About the area

Georgian market town on Firmus, surrounding Lagan Valley farmland on oil. Market Square conservation + listed overlay meets rural tank-replacement rhythm.

Dromore is on the Firmus Energy network for most of the town. Surrounding agricultural properties remain oil-heated. Our Dromore workload splits roughly 55% gas, 45% oil.

Dromore's Georgian market town character runs down the hillside to the Lagan river, with the cathedral (St Colman's) marking the old centre. Residential expansion has happened in private estates off the Banbridge Road, Hillsborough Road and Ballynahinch Road, mostly 1980s onwards. Firmus Energy reached Dromore in the 2000s and covers most of the built-up town, though period centre homes (Georgian and Victorian) often retain oil due to flue routing complexity on listed or conservation-area buildings. Rural agricultural properties in the surrounding countryside are entirely oil-dominant: big tanks, big boilers, often running multiple heating zones for farmhouses and outbuildings. Dromore's commuter demographic (Belfast via A1, Craigavon and Lisburn all reachable) drives a steady flow of modern installs alongside the heritage and rural work.

How we work here

What Dromore homes need.

Every area has its own housing stock and heating mix. Here's how that shapes the work we do in Dromore.

Housing stock

Georgian Market Square and Cathedral Hill properties. Victorian and Edwardian streets near the town centre. 1980s to 2020s private estates off the Banbridge, Hillsborough and Ballynahinch Roads. Larger rural bungalows and farmhouses in surrounding countryside.

Heating pattern

Firmus Energy in the modern town core. Oil dominant in the rural hinterland. Period centre properties often retain oil. Combi boilers on newer estates, oil on farms and older rural homes.

Common jobs in Dromore

  • Oil boiler servicing on rural agricultural properties.
  • Oil-to-gas conversions where Firmus has recently reached properties.
  • Gas boiler installations on 1990s to 2020s private estate properties.
  • Annual gas servicing across the town core.
  • Agricultural-property multi-boiler work on working farms.
  • Heritage-sensitive installs on Georgian Market Square properties.
  • Power flushing on longer-neglected 80s and 90s systems.

Local considerations

Things to know in Dromore.

Rural Dromore properties often have oil tanks that are 20-plus years old. OFTEC compliance on condition is worth checking during any oil service.

The Lagan Valley's river flood risk affects some lower-lying properties around Dromore. Boiler siting above potential flood levels is important on at-risk properties.

Georgian Market Square buildings are listed. Any external boiler work requires listed-building consent. We handle the paperwork.

Housing stock in depth

Property types and what they need.

Dromore is not one kind of house. Each era has a different pipework shape, different failure modes, and a different correct answer on replacement. Here's how that plays out on the ground.

01 · c. 1780-1840

Market Square / Cathedral Hill Georgian stock

BT25

Georgian townhouses, terraces and listed properties around Market Square, Cathedral Hill and the streets down to the Lagan. Stone or 9-inch brick construction, slate roofs, many listed.

Typical setup

Combi or system boiler in rear kitchen or basement utility. Pipework mixed across heritage retrofits. Condensate and flue routing constrained by conservation and listed-building rules.

Common issues

  • Listed Building Consent needed for most external changes.
  • Flue position limited to rear or side elevations.
  • Lagan Valley flood risk on some lower-lying properties.
  • Tundish discharge constrained by heritage fabric.

Best practice on replacement

Conservation-officer consultation at survey. Rear-elevation flue. Listed Building Consent process adds 6-12 weeks to timeline. Heritage-safe flushing on retained rads.

02 · c. 1985-present

1980s-2020s estate (Banbridge / Hillsborough Road)

BT25

Private estate stock off the Banbridge, Hillsborough and Ballynahinch Roads. Three- and four-bed detached and semi-detached, 100-150 sqm.

Typical setup

Firmus gas combi or system from build or early retrofit. Pipework to modern standards. Consistent builder layouts per estate phase.

Common issues

  • Original boiler 15-30 years old on earlier estate phases.
  • Magnetic filter absent on pre-2012 installs.
  • Unvented cylinder expansion vessel pre-charge loss.
  • Filling loop flexi-hose permanent.

Best practice on replacement

Like-for-like swap with magnetic filter. Expansion vessel replace. Fixed filling loop. Smart thermostat retrofit.

03 · c. 1945-2005

Rural Lagan Valley oil-heated farmhouse

BT25

Farmhouses and rural bungalows through the surrounding Lagan Valley countryside, off the Firmus network. External oil tank, internal or external boiler, often multi-boiler for working farms.

Typical setup

Grant Vortex, Warmflow Professional, Firebird Envirogreen oil boilers. Larger 1,800-2,500L tanks on farms. Some multi-zone layouts for house + outbuildings.

Common issues

  • Pre-2003 single-skin tanks approaching end-of-life.
  • Lagan Valley flood risk on low-lying properties affecting boiler and tank siting.
  • Burner nozzle drift.
  • Multi-boiler interconnects without zoning.

Best practice on replacement

Bunded tank to current OFS T100 spec, sited above local flood risk where possible. Match burner nozzle. Proper zone controls on multi-boiler farms. Annual OFTEC service baseline.

Technical constraints

Pressure, flues and planning.

The bits of a boiler install that determine whether your quote is realistic or optimistic. Most of these are checked at survey, not after.

Mains pressure and flue routing

NI Water mains pressure in Dromore sits around 2.8-3.3 bar. Rural properties on well water or spur supply show more variance. Flue routing on Market Square heritage stock is conservation-constrained; suburban estates are standard Approved Document J / Gas Safe MI. Lagan Valley flood-plain affects some lower-lying properties; boiler siting above flood level is important on at-risk properties.

Planning constraints

Dromore Market Square, Cathedral Hill and the historic core are a conservation area. A significant cluster of listed Georgian buildings around Market Square and Cathedral Hill need Listed Building Consent for any external heating work. Banbridge and Limavady Borough Council's conservation officer is the contact. Estate stock off the Banbridge, Hillsborough and Ballynahinch Roads is standard permitted-development territory.

Common questions

Dromore FAQ.

My oil tank is 25 years old. Should I replace?

OFTEC spec T100 covers condition-based replacement. Rust, seam weeping, or base settlement are warning signs. A new 1,350L bunded tank costs £800 to £1,100 installed; a 1,800L farm tank £1,400-plus. Worth doing proactively before failure.

Firmus has reached our estate. Conversion options?

Oil-to-gas conversion in Dromore typically runs £3,500 to £4,500 including boiler, Firmus connection liaison, oil tank removal, and commissioning. Running-cost saving is usually £300 to £500 a year, and payback is 7 to 10 years.

Our farmhouse has two boilers: one for house, one for outbuildings. Can you service both?

Yes, standard workload for us around Dromore. We service both during a single visit, coordinate spares if any parts are needed, and issue separate certificates for each appliance.
