Who needs a gas safety certificate

Landlords All landlords of residential properties with gas appliances must hold a valid annual gas safety certificate or risk prosecution and an unlimited fine.
Landlords renewing tenancies A new certificate must be issued within 12 months of the previous one — tenants must be provided with a copy before or at the start of each new tenancy.
Homeowners selling a property While not legally required, a gas safety certificate provides buyers with independent confirmation that all gas appliances are safe and correctly installed.
Homeowners with aging gas appliances If your boiler, cooker, or gas fire is over 10 years old and has not been recently inspected, a safety check provides peace of mind and can identify any risks early.
HMO owners Houses in Multiple Occupation have additional compliance requirements — all gas appliances must be certificated and records kept for a minimum of two years.

Frequently asked questions

Landlords must renew the CP12 every 12 months. Failure to hold a valid certificate is a criminal offence and can invalidate property insurance. Reion covers the full Southwark area for annual landlord gas safety inspections.
A standard gas safety inspection for a property with one boiler typically takes around 45 minutes. Properties with multiple appliances — gas hob, fireplace, additional boiler — take longer. Reion confirms expected duration when you book.
If an appliance is found to be unsafe, Reion advises on whether it can be made safe immediately or needs to be isolated pending repair. A certificate cannot be issued until all appliances are confirmed safe. A clear explanation and quote for remedial work will be provided.
