Gas Safety Certificates

There are several various kinds of gas safety certificate that may be issued. A lot of them are done when a gas appliance is installed. When many men and women enquire about a “gas safety certification ” it relates to annual safety checks.

Having a gas safety certificate issued yearly for gas appliances is a legal requirement of landlords of residential properties that are leased. This certification is referred to as a Gas Safety Record (CP12). Annual safety checks must be carried out by a professional Gas Safe registered engineer.

An annual Gas Safety Record (CP12) ensures gas appliances at a home adhere to UK gas safety regulations. We believe customers must be provided with a more detailed assessment of their boiler beyond regular safety checks to highlight any potential problems.
