Pre-Winter Boiler Check
Pre-Winter Boiler Check
Pre-winter boiler check in Kingston upon Thames and South West London — get your heating serviced and stress-tested before the first cold snap, instead of joining the December queue.
About this service
Pre-Winter Boiler Check in South West London, done properly the first time
A boiler that sat idle all summer is where problems hide: seized pumps, sticking diverter valves, blocked condensate traps, corroded heat exchangers and flat expansion vessels. None of them show themselves until you switch the heating back on.
Our pre-winter check runs the full annual service, then puts the system under load: we bring the heating up to temperature, check every radiator heats evenly, verify the condensate route is protected against freezing, confirm the frost stat and controls behave, and top up and re-balance where needed.
September and October are the right window. From the first genuinely cold week, appointments across KT2, KT1, TW11, SW19 and TW9 book out one to two weeks ahead because emergency call-outs take priority. Booking early gets you a slot at a time that suits you and a planned repair on a mild day rather than an emergency one in the cold.

Frequently asked
Your questions, answered
When should I book my pre-winter boiler check?
Late August through October is ideal. That is before the first cold week, when our diary is still open and any repair can be planned rather than rushed.
Is this different from a normal annual service?
It includes the full annual service, plus a heating run under load, radiator-by-radiator checks, control testing and condensate frost protection — the things that only matter once you actually need heat.
My boiler seems fine — is it worth it?
A boiler that runs is not the same as a boiler that is safe and efficient. Combustion drift, a weak expansion vessel and a partially blocked condensate all run fine in September and fail in January.
What if you find a fault?
We explain it plainly, tell you whether it needs doing now or can wait, and give you a fixed written price before any repair goes ahead.
