UKCA Marking: Complete Guide for UK Market Access in 2025

UKCA (UK Conformity Assessed) marking is the product marking required for goods placed on the market in Great Britain. This comprehensive guide covers everything manufacturers need to know about navigating post-Brexit product compliance in the UK market.

What is UKCA Marking?

UKCA marking demonstrates that products comply with UK regulations and standards. It came into effect on January 1, 2021, following Brexit, and replaced CE marking for the UK market.

The UKCA marking represents the UK's independent product safety and compliance framework. While initially designed to closely mirror CE marking requirements, the UK retains the ability to diverge from EU regulations over time. Understanding UKCA requirements is essential for any manufacturer selling products in Great Britain.

Legal Basis

UKCA marking is established under:

• The Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019
• Various UK statutory instruments implementing product-specific requirements
• UK designated standards (many initially aligned with EU harmonized standards)

The marking applies across England, Scotland, and Wales (collectively "Great Britain"), but not Northern Ireland, which follows different post-Brexit arrangements.

When Do You Need UKCA Marking?

UKCA marking is required for products previously requiring CE marking that are sold in:

• England
• Scotland
• Wales

Important Note: Northern Ireland follows different rules under the Northern Ireland Protocol and continues to use CE marking for goods on the Northern Ireland market. Products moving between Northern Ireland and Great Britain may require both markings depending on the supply chain.

Product Categories Covered

UKCA marking applies to products in the same categories that previously required CE marking:

• Toys
• Recreational craft and personal watercraft
• Simple pressure vessels
• Electromagnetic compatibility
• Non-automatic weighing instruments
• Measuring instruments
• Lifts
• ATEX equipment
• Radio equipment
• Pressure equipment
• Personal protective equipment
• Gas appliances
• Machinery
• Outdoor noise
• Ecodesign
• Aerosols
• Low voltage electrical equipment
• Medical devices

UKCA vs CE Marking: Key Differences

Understanding the distinctions between UKCA and CE marking is crucial for compliance strategy:

Aspect	UKCA	CE
Geographic scope	Great Britain (England, Scotland, Wales)	EU/EEA member states
Legal basis	UK regulations and statutory instruments	EU directives and regulations
Standards	UK designated standards (currently mostly aligned)	EU harmonized standards
Conformity assessment	UK approved bodies	EU notified bodies
Recognition	Only in UK (not recognized in EU)	Across EU/EEA (not recognized in UK for new products)
Authority	UK government departments	European Commission
Database	No centralized UK equivalent to NANDO yet	NANDO database for Notified Bodies

Practical Implications

For manufacturers selling in both markets:

• Need to maintain two sets of compliance documentation
• May require testing/certification from both UK and EU bodies
• Must track diverging requirements over time
• Need dual marking strategy
• Increased compliance costs and complexity

For UK-only manufacturers:

• Can focus solely on UK requirements
• May benefit if UK regulations become less stringent
• Simpler compliance pathway than dual compliance

For EU-only manufacturers:

• No need for UKCA marking
• Lost automatic UK market access
• Need to reassess UK market strategy

Transition Periods and Deadlines
