What counts as a plumbing emergency — and the first five minutes

Not every plumbing problem is an emergency, and not every emergency is a private-plumber job. A genuine emergency is something causing damage now or that can’t safely wait: an active leak or burst you can’t stop, no water at all, sewage backing up into the property, no heat in cold weather, or anything where water is near electrics. A dripping tap, a slow-draining sink or a single cold radiator can usually wait for a booked visit — and you’ll often pay less for it.

If something’s actively leaking, the first move is almost always the same: find your stop tap and turn the water off. Most London homes have an internal stop tap under or near the kitchen sink and an outside stopcock near the boundary; our guide on how to find your stop tap walks through both. If water is anywhere near electrics or light fittings, treat it as dangerous, keep clear, and isolate the power only if you can do so safely. Then contain what you can, move what’s below the leak, and photograph the damage for any insurance claim before you start mopping up.

Before you call a private plumber, it’s worth knowing who actually owns the problem — because some emergencies aren’t yours to fix and aren’t chargeable to you:

• Gas smell or suspected carbon monoxide → the National Gas Emergency Service on 0800 111 999, not a plumber.¹ More below.
• A blocked or overflowing public sewer → Thames Water, which is responsible for public sewers and reachable 24 hours on 0800 316 9800.⁵ A blockage is more likely the public sewer’s if neighbouring properties are affected too, or if it sits beyond your boundary.
• A burst water main or leak in the street → Thames Water, on its 24-hour leak line 0800 714 614.¹⁴ Thames Water is responsible for the main up to your property boundary.
• A Camden Council home → Camden Council handles emergency repairs, with an out-of-hours line on 020 7974 4444 between 6pm and 8am.⁷

For everything else — the bursts, leaks and blockages inside your own property — a verified emergency plumber is the right call.

Emergencies in Camden flats, basements and estates

Camden is mostly a borough of flats, and the largest group of residents rent rather than own — ONS Census 2021 data shows private renting is the borough’s biggest tenure.⁹ In an emergency that changes things: a leak in one flat is often first noticed in the flat below, water tracks through shared risers and stacks, and reaching a stopcock or a communal valve out of hours can mean involving a managing agent or freeholder. Knowing where your own internal stop tap is — before anything goes wrong — saves the most time.

Basements and lower-ground flats, common across Camden, carry an extra risk. Camden Council says most of the borough’s sewers are combined sewers, and in heavy rain they can surcharge and force water back up through the lowest fixtures.⁸ That’s a different emergency from a burst pipe — the longer-term fix is a non-return valve or pumped drainage, not just a clear-out — so it’s worth establishing early whether water is coming from your own pipework or backing up from the sewer.

Two more Camden patterns shape emergency calls. Hard Thames Water supply⁶ means limescale shortens the life of valves, flexible hoses, fill valves and cylinders, so sudden failures often trace back to scale. And “no heat” isn’t always your boiler: on estates served by communal or district heating,¹⁰ the heat source is shared, and an outage may be a network or plant fault for the council or its contractor — not something a private plumber can fix on your side of the wall.

Safety first

Some emergencies are about safety before plumbing. If you smell gas, or suspect a gas leak:

1. Don’t touch anything electrical — no switches on or off — and no naked flames, smoking or using a mobile near the suspected leak.
2. Open doors and windows if it’s safe to do so.
3. If you know where the gas 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.¹
6. Don’t go back in until a gas engineer has given the all-clear.

Carbon monoxide is the silent danger. It has no smell, and UK government guidance lists headaches, dizziness, nausea, tiredness and breathlessness as common symptoms — often mistaken for flu, with a strong clue being that they ease when you leave the house.² Warning signs on an appliance include soot or staining, a lazy yellow or orange flame instead of a crisp blue one, and a pilot light that keeps blowing out.¹ If you suspect carbon monoxide, treat it like a gas emergency: stop using the appliance, open doors and windows, get everyone out, and call the National Gas Emergency Service on 0800 111 999. Then seek medical help straight away — National Gas warns that going outside into fresh air won’t treat carbon monoxide exposure on its own, and you may not realise how badly you’ve been affected.¹

Two things protect you between emergencies. First, every home with a fuel-burning appliance should have an audible carbon monoxide alarm that complies with BS EN 50291, sited in line with the manufacturer’s instructions — not just “near the boiler.”² In rented homes this is a legal duty: under the Smoke and Carbon Monoxide Alarm (England) Regulations 2015, as amended in 2022, landlords must fit a CO alarm in any room used as living accommodation that contains a fixed combustion appliance, other than a gas cooker.³ Second, gas work is not DIY and not general-plumber work: by law only a Gas Safe registered engineer may work on gas appliances, boilers, flues and gas pipework,⁴ so always ask to see the engineer’s Gas Safe ID card and check it covers the specific job.

Find a verified emergency plumber by Camden district

Where you are in Camden changes what an emergency looks like and how quickly it can be reached.

Camden Town, Chalk Farm & Primrose Hill (NW1). Flats above shops and busy one-way streets around Camden High Street, Parkway and Kentish Town Road mean access and parking can slow a call-out, and a leak above a commercial unit raises the stakes. Chalk Farm sits at the foot of Haverstock Hill and Adelaide Road, where Camden’s flood investigation recorded surface-water build-up in heavy rain.⁸

Kentish Town & Gospel Oak (NW5). Converted houses and council estates sit side by side. The Maitland Park / Queen’s Crescent area was a named 2021 flood hotspot,⁸ and because the Gospel Oak heat network supplies many homes,¹⁰ a “no heat” emergency here may be a communal fault routed through the council, not a private boiler call.

Hampstead, Frognal & Dartmouth Park (NW3 / NW5 edge). Older houses with concealed pipework and basement conversions, where a hidden leak can run a long way before it shows. Dartmouth Park’s steep roads and the Hampstead Heath edge were both 2021 flood hotspots,⁸ and listed-building status can complicate emergency repairs that touch protected fabric.

Belsize Park, Swiss Cottage & South Hampstead (NW3 / NW6). Mansion blocks and converted flats mean a burst often involves the flat below and a managing agent’s say-so on access. The South Hampstead/Kingsgate streets — Goldhurst Terrace, Fairhazel Gardens, Priory Road — saw basement and underground-car-park flooding in 2021.⁸

West Hampstead & Fortune Green (NW6). Period terraces and mansion blocks along and around West End Lane, much of it rented — so an out-of-hours emergency 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 homes,¹⁰ so the first question on a heating or hot-water emergency is whether it’s your system or the network’s.

Bloomsbury, Holborn, Fitzrovia & Covent Garden (WC1 / WC2 / W1 edge). Listed buildings, hotels and flats over commercial premises, where access and freeholder sign-off matter even in an emergency — and where a call-out may also fall inside the central London Congestion Charge zone.¹²

What emergency plumbing costs in Camden

Emergency work is priced differently from booked work: you’re paying for speed, often 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. Emergency and out-of-hours pricing varies widely by plumber, time of day, parts and how long the job takes.

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,¹¹ 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;¹² check a specific address by postcode with TfL. For a fuller breakdown, see our London plumbing costs guide.

Frequently asked questions

Why verified plumbers — not a general directory

An emergency is the worst possible time to vet anyone. Water’s coming through the ceiling, you grab the first number that looks legitimate, and you’ve no easy way to tell a properly insured local plumber from a call-centre lead-seller charging a premium to send whoever’s free. That’s the exact gap this directory closes.

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 job involves gas, we confirm registration directly with the Gas Safe Register⁴ — and in an emergency we’d still 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.¹³

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, even at 2am.
