Expert Boiler Repair Across London
A broken boiler is more than an inconvenience - especially in winter. Our qualified engineers carry a comprehensive stock of common parts and can fix most boiler faults on the first visit. If your radiators are cold at the bottom or the boiler is kettling, a proper clean is often the root cause — our power flush cost guide for London explains when a flush is worth it and when it is not.
We service and repair all major boiler brands, offering transparent fixed-price quotes before any work begins. No surprises, no upselling - just honest, professional repairs. Landlords in particular should know that a combined boiler service and landlord gas safety certificate (CP12) is usually cheaper than two separate visits — and pairs well with the 5-yearly EICR electrical inspection that private rentals now legally require.
