About this service
Back Boiler Removal & Replacement in South West London, done properly the first time
Back boilers sit behind a gas fire in the chimney breast and are still surprisingly common in Kingston upon Thames's post-war housing. They are inefficient by modern standards and increasingly hard to get parts for.
Removal involves isolating and stripping the unit, dealing with the fire front and chimney, capping the flue correctly and relocating the new boiler to a kitchen, utility or airing cupboard with a proper flue route.
It is a bigger job than a swap and needs planning, but the efficiency gain is the largest of any boiler replacement we carry out.
