Landlord Gas Safety Certificates — FAQs
What is a CP12?
CP12 is the common name for the Landlord Gas Safety Record — the document a Gas Safe registered engineer issues after inspecting the gas appliances and flues in a rental property. It must be renewed every 12 months.
Can you deal with my tenants directly?
Yes. Give us the tenant's contact details and we'll arrange access directly, then email the certificate to you and your letting agent once complete.
What if I renew early — do I lose time?
No. If you renew within 2 months of the expiry date, the new certificate keeps the original renewal date, so you never lose coverage by booking early.
What are the penalties for not having a valid CP12?
Failing to maintain a valid landlord gas safety record is a criminal offence that can lead to significant fines, invalidated insurance and, in serious cases, imprisonment. It also blocks Section 21 possession notices in England.
