About the area
Ten-plus years of Belfast boilers. We know the quirks of every postcode.
Most of Belfast is on the Phoenix Natural Gas network, so gas boiler installs and servicing make up the bulk of our work here. The city's housing mix means we see everything from compact BT15 combis to full system boilers with unvented cylinders in larger BT9 properties.
Belfast's housing market spans four distinct tiers. The inner red-brick terraces in BT4, BT5, BT12 and BT15 were built between 1890 and 1920 and still account for a huge share of our call volume, usually for combi swaps where the old boiler has outlived the warranty. South Belfast (BT7, BT8, BT9) has larger Edwardian and interwar detached homes where system boilers with 180-300L unvented cylinders make sense for multi-bathroom households. The council estates of BT11, BT12, BT13 and BT14 from the 1960s and 70s tend to run 24kW combis with radiator systems that badly need flushing. Newer developments across Titanic Quarter, Gasworks and Lagan Wharf are on underfloor or mixed systems entirely.

How we work here
What Belfast homes need.
Every area has its own housing stock and heating mix. Here's how that shapes the work we do in Belfast.
Housing stock
Victorian and Edwardian red-brick terraces dominate the inner city. Interwar semis line the main arterials (Antrim Road, Ormeau, Castlereagh, Falls). Post-war council housing fills the outer boroughs. Newer riverside apartments in the city centre and Titanic Quarter.
Heating pattern
Around 85% Phoenix Natural Gas coverage. Combi boilers dominate smaller terraces and estates. System boilers with unvented cylinders are standard in larger BT9 and BT4 homes. A handful of oil boilers remain in unmodernised outlying properties.
Common jobs in Belfast
- Combi boiler replacement in Victorian terraces, Worcester Bosch and Ideal Logic as common choices.
- Power flushing on 1960s to 80s estate systems with decades of sludge.
- System boiler with unvented cylinder installs in South Belfast for multi-bathroom homes.
- Landlord gas safety certificates across Queen's Quarter and Holylands rental stock.
- Oil-to-gas conversions in the few remaining off-grid properties.
- Bathroom installations in mid-terraces where owners are modernising.
- Emergency burst-pipe call-outs in winter, particularly in older stock with exposed pipework.
Local considerations
Things to know in Belfast.
Belfast mains pressure varies hugely by postcode. BT7 and BT8 typically 3 to 4 bar, parts of BT11 and BT12 barely 1.5 bar. That directly affects whether a combi is viable or whether a system boiler is the right answer.
Many Victorian terraces still run cast-iron radiators. Flushing is delicate: aggressive chemicals can lift century-old paint and open seeping joints. We use heritage-safe flush processes on period stock.
Landlord CP12 turnaround matters in the Queen's Quarter student market. We run portfolio routes that fit the academic year turnover.

Common questions
Belfast FAQ.
Which Belfast postcodes do you cover?
All of them, BT1 through BT16. Same-week for standard work, same-day for emergencies regardless of which quadrant of the city you're in.
We've got an old system in a Victorian terrace. Should we repair or replace?
If the boiler is 12 or more years old, sludge is likely system-wide and any repair is a short-term fix. In our experience, a full power flush plus a new combi (around £1,950 to £2,450 fitted in Belfast) pays back in two winters on gas bills alone.
Our mains pressure is poor. What are the options?
In parts of BT11, BT12 and BT13 mains pressure won't support a combi running a power shower. In those cases we recommend a system boiler with an unvented cylinder, or a mains booster. We'll test flow rate during the home survey before quoting.
Do you do commercial gas work in the city centre?
Occasionally, but our focus is domestic. For larger commercial jobs in BT1 or BT2 we'll recommend a specialist from our network.
