The intention behind annual boiler servicing by a Gas Safe registered engineer is to keep your system efficient and safe; you’ll avoid boiler repair issues and limit your boiler’s running costs.

A standard boiler service includes a full safety check, cleaning of key components, and inspection for wear or faults. The Gas Safe registered engineer will:

• Check the flue and ventilation

• Inspect and clean the burner, heat exchange, and seals

• Test gas pressure and flow

• Look for leaks or corrosion

• Verify the boiler is burning fuel safely

If any issues are found, they could recommend a boiler repair on the spot or for you to book a follow-up appointment. These are likely to require additional boiler repair costs.
