Annual Boiler Service
Annual Boiler Service
Annual boiler service in Kingston upon Thames and across South West London by Gas Safe registered engineers — a full strip-down check, combustion test and written report, not a five-minute look.
About this service
Annual Boiler Service in South West London, done properly the first time
An annual boiler service is what keeps a boiler safe, efficient and inside its manufacturer warranty. Nearly every warranty in the UK requires a documented service every twelve months, and most claims that get refused are refused because that record is missing.
Our service on Kingston upon Thames, KT1, KT2 and TW9 properties covers the burner and heat exchanger, the flue and its seals, gas pressure and flow rate, combustion analysis with a calibrated analyser, the condensate trap, the expansion vessel charge, all safety devices and system pressure. You get a written report of the readings, not just a verbal 'all fine'.
If we find something starting to go, you hear about it while it is still a small planned job. Most of the December no-heat call-outs we attend were visible months earlier on a service sheet.

Frequently asked
Your questions, answered
How often should a boiler be serviced?
Once every twelve months. It is a condition of virtually every manufacturer warranty, and it is a legal requirement for landlords alongside the gas safety check.
How long does an annual service take?
Typically 45 minutes to an hour for a domestic boiler in good condition. Longer if the casing has not been off for years or we find something that needs investigating.
What does a boiler service cost?
It depends on the boiler type, its condition and access. We give you the price before we book — but we do not publish a figure here because parts and older appliances change the picture.
Will you service a boiler you did not install?
Yes. We service all major UK brands regardless of who fitted it, and we can register the service against your manufacturer warranty.
