About this service
Boiler Installation in South West London, done properly the first time
A new A-rated boiler typically cuts gas use by a quarter or more compared to an older model — and the right size matters more than the brand. An oversized boiler short-cycles, wears out faster and costs more to run than one properly sized to your home's actual heat loss, which is why we survey before we quote rather than pricing over the phone.
A like-for-like swap is usually a one-day job. Moving the boiler, converting from a conventional system to a combi, or fitting a new cylinder typically takes two to three days — we tell you which applies and give you a fixed price in writing before anyone starts.
