A leaking supply pipe is rarely obvious — the first sign is often a soggy patch of lawn, a hissing stop tap, or a water bill that's jumped. Because the pipe is buried and metered water is money, speed matters.
WaterTrust Approved — every contractor is identity-checked with accreditation and insurance verified before they can quote.
What the work involves
- Leak location (acoustic or tracer-gas where needed)
- Excavation at the leak point and a WRAS-approved repair fitting
- Replacement of a damaged section where a spot repair won't hold
- Pressure test and backfill/reinstatement
When you need it
- A wet patch, lush green stripe or sinking ground along the pipe route
- The water company has confirmed the leak is on your side
- Your meter spins with everything in the house turned off
- A pipe struck during digging or building work
What supply pipe repairs cost in South London
A located, excavated and repaired supply-pipe leak typically runs £300–£900 depending on depth and surface. If the pipe is old and this is not its first leak, put the money toward renewal instead — repeated repairs on a failing run cost more than renewal over time. One more reason not to sit on a known leak: the water company can serve a notice requiring the repair — commonly within about four weeks — after which they may do the work themselves and charge you. A dated completion certificate from your contractor is what closes the notice.
Repair or renew?
A single failure on otherwise sound pipe: repair. Repeated leaks, a shared supply, or old material — lead, galvanised iron, or the black alkathene plastic of the 1960s–70s that turns brittle with age: renewal quotes belong alongside the repair quote so you can compare the honest lifetime cost. Guarantees mirror the method here too: repairs commonly carry a couple of years, full replacements around ten — in writing, as ever.

Water Supply Pipe Repairs in South London — common questions
How do I check if the leak is mine?
Turn everything off, note the meter, wait 30 minutes and read it again. Movement points to a leak on your side — the water company can confirm which side of the stop valve it's on.
How do I know the leak is on my pipe?
The two-minute test: everything off, watch the meter. Movement means a leak on your side of the meter — usually the underground supply pipe.
Will my water be off long?
For the repair itself, typically an hour or two — the pipe is exposed first, so the interruption is planned, not open-ended.
Will Thames Water / SES Water repair it for me?
Some companies repair or subsidise a first external supply-pipe leak, and metered customers can usually claim a leak allowance once fixed — ask when you report it before paying anyone.
