About the area
What we do in North Belfast.
North Belfast is on the Phoenix Natural Gas network. We see plenty of back-boiler systems still running, usually worth swapping for a modern combi to free up floor space and cut gas bills.
North Belfast's housing runs the full range: inner-city Victorian terraces off Cavehill Road, interwar semis across Fortwilliam and Glandore, post-war Housing Executive in Ballysillan and Glenbryn, and newer private builds around the Antrim Road's outer stretch. The area has a higher-than-average share of unmodernised heating systems: back-boilers behind gas fires, original 1970s radiator layouts, cast-iron pipework. That combination creates steady replacement work: a back-boiler removal plus combi install frees up living room space that North Belfast families often prize for children. The Cavehill Road ridge has larger Edwardian and interwar detached homes where system boilers and cylinders are the norm. CP12 volume is high across the rental stock.

Local considerations
Things to know in North Belfast.
Back-boiler prevalence is higher in North Belfast than most areas. Many Housing Executive homes still have a gas fire with a boiler behind it heating the radiators. These run at 55% to 65% efficiency. Replacement typically cuts gas bills 30% to 40%.
Some Glenbryn and Ballysillan estates still have original galvanised mains pipework. Symptoms are brown water and reduced flow. We replace during boiler or bathroom upgrades.
Antrim Road corridor has substantial HMO and rental stock. Landlord CP12 routing across multiple properties saves portfolio landlords significant time.

Common questions
North Belfast FAQ.
We've got a back-boiler heating our radiators. Can you remove it?
Yes, our most common North Belfast install. Process: remove back-boiler, cap off gas to the fire, fit a modern combi in kitchen or utility, flush and rebalance radiators. Typical cost £2,250 to £2,550 including first annual service and warranty registration.
Our Cavehill property used to run on oil. Can we get gas?
Phoenix has extended coverage in North Belfast significantly. Most Cavehill Road properties are now on gas mains. We'll check your postcode before quoting conversion. Typical full oil-to-gas project runs £3,500 to £4,500 in this area.
The water pressure in our Ballysillan house is low. Is it the boiler?
Usually galvanised mains pipework inside the house is the culprit rather than the boiler. We check at the stopcock and by testing static flow. Replacement of internal mains from stopcock to kitchen runs £350 to £600 depending on routing.
Landlord with 8 HMO properties on the Antrim Road. Can you route annual CP12s?
Yes, exactly the kind of workload we schedule. One day, multiple properties, all certificates issued electronically to you and tenants, records maintained on file.
