A central heating boiler works hard all year round. Periodic maintenance keeps it safe, efficient and reliable, and is often a condition for your manufacturer's warranty.
- Maintenance keeps your boiler safe (carbon monoxide)
- A clean boiler is more efficient
- Often a condition for your manufacturer's warranty
- Once every 1–2 years is usually sufficient
Why maintenance is important
During maintenance, we check for carbon monoxide and safe combustion, clean the boiler and adjust it for optimal performance. A well-maintained boiler uses less gas and is less likely to break down at the worst possible moment.

How often is it needed?
For most boilers, a maintenance service is sufficient once every one to two years. Manufacturers often set this as a condition for the warranty. With a maintenance contract, we schedule it automatically.
Or take the hybrid step immediately
