Landlord gas safety certificate in Belfast
Landlord gas safety certificate from HeatNI for homes across Belfast and the surrounding suburbs (BT1–BT17)—real engineers, no resold leads, callbacks from our team.

Landlord gas safety certificate 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 has a large rental sector, especially across the south and east of the city; we issue annual CP12 inspections promptly and keep records on file for landlords.
Letting the certificate lapse isn't just a legal risk—it can affect landlord insurance and cause delays when letting or selling a property. Book a callback with your property address, number of gas appliances, and any access notes. We'll confirm timing and issue the certificate promptly after inspection.

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.

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.
