When to use the UKCA marking
You only need to use the new UKCA marking before 1 January 2022 if all of the following apply. Your product:
· is for the market in Great Britain
· is covered by legislation which requires the UKCA marking
· requires mandatory third-party conformity assessment
· conformity assessment has been carried out by a UK conformity assessment body
This does not apply to existing stock, for example if your good was fully manufactured, CE marked and ready to place on the market before 1 January 2021. In these cases, your good can still be sold in Great Britain with a CE marking even if covered by a certificate of conformity issued by a UK body before 1 January 2021. These goods will need to be placed on the market before 31 December 2021.
