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)
