Gas Safety Certificate (CP12) for London Landlords

What a landlord gas safety check covers
- Every gas appliance in the property checked for safe operation, such as the boiler, hob and gas fire
- Flues and chimneys checked, along with ventilation where it is needed for the appliance
- Safety devices checked on each appliance
- Your Landlord Gas Safety Record (CP12) issued digitally after the visit
- Any unsafe appliance or fault reported to you clearly. Remedial work is quoted separately, so you decide what happens next
What the law asks of landlords
The Gas Safety (Installation and Use) Regulations 1998 put these duties on anyone who lets a property with gas appliances in Great Britain:
- Have every gas appliance and flue checked for safety once every 12 months by a Gas Safe registered engineer
- Give existing tenants a copy of the record within 28 days of the check, and new tenants a copy before they move in
- Keep each safety record for at least two years
- You can have the check done up to two months before it is due and keep the original renewal date
- Failing to comply can lead to prosecution and unlimited fines, and unsafe gas appliances put tenants at serious risk

Frequently asked questions
How often do landlords need a gas safety certificate?
Every 12 months. You can book the check up to two months before the current certificate expires and your renewal date stays the same.
Do I need a gas safety certificate if the tenants don't use the gas?
Yes. If the property has gas appliances or a gas supply that you provide, the annual check applies. If there is no gas in the property at all, there is nothing to certify.
Who can carry out a landlord gas safety check?
Only a Gas Safe registered engineer who is qualified for the type of appliance being checked. Our engineers are Gas Safe registered.
What happens if an appliance fails the check?
The engineer will tell you what is unsafe and why. Unsafe appliances should not be used until they are fixed. We can quote the remedial work separately, and you are free to arrange the repair yourself.
When do tenants need to receive the certificate?
Existing tenants must be given a copy within 28 days of the check. New tenants must have a copy before they move in.
Can you do a Gas Safety check together with an EICR or EPC?
Yes. Many landlords combine certificates so one booking covers the property. See our landlord compliance packages for the options.
