Boiler repairs in City of London
Common Boiler Repairs We Carry Out
No heating or hot water
The most common boiler repair call in London. Usually a diverter valve fault on combi boilers (heating works, hot water doesn't) or a pump failure (neither works). Both are same-day repairs in most cases — we carry parts for all major brands.
Boiler losing pressure
Low pressure on the gauge (below 1 bar) means either a system leak or a failed expansion vessel. We identify which with a pressure test. An expansion vessel replacement typically takes 1-2 hours and resolves pressure loss permanently.
Boiler making noise
Kettling (banging, rumbling) is caused by limescale in the heat exchanger — extremely common in London due to hard water. A descale or power flush resolves this. Circulating pump noise (whirring, grinding) means the pump bearings are failing — replacement recommended.
First-time fix rate: our engineers carry the most common spare parts for Vaillant, Worcester Bosch, Baxi, Ideal, Glow-Worm and Potterton boilers. Most London boiler repairs are completed in a single visit — we aim for a first-time fix on every call-out.
