UKCA vs CE Marking — What Non-EU Manufacturers Need for EU and UK Market Access

Since Brexit on 1 January 2021, the United Kingdom has its own product marking system — the UKCA (UK Conformity Assessed) mark — separate from the EU CE mark. For medical device manufacturers selling in both markets, this creates two separate compliance pathways. Understanding the differences, the deadlines, and what is accepted where is critical to avoid costly mistakes.

The fundamental difference

The CE mark allows products to be sold across all 27 EU member states. The UKCA mark allows products to be sold in Great Britain (England, Scotland and Wales). Northern Ireland continues to accept both CE marking and UKCA marking under the Windsor Framework, making it a special case.

A CE mark alone is no longer sufficient to sell in Great Britain. A UKCA mark alone is not accepted in the EU. If you want to sell in both markets, you need both marks — or you need to use the CE mark transitional recognition that the UK has extended.

CE mark vs UKCA mark — key differences

The UK transitional arrangement — what it means for you

The UK government has extended recognition of the CE mark for medical devices in Great Britain. This means CE-marked medical devices can continue to be sold in Great Britain without a UKCA mark — but only under specific conditions and only for a limited transitional period. The UK has been extending this deadline repeatedly, most recently to 2028 for most device classes.

However, this transitional recognition does not mean you can ignore UKCA indefinitely. If you plan to sell in Great Britain long-term, you should be planning your UKCA pathway now, even if the immediate deadline pressure has been reduced.

What non-EU manufacturers need for each market

To sell in the EU (all 27 member states)

• EU Authorized Representative (mandatory under EU MDR Article 11)
• EUDAMED registration — mandatory from 28 May 2026
• Technical documentation meeting EU MDR Annex II and III requirements
• CE mark on label
• EU AR name and address on label (EC REP symbol)

To sell in Great Britain

• UK Responsible Person (UKRP) — mandatory for all non-UK manufacturers
• MHRA device registration
• Technical documentation meeting UK MDR requirements (currently very similar to EU MDR)
• UKCA mark on label (or CE mark during transitional period)
• UKRP name and address on label

Northern Ireland — the special case

Under the Windsor Framework, Northern Ireland continues to follow EU rules for goods placed on the Northern Ireland market. This means CE-marked medical devices can be sold in Northern Ireland without UKCA marking, and EU MDR applies rather than UK MDR. For manufacturers selling into Northern Ireland, the EU compliance pathway is sufficient.

Should you get CE marking or UKCA first?

For most non-EU manufacturers, the answer is clear — EU MDR CE marking first. The EU market of 450 million people is significantly larger than Great Britain's 67 million. EU MDR technical documentation is also more comprehensive, meaning your EU dossier forms a strong foundation for UKCA if and when you pursue it.
