More information
What a combi boiler service covers
A service is designed to confirm safe operation, improve reliability and highlight developing issues. Depending on your boiler model and condition, it typically includes:
- Visual inspection of the boiler, flue and ventilation
- Operational checks for heating and hot water
- Safety checks on key gas or oil components (as applicable)
- Internal inspection and cleaning where required
- Combustion analysis and adjustments within manufacturer tolerance
- Checks of seals, condensate pipework and pressure
- Review of controls and system response
- Written summary of findings and any recommendations
When this service is most useful
- You want confidence your boiler is operating safely.
- Your heating is working but you have concerns about noise, pressure drops, or inconsistent hot water.
- You are aiming to reduce the risk of winter breakdowns.
- You need routine maintenance to help protect manufacturer warranty terms (check your handbook).
- You look after a rental property and want planned maintenance (note: this is different from a landlord gas safety certificate).
How the service is delivered
The engineer will carry out a structured set of checks based on the boiler type and manufacturer guidance. Where safe and appropriate, the case is removed for internal inspection, components are checked for wear and the appliance is tested under operating conditions. You will be told what has been checked, what the results mean, and what to do next if anything needs attention.
After the service
If everything is operating correctly, you will have a clear record of the visit and reassurance going into the next season. If issues are found, you will get practical recommendations and options for repair or further investigation, with transparent explanation before any additional work is agreed.
