When used for a gas appliance, this label/mark is called the Gas Safety Compliance label, and when used for gas installation work it is called the Gas Authentication Mark.
Gas safety compliance label
The Regulations require gas appliances to be labelled with the gas safety compliance label. It must be:
- no smaller than 15mm in height
- be permanently affixed to the appliance
- clearly visible to the installer
- as near as possible to the model identification of the product.
Gas authentication mark
The authentication mark must appear on both the Certificate of Compliance (CoC) and the Gas Safety Certificate (GSC) to show that these are legitimate documents. However, if the CoC and GSC are combined, the mark only needs to appear once.
