CE marking and UKCA marking: where each applies in 2026

CE marking is the manufacturer's declaration that a product meets applicable European Union legislation — the Low Voltage, EMC, Machinery, and related directives and regulations. UKCA marking plays the equivalent role for products placed on the market in Great Britain, following the UK's departure from the EU. The marks look similar on a label, but they invoke different legal regimes.

For most products the underlying technical requirements are aligned, because UK law was inherited from EU law. That alignment is why many manufacturers test once against harmonized European standards and assemble parallel technical files for both marks. But alignment is not identity: the UK maintains its own designated standards list, and rules on acceptable conformity assessment and marking have continued to evolve separately.

The practical planning question is which conformity assessment route applies to your product. Self-declaration covers many low-risk categories; higher-risk products require the involvement of a notified body (for the EU) or an approved body (for the UK). If your product needs third-party assessment, the certificates and technical documentation must reference bodies recognized in the destination market.

Northern Ireland adds a wrinkle: under the Windsor Framework, goods placed on the market there follow EU rules, including CE marking requirements. Businesses selling into all three territories — EU, Great Britain, and Northern Ireland — should map marking obligations per territory before printing labels.

Marking is the visible tip of a conformity file: risk assessments, test reports, declarations of conformity, and instructions for use all sit beneath it. Authorities in both markets can request the file years after placement on the market, so treat documentation as a living obligation, not a launch task.
