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.

How long does servicing take?
Often around an hour, depending on appliance type, access, and findings. We’ll confirm expectations when we call.
Is servicing the same as a repair?
