Every listing is verified at time of listing — Gas Safe registration checked against the Gas Safe Register where applicable, evidence of public liability insurance checked, business identity and named contact validated.
Emergency callouts typically cost more than standard appointments, especially out-of-hours. Some emergency visits may be make-safe only (isolate, cap, contain) with full repair booked after. No call centres, no middlemen — you contact the engineer directly, describe the location and severity (and whether water is near electrics), and confirm timing and price before they attend.
Before any engineer begins gas work, ask to see their Gas Safe ID card and check the back of the card for the specific work categories they are qualified to carry out.

Understanding burst pipe repair in Croydon
First actions — stop the water, protect the property
The priority with a burst pipe is stopping the flow before damage escalates.
The internal stop tap is usually located under the kitchen sink. In older Croydon properties — particularly Victorian and Edwardian terraces in Thornton Heath, South Norwood, Norbury and Addiscombe — stop taps can be in awkward locations (under the stairs, in a cellar, in a downstairs toilet). Find yours now, before you need it.
If you cannot locate or operate the internal stop tap and water is flowing, there is often an external stop valve outside the property — typically a small metal cover on the pavement or front path. You can turn this off with a stop tap key, available from hardware shops. Thames Water advises that the inside stop valve should be used first and that the outside stop valve should only be used in an emergency — and where a supply is shared with neighbouring properties, turning off the outside valve may affect their water too.³
Frozen pipes and winter bursts
Most burst pipes in London happen in winter, when water in the pipe freezes, expands and splits the pipework. The burst is often only discovered when the pipe thaws and water starts to flow.
If you hear water running when no taps are on, see a damp patch appear after a cold snap, or notice water pressure suddenly drop, a frozen or burst pipe is likely. Turn off the stop tap and call an engineer.
Suspected carbon monoxide poisoning — what to do
A burst pipe can affect a gas boiler if water reaches it — and damp combustion environments raise CO risk. Carbon monoxide is colourless and odourless. Symptoms include severe headache, dizziness, nausea, confusion, breathlessness and loss of consciousness. If you suspect CO poisoning:
- Leave the property and get into fresh air
- For severe symptoms (loss of consciousness, breathlessness, sudden confusion) → call 999 for an ambulance
- For less severe symptoms or advice → call NHS 111
- Also call 0800 111 999 (National Gas Emergency Service, 24/7) to report the appliance
- Do not re-enter the property until cleared by the gas emergency service

Responsibility for a burst pipe depends on where it is — and which water company supplies clean water to your specific Croydon address.
Internal plumbing and the supply pipe within your property boundary: your responsibility. Thames Water confirms that homeowners are responsible for the water supply pipe running from the property boundary into the home, as well as all internal pipes, appliances and fittings.³ SES Water states the same principle for SES-supplied premises.⁷
Pipes in the road or pavement outside your boundary: the water company’s responsibility — but which company depends on your postcode. Clean-water supply across Croydon is split between Thames Water and SES Water (Sutton & East Surrey) — SES Water serves parts of South Croydon, Thames Water serves most of the rest. Report:
- Thames Water-supplied areas: call 0800 316 9800.³
- SES Water-supplied areas (parts of South Croydon): call 01737 772000 24/7 for emergencies — immediate risk to health/safety, property damage or environmental threat.⁷
Confirm your supplier via your water bill or SES Water’s postcode area page before reporting. Sewerage and public sewer responsibility across all Croydon postcodes sits with Thames Water regardless of clean-water supplier.
Tenants: report to your landlord or letting agent first — bursts on landlord-provided pipework are the landlord’s responsibility to repair.³
Council tenants in Croydon — burst pipe repair route
If you live in a Croydon Council home, burst pipe repairs go through the council, not a private engineer.
Call 020 8726 6101 — the contact centre operates 24 hours a day, 365 days a year for emergency repairs.⁴
Private tenants in Croydon — landlord obligations
A burst pipe is an urgent disrepair issue for any rented property. Contact your landlord or letting agent by phone immediately and follow up in writing.
If your landlord does not respond or gives an unreasonable response, contact Croydon Council’s Private Sector Housing Team on 020 8760 5476. The council uses the Housing Health and Safety Rating System to assess the hazards and risks in your home and, if they are serious, may be able to take action to get the landlord to complete work.⁵ Broader landlord repair duties for installations for water, gas, electricity, sanitation, space heating and heating water sit under Section 11 of the Landlord and Tenant Act 1985.⁸
In the meantime, you can still turn off the stop tap yourself to limit damage — that doesn’t affect your tenancy rights or your landlord’s repair duty.
Keep photographs, texts and emails — the council will ask to see evidence of what you reported and how your landlord responded.⁵
Hard water and burst-pipe risk in Croydon postcodes
Clean-water supply across Croydon is split between Thames Water (most of the borough) and SES Water (parts of South Croydon). Both supply areas are classified as hard water — Thames Water confirms hard water can lead to limescale build-up on household appliances and fittings.⁶ SES Water’s supply area in the Surrey/south London corridor is similarly hard.
Over time, scale and internal corrosion can contribute to wear in fittings, tap washers, and connection points on appliances — pinhole leaks and small bursts on old connections are a recurring issue across Croydon’s older housing stock. If a pipe that’s burst was clearly old, corroded or heavily scaled, replacement (rather than just patch repair) may be the more durable fix.
Croydon housing stock — practical context for burst pipe repair
The practical context of a burst pipe repair varies significantly across Croydon’s diverse housing stock. The notes below are general observations to help frame a call to an engineer — your engineer’s site visit will confirm what your specific property actually has.
Victorian and Edwardian terraces — Thornton Heath CR7, South Norwood SE25, Norbury SW16, Addiscombe CR0 (parts), West Croydon CR0. Internal stop taps are commonly under the kitchen sink but can be under the stairs, in a cellar, or in a downstairs toilet. Pre-1970 stock may retain lead service pipes from the boundary into the property — if a pipe burst is in a lead section, replacement to copper or MDPE is usually the longer-term fix. Older copper pipework on patched and replaced sections can have multiple compression joints that are common failure points.
Inter-war semis — Purley CR8, Coulsdon CR5, Sanderstead CR2, Shirley CR0 (parts), Selsdon CR2. 1920s-1930s semi stock typically has externally-accessible stop valves on driveways or front paths. Supply pipes can run under driveways where bursts may be hidden until water emerges through a path crack. Lofts and garages are often where pipes freeze in winter — most older Croydon bursts trace back to inadequate lagging on loft tanks, header tanks or pipes serving outside taps.
Post-war estates and 1960s-70s council stock — Selhurst SE25, New Addington CR0, Broad Green CR0, parts of Thornton Heath CR7. Concrete construction can make pipe-runs harder to access for repair; concealed pipework in chases through breeze block can require chasing out to reach the burst. Council tenants in this stock should call the council 020 8726 6101 line first rather than a private engineer.
Modern flats and high-rise — East Croydon CR0, Croydon town centre CR0, Old Town CR0 redevelopment zones. Purpose-built flats typically have planned plumbing risers and isolated branch supplies. Confirm with the building’s managing agent whether building-wide isolation is needed before extensive repair work — and whether you’re permitted to instruct a private engineer or have to use a building-appointed contractor.
Outer Croydon and semi-rural fringes — Coulsdon CR5, Old Coulsdon CR5, Kenley CR8, Whyteleafe CR3 (where bordering Croydon). Detached and substantial semi-detached properties often have longer external supply-pipe runs. Bursts in these supply runs can be slow to surface and may show as boggy patches in lawns or driveways before pressure-drop is noticed.
Shrink-swell clay context across Croydon. The British Geological Survey notes that clay shrink-swell can affect building foundations, pipes or services⁹ — particularly relevant in Croydon’s clay-heavy soils. Underground supply-pipe failures and recurring leaks on the same line can sometimes trace back to ground movement rather than the pipe itself. Worth raising with the engineer if a previous repair on the same line has failed.
Will home insurance cover a burst pipe?
Most home building and contents insurance policies include cover for escape of water — but the terms vary, particularly around:
- gradual leaks vs sudden bursts
- damage caused by frozen pipes where reasonable steps weren’t taken (e.g. leaving heating off while away in winter)
- damage to the pipe itself vs damage caused by the water
Check your policy before the engineer attends, and photograph the damage (pipe, water, affected surfaces, contents) for your claim. Thames Water also advises checking your home insurance for cover on leaks and bursts.¹
If you’re submitting an insurance claim, ask the engineer for a written report of the cause and scope of the damage.

Frequently asked questions — Burst Pipes Croydon
Turn off the water at the main stop tap (usually under the kitchen sink, turn clockwise), turn off the heating and boiler, and open all taps to drain the system.¹ If water is near electrical fittings or sockets, switch off the electrics at the mains.¹
Then call an engineer. Don’t wait — water damage escalates fast.
Usually under the kitchen sink. In older properties (Victorian and Edwardian terraces in Thornton Heath, South Norwood, Norbury and Addiscombe), it may be under the stairs, in a cellar or in a downstairs toilet.
There’s also an external stop valve outside most properties — a small metal cover on the pavement or front path, operated with a stop tap key. Find yours now, before you need it.
Call Croydon Council’s repairs line on 020 8726 6101. The contact centre operates 24 hours a day, 365 days a year for emergency repairs.⁴
Before help arrives, turn off the stop tap yourself to limit damage.
Most home insurance policies include cover for escape of water, but terms vary. Check your policy, photograph the damage, and ask the engineer for a written report of the cause and scope if you’re claiming.¹
Thames Water advises lagging exposed pipes with foam insulation, particularly in lofts, garages, and near outside taps or cold exterior walls.¹ Keep heating on at a low setting during cold snaps, and if you’re going away in winter, consider leaving the heating on a frost-protection schedule.
