Unlike standard boiler servicing costs, major boiler servicing costs do tend to differ. The price often depends on the boiler age, it’s make and model, and whether any additional parts are found to be warn or defective and need replacing.
If you think your boiler needs a major service, it’s best to call or email me to request a bespoke price. On average most boiler manufacturers recommend a standard service once a year for 3 years, with a major service every 4th year thereafter, where the boiler is fully stripped down and associated gaskets, parts etc., are replaced, if needed.
