Burst Pipes in Hammersmith & Fulham

Q: A pipe's just burst — what do I do first?

Turn off the water at the internal stop tap (usually under the kitchen sink, turned clockwise), then turn off the heating and open all the taps to drain the system. Soak up water with towels, and switch off electrics at the mains if water is near them. Then call a plumber once it's contained.

A burst pipe floods fast, but many can be limited quickly at the stop tap — if you know where it is and it turns. Every plumber here is checked before listing, so once the water’s off you’re calling someone you can trust.

✅ Checked before listing — identity, insurance, trading presence, Gas Safe (where relevant). How we verify →
✅ Workmanship guarantee badges on listings — 1, 3, 6 or 12 months

⚠️ Water near electrics? Switch off at the consumer unit only if it’s dry and safe to reach — never touch wet wiring. If you also smell gas (for example if water has reached a boiler), leave and call the National Gas Emergency Service on 0800 111 999 from outside (free, 24 hours) before anything else.

Stopping a burst — the stop tap comes first

When a pipe bursts, every minute the water runs is more damage. The single most useful thing you can do is shut off the supply at the stop tap, then drain the system.

Thames Water sets out the sequence: find your internal stop tap — usually under the kitchen sink, though in flats and conversions it can be in a utility area, hall cupboard or riser — and turn it clockwise to stop the water. Then turn off the heating, open all the taps to drain the system quickly, and soak up escaping water with towels. If any water is near your electrics, switch them off at the mains.¹

If you can’t find the stop tap, or it won’t budge — common with old, rarely-used stopcocks in period homes — our guide on how to find your stop tap walks through the usual locations in London homes and what to do if it’s seized. In a flat or mansion block, isolation isn’t always inside your own home: it may be a shared valve in a landing riser cupboard or controlled by building management, so it’s worth knowing yours before you ever need it.

Once the water’s off and the area’s safe, that’s the moment to call a plumber — the emergency is contained, and you’re not paying while the flood continues. A first emergency visit will usually cap or isolate the burst and replace a short, accessible section to make the property safe; drying out, repairing access and making good are often a separate, later job.

Why pipes burst in Hammersmith & Fulham

Bursts aren’t random. In a borough like H&F, a handful of local factors explain most of them. The council’s Housing Strategy 2021–2026 records that around 73% of homes are flats, apartments or maisonettes, with the private rented sector the largest tenure — much of it in older, converted stock where the pipework tells a story.¹

Freeze-thaw on exposed runs. Thames Water explains that when water freezes it expands, cracking or splitting the pipe, and the leak often only shows on the thaw as water finds the damage.² The most vulnerable runs are the exposed ones — in unheated lofts, garages, alongside cold exterior walls and to outside taps. H&F’s many converted Victorian and Edwardian houses, where pipework was added to lofts and back additions over the years, are exactly the stock where those exposed runs turn up.

Hard water and ageing joints. The borough is in Thames Water’s hard-water region, where all the water is hard because it passes through chalky limestone.³ Scale, corrosion, pressure changes, movement and old past alterations can all leave older joints more vulnerable over time — so a “sudden” burst is often a long-weakened joint finally giving way. There’s more on hard water in our London hard water guide.

Old pipe materials. Thames Water notes that you’re unlikely to have lead pipes if your home was built after 1970, but older properties may still have a lead supply pipe or internal lead plumbing.⁴ Given how much of H&F’s housing is period stock, old lead and galvanised-iron pipework is a realistic find, and corroded supply pipes sometimes fail — making a burst the prompt to replace a length rather than just patch it. Our Victorian terrace plumbing guide covers the quirks of period stock in more depth.

Pressure on shared and riser pipework. In mansion blocks and converted houses split into flats, a burst on a shared riser or an old branch affects more than one home, which changes who needs to be told and who’s responsible — covered next.

Whose pipe is it — and who pays to fix it?

A burst raises an immediate ownership question, and the answer decides the bill. Thames Water sets the line clearly: as a homeowner, you’re responsible for the supply pipe running from your property boundary into your home — usually under your garden or driveway — and for all your internal pipes, appliances and fittings. Thames Water is responsible for the pipework from the boundary back to its main. Once a leak on your property is confirmed, Thames Water states it’s your legal responsibility to arrange repair within four weeks.⁵

Two H&F-specific wrinkles follow from that:

If you rent or it’s a council/leaseholder property. Thames Water says that if you’re a tenant, fixing leaks is your landlord’s responsibility — tell your landlord or letting agent as soon as possible, in writing.⁵ H&F is a heavily-rented, flat-led borough, so this comes up constantly. If you’re a council tenant or leaseholder, the council’s emergency repairs line is 0800 023 4499, available around the clock for emergencies, and the council is responsible for the building structure and communal pipework.⁶

If a shared supply pipe serves several homes. Thames Water notes that a single supply pipe sometimes serves more than one property — more common where buildings sit close together, as on H&F’s terraced streets and in converted houses.⁵ A burst on shared pipework is a conversation with neighbours, freeholder or managing agent before anyone books a private repair.

For property damage from a burst on the public mains, Thames Water’s contact line is 0800 316 9800.⁷

If water has crossed into another flat or a business below, take photos and a short video before any clean-up, keep the plumber’s notes and receipts, and notify your insurer — and the landlord, freeholder or managing agent where relevant — so any claim is properly evidenced.

Safety first

A burst pipe is usually a water emergency, but two hazards can turn it into something more serious.

Water and electricity. If water is coming through a ceiling light, near a consumer unit, or down a wall with sockets, switch off at the consumer unit only if it’s dry and safe to reach. Never touch anything electrical that’s already wet, and if in doubt, stay clear and get an electrician or the emergency services.

If you smell gas during or after a burst — for example if water has affected a boiler — treat gas as the priority and follow the National Gas Emergency Service’s steps:

Don’t switch anything electrical on or off, use no naked flame, don’t smoke — and keep mobile phones away from the suspected leak.
Open doors and windows if it’s safe to do so.
If you know where the gas meter control valve is and can reach it safely, turn off the gas at the meter — unless the meter is in a cellar.
Leave the property if the smell is strong or you feel unwell.
From outside, call the National Gas Emergency Service on 0800 111 999 — free, 24 hours.
Don’t go back in until a gas engineer says it’s safe.

The National Gas Emergency Service sets out this sequence and confirms the 0800 111 999 line runs 24 hours.⁸

Thawing a frozen pipe. If a pipe is frozen but not yet split, keep the stop tap off, warm it gently — never with a naked flame or blowtorch — and check it carefully as it thaws, because a split may only show once water starts moving again. If you’re not confident, a plumber can thaw and inspect it safely.

Gas work is Gas Safe work. If a burst has affected your boiler or its pipework, the gas boundary still applies. The HSE sets out that a non-registered person may do “wet work” — water pipes and radiators — but any work on the gas boiler itself, and the final connection of pipework to it, must be done by a Gas Safe registered engineer.⁹ We confirm a plumber’s registration directly with the Gas Safe Register before listing them for gas work.¹⁰

Find a verified emergency plumber by district

In a burst, the building type shapes where the water travels and who else is affected.

Hammersmith, Ravenscourt Park & Fulham Reach (W6) — older terraces and conversions off Goldhawk and Paddenswick Roads with pipework added to lofts and back additions over the years, exactly the exposed runs that freeze and split. Flats above shops on King Street mean a burst upstairs can quickly reach a business below.

Shepherd’s Bush, White City, Wood Lane & Wormholt (W12) — a mix of Victorian terraces, mansion blocks and large local-authority estates including the White City Estate. A burst on a shared riser in an estate block is a communal/council matter, not a private repair, so the council route often applies before anyone pays.

Fulham, Fulham Broadway, Parsons Green, Walham Green & Munster (SW6) — mansion blocks and purpose-built Victorian flats around Fulham Palace Road, with shared risers and old branch pipework where a single burst can drop water through several flats. Reaching the right neighbour and the managing agent fast matters as much as the fix.

Sands End, Imperial Wharf & the riverside (SW6) — riverside apartments and newer blocks with plant rooms, boosted cold-water systems and concierge-controlled isolation, where the managing agent or building manager usually needs to be involved before work starts.

West Kensington, Barons Court, Avonmore & North End (W14) — older flats, conversions and mansion blocks, plus the West Kensington and Gibbs Green estates. W14 is shared with Kensington & Chelsea, so check your plumber covers your side of the boundary.

Brook Green & Addison — conservation-sensitive terraces and mansion blocks with lower-ground spaces, where exposed and older pipework in period buildings is the usual burst risk.

What a burst-pipe call-out costs

Stopping a burst is usually quick; the full repair depends on access, pipe material and what’s been damaged. As a rough orientation only:

Burst-pipe job	Editorial estimate (guide only)
Stop the burst & make safe (first hour)	£120–£250
Repair or replace a burst section	£150–£400
Replace a length of corroded supply pipe	£400–£1,200+
Evening / weekend emergency call-out	£150–£300+
Thaw and check a frozen pipe	£100–£200

Editorial estimate only — these are general guide figures, NOT regulated rates, NOT market data and NOT a published cost survey. Always confirm the call-out fee before the plumber travels. Hammersmith & Fulham is inside London’s Ultra Low Emission Zone, so a non-compliant van may carry the £12.50 daily ULEZ charge.¹¹ The borough is outside the central London Congestion Charge zone, so that charge doesn’t normally apply to local callouts.¹² It’s also worth checking your home insurance — Thames Water advises confirming your policy covers damage from frozen or burst pipes. See the London plumbing costs & compliance guide for more.

Frequently asked questions

Turn off the water at the internal stop tap, usually under the kitchen sink, turned clockwise, then turn off the heating and open all the taps to drain the system.

Soak up water with towels, and switch off electrics at the mains if water is near them.

Then call a plumber once it’s contained.

Old stopcocks seize from years of not being used.

If yours won’t turn, don’t force it hard enough to snap it.

In a flat or block there may be a shared isolation valve in a riser cupboard or with building management.

Our stop tap guide covers the usual spots; in the meantime, a plumber can isolate at another point.

When water freezes it expands and cracks the pipe, but the crack may not leak until the ice melts and water flows through the damage — which is why bursts often appear as the weather warms after a cold snap.

You’re responsible for the supply pipe from your boundary into your home and for all internal pipework; Thames Water is responsible from the boundary back to the main.

If you rent, it’s your landlord’s responsibility — and if you’re a council tenant or leaseholder, use H&F’s repair route rather than paying privately.

Why verified plumbers — not a general directory

A burst pipe is a pressure situation — water spreading, a clock running — and that pressure is exactly what pushes people to call the first number they find. It’s the worst moment to discover the “plumber” you hired isn’t insured or isn’t who they claimed to be.

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 for evidence of public liability insurance — which matters enormously when water damage runs into other flats — and we confirm the plumber covers H&F’s W6, W12, SW6 and W14 postcodes before a profile is approved. Where a burst involves a boiler or gas pipework, we confirm Gas Safe registration directly with the Gas Safe Register, and you can ask to see the engineer’s Gas Safe ID card. For water-supply and fittings work, you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register.
