⚠️ Smell gas, or feel dizzy and sick indoors? Don’t call a plumber first. Avoid switches and naked flames, open doors and windows, turn the gas off at the meter if it’s safe to reach (not in a cellar), leave if the smell is strong or you feel unwell, and call the National Gas Emergency Service on 0800 111 999 from outside (free, 24 hours).

What counts as a plumbing emergency in Kensington & Chelsea — and what can wait

A real emergency is anything you can’t stop or that’s actively causing damage or danger: water you can’t shut off, water reaching light fittings or sockets, no water at all, sewage coming back up into the property, or no heat and hot water in genuinely cold weather (especially with young children, older or unwell people in the home). A dripping tap, a slow-draining sink, a running toilet or a dribbling overflow are all worth fixing — but they’re bookable jobs, not 2am call-outs.

Make it safe before anyone arrives. For most water emergencies the single most useful thing you can do is turn off the stop tap — our guide to finding your stop tap shows where it usually hides in London homes. If it’s one fitting, isolate it at its own valve instead. If water is anywhere near electrics, don’t touch it — switch the power off at the consumer unit only if it’s safe to reach. Bear in mind a true emergency call-out is often a make-safe visit — capping, isolating or draining down to stop the damage — with the permanent repair quoted and booked separately.

No water at all? Before paying anyone, do Thames Water’s quick check: the mains usually enters at the cold kitchen tap, so Thames Water says if water comes from that tap but nowhere else, the problem is your internal plumbing (check the inside stop valve is fully open), whereas if neighbours have lost supply too it’s likely their network.¹ In a block of flats it’s also worth asking building maintenance or the managing agent about a known building issue before calling a plumber out. If it’s sewage or a drain backing up rather than clean water, that’s the blocked drains lane — and it may be the sewer, not you (see below).

When an emergency in Kensington & Chelsea isn’t a plumber’s job

Some of the most stressful “emergencies” here aren’t private plumbing at all, and paying a plumber won’t fix them.

Drains and sewers. RBKC states that foul and surface sewers are generally combined in Kensington and Chelsea,² so in heavy rain a basement or lower-ground flat can see drains back up — a real emergency, but often a public-sewer one. Thames Water says it owns and maintains the public sewers and shared sewers and lateral drains, with the owner responsible for the pipework inside their own boundary.³ RBKC advises reporting flooding from toilets, sinks, drains or a sewer manhole to Thames Water on 0800 316 9800 (24-hour), and a blocked road gully to the Council’s Streetline on 020 7361 3001.⁴ In a lower-ground flat, a failed pump chamber or a stuck non-return valve can turn heavy rain into a sewage backup, so the response may involve Thames Water, drainage equipment and a follow-up repair rather than a single visit.

Council-managed homes. If you rent from the Council, RBKC asks tenants to report repairs to Housing Management on 0800 137 111, rather than arranging a private plumber.⁵

Mansion blocks and managed buildings. When water comes through a ceiling, it may be from the flat above, a communal riser or a shared stack — so the first job is to isolate safely and confirm who controls the pipe (often the managing agent, freeholder, or a porter who holds keys to the communal stop valves) before anyone cuts into finishes.

Heating in winter. Thames Water confirms its region-wide water is hard, and scale can contribute to boiler and heating problems.⁶ But in parts of North Kensington and Notting Dale a “no heat or hot water” emergency may be a communal heat-network issue, not your boiler at all — so it’s worth checking whether neighbours have lost heat too before paying for a private boiler call-out.

Getting to you. The whole borough is inside the London ULEZ,⁷ and RBKC says there are no uncontrolled parking areas anywhere in the borough⁸ — both can shape how quickly, and at what cost, an emergency plumber reaches a central address.

Safety first

If you smell gas or suspect a leak, the National Gas Emergency Service sets out the steps:⁹

1. Don’t touch electrical switches, use no naked flames and don’t smoke — and keep mobile phones away from the suspected leak.
2. Open doors and windows if it’s safe to do so.
3. If you know where the meter control valve is and can reach it safely, turn the gas off there (unless the meter is in a cellar).
4. Leave the property if the smell is strong or you feel unwell.
5. Call the National Gas Emergency Service on 0800 111 999 from outside, and don’t go back in until a gas engineer says it’s safe.

Carbon monoxide. CO is colourless, odourless and tasteless. The HSE says around seven people a year die from CO poisoning from gas appliances and flues that weren’t properly installed, maintained or ventilated, and that any poorly-burning combustion appliance — not only a boiler — can produce it.¹⁰ Warning signs on an appliance include yellow or orange flames instead of crisp blue, soot or staining around it, pilot lights that keep blowing out, and more condensation than usual. Symptoms to watch for are headaches, dizziness, nausea, breathlessness, tiredness and chest or stomach pain — easily mistaken for flu, with the tell-tale being symptoms that ease when you leave the building. If you suspect CO, get into fresh air, call 0800 111 999 and seek medical help; the HSE Gas Safety Advice Line is 0800 300 363.

Only Gas Safe for gas work. Only a Gas Safe registered engineer may legally work on gas appliances, boilers, pipework or flues — and being registered isn’t the whole story, so ask to see the engineer’s Gas Safe ID card and check it covers the specific work.¹¹

Renting? Your landlord must arrange an annual gas safety check by a Gas Safe engineer on the appliances and flues they provide, and give you the Gas Safety Record within 28 days (still often called a CP12).¹² The HSE confirms the record must be kept for two years and given to new tenants before they move in.¹³

CO alarms. Under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 (SI 2022/707), in force from 1 October 2022, a CO alarm must be fitted in any room used as living accommodation that contains a fixed combustion appliance, excluding gas cookers, in rented homes.¹⁴ Government guidance recommends an alarm that complies with BS EN 50291, fitted in line with the manufacturer’s instructions. (Owner-occupier duties differ — this requirement is on landlords of rented homes.)

Find a verified emergency plumber by district

What an emergency tends to look like across the borough’s main areas:

• Chelsea & World’s End (SW3, SW10): lower-ground and riverside flats near Chelsea Embankment where a burst or a back-up reaches the basement first; on the World’s End and Cremorne estates, council-managed repairs route through RBKC rather than a private call-out.
• Kensington & Holland Park (W8, W14 edge): listed and conservation stock where making it safe and stopping the water matters most before anyone cuts into protected fabric; mansion flats often need managing-agent access to a communal riser to get at the source.
• Notting Hill & Ladbroke Grove (W11, W10): with sewers generally combined and many basement flats around Portobello Road and Ladbroke Grove, heavy-rain drain back-ups are a genuine emergency type here, not just clean-water bursts.
• North Kensington & Notting Dale (W10): estate blocks and the Notting Dale Heat Network mean a winter “no heat or hot water” emergency may be communal infrastructure, not a private boiler — worth checking before a call-out.
• South Kensington & Earl’s Court (SW7, SW5): mansion blocks, hotels and converted houses around Cromwell Road and Earl’s Court Road with communal risers and boosted systems, where one leak can travel between units and a hotel or restaurant has guest facilities and trading time at stake.
• Brompton (SW3, SW7): dense mansion-flat blocks along the Brompton Road / Old Brompton Road corridor, where a leak high in a shared riser can show several floors down — so isolating the right communal pipe, not just the visibly wet flat, is the first move.

What it costs

There’s no official price list for emergency plumbing, and we don’t publish invented “average” call-out rates. What’s honest is to set out what drives the cost — and emergencies cost more than booked visits for real reasons.

These are general cost factors, not regulated rates, not market data and not a published cost survey. In an emergency, agree a call-out charge before the plumber sets off, and get a fixed quote for the repair rather than an open-ended estimate — our How to Read a Plumbing Quote guide and London Plumbing Costs guide explain what to check.

Frequently asked questions

Why verified plumbers — not a general directory

In an emergency you call the first number you find — which is exactly the moment an unchecked trader can do the most damage, and overcharge for it. That’s why every listing here is checked before it goes live and re-verified, rather than simply accepted.

We confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, we review feedback and reputation from around the web, and we confirm the plumber covers Kensington & Chelsea’s W8, W10, W11, W14, SW3, SW5, SW7 and SW10 postcodes before a profile is approved. Because an emergency can turn out to be gas, we confirm Gas Safe registration directly with the Gas Safe Register where it applies — and you should still ask to see the engineer’s Gas Safe ID card. For work on your water supply and fittings, you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register.

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.
