About this service
Boiler Flue & Condensate Work in South West London, done properly the first time
Two of the most common wintertime call-outs in Kingston upon Thames are a frozen condensate pipe locking out an otherwise healthy boiler, and a flue that fails inspection because a neighbouring extension changed the clearances.
We re-route condensate internally wherever possible, upgrade external runs to a larger insulated pipe and fit soakaway or internal termination correctly so it does not recur next cold snap.
On flues we handle extensions, terminal relocations, flue guards, and the inspection hatches required where a flue runs through a ceiling void.

Frequently asked
Your questions, answered
My boiler locks out every cold morning — why?
Almost always a frozen condensate pipe. Thawing it restores operation, but the permanent fix is re-routing or upsizing and insulating the run.
Do I need flue inspection hatches?
If your flue runs through a ceiling void or boxing where it cannot be visually inspected, yes — engineers cannot legally sign off a service without access.
Are your boiler flue & condensate work engineers Gas Safe registered?
Yes — every engineer working on boiler flue & condensate work in South West London is Gas Safe registered, manufacturer-trained and fully insured to £5m public liability. We'll show our ID on arrival.
