What's included in a full boiler service
A proper service is a checklist, not a glance. We work through the manufacturer's servicing schedule for your specific boiler model — no two brands are identical.
- Flue routing, termination and ventilation checked.
- Combustion chamber and burner inspection and clean.
- Flue gas analysis — CO/CO₂ ratio, combustion efficiency.
- Gas rate calculation and adjustment if required.
- Expansion vessel charge and pressure relief test.
- Sealed-system integrity, sludge check, magnetic filter service.
- Controls, thermostat and zone valve function check.
- Benchmark logbook stamped and service report emailed.
