A gas safety certificate is an official document that demonstrates that all the appliances and installations in your property have been checked by a licensed engineer to make sure they are safe to use. The flues and gas appliances must be inspected by an experienced engineer each year. This is a legal requirement to prevent carbon monoxide poisoning and other serious accidents. Landlords who do not comply with these regulations may be prosecuted or fined.
Before issuance of the document, gas engineers conduct an extensive inspection to determine the condition of all appliances and installations. The document will state whether the appliances and installations passed or failed, as well as any recommendations for further actions. The certificate will contain the name of the landlord, his address and the date the test was conducted.
There are two kinds of gas safety certificates for domestic and non-domestic. The former is for flats, homes, and studios whereas the latter applies to commercial properties such as warehouses and office buildings. Both certificates must be renewed every year and the engineer must give a copy of each appliance that has been examined.

This includes homeowners who are private as in housing associations, local authorities and hotels and other hospitality venues. Landlords are particularly required to have their homes checked and to provide their tenants with the most current Gas Safety Record, as they are legally accountable for ensuring that their tenants stay safe in the properties they lease or own.
If you own a property and hire an managing agent to take care of your property, it is important to ensure that they're the ones who organize the annual gas safety check. Having a managing agent does not absolve you of your legal obligation to have the property tested and provide your tenants with the most up-to-date Gas Safety Record.
Although it's not an obligation for homeowners to keep their own records of gas safety, they can be helpful when it comes to selling the property as potential buyers will be looking for proof that the appliances are maintained and are safe. The TA6 form that is a part of the conveyancing procedure will also require a record of gas safety and it's recommended to have one before selling.

If any appliances were found to be dangerous they will be labeled as not compliant (NCS) or immediately dangerous (ID) or At Risk (AR).
