About this service
Boiler Leaking Water in South West London, done properly the first time
Water coming from a boiler comes from a handful of places: a failed pump or valve seal, a corroded heat exchanger, a leaking pressure relief valve, perished pipework connections under the unit, or a blocked condensate trap overflowing.
The urgent part is that water and electronics do not mix. A slow leak onto a PCB turns a modest repair into a major one, so it is worth isolating the appliance and getting it looked at promptly.
We identify the source, tell you plainly whether it is a seal-and-part job or a failing heat exchanger, and give you a fixed price with an honest repair-or-replace view on older boilers.

Frequently asked
Your questions, answered
Should I turn the boiler off if it is leaking?
Yes. Switch it off at the fused spur, close the water supply to the boiler if you can reach it, and contain the water until we arrive.
Is a leaking boiler dangerous?
Water on live electronics is a real risk, and a leak from the combustion side can affect safe operation. Treat it as urgent.
Is it worth repairing?
A seal, pump or valve usually is. A corroded heat exchanger on an old appliance often is not — we will show you the comparison rather than push either way.
