Annual Boiler Servicing
Regular servicing is essential to keep your boiler working safely and efficiently. We recommend servicing your boiler once a year, ideally before the colder months begin. An annual service can:
- Perfect for older boilers that need maintenance and upkeep
- Improve energy efficiency and reduce fuel bills
- Extend the lifespan of your boiler
- Ensure your boiler is operating safely and correctly
- Maintain your manufacturer’s warranty of 10-12 years (if applicable)
During every service, we carry out a full inspection, clean key components, check for signs of wear, and test the system for performance and safety.
