From January 1st 2023, the UKCA mark will be required to be displayed on products (except for medical devices - CE marking will continue to be recognized until June 31st 2023). To reduce the impact on businesses, the UKCA mark can be affixed optionally to the product or an enclosed document using a label. This will be accepted until December 31st 2022 only. After this time, the UKCA mark must be affixed directly to the product (unless the applicable regulations make other allowances).
Existing stocks that were fully manufactured and conformity marked prior to January 1st 2023 can still be placed on the British market after January 1st 2023 with a CE-marking and, where appropriate, the number of the Notified Body.
