A landlord’s guide to gas safety certificates (CP12)
If you let a home with gas, a yearly gas safety check is a legal must. Here’s what the law asks of you, what we check and how to stay ahead of your renewal date.
A CP12 is the name most people use for a landlord gas safety record. Under the Gas Safety (Installation and Use) Regulations 1998, if you rent out a home with gas appliances, you must have them checked every year by a Gas Safe registered engineer.
What the law asks of you
- Have every gas appliance, fitting and flue you provide checked every 12 months
- Give existing tenants a copy of the record within 28 days of the check
- Give new tenants a copy before they move in
- Keep each record for at least two years
- Keep gas pipework, appliances and flues in safe working order between checks
Not having a valid gas safety record is a criminal offence, enforced by the Health and Safety Executive. If a letting agent manages your property, the legal duty still sits with you.
What we check
- A tightness test on the gas pipework to make sure there are no leaks
- Gas pressure and heat input on each appliance
- That each appliance burns safely
- Flues and chimneys, and the ventilation each appliance needs
- Safety devices, such as flame failure devices
- The condition of each appliance and the emergency control valve
Carbon monoxide and smoke alarms
In England, landlords must fit a carbon monoxide alarm in any room with a fixed fuel-burning appliance such as a boiler or gas fire (gas cookers excluded). We test your CO and smoke alarms as part of every landlord check, so you don’t need a separate contractor.
Our landlord gas safety check
£144 inc VAT covers your boiler, hob or cooker and gas fire. Add a boiler service on the same visit for just £54 – £198 inc VAT for both. You get a digital certificate on the day and a reminder when the next one is due.
