About the area
What we do in South Belfast.
South Belfast is on the Phoenix Natural Gas network. Larger BT9 properties often run system boilers with hot water cylinders. Bigger cylinders, more bathrooms, more complex heating plans.
South Belfast contains some of NI's most desirable residential streets and a substantial student-rental market that operates on a completely different rhythm. BT9's Malone Road, Stranmillis and Marlborough Park have Edwardian and interwar detached family homes where three to four bathrooms are standard and system boilers with 250L-plus unvented cylinders are the correct spec. BT7's Ormeau is a mix of Victorian terraces and newer conversions. BT8 runs from Newtownbreda out to Finaghy: 1950s to 90s suburban stock. The Queen's Quarter (around BT7 and BT9 border) is dominated by HMO student rentals with a relentless CP12 turnover. Our South Belfast work splits about 40% premium installs (Malone, Stranmillis), 30% student rental CP12 and service work (Queen's Quarter), 30% standard suburban replacements (Finaghy, Newtownbreda).

Local considerations
Things to know in South Belfast.
Student-let CP12 timing is brutal. Every landlord needs certificates renewed and remediation completed before September move-in. We route Holylands portfolios in August specifically for this.
Malone Road's Edwardian villas have complex heating history. Many have been extended, converted, and partially re-piped over decades. Proper pre-install surveying avoids problems later.
BT9's higher-value homes often warrant premium spec boilers (Vaillant ecoTEC Plus, Worcester Greenstar 8000 Life) where warranty and quiet running matter more than upfront cost.

Common questions
South Belfast FAQ.
We own 6 HMOs in the Holylands. Can you do all CP12s before September?
Yes, that's exactly how we route Holylands work in August. We schedule all properties across a day or two, issue certificates electronically, and handle any remediation work while tenants are between contracts. Portfolio rate applies for 5-plus properties.
Malone Road Edwardian detached, 4 bathrooms. What spec?
Typical spec: Vaillant ecoTEC Plus 40 or Worcester Greenstar 8000 Life 50, 250L to 300L unvented cylinder, multi-zoned controls with smart thermostats. Budget £5,000 to £7,500 including Building Control notification and heritage-sensitive commissioning.
Finaghy semi with original 1970s system. Where do we start?
Site visit. Most Finaghy semis can be swapped to a modern combi (Ideal Logic Max 30, Worcester 30i), typically £1,950 to £2,250 fitted. If you have two bathrooms, we may recommend a high-output combi or small system boiler depending on simultaneous use.
Queen's Quarter flat, student tenants. Quick CP12 turnaround?
Same-week booking, single-day certificate, tenants get a copy direct. We understand the student letting calendar and work around move-in dates.
