New boiler installation in Belfast
New boiler installation from HeatNI for homes across Belfast and the surrounding suburbs (BT1–BT17)—real engineers, no resold leads, callbacks from our team.
New boiler installation in Belfast starts with the right diagnosis, not a sales pitch. HeatNI works from inner-city flats around BT1 and BT2 to family streets in east Belfast (BT4–BT6), the Lisburn Road (BT9), and out toward Stormont and the Castlereagh Hills, and your enquiry comes straight to us—no marketplace, no broker.
Belfast properties span everything from late-Victorian terraces to 1960s estates and modern apartments—each with their own heating quirks. Belfast installs frequently involve removing back-boilers or upgrading to combis; we plan flue routes and condensate drains before a quote.
Select “New Installation” when booking and outline house size, radiator counts, and fuel type if known. We’ll discuss brands, warranties, lead times, and disruption honestly.

How HeatNI pricing works
We quote, then we work
Repairs are diagnosed first, then priced before any parts are ordered. Installations are quoted in writing after a survey—no commitment until you're happy.
Honest about what's included
Our quotes break down labour, parts, disposal, and any flue or pipework changes—so you can compare like-for-like with anyone else you're considering.
No deposit on routine work
For boiler repair, servicing, and emergency callouts you pay on completion. Larger installs may take a deposit toward materials—we'll explain in writing first.
Costs vary by home, boiler model, parts availability and access. We won't guess—we'll quote properly before we book the work in.
Common questions
Do you cover all Belfast postcodes?
Yes—we cover BT1–BT17 for Belfast. Add your full postcode when you book and we'll confirm coverage when we call.
Can I get an instant fixed quote online?
Ballpark figures help budgeting, but compliant installs need verification on site. Photos in your notes help yet never replace a survey.
Are grants available?
Programmes change—ask us and consult official government energy grant guidance when planning capital spend.
