Do these three things right now
1. Turn off the water at the mains stopcock
Turn it clockwise until it stops. In most London properties the internal stopcock is under the kitchen sink. In Victorian terraces it may be under the stairs, in a built-in cupboard near the front door, or in a boxed void near the party wall.
If the stopcock is seized and won’t turn — common in London’s older housing stock — go straight to the external stopcock in the pavement outside the property under a small metal cover marked “water.” Call Thames Water on 0800 316 9800 if you cannot isolate the supply and flooding is serious.
2. Turn off the electricity if water is near electrics
If water is near a consumer unit, sockets, light fittings or any electrical equipment, switch off at the consumer unit immediately.
Do not touch electrical fittings with wet hands. If in doubt, isolate the whole property at the main switch and do not restore power until the area is dry and inspected.
3. Call a verified local plumber
Find your borough in the grid below. Contact 2–3 plumbers simultaneously to compare availability and confirm arrival time before committing.
Take photos immediately for your insurer — before any drying or reinstatement work starts. Every plumber listed here is verified before listing, not after a job goes wrong.
Why burst pipes happen more in London than elsewhere
London clay and ground movement
London sits on one of the most reactive clay soil deposits in the UK. Clay shrinks significantly during dry summers and swells during wet winters — stressing buried supply pipes under gardens, external walls and driveways continuously.
The sequence of a prolonged dry period followed by heavy rainfall is consistently associated with an increase in burst pipe callouts across inner south and east London boroughs. Pipes that have been under clay movement stress for decades fail at their weakest point — typically at joints, bends or corroded sections.¹
Victorian and Edwardian pipework
A large share of London’s housing stock was built before 1914. These properties contain original lead supply pipes, early copper runs with soldered joints, and compression fittings that have been under mains pressure for over a century.
Lead pipe in particular becomes brittle with age and fails without warning. If your property was built before 1970 and has not had its supply pipework replaced, there is a reasonable probability that some lead pipe remains — particularly in the section running from the pavement to the property.
See our Victorian Terrace Plumbing Guide for what these properties typically contain.
Hard water and joint corrosion
Much of London sits in the hard to very hard water range — as confirmed by Thames Water.² Limescale accumulation at compression joints and soldered connections creates corrosion stress points that eventually fail under pressure.
In London properties, joint failure at limescale accumulation points is a frequent cause of burst pipe incidents behind tiles, under floors and within original wall chases — locations where the failure runs undetected until surface damage appears.
Frozen pipes in cold snaps
London winters are mild on average but sustained cold snaps — particularly in January and February — cause pipe freezing in poorly insulated properties, loft spaces and external wall cavities.
When water freezes in a pipe it expands, splitting the pipe or blowing joints. The burst typically occurs when the pipe thaws, not when it freezes — which is why burst pipe callouts surge on mild days following a cold snap rather than at the coldest point.
Pipes most at risk in London properties: supply pipes in uninsulated loft spaces, pipes running through unheated external wall cavities in Victorian terraces, and condensate pipes on boilers.
Insurance and escape of water
Escape of water is one of the most common and costly domestic insurance claim categories in the UK.³
Most home insurance policies cover sudden damage from burst pipes — gradual leaks, wear and tear and pre-existing damage are typically excluded. Notify your insurer at the same time as calling a plumber — do not wait until after repair. Take photographs before any work starts.
Your insurer may have a preferred contractor, but you are not obliged to use them. See our New Homeowner Plumbing Guide for what a newly purchased London property’s pipework typically needs checking.
What burst pipe repair costs in London
London burst pipe repair rates sit above national averages due to operating costs specific to the capital — including parking restrictions, congestion-related delays and insurance requirements.
These are the realities of a compliant, insured London plumber — not excessive margins.
Typical current ranges for London burst pipe repair work are outlined below. Actual costs vary by pipe location, access, repair method and reinstatement required. Always confirm the call-out rate before the plumber attends.
See our London Plumbing Costs Guide for the full breakdown.
| Service | Typical London range |
|---|---|
| Emergency call-out (burst pipe, out of hours) | £120–£180 |
| Burst pipe repair — accessible pipe | £200–£350 |
| Burst pipe repair — under floor or behind wall | £400–£900 |
| Lead pipe replacement (section) | £300–£600 |
| Full supply pipe replacement (pavement to property) | £800–£2,000 |
| Leak trace prior to repair | £200–£400 |
| Reinstatement — floor or wall (materials and labour) | £300–£900 |
Always confirm the call-out fee, hourly rate, whether parts are included, and whether reinstatement is quoted separately before the plumber attends.
A burst pipe repair that requires opening up floors or walls will always cost more than the pipe repair itself — confirm the full scope before agreeing to proceed.

Frequently Asked Questions
Turn off the water at the mains stopcock immediately — clockwise until it stops. If you cannot locate or operate the internal stopcock, use the external stopcock in the pavement outside the property.
If water is near electrics, isolate at the consumer unit. Take photographs before calling a plumber and before any drying or reinstatement work starts — your insurer will need them. Then find your borough in the grid above and contact 2–3 verified plumbers to compare availability and confirm arrival time.
Most home insurance policies cover sudden and unforeseen damage from a burst pipe — including water damage to floors, walls, ceilings and contents. Gradual leaks, wear and tear and pre-existing damage are typically excluded.
Notify your insurer at the same time as calling a plumber — not after the repair is complete. Take photographs before any work starts. Your insurer may suggest a preferred contractor but you are not obliged to use them.
In most London properties the internal stopcock is under the kitchen sink. In Victorian terraces it may be under the stairs, in a built-in cupboard near the front door, or in a boxed void near the party wall. In flats it is often inside a shared riser cupboard on your floor.
If you cannot locate or operate the internal stopcock, the external stopcock is in the pavement outside the property under a small metal cover marked "water." Find it before an emergency — not during one.
A burst pipe involves a sudden failure of the pipe wall or a joint — typically producing immediate, uncontrolled water flow. A leak is a slower loss of water, often at a joint or pinhole, that may run for weeks or months before becoming visible.
Both require repair but have different urgency levels. A burst pipe is an emergency requiring immediate water isolation and same-day repair. A confirmed slow leak that has been isolated at a stopcock can wait for a next-day appointment.
A burst lead pipe should be replaced, not patched. Lead pipe is brittle and old — a patch repair on a section that has failed once is a temporary measure on a system that will fail again.
If your property was built before 1970 and has not had its supply pipework replaced, a full supply pipe survey is worth commissioning alongside the burst pipe repair. See our Victorian Terrace Plumbing Guide for what older London properties typically contain.
