Oil boiler servicing in Belfast

Belfast is mostly gas, which is exactly why oil boiler owners in the city can struggle to find an engineer who does both. Blueprint does. An oil boiler service is a fixed £89, including VAT, and you can book it online.

You will find oil boilers in homes on the edges of the city, on roads the gas main does not reach, and in larger older houses that kept their working systems. Bungalows and detached homes around Castlereagh, Carryduff and Dundonald are common examples. Many are kitchen or utility room boilers; some are external units on a back wall.

What the oil service includes

Oil boilers need more hands-on work each year than gas. Our oil service follows the manufacturer’s checklist and typically includes:

  • replacing the burner nozzle where the maker specifies, and checking or replacing the oil filter
  • cleaning the combustion chamber, baffles and flue ways
  • checking the electrodes, photocell and burner settings
  • checking the oil supply line and fire valve back towards the tank
  • combustion readings with a calibrated analyser, adjusting the burner to the maker’s figures
  • an OFTEC CD/11 service record

A well set-up burner burns cleaner, which matters when oil prices are high. More detail on our oil boiler service page.

Check there is oil in the tank and that the engineer can get to both the boiler and the tank. If the boiler has been locking out, tell us when you book. If the tank is old, we will tell you what we see, though tank replacement is a separate job.

If the gas main reaches your road, converting may be worth looking at. Our guide to oil to gas conversion in NI sets out the steps. Until then, keep the oil boiler serviced.

£89 including VAT, fixed. That covers the full service and the OFTEC CD/11 record. If a part beyond the usual nozzle and filter is needed, we tell you the price first.
Plenty of Belfast homes never converted, either because the gas main does not reach their road or because the oil system was working well. We service oil boilers across the city.
The common makes in Northern Ireland, including Grant, Firebird, Warmflow and Worcester Bosch oil models, plus most others. Tell us the make when you book if you know it.
No. Turn it off and book a repair visit. Smoke or a strong oil smell usually means the burner is out of adjustment and needs looking at soon.
