How often should an oil boiler be serviced?
An annual service is normally recommended. Regular cleaning and combustion checks help identify wear, soot build-up and oil-supply issues before they cause a breakdown.

Oil boiler breakdown and repair →Frequently asked questions
What does PCR check during an oil boiler service?
The work depends on the appliance, but typically includes the burner, nozzle, ignition, filters, combustion chamber, flue performance and visible oil-supply components, followed by clear findings.
Can PCR help if an oil boiler keeps locking out?
Yes. Repeated lockout needs diagnosis rather than continual resetting. PCR can check the oil supply, burner, ignition, controls, circulation and combustion performance.
