What Happens During a Boiler Service?

A boiler service is a comprehensive check carried out by a Gas Safe registered engineer to ensure the system is working safely and efficiently.

Here’s a step-by-step breakdown of what happens during a boiler service:

The engineer starts by visually inspecting the boiler and its components. They check for:

  • How it ignites
  • Flame consistency and colour (blue flame indicates proper combustion)
  • Pressure levels
  • Any unusual noises indicating wear or damage

3. Internal Components Inspection

The casing of the boiler is carefully removed to inspect key internal components. The engineer examines:

  • Heat exchanger: Checked for blockages, cracks, or limescale buildup.
  • Burner: Ensured it is operating correctly without excessive soot.
  • Fan and seals: Verified for functionality and security.
  • Condensate trap: Cleaned and cleared of blockages.

4. Flue Gas Analysis
