Annual Boiler Service in London

Annual boiler service in London: what the price includes

• 01
  Full combustion analysis

  Flue gas readings printed and kept, the objective health check, not a visual once-over.

• 02
  Warranty protection

  Manufacturer warranties require annual servicing; miss a year and a £2,000 claim can be refused.

• 03
  The small parts checked

  Condensate trap cleaned, magnetic filter emptied, pressure and expansion vessel checked and corrected.

• 04
  Reminders handled

  We track the anniversary and remind you, most lapsed warranties die of forgetfulness, not choice.

• 05
  A service is not the same as a safety check

  A CP12 confirms an appliance is safe today. A service cleans the burner and heat exchanger, checks the seals and combustion figures, and is what actually extends the life of the boiler and keeps the manufacturer warranty valid. Plenty of people pay for one believing they bought the other.

Local conditions we work around

Hard water is the defining fact for London heating. At 280 to 320 ppm, scale builds on the hottest surface in the system, which is the boiler heat exchanger, and every millimetre of it costs efficiency and shortens the life of the unit. It is why we flush before commissioning a new boiler, why we fit a scale reducer on the mains where the system warrants it, and why an unvented cylinder in London needs its annual service rather more than the manual implies.
