Why is regular boiler servicing important?
Regular servicing keeps your boiler running efficiently, reduces the risk of breakdowns, and ensures it operates safely. It also helps maintain your manufacturer warranty.
How often should I have my boiler serviced?
We recommend servicing your boiler every 12 months, in line with most manufacturers’ warranty requirements.
What does a boiler service include?
A visual and mechanical check of the boiler, flue, seals and safety devices, cleaning where necessary, and a full written report – typically taking 30–45 minutes.
How do I know if my boiler needs a repair?
Common signs include unusual noises, no heat or hot water, a dropping pressure gauge, or the boiler locking out. Get in touch and we’ll advise on next steps.
Is it better to repair or replace an older boiler?
For boilers over 10–15 years old, replacement can be more cost-effective if repairs become frequent. We’ll always give you an honest opinion, not just a sales pitch.
