CE

CE marking is an administrative marking that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). The CE mark on a product indicates that the manufacturer or importer of that product affirms its compliance with the relevant EU legislation and the product may be sold anywhere in the European Economic Area (EEA) including EU and EFTA.

UKCA

UK Conformity Assessed (UKCA) is a certification mark that indicates conformity with the applicable requirements for products sold within Great Britain (England, Scotland and Wales).
UK certification authorities can not issue EU legal certificates and existing UK certificates are no longer recognised on the EU market. Manufacturers who have previously used legally required certificates from UK authorities must transfer them to institutions within the EU or apply to new institutions.
For products to be released in the EU market, CE certification marks are required as before.
