What's included in an annual boiler service?

An annual boiler service includes a visual inspection, safety checks, flue gas analysis, component cleaning and a Gas Safety Certificate on completion.

What Happens During a Boiler Service

A thorough annual service typically includes:

  • Visual inspection of the boiler casing, seals and pipework
  • Checking the flue for safe operation and correct gas flow
  • Flue gas analysis to check combustion efficiency
  • Checking gas pressure and burner condition
  • Testing safety devices (pressure relief, thermostats)
  • Checking the condensate pipe for blockages
  • Cleaning components as needed
  • Issuing a service report and, for landlords, a Gas Safety Certificate (CP12)

Why It Matters

Annual servicing keeps your manufacturer's warranty valid, reduces the risk of mid-winter breakdowns, and ensures safe operation. Book your annual service with RARE — call 020 7458 4949.
