Belfast is on the Phoenix Energy gas network, the largest gas network in Northern Ireland. Gas mains run under most streets in the city, from the terraces off the Shankill and the Falls to the semis of the outer suburbs. That is why far more people in Belfast search for a gas boiler service than an oil one.

That does not mean every Belfast home is on gas. You will still find oil boilers in:

  • houses on the edges of the city, where the gas main may not reach every road
  • larger older homes in south and east Belfast that kept a working oil system rather than convert
  • some bungalows and detached homes around Dundonald, Carryduff and Dunmurry

We service both, so you do not need to know which engineer to call. If you are not sure what fuel your boiler uses, look for a gas meter outside the house or an oil tank in the garden. Our gas boiler service in Belfast and oil boiler service in Belfast pages go into each in more detail.

Belfast housing is a mix, and each type brings its own servicing points.

Victorian and Edwardian terraces. Common across north, south and east Belfast. Many have a combi boiler fitted in a kitchen or a converted cupboard, sometimes with a flue running through a tight rear return. We check the flue route and terminal clearance as part of every service, because a flue that met the rules when it was fitted can end up too close to a newer extension or a neighbour’s window.

Post-war and 1960s to 1980s semis. Often converted from oil or solid fuel to gas over the past twenty years, so the boiler may be newer than the pipework and radiators. Sludge in old radiators is a common reason a newer boiler struggles.

Apartments and new builds. City centre, the Titanic Quarter and newer developments around the edges of the city tend to have compact combi boilers with long horizontal or vertical flues. Access to the flue matters, so tell us if yours exits high up or into a shared space.

Rented homes. Belfast has a large private rented sector. Landlords must have a gas safety check every 12 months, and we can do the service and the CP12 in one visit. See our landlord page for the details.

What a Blueprint service includes

Every service follows the boiler manufacturer’s checklist, not a generic one. On a gas boiler that means checking and cleaning the burner and heat exchanger where the maker says to, testing safety devices, checking gas pressure and the flue, and recording combustion readings with a calibrated analyser. On an oil boiler it means a new nozzle and filter where needed, cleaning the combustion chamber, setting the burner and recording the readings on a CD/11.

You get a digital service record with the readings, so you have proof for your warranty and a baseline for next year. The full list is on our boiler service page.

We cover every Belfast postcode from BT1 to BT17, including:

  • North Belfast: Antrim Road, Cavehill, Oldpark, Ardoyne, Ligoniel (BT14, BT15)
  • South Belfast: Malone, Stranmillis, the Lisburn Road, Ormeau, Rosetta, Newtownbreda (BT7, BT8, BT9, BT10)
  • East Belfast: Ballyhackamore, Belmont, Sydenham, Knock, Gilnahirk, Cregagh (BT4, BT5, BT6, BT16)
  • West Belfast: Falls, Andersonstown, Shankill, Glencairn, Poleglass (BT11, BT12, BT13, BT17)
  • City centre: BT1, BT2, BT3

Just outside the city we also cover Dundonald, Castlereagh, Carryduff, Dunmurry, Holywood and Newtownabbey. If you are further out, try the Lisburn or Newtownabbey pages.

If your boiler has stopped working rather than just being due a service, book a repair visit instead. The first hour is £85, and we quote before doing any further work. More on our boiler repair in Belfast page.

The Blueprint Service Plan includes your annual service, booked for you: gas £72 or oil £82 a year paid up front, compared with £79 gas or £89 oil one-off. Members get 15% off repair labour and 10% off parts. Repairs are always charged, and first pick of repair slots is on best endeavours. See boiler care plans.

Demand for boiler servicing in Belfast climbs sharply from September, as the heating goes on, and stays high until January. That is when diaries fill and breakdowns peak. If you can, book your service in late summer or early autumn, before the rush. If your boiler was last serviced in winter, booking the same month each year keeps your warranty record tidy.

If you are already in the busy season, the booking page shows the real next free slot rather than a promise we cannot keep.
