Boiler service in Derry / Londonderry from £79

Derry / Londonderry is on the firmus energy Ten Towns network, which brought natural gas to the north west from the mid-2000s. That is much later than Belfast, and it shows. Many households converted, but a lot of homes kept their oil boilers, either because they were happy with them or because the cost of switching did not add up at the time.

So in Derry you are as likely to need an oil service as a gas one. We are Gas Safe and OFTEC registered, and we service both at fixed prices. If you are weighing up a switch, our guide to oil to gas conversion in NI sets out what is involved.

Cityside. Older terraces around the Bogside, Rosemount and the streets inside and near the walls often have boilers fitted in tight kitchens with short flues. Newer estates further out, towards Shantallow and Culmore, tend to have combi boilers.

Waterside. A mix of older housing near the river, larger semis and detached homes up the hill, and newer developments towards Drumahoe. Gas and oil both turn up here.

The villages. Eglinton, Newbuildings, Strathfoyle and the rural roads towards Claudy have more oil tanks, more external boilers and longer drives between jobs. Same price, same checklist.

An oil service is more hands-on than a gas one. We replace the nozzle where the maker specifies, check and change filters, clean the combustion chamber and baffles, set the burner and take flue gas readings with a calibrated analyser. You get an OFTEC CD/11 record, which is the standard document for an oil appliance service.

Homes near the Foyle and across the open ground towards Lough Foyle can be exposed to wind and weather. External oil boilers and tanks in those spots are worth a careful look each year: we check the casing, seals, flue and the oil supply line as part of the service.

Gas boilers get the same treatment as anywhere else: the manufacturer’s checklist, gas pressure and flue checks, safety device tests and combustion readings recorded. See gas boiler service for the full list.

Derry / Londonderry has a lot of rented housing, including student lets near the university. Gas appliances in rented homes need a gas safety check every 12 months; we do it with the service for £119. See the landlord page.
