Keston boiler repair and servicing in London

Keston boilers

Keston is the brand that matters most for a specifically London problem. Its twin-flue design allows very long flue runs, which makes installation possible in flats and buildings where the boiler cannot go near an external wall and a conventional flue simply will not reach. In high-rise and deep-plan conversions that is sometimes the difference between a workable installation and none.

What we see on Keston boilers

• Long flue runs in flats where the boiler sits far from any external wall
• High-rise and deep-plan properties with constrained flue routing
• Condensate arrangements over long runs needing careful design

These are the patterns we see across the installed base, not a diagnosis of your boiler. Faults are identified on site before anything is quoted.

Keston questions

My flat has nowhere to put a normal boiler flue. Is that solvable?

Often yes, and this is exactly the case twin-flue systems exist for. They allow far longer flue runs than a standard boiler, so a unit can go somewhere a conventional flue could never reach. It needs designing properly rather than improvising, and we would look at the route before recommending it.

Do you repair and service Keston boilers?

Yes. Gas work is carried out by Gas Safe registered engineers, which is the legal requirement for working on any gas boiler regardless of make.
