Boiler Installation Mid and East Antrim

Gas Safe and OFTEC Registered Specialists Serving Ballymena, Larne, Carrickfergus, and Surrounding Areas

Your Local Boiler Installer in Mid and East Antrim

JobDoneNI provides professional boiler installation across Mid and East Antrim, covering Ballymena, Larne, Carrickfergus, and the towns and villages in between. Whether you need a gas combi swap in Carrickfergus or an oil boiler replacement in a rural Ballymena property, every job is carried out by our own Gas Safe and OFTEC registered engineers with no sub-contractors involved.

Mid and East Antrim has one of the most varied heating profiles in Northern Ireland. Carrickfergus and the coastal towns along the east Antrim coast are well served by the firmus energy natural gas network, while Ballymena and much of the inland and rural Mid Antrim area remains predominantly on oil. We are fully accredited for both, which means one company handles your installation from survey to certification regardless of your fuel type.

We will walk you through the building control notification process on completion and make sure you have all the documentation you need before we leave.

Oil Boilers Across Rural Mid Antrim

Oil remains the dominant heating fuel across much of rural Mid Antrim. Properties in and around Ballymena, Broughshane, Ahoghill, and the Glens of Antrim are largely off the mains gas grid, and an oil boiler replacement is often the most practical and cost effective option.

Our OFTEC registered engineers carry out oil boiler replacements across the full Mid Antrim area, including condensing boiler upgrades which deliver significantly better efficiency than older non-condensing units. If the firmus energy network has expanded to reach your street and you are considering a switch to gas, we can check eligibility and give you an honest assessment of whether a conversion makes sense for your property.

“Mid and East Antrim is an area where you cannot assume anything about a property’s fuel type before you visit. The gas coverage along the coast is good, but head inland and oil is still very much the norm. Knowing both means we can give every customer a straight answer.”
