CE Marking will not be recognised in Great Britain beyond 31st December 2022. CE Marking will continue to be recognised in NI.
To sell a product into the NI market, you will need either a CE Marking (from an EU Notified Body) or a CE and UKNI Marking (from a UK Approved Body).
The UK Government intends to pass legislation to allow goods manufactured in Northern Ireland to be placed on the GB market based on CE Marking post-transition.
