New boiler installation in Donaghadee
New boiler installation from HeatNI for homes across Donaghadee and the BT21 coastline (BT21)—real engineers, no resold leads, callbacks from our team.

New boiler installation in Donaghadee starts with the right diagnosis, not a sales pitch. HeatNI works from the harbour and lighthouse through the town centre and out toward Millisle and Ballycopeland, and your enquiry comes straight to us—no marketplace, no broker.
Donaghadee is a coastal town with a mix of period harbour-side properties and modern bungalows—salt air is a real factor in heating system longevity here. Stainless-steel flue options are worth discussing for Donaghadee seafront properties where standard terminals corrode faster.
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 Donaghadee postcodes?
Yes—we cover BT21 for Donaghadee. 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.
