Domestic Gas Safety Certificate
A domestic gas safety certificate records the checks a Gas Safe registered engineer carries out on gas appliances and their associated pipework and flues in a home. It gives the householder written evidence that appliances have been tested and left in a safe condition.
The checks reflect the duties set out in the Gas Safety (Installation and Use) Regulations 1998, which require gas work to be carried out safely by a competent registered engineer.

When it's required
A domestic gas safety check is good practice whenever gas appliances are installed, serviced or need reassurance that they are operating safely. Many homeowners request one after buying a property or when they suspect a fault.
The work must be carried out by a Gas Safe registered engineer. Only a registered engineer may legally work on gas appliances and pipework, and the certificate should record that engineer's registration details.
While an annual check is a legal duty for landlords, homeowners are not legally required to hold a certificate. Regular checks are strongly recommended to keep appliances safe and efficient.
