UKCA (UK Conformity Assessed) certification is a new product conformity marking introduced after Brexit, replacing the original EU CE marking. It applies to products sold in the Great Britain market (England, Wales, Scotland) and serves to demonstrate that a product complies with relevant UK regulatory requirements.

Key Information Overview

  1. Scope of Application

    • Primarily applies to products sold in England, Wales, and Scotland (Northern Ireland, due to special agreements, may still use the CE marking and follow EU rules).

    • The covered product categories are similar to the original CE certification, including machinery, electrical and electronic equipment, medical devices, construction products, toys, personal protective equipment (PPE), gas appliances, etc.

  2. Implementation Timeline

    • Originally planned to take effect on January 1, 2021, but the transition period was extended multiple times; the final transition period ended on December 31, 2023.

    • Effective January 1, 2024, relevant products entering Great Britain (excluding Northern Ireland) must bear the UKCA marking or cannot be legally sold.

  3. Certification Process
    Similar to the CE certification process, core steps include:

    • Determine applicable regulations: Based on the product type, confirm the UK national standards (e.g., BS standards) to be met.

    • Product testing and conformity assessment: Certain high-risk products (e.g., medical devices) require testing by a UK Approved Body; lower-risk products may be self-declared by the manufacturer.

    • Prepare technical documentation: Includes test reports, design drawings, Declaration of Conformity (DoC), etc., which must be retained for at least 10 years for inspection by UK regulatory authorities.

    • Affix the UKCA marking: The marking must be clearly and permanently affixed to the product itself (or packaging/manual, depending on the product), with a minimum height of 5mm, and must be accompanied by the manufacturer's Declaration of Conformity (DoC).

  4. Differences from CE Certification

    • Different applicable markets: UKCA applies to Great Britain (excluding Northern Ireland), while CE applies to the EU and EEA countries.

    • Different certification bodies: UKCA requires involvement of UK-recognized bodies (UK Approved Bodies) where third-party certification is needed, while CE requires involvement of EU Notified Bodies.

    • Differences in standard details: Certain UK standards may have subtle adjustments compared to EU standards post-Brexit; the latest UK government regulations shall prevail.

  5. Important Notes

    • Northern Ireland market: The CE marking (complying with EU rules) is still accepted, with no additional UKCA marking required.

    • Importer responsibility: If a product is manufactured by a non-UK enterprise, the UK importer must ensure the product complies with UKCA requirements and retain the technical documentation.

    • Misuse of marking risk: Affixing the UKCA marking without proper certification may result in product recalls, fines, and other penalties.
