exactly what’s burst: a mains cold feed, a hot supply, a heating-circuit pipe, cylinder pipework or a communal riser, because that decides the repair. A clean split on an accessible run can often be cut out and a new section fitted, or a failed isolation valve or compression joint swapped, the same day. But a first visit may only isolate, cap or make safe the burst if the pipe is buried, communal, badly corroded or needs specialist access, with the permanent repair booked in afterwards. Repeated bursts on old, furred or corroded pipework usually point to re-piping that stretch rather than patching it again.

If the burst is on a heating circuit, stopping the leak is only part of it: the system may then need refilling, venting, pressure-testing and re-dosing with inhibitor, and where the work sits close to the boiler or gas pipework it becomes Gas Safe territory (more on that below). It’s also worth knowing that the plumbing repair stops the water — but drying out, electrical checks, flooring and making good are often separate jobs, frequently handled through an insurance claim.

Hard Thames Water supply is a background factor too: it leaves limescale on taps, valves, cylinders and appliances over time, which is a maintenance consideration and can shorten the life of some parts.² The bigger burst risk in older stock is simpler — pipework run through uninsulated lofts, voids and outside walls, exactly where it freezes. To prevent the next one, lag exposed pipes in those cold spots, keep a little background heat on during cold snaps, and if you’ll be away in winter, consider draining the system down.

Burst pipes in Camden’s flats, period homes and estates

In Camden, a burst is rarely just your problem. The borough is mostly flats, and ONS Census 2021 data shows private renting is the largest tenure.⁴ So a burst in one flat often shows up first in the ceiling of the flat below, water runs through shared risers and stacks, and stopping it can mean reaching a communal valve, a managing agent or a freeholder. In mansion blocks especially, the main stopcock may sit in a locked riser cupboard or basement with keys held by a caretaker or managing agent — so how fast a burst can be isolated often comes down to access, not plumbing. Knowing where your own stop tap is, before winter, is the single best preparation.

Much of Camden’s housing is older — Victorian and Edwardian terraces, mansion blocks and converted houses across Hampstead, Camden Town, Bloomsbury and beyond — with pipework run through uninsulated lofts, basements, voids and external walls. Those are exactly the cold spots where pipes freeze and then split as they thaw, which is why, in practice, period Camden homes tend to see more cold-snap bursts.

On Camden’s estates, a burst on a communal riser or primary pipe isn’t a private-plumber job. Shared pipework and communal heating and hot-water systems are the council’s or its contractor’s responsibility.⁶ If you’re a Camden Council tenant, Camden Council treats an uncontainable leak as an emergency, with an out-of-hours line on 020 7974 4444 between 6pm and 8am⁵ — though on some estates run by a Tenant Management Organisation, your first call may be to the TMO rather than the council. One thing worth ruling out in a basement or lower-ground flat: if water is welling up from the lowest drains during heavy rain rather than spreading from a pipe, that points to drainage, not a burst — see Blocked Drains.

Safety first

A burst pipe is mostly a water emergency, and the real danger is water meeting electricity. Thames Water advises that if water is near your electrics you should switch them off at the mains — and you should never touch switches, sockets or fittings that are wet.¹ If water is coming through a ceiling light or pooling above a ceiling, treat the whole circuit as live and keep clear — and remember a ceiling bulging with trapped water can collapse, so keep people out from underneath until it’s drained down safely.

Stopping the water at the stop tap removes the source; turning off the heating and opening the taps drains the system and relieves pressure on the burst.¹ If the burst is on a heating pipe or near the boiler, the gas side of a system is not general-plumber work: by law only a Gas Safe registered engineer may work on the boiler, gas pipework and the final connections to it.⁸

Separately, if you ever smell gas — while dealing with a burst or at any other time — treat it as a different emergency: don’t touch electrical switches, avoid naked flames and don’t smoke, open doors and windows if it’s safe, leave if the smell is strong or you feel unwell, and call the National Gas Emergency Service on 0800 111 999 from outside. Don’t go back in until a gas engineer has given the all-clear.⁷

Find a verified plumber for burst pipes by Camden district

Where you are in Camden changes where pipes freeze and who’s responsible when one bursts.

Hampstead, Frognal & Dartmouth Park (NW3 / NW5 edge). Large period houses with long pipe runs through cold lofts, basements and external walls — classic freeze-and-thaw territory, where a burst can run a long way before it shows. Conservation and listed-building status can mean temporary containment first, with permanent work to protected fabric arranged carefully.

Belsize Park, Swiss Cottage & South Hampstead (NW3 / NW6). Mansion blocks and converted flats, where a burst on a shared riser affects several homes at once and the communal stopcock and access often sit with a managing agent or caretaker.

Camden Town, Chalk Farm & Primrose Hill (NW1). Nineteenth-century terraces and flats above shops, where a burst above a commercial unit can damage both the business below and the home above, making every minute of delay more expensive.

Kentish Town & Gospel Oak (NW5). Converted houses and council estates side by side; on estate blocks a burst on a communal pipe is routed through the council, and the Gospel Oak heat network means some heating pipework is communal rather than yours.⁶

West Hampstead & Fortune Green (NW6). Period red-brick terraces and mansion blocks, much of it rented — so a winter burst often means looping in a landlord or letting agent as well as a plumber.

King’s Cross, St Pancras, Somers Town & Euston (N1C / NW1 / WC1H). New-build blocks and estates with communal systems — the Somers Town network heats hundreds of homes⁶ — so a heating or hot-water burst may sit on the network side, not yours.

Bloomsbury, Holborn, Fitzrovia & Covent Garden (WC1 / WC2 / W1 edge). Listed buildings, hotels and flats over commercial premises, where a burst can mean conservation-sensitive repairs and freeholder sign-off — and where a call-out may fall inside the central London Congestion Charge zone.¹⁰

What burst pipe repairs cost in Camden

Burst work is usually priced as an emergency call-out, sometimes outside normal hours. The ranges below are an editorial guide to help you sense-check a quote, not a fixed rate.

Editorial estimate only — these are not regulated rates, not market data and not a published cost survey. Prices vary widely by plumber, access, parts, time of day and the extent of water damage.

When you book, it’s worth confirming a few things up front: the call-out fee, whether you’re charged a fixed price or by the hour, any out-of-hours premium, whether VAT and parts are included, and whether the plumber carries common fittings. All of Camden is inside the Ultra Low Emission Zone, so a plumber in a non-compliant vehicle pays £12.50 a day to work in the borough,⁹ which can feed into call-out pricing. Central and southern Camden addresses — around Bloomsbury, Holborn, Covent Garden, Fitzrovia and some King’s Cross/Euston-edge streets — may also sit inside the central London Congestion Charge zone;¹⁰ check a specific address by postcode with TfL.

Frequently asked questions

Why verified plumbers — not a general directory

When a pipe bursts you call fast and you call once — there’s water coming down, and no time to cross-check reviews, insurance and registrations. That’s exactly why we do the checking in advance, so the shortlist you’re choosing from is already vetted.

Every plumber here is checked before going live and re-verified annually: we confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, we review the feedback they’ve earned across the web, and we confirm they cover Camden’s NW, N, WC and edge-of-W postcodes before a profile is approved. Where a burst involves the gas or boiler side of a heating system, we confirm registration directly with the Gas Safe Register⁸ and would tell you to ask to see the engineer’s Gas Safe ID card. For water-supply and fittings work, you can also check a plumber yourself on WaterSafe, the free, water-industry-backed national register.¹¹

Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. And there’s no customer middleman fee: enquiries go directly to the plumber.
