Do this first — before the plumber arrives
Royal Borough of Greenwich states that emergency housing repairs include situations that could cause danger or serious property damage, with response targets for council tenants.¹ For any burst pipe, act on these three steps now.
Step 1 — Turn off your stopcock. This isolates the water supply and stops the flow. In most Greenwich properties the stopcock is under the kitchen sink. In Victorian terraces across Charlton, Plumstead and Eltham it may be under the stairs, in the hall, or in a cupboard near the front door.
If it will not turn — common in older or infrequently used valves — do not force it. The external stop valve sits beneath a small metal cover in the pavement outside your property; your plumber or Thames Water can locate and operate it.
Step 2 — Isolate electrics near the water. Water and live electrics are the most dangerous combination in a flood situation. If water is near any electrical fittings, switches or consumer units, isolate the circuit at the fuse board — if safe to do so.
Step 3 — Call a plumber and notify your insurer. Call before the damage spreads further. Photograph the burst pipe and all visible damage — but do not wait to start emergency containment or mopping up. Insurers commonly expect policyholders to take reasonable steps to limit further damage, so don’t delay containment to wait for instructions. Keep the failed section of pipe as evidence.
💡 Pro tip: After the burst has been contained and your stopcock is isolated, check your water meter. If the dial is still moving, the stopcock may not be fully sealing or there could be a second burst point elsewhere in the system. Continued movement may indicate ongoing flow somewhere in the system — confirm with your plumber before they leave.
What causes burst pipes in Greenwich properties
Burst pipes in Greenwich follow three distinct patterns.
Frozen pipes are a common cause of burst pipes during cold weather. When water freezes inside a pipe it expands — copper or lead pipe that cannot flex splits. The burst does not always happen when the pipe freezes; it often happens when the ice thaws and pressure releases suddenly. Uninsulated loft pipework is more vulnerable during freezing weather, particularly in older terraced houses where it runs through unheated voids.
Corrosion and joint failure are also common issues in older pre-1914 terrace housing. Thames Water says most water supplied across London and the South East is hard.² Hard water contributes to limescale build-up within plumbing systems and appliances over time. Older lead supply pipes may be more susceptible to leaks and deterioration over time, particularly in pre-1914 properties that have never had their supply pipe replaced.
Ground movement is the third cause. Parts of Greenwich sit on London clay — a soil type that shrinks in dry summers and swells in wet winters. That movement can stress buried supply pipes over time. Note that geology varies across the borough — Thamesmead in particular is on reclaimed and alluvial ground rather than London clay, while higher ground around Shooters Hill differs again. A pipe stressed by ground movement over years may burst at a joint with no warning.
Why Greenwich properties carry higher burst pipe risk
Three factors compound the risk in Greenwich specifically. Hard water contributes to limescale build-up inside plumbing systems over time, which can restrict flow. The Victorian terrace stock across Charlton, Woolwich and Plumstead carries pipe runs through suspended timber floors, solid brick walls and unheated roof spaces — locations that are both difficult to insulate properly and difficult to access when a burst occurs.
Uninsulated loft pipework in older terraces can be particularly vulnerable during sustained cold weather. Ground movement on London clay can put buried supply pipes under cyclic stress over time, which is why ground-movement bursts in older properties can occur without prior warning.
What to expect from a burst pipe repair visit
A plumber attending a burst pipe works in two phases.
Phase one — containment. Confirm the stopcock is isolated, assess the damage, locate the burst, and make the pipe safe. If the burst is in an accessible location — under a sink, in an airing cupboard, along an exposed pipe run — containment and temporary repair can happen within the first hour. If it is within a wall, under a floor or in a roof space, the plumber confirms isolation is holding and assesses the access required before proceeding.
Phase two — repair. The split or failed section is cut out and replaced. Copper-to-copper joints are soldered or compression-fitted. Where a burst reveals lead supply pipework, Thames Water operates a lead pipe replacement scheme — if you replace your internal supply pipe, Thames Water may replace the communication pipe on their side of your property boundary at no additional cost.⁴ Ask your plumber to assess the full supply pipe condition and whether you qualify.
After any burst pipe repair, ask your plumber to check insulation on all other exposed pipe runs in the same area — particularly loft spaces and under suspended floors. A burst in one location is often a sign that adjacent runs are under identical stress.
Burst pipes and your home insurance
Escape of water — the insurance term for burst pipe damage — is one of the most common types of domestic property damage claims. The ABI states that insurers pay out £1.8 million a day for escape of water claims.³
What your policy typically covers: damage to the building fabric caused by escaped water — floors, walls, ceilings, plasterwork. What it typically does not cover: the cost of repairing the pipe itself, or damage resulting from pre-existing wear and lack of maintenance.
To protect your claim: act immediately to mitigate the damage, photograph everything before any repair begins, notify your insurer before commissioning work beyond emergency containment, and keep all invoices. Ask your plumber for invoices, photos and written reports that can support an insurance claim.
What burst pipe repair costs in Greenwich — 2026
Typical London 2026 ranges. Actual costs vary by pipe location, access and materials. No official pricing data exists for private burst pipe repair — always obtain written confirmation before any work beyond emergency containment begins.
| Service | Typical London range 2026 |
|---|---|
| Emergency callout (attendance + initial assessment) | £120–£180 |
| Straightforward burst repair (accessible pipe, all-in) | £260–£320 |
| Burst within wall or floor (access required) | £300–£600+ |
| Lead pipe section replacement | £200–£400 per section |
| Full lead mains replacement | £1,500–£3,500 |
Customers should request written confirmation of pricing before work beyond emergency containment begins. If access work is required, this is quoted and agreed separately before any opening up begins.
Frequently asked questions — Burst Pipes Greenwich
Three things immediately. Turn off the stopcock — usually under the kitchen sink, or under the stairs in older Greenwich terraces. Isolate any electrical circuits near the water if safe to do so. Then call a plumber.
Start mopping up immediately — insurers commonly expect policyholders to take reasonable steps to limit further damage. Photograph all visible damage and keep the failed section of pipe as evidence for your insurer.
In most Greenwich properties it is under the kitchen sink. In Victorian terraces across Charlton, Plumstead and Eltham it is often under the stairs, in the hall cupboard, or near the front door.
If you cannot find it or it will not turn, there is an external stop valve in the pavement directly outside your property — your plumber can locate and operate it.
Insulate exposed pipe runs in loft spaces and under suspended floors before winter sets in. Keep background heating on during freezing periods, particularly in unoccupied properties.
Know where your stopcock is before an emergency, and test it annually — older stopcocks that have not been operated for years can become stiff or seized over time. If your property has a history of frozen pipes, ask your plumber to lag the specific runs that have previously failed.
Older lead supply pipes may be more susceptible to deterioration over time than modern replacement pipework. Thames Water operates a lead pipe replacement scheme — if you replace your internal supply pipe, Thames Water may replace their communication pipe at no additional cost to you.⁴
If your plumber identifies lead pipework during a burst pipe repair, ask for a full assessment of the supply pipe condition and whether you qualify for the scheme.
The damage caused by the burst — to floors, walls, ceilings and plasterwork — is typically covered under escape of water on a buildings insurance policy. The cost of repairing the pipe itself is generally not covered.
Damage resulting from pre-existing wear or lack of maintenance may be excluded. Act immediately to mitigate the damage, notify your insurer promptly, and keep all documentation.³
