9.923 Checkatrade reviewsWhat the gas safety check involves
The check is a defined set of safety tests on every gas appliance and flue in the property. We work through each one and record the result.
- Gas tightness test on the installation
- Appliance gas rate and operating pressure checked
- Flue flow and spillage tests to confirm safe venting
- Ventilation checked against the appliance requirements
- Safety devices and controls tested
- Visual inspection of pipework and appliance condition
- Any defect recorded, explained and made safe
- Gas safety record issued for your files and your tenants
What landlords are legally responsible for
As a landlord you must arrange an annual gas safety check on each gas appliance and flue, keep a record of it, and give copies to your tenants — within 28 days for existing tenants, and at the start of the tenancy for new ones. You must also make sure all gas work is done by a Gas Safe registered engineer.
We keep it simple: we do the check, hand you the record and remind you when the next one is due, so nothing lapses.
Homeowners and gas safety checks
You do not need a certificate as a homeowner, but a gas safety check is still a sensible thing to have — particularly when buying a property, after any gas work, or if you have never had the appliances looked at.
If you smell gas, leave the property, open doors and windows and call the National Gas Emergency Service on 0800 111 999 before ringing anyone else.

Frequently Asked Questions
How often do landlords need a gas safety check?
Every 12 months. The law requires an annual gas safety check on every gas appliance and flue in a rented property, carried out by a Gas Safe registered engineer.
What is a CP12?
CP12 is the common name for the landlord gas safety record — the document you receive after the annual check. It lists each appliance inspected and whether it passed.
Do I have to give the certificate to my tenants?
Yes. Existing tenants must be given a copy within 28 days of the check, and new tenants must receive a copy at the start of the tenancy.
What happens if an appliance fails?
We record it, explain the problem and make the situation safe. If the appliance is unsafe it must not be used until it is repaired. We can quote for the repair and reissue the record once it passes.
Do you cover multiple properties?
We do. If you have several properties in Cardiff we can arrange the checks together to keep it simple and keep your renewal dates aligned.
Is a gas safety check the same as a boiler service?
No. The safety check confirms appliances are safe to use; a service cleans and maintains the boiler so it keeps running efficiently. Many landlords book both at the same visit.
