For manufacturers and exporters targeting both the UK (England, Wales, Scotland) and EU markets, there are several differences in document preparation between UKCA and CE requirements. This article explains the technical file structure, conformity routes, notified body roles, and labeling requirements to help companies align their document preparation direction. Applicable products include electrical and electronic equipment, toys, personal protective equipment (PPE), machinery, gas appliances, and other product categories covered by UKCA and CE regulations.

Core Differences: Technical File Structure and Conformity Routes

The core modules of technical files for UKCA and CE (such as product description, design drawings, risk assessment reports, test reports, and declarations of conformity) are generally consistent, but declarations must be issued separately as UK DoC (UK Declaration of Conformity) and EU DoC. The CE route follows applicable EU regulations (e.g., EMC Directive, LVD Directive, RED Directive, etc.), while the UKCA route follows the corresponding UK Statutory Instruments (SI). If the product has no significant changes and the applicable regulations are the same, some test reports or technical files may be shared between the two systems, but it is necessary to verify whether the standard version covered by the report is recognized by the UK.

Differences in Notified Body Roles

Under the CE route, the need for a Notified Body depends on the product category and applicable directives; for example, PPE, gas appliances, explosion-proof equipment, and other high-risk products may request Notified Body involvement. Under the UKCA route, since 2023, the UK market accepts conformity assessment by UK Approved Bodies. If a product requires both a CE Notified Body and a UK Approved Body, the document requirements for each procedure should be confirmed separately to avoid mixing. For low-risk products, manufacturers may submit UK DoC and EU DoC based on a self-declaration of conformity, but must ensure the technical file is complete.

Labeling and Language Differences

UKCA Mark and CE Mark

The UKCA mark should be affixed separately to the product, with different sizing and graphic rules (UKCA graphic is vertically oriented, CE is horizontal). When a product complies with both UKCA and CE requirements, the marks may be affixed separately. The CE mark must be accompanied by a CE DoC, while the UK market requires a UK DoC. For translation files: if the UK DoC contains non-English content, it is advisable to provide a reviewed English translation to avoid delays during customs or market surveillance authority review.

Applicable Scenarios: Which Products Need to Pay Attention to These Differences

  • Products sold simultaneously to the UK and EU markets
  • Products falling under categories covered by UKCA regulations, such as PPE, gas appliances, explosion-proof equipment, children’s toys, electronics
  • Products that already hold CE technical files and wish to quickly adjust UKCA files
  • Products intended to be sold through Amazon, Temu, or UK retail channels that require upload of corresponding compliance documents

Common Misconceptions

  1. Misconception 1: UKCA and CE files are fully interchangeable
    Reality: Test reports and technical files may be referenced if the standard versions are consistent, but declarations must be issued separately as UK DoC and EU DoC. Labeling compliance also needs to be confirmed separately.
  2. Misconception 2: A CE report can be directly used for UKCA
    Reality: If a CE report is based on EN standards, it must be confirmed whether that standard has been adopted by the UK as a BS standard or equivalent. The UK may have adopted a different version of some standards, and the scope of the report needs to be verified.
  3. Misconception 3: Low-risk products do not require any document preparation
    Reality: Even when self-declaration applies, a technical file and a declaration of conformity must still be prepared. UK market surveillance authorities may request documentation at any time.

Document Preparation Recommendations: File Checklist

  • Product technical file (design drawings, instructions, component list, etc.)
  • Applicable test reports (covering EMC, LVD, RED, machinery safety, etc., depending on product category)
  • UK DoC (UK Declaration of Conformity)
  • EU DoC (EU Declaration of Conformity, if applicable)
  • UKCA mark artwork and size confirmation
  • If a notified body is involved: UK Approved Body certificate or CE Notified Body certificate (for different markets respectively)
  • Authorized representative information: UK Responsible Person (UKRP) documentation (if the manufacturer is not located in the UK)
  • EU Authorized Representative documentation (if the manufacturer is not located in the EU)

Platform Review Scenarios

When uploading compliance documents to platforms such as Amazon UK, Temu, and SHEIN, they typically request a UK DoC, test reports, label photos, etc. Platform reviewers will check the product identification, applicable regulations, signatory information, etc. in the documents. We recommend preparing clear scanned copies and ensuring the documents are in English or accompanied by translations. Platforms retain the final review authority; this article is for reference in document preparation only and does not constitute a guarantee of platform acceptance.

Risk Notice

Product and regulatory differences may lead to insufficient document preparation or compliance risks, e.g., incorrect determination of notified body route, mismatched standard versions, incomplete translations, etc. The content of this article does not constitute legal or compliance advice. Final market access requirements should be based on applicable regulations, standards, and official guidance from the target market. We recommend consulting a professional testing and certification organization or legal advisor during the document preparation phase.
