How HeatNI pricing works
We quote, then we work

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.

What is a landlord gas safety certificate?
It's an annual legal requirement for landlords renting properties with gas appliances. A qualified engineer inspects all gas appliances and flues, then issues a Gas Safety Record (CP12) confirming they are safe.
How often do I need a gas safety certificate?
Every 12 months. The inspection must be done by a suitably qualified gas engineer. Letting the certificate lapse puts you in breach of your legal obligations as a landlord.
