Keston boiler repair and servicing across London

About Keston

If you live in a London flat, Keston could be the brand that matters most. Its twin-flue design allows very long flue runs. So a boiler can still go in when it can’t sit near an outside wall and a normal flue won’t reach. In high-rise blocks and deep-plan conversions, that can decide whether a boiler can be fitted at all.

Faults we often find on a Keston

• Long flue runs in flats where the boiler is far from an outside wall
• High-rise and deep-plan buildings with limited flue routes
• Condensate pipework over long runs that needs careful planning

This is what tends to crop up, not a verdict on yours. An engineer checks your boiler in person and finds the fault before giving you a price.

Asked about Keston

There’s nowhere in my flat for a normal boiler flue. Can that be solved?

Often it can. This is exactly what twin-flue systems are for. The flue can run much further than on a standard boiler, so the boiler can sit where a normal flue would never reach. It has to be designed properly, not made up on the day. We’ll check the route before recommending it.

Can you fix and service my Keston?

We can. Our gas work is done by Gas Safe registered engineers. By law, that is what any gas boiler needs, whatever the make.
