Boiler Servicing – FAQ
How often should I service my boiler?
Annually. Most boiler manufacturers require a yearly service to keep the warranty valid, and annual servicing is the most effective way to catch developing faults before they cause a breakdown.
How much does a boiler service cost?
Our boiler service prices are competitive and confirmed upfront. Call us on 01293 000 000 for current pricing in your area.
How long does a boiler service take?
Most boiler services take 60–90 minutes. We'll give you an accurate time estimate when you book.
Do I need a service if my boiler seems fine?
Yes. Many developing faults produce no obvious symptoms until they cause a complete failure. An annual service catches these early. It's also likely required to keep your manufacturer warranty valid.
Can you service my boiler and issue a Gas Safety certificate on the same visit?
Yes. We can combine a boiler service with a Gas Safety inspection (CP12 certificate) in a single visit – popular with landlords who want to handle both requirements efficiently.
