Landlord gas safety certificates in Northern Ireland
If you let a property in Northern Ireland with a gas appliance, the Gas Safety (Installation and Use) Regulations (Northern Ireland) require an annual gas safety check by a Gas Safe registered engineer. You must keep the record and give a copy to your tenant within 28 days of the check.
Most people still call it a CP12. Whatever you call it, the price with us is fixed: £69 per property for up to three gas appliances, including VAT.
Service and certificate in one visit
The gas safety check confirms appliances are safe. It is not a boiler service. Most landlords want both, because the boiler warranty and the tenant’s winter depend on the service.
We do both in one visit for £119 per property. One appointment for your tenant, one record for your files.

Oil-heated rentals
Many rentals outside Belfast heat with oil. There is no CP12 for oil, but your duty to keep the heating safe still applies, and an annual oil service with an OFTEC CD/11 record is how you show it. An oil service for a rental is £89, the same as for a homeowner.
Portfolios
If you have five or more properties, ask about our portfolio rate: To confirm: portfolio rate and terms. We keep every property’s expiry date on one list, so nothing lapses because a record was filed in the wrong folder.
Reminders before anything expires
We remind you before each property’s record is due, so you can book it in good time. To confirm: confirm reminder timing, proposed 30 days before expiry
Tenant access
Getting into the property is usually the hard part. When you book, give us your tenant’s contact details and we will arrange the appointment with them directly, and let you know when it is confirmed and when it is done. To confirm: confirm tenant contact process and missed-access charge
How booking works
- Book online or email [email protected]. Tell us the address, the fuel and the number of gas appliances.
- Choose who arranges access: you or us.
- Get confirmation with the date, time window and price.
What happens after
You get the gas safety record or CD/11 record by email, plus a service record if the boiler was serviced. If anything fails the check, the record says why, and we quote a fixed price for the repair. If an appliance is unsafe, we follow the gas safety rules and make it safe.
What we do not do
We are heating engineers, so we stick to heating. We do not carry out:
- Electrical installation condition reports (EICR)
- PAT testing
- Fire risk assessments
You will need a qualified electrician or fire safety assessor for those.
