Oil boiler service, OFTEC registered, booked online

OFTEC is the registration body for oil heating technicians in the UK and Ireland. Our OFTEC registration number is To confirm: oftec, and you can check it on the OFTEC website before we arrive. OFTEC registration means the technician is trained and assessed to service oil appliances and to complete the CD/11 service record properly.

An oil service is the one time a year someone qualified looks at your whole oil supply, not just the boiler. We visually check the tank for splits, bulging, weeping seams, a sound base and a working gauge, and we check the fire valve, which shuts off the oil if there is a fire at the boiler.

If we see a problem, we tell you what it is and how urgent it is. Tank replacement and supply line work are quoted separately. To confirm: confirm whether tank and supply line work is offered

Northern Ireland’s oil boilers come from a short list of makers, several of them local. We service all of them, including:

• Grant, including the Vortex range
• Firebird
• Warmflow
• Worcester Bosch oil boilers, including the Greenstar Heatslave and Danesmoor ranges
• Boulter and Mistral
• Riello burners, fitted to many boilers of different makes

If your boiler is older or less common, tell us the make and model when you book so we can bring the right nozzle and parts. To confirm: confirm oil makes serviced and nozzle stock

Most oil breakdowns in winter start as something a service would have spotted:

• Lockouts from a worn nozzle, a blocked filter or a dirty photocell
• Smoke or a smell of oil from poor combustion or a weeping seal
• Soot build-up in the heat exchanger, which wastes fuel and can block the flue
• Water or sludge in the tank reaching the filter
• A tired oil pump losing pressure

If your boiler has stopped and the reset light is on, press reset once. If it does not fire, wait a few minutes and try once more. If it still locks out, stop there and call us: repeated resets can flood the combustion chamber. Our boiler repair page explains how a repair visit works.

Add a heating system check to your service for £30. Allow about 20 minutes on top of the service. We check every radiator for cold spots and signs of sludge, test thermostatic and lockshield valves, check and set the system pressure, and review your timer and thermostat settings.

The check does not include repairs or sludge removal. If we find something that needs work, we explain it and quote before doing anything extra. Choose it as an optional add-on when you book.

• Choose oil on the booking form. Oil is fed from a large tank outside, usually green or black plastic or steel. If you have a tank but are not sure whether it holds oil or LPG, choose Not sure.
• See the price and pick a slot. £89, on screen before you give any details.
• Get confirmation by email, with the date, the time window and the price.

On the day, your technician needs clear access to the boiler and the tank. An oil service takes longer than a gas one, typically because of the strip-down and cleaning. Please make sure there is oil in the tank, as we need the boiler running to set it up and take readings.

• Your CD/11 record. Your OFTEC CD/11 record and service record are emailed the same day, with the combustion readings, work and parts listed. Keep it for your warranty and for selling the house.
• If we find a fault. We explain it in plain terms. Any repair is priced before work starts, and nothing is done without your agreement.
• Next year. We remind you before your next service is due.

There is no oil equivalent of the gas safety record in law, but landlords must keep the heating they supply in safe working order. An annual OFTEC service with a CD/11 record is the clearest way to show you have done that. See landlords for how we handle rentals and portfolios.
