Questions
Oil boiler servicing FAQ.
How much does an oil boiler service cost?
A standard oil boiler service is £95 including a new nozzle, photocell clean, combustion check and written report. Landlord certificate on top is £20. All-in with a minor repair on the day is from £140.
How often should I service my oil boiler?
Every 12 months. Oil boilers accumulate soot and sludge faster than gas, so skipping a year noticeably hurts efficiency and can fail your manufacturer warranty.
What brands do you service?
Warmflow, Grant, Worcester Heatslave, Firebird, Trianco, Riello burners, Mistral, most domestic oil-fired boilers sold in NI. Message us with the make and model if you're not sure.
Are you OFTEC registered?
Yes, OFTEC registered. OFTEC is to oil what Gas Safe is to gas: the statutory competence register. Installers issue OFTEC-format inspection sheets and our Every installer is Gas Safe registered in their own name if you also have gas appliances.
Will you replace a nozzle on the day?
Yes. A nozzle change is part of the standard service. If the installer finds a failed photocell or leaking flexi, an installer will quote the repair before doing it.
