What is a CP12 gas safety certificate and do I need one?

Gas Safety Certificates Southampton


Gas Certificates in Southampton, Eastleigh, Winchester and Romsey.

A landlord gas safety certificate or safety check involves a Gas Safe registered engineer inspecting your gas appliance(s). They will check the appliance is working correctly and will check the following four areas: 

1. Gas appliances are on the right setting and burning correctly with the correct operating pressure.

2. Harmful gases are being removed from the appliance safely to the air outside.

3. That any ventilation routes are clear and working properly.

4. All the safety devices are working.

The check will identify any defects which require remedial work.

Landlord Obligations

You should have a gas safety check every year. If you are a landlord this is the law.

The Gas Safety (Installation and Use) Regulations 1998 say landlords must ensure that gas appliances, fittings and flues are safe for tenant’s use and that installation, maintenance and annual safety checks are carried out by a technician registered with the Gas Safety Register (which superseded CORGI on 1st April 2009).

The landlord must keep a record of the safety check for two years and issue a copy to each existing tenant within 28 days of the check being completed and issue a copy to any new tenants before they move in.

Only use GAS SAFE registered engineers to carry out gas safety checks.
