As Gas Safe registered engineers we install, repair and service boilers throughout Gravesend, Kent and London. We size the boiler to the property — combi, system or heat-only — fit it cleanly to current standards, and register the manufacturer warranty on your behalf.
For repairs we diagnose the fault properly — ignition, diverter valve, pump, heat exchanger or PCB — and quote before replacing parts, so you're never paying for a component you didn't need. Our annual servicing keeps warranties valid, maintains efficiency, and catches small faults before they become winter breakdowns.
What's included
- Combi, system and regular boiler installation
- Like-for-like and system upgrades & conversions

Boiler Installation, Repairs & Servicing FAQs
Which boiler brands do you install?
We're accredited installers for leading brands including Worcester Bosch, Vaillant and Ideal, which means we can offer extended manufacturer warranties. We'll recommend the right boiler for your home's size, water pressure and hot-water demand rather than pushing a single make.
How often should my boiler be serviced?
Once a year. Annual servicing keeps your manufacturer warranty valid, maintains energy efficiency, and catches issues like a failing pump or blocked condensate before they cause a winter breakdown.
My boiler keeps losing pressure — can you fix it?
Yes. Pressure loss is usually a leak on the heating side, a faulty pressure-relief valve, or the expansion vessel needing a recharge. We find the root cause and fix it, rather than just topping up the pressure each week.
Do you power flush before fitting a new boiler?
Where the existing system has sludge or debris, yes — power flushing before commissioning a new boiler protects the heat exchanger and is often a condition of the manufacturer warranty.
