Lisburn.
Lisburn sits south-west of Belfast and is one of our busiest areas outside the city. From the historic centre out to Knockmore, Hillhall and the BT28 estates, we've fitted boilers across every kind of housing stock.

About the area
Lisburn's on Firmus Energy. We liaise with them directly on every install.
Lisburn is served by Firmus Energy rather than Phoenix, which changes how we approach gas installs and oil-to-gas conversions. Plenty of Lisburn properties still run on oil, which is why oil-to-gas conversions are one of our most common calls here.
Lisburn became a city in 2002 but its housing stock reflects every phase of post-war expansion. The older centre around Market Square and Bow Street has Victorian terraces and converted warehousing. Hillhall and Old Warren are dominated by 1970s semis and bungalows. Knockmore and Pond Park are newer-build estates from the 1990s onwards, mostly gas combi setups. Surrounding villages like Drumbo, Moira and Hillsborough feed into our Lisburn workload. The city's mix of older oil-heated properties and newer gas homes means we split almost 60/40 between gas servicing and installs, and oil-to-gas conversion work, on any given month.

How we work here
What Lisburn homes need.
Every area has its own housing stock and heating mix. Here's how that shapes the work we do in Lisburn.
Housing stock
Mix of Victorian centre properties, 1970s Housing Executive stock in Hillhall and Old Warren, 1990s to 2000s private estates in Knockmore and Pond Park, and outlying bungalows in Drumbeg and Dunmurry. More semi-detached than inner Belfast.
Heating pattern
Firmus Energy is the gas provider. Gas coverage is around 70% city-wide but patchy in outlying villages where oil still dominates. Combi boilers on newer estates, oil boilers with cylinders on older rural-edge properties.
Common jobs in Lisburn
- Oil-to-gas conversion in 1970s semis newly connected to Firmus mains.
- Gas boiler replacements in Knockmore and Pond Park new-builds hitting the 10-year mark.
- Oil boiler servicing on Dunmurry and Drumbeg bungalows.
- Unvented cylinder upgrades replacing cold-water loft tanks in period homes.
- Landlord gas safety certificates across the BT27 rental market.
- Bathroom refits in tidy semi-detached properties.
- Power flushing following sludge-heavy 30-year-old radiator systems.
Local considerations
Things to know in Lisburn.
Firmus liaison matters. We handle the gas service connection paperwork directly with Firmus on oil-to-gas conversions, so you don't have to coordinate between two contractors. Firmus sometimes runs seasonal connection subsidy schemes worth asking about.
Lisburn's older oil tank stock is often approaching end of life. When converting to gas, tank removal and correct disposal is part of our standard quote.
Parts of BT28 still rely on gravity-fed hot water from loft tanks. Mains upgrade plus unvented cylinder is a frequent ask.

Common questions
Lisburn FAQ.
My street is on Firmus, not Phoenix. Does that affect your work?
No difference to how we install. Firmus Energy's service connections are standard for us and we handle all liaison directly. Firmus have different tariff structures than Phoenix, so your running-cost comparison will vary.
We're thinking of switching from oil to gas. What's the process in Lisburn?
Three-step: we survey the property, liaise with Firmus on gas connection, then handle the boiler install, old boiler and tank removal, and commissioning. Most Lisburn conversions take 2 to 3 days on site. Whole-project timeline including Firmus connection is 4 to 8 weeks.
How quickly can you get to Knockmore or Hillhall?
Twenty minutes from our base in Belfast. Same-week for standard work, same day for emergencies.
We're outside the Firmus gas network in rural Lisburn. Can you still help?
Yes. We service oil boilers across Lisburn and the outlying villages. We're OFTEC registered and fit Grant, Warmflow, Firebird and Worcester Heatslave regularly around BT27 and BT28.
