About the area

Linen-town heritage core, Firmus suburban spine, Lough Neagh-side oil farms. Three contexts in one BT62/63 patch.

Portadown is on the Firmus Energy network for most of the urban core. Surrounding rural and farm properties in Tartaraghan, Loughgall and the wider BT62 / BT63 fringe stay oil-heated. The mix is similar to Lisburn: gas in the town, oil in the country, conversion in between as Firmus extends mains.

Portadown sits on the River Bann and grew as a linen-industry town in the 19th century, with a Georgian and Victorian core around Bridge Street, High Street and Market Street. Post-war expansion filled estates west of the river and along the Mahon Road, plus 1990s-onwards private developments toward Brownstown and Killicomaine. Firmus Energy connected Portadown in the 2000s and the network continues to extend gradually. Larger agricultural properties on the Lough Neagh side run multi-boiler oil setups.

How we work here

What Portadown homes need.

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

Housing stock

Georgian and Victorian centre stock around Bridge Street and High Street; 1960s-70s Housing Executive estates west of the river (Edenderry, Edgarstown, Killicomaine); 1980s-2000s private estates around Brownstown, Mahon Road and Killicomaine West; rural bungalows and farmhouses across Tartaraghan, Loughgall and the BT62 fringe.

Heating pattern

Firmus Energy gas in the urban core (roughly 70% of properties). Oil-dominant on the rural fringe and in outlying villages. Combi boilers on newer estates, system + cylinder in larger homes, Grant / Warmflow / Firebird oil on rural stock.

Common jobs in Portadown

  • Gas combi replacements across 1990s-2000s Brownstown and Killicomaine estate stock.
  • Oil-to-gas conversions where Firmus has recently extended mains in the BT62 spine.
  • OFTEC oil servicing on rural Tartaraghan and Loughgall properties.
  • Annual servicing across the urban core.
  • Power flushing on 1970s Housing Executive systems west of the river.
  • Landlord CP12s across the BT63 town-centre rental stock.
  • Agricultural multi-boiler servicing on Lough Neagh side farms.

Local considerations

Things to know in Portadown.

Portadown's Firmus network has been extending steadily through the 2010s and 2020s; before committing to a new oil boiler in BT62, check current coverage at the boundary.

Bridge Street and parts of the historic Market Street area are within a conservation overlay; external flue routing on front elevations may need consent.

Rural oil tanks across the Loughgall / Tartaraghan farmland are commonly 25+ years old. OFTEC OFS T100 condition inspection during service is the right baseline.

Housing stock in depth

Property types and what they need.

Portadown 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. 1850-1910

Bridge Street / High Street Victorian centre

BT62BT63

Period terraces and townhouses around Bridge Street, High Street and Market Street. Brick or render, slate roofs, original sash windows on retained examples. Conservation-area overlap on parts of the centre.

Typical setup

Combi or system boiler in rear kitchen or basement utility where modernised. Pipework mixed across heritage retrofits. Flue routing constrained on front-facing elevations in conservation streets.

Common issues

  • Conservation-area consent for front-elevation external work.
  • Lead supply pipe still present in some properties.
  • Narrow rear yards limiting flue termination options.
  • Original cast-iron soil stacks where condensate has to integrate.

Best practice on replacement

Rear-elevation flue routing. Replace internal stopcock. Heritage-safe flush on retained period rads. Listed Building Consent check for any individually-listed properties.

02 · c. 1962-1978

1960s-70s Housing Executive stock

BT62BT63

Standardised three-bed semis and terraces across Edenderry, Edgarstown and Killicomaine. Cavity-wall brick, pitched roof, 75-90 sqm.

Typical setup

Original back boiler converted to combi during 1990s-2010s upgrade waves. 15mm / 22mm copper pipework. Single-panel rads.

Common issues

  • Upgrade combi 10-20 years old now.
  • Magnetic filter absent on older installs.
  • Compact kitchen limiting boiler position.
  • External condensate freeze-risk in cold snaps.

Best practice on replacement

Like-for-like swap with magnetic filter. Smart thermostat upgrade. Internal condensate routing or thorough insulation.

03 · c. 1950-2005

Rural oil-heated bungalow or farmhouse

BT62

Detached rural bungalows and farmhouses across Tartaraghan, Loughgall and the wider Lough Neagh side. External oil tank, often multi-boiler farm setups.

Typical setup

Grant Vortex, Warmflow Professional or Firebird Envirogreen oil boilers. Bunded or single-skin oil tank 1,000-2,500L. Multi-zone or multi-boiler on larger farms.

Common issues

  • Single-skin tanks pre-2003 bunding regs.
  • Burner nozzle drift over years of deferred servicing.
  • Long external feed lines freezing in cold snaps.
  • Multi-boiler interconnects without proper zoning.

Best practice on replacement

Bunded tank to current OFS T100 spec. Match burner nozzle to current heat exchanger. Insulate feed lines. Zone controls on multi-boiler farms.

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 Portadown sits around 2.8-3.3 bar at the boundary, consistent across the BT62/63 footprint. Flow-rate testing standard at survey. Flue routing follows Approved Document J / Gas Safe MI distances; conservation streets need rear-elevation positions. Oil flue and tank positioning follow OFTEC Technical Book 3 with required clearances and prevailing-wind considerations.

Planning constraints

Bridge Street, parts of High Street and the historic core are within a conservation area. A handful of listed buildings around Market Street need Listed Building Consent for any external work. Suburban estates west of the river and the Brownstown / Killicomaine developments are standard permitted-development territory. Armagh, Banbridge and Craigavon Borough Council's conservation officer is the contact for consent matters.

Most of the Portadown urban core is. Beyond the centre into the rural fringe, oil is still common. Send us the full postcode and we'll confirm current Firmus coverage before quoting any oil work.

How long does an oil-to-gas conversion take in Portadown?

Around 6-12 weeks total: 4-8 weeks of Firmus scheduling for the service connection, then 2-3 days on site for boiler removal, tank decommission, pipework and commissioning. Total cost usually £3,500-£5,500.

Do you cover farms on the Lough Neagh side?

Yes, multi-boiler agricultural servicing is regular workload across BT62. We site-visit and quote each system separately so the work can phase across the budget year if needed.
