Keep your annual gas safety record up to date.
Landlords must arrange a gas safety check every year on each gas appliance and flue they provide for tenants. The resulting Landlord Gas Safety Record is commonly referred to as a CP12 certificate.
As a landlord, it’s your responsibility to make sure your CP12 is current, and your tenants have an up-to-date gas safety record. Landlords are also responsible for keeping the gas appliances, flues and associated installation you provide properly maintained and safe to use.

Landlord service questions.
Common questions from landlords and property managers.
What is a CP12 certificate?
CP12 is the commonly used name for a Landlord Gas Safety Record. It records the annual gas safety checks carried out on relevant landlord-provided gas appliances and flues.
How often does a landlord need a gas safety check?
Landlords must ensure the required gas safety check is carried out every year on each gas appliance and flue they provide for tenants.
When must tenants receive the CP12 / gas safety record?
Existing tenants must receive a copy within 28 days of the check. New tenants must receive a copy before they move into the property.
What happens if a safety defect is found?
Landlords must take prompt action to correct safety defects identified by the check, and an appliance that may be unsafe should not be used until the issue has been remedied.
Can you combine boiler servicing with the gas safety inspection?
Where practical, boiler servicing can be coordinated with the landlord gas safety visit to reduce separate appointments.
Do you support multiple rental properties?
Yes. We can discuss recurring servicing, CP12 inspections, repairs and other property-maintenance requirements for landlords with more than one property.
