  What a gas boiler service includes, step by step

  The engineer starts by asking how the boiler has been behaving. Then they check it is working before touching anything. The case comes off and they look inside for leaks, corrosion and scorch marks. The burner, fan and heat exchanger are checked and cleaned where the maker says so. The condensate trap is emptied, because a blocked one is a common cause of winter lockouts. Seals are inspected. The gas pressure is measured, and a flue gas analyser checks the boiler is burning cleanly and not making carbon monoxide. The flue is checked from end to end. Finally the system pressure is set, the readings are written down, and your service record is filled in. If a part needs replacing, you get a fixed price first.

  Boiler service in London: booked, not chased

  We service gas boilers across London and the towns around it at one fixed price of £89, with no call-out fee and no extra for your postcode. You pick the date. The engineer who comes is Gas Safe registered, employed by us and carries their ID card. Most services take about forty-five minutes. London's hard water is worth mentioning: scale builds up inside boilers here faster than in soft-water areas, so the engineer will tell you if they see signs of it. They will also tell you if everything looks fine, which is the most common result. Either way you get a written record, and we remind you when the next one is due.

  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

A service in a hard-water area is worth more than the certificate. At London hardness, checking the heat exchanger for scale, the condition of the system water and the state of any scale reducer is what actually extends the life of the appliance, and it is the part a cheap service skips. Unvented cylinders in London need their annual attention rather more than the manual implies for the same reason, the coil scales, and performance falls away long before anything fails outright.
