Bottom line:
The parallel period is not "valid forever," and label changes should be prioritized by SKU
The UK government has repeatedly extended the recognition period for the CE marking in the UK, but parallel recognition is not a permanent arrangement. For sellers exporting to the UK, 2026 should be the year to treat UKCA (UK Conformity Assessed, the local compliance marking replacing CE after Brexit) as a mandatory action rather than waiting for notice.
The practical judgment is simple:
- SKUs already sold in the UK market whose packaging/nameplates bear only CE have the highest priority;
- Long-tail SKUs accounting for less than 5% of UK site sales can be evaluated for "delisting rather than relabeling";
- New products should be designed with UKCA documentation from the start to avoid a second revision.
Step 1: Determine the applicable regulations; do not focus on just one mark
UKCA is not a single regulation but a combination of UK domestic regulations. Common correspondences are as follows (reference ranges; the original text on the UK government official website shall prevail):
Electrical and electronic (safety) — Applicable UK regulation: Electrical Equipment (Safety) Regulations 2016; Relationship with EU regulations: Highly close to the technical content of LVD 2014/35/EU; Common test reuse level: High; reports can be reused; standard versions need to be checked
Electromagnetic compatibility — Applicable UK regulation: EMC Regulations 2016; Relationship with EU regulations: Close to EMC 2014/30/EU; Common test reuse level: High
Radio equipment — Applicable UK regulation: Radio Equipment Regulations 2017; Relationship with EU regulations: Close to RED 2014/53/EU; Common test reuse level: Medium-high; frequency bands and power limits need to be compared item by item
Toys — Applicable UK regulation: Toys (Safety) Regulations 2011; Relationship with EU regulations: Close to Toy Safety Directive 2009/48/EC; Common test reuse level: Medium; the UK adoption status of EN71 series standard versions needs to be confirmed
Machinery — Applicable UK regulation: Supply of Machinery (Safety) Regulations 2008; Relationship with EU regulations: Close to Machinery Directive 2006/42/EC; Common test reuse level: Medium; some harmonized standard versions differ
Hazardous substances — Applicable UK regulation: RoHS Regulations 2012; Relationship with EU regulations: Close to RoHS 2011/65/EU; Common test reuse level: High
Key point: Close technical content does not mean documents can simply be given a new cover. The technical file, the declaration of conformity (DoC, a compliance declaration signed by the manufacturer), the header, UK responsible person information, and cited standard versions required by UKCA all need to be rewritten according to UK requirements.
Step 2: Boundaries between document reuse and rework
Reusable parts (reference ranges):
- Test reports issued by partner laboratories, if the standard versions are consistent with the versions adopted in the UK, can usually be reused;
- Circuit diagrams, BOM, instructions, and critical component lists;
- Risk assessment framework.
Parts that must be redone or supplemented:
- UKCA declaration of conformity (UK DoC), which must list the names of UK regulations and the UK responsible person;
- Nameplates and packaging: UKCA marking proportions, clarity, and traceability information;
- If the product has no UK local responsible party, a UK Responsible Person must be designated (the entity performing compliance obligations in the UK on behalf of the manufacturer).
Fee reference range: For the UKCA document preparation and marking change for a single electronic SKU, the publicly disclosed industry range is approximately RMB 1,500–12,000; projects involving supplementary testing usually fall within RMB 5,000–20,000. The reference lead time is 5–10 working days, extended to 15–25 working days if supplementary testing is required.
Step 3: Document checklist for listing on Amazon UK
Platform review usually requires:
1. UKCA declaration of conformity (PDF, including signatory, date, and UK responsible person);
2. Test report (issued by a qualified partner laboratory);
3. Product label
and the six-sided packaging artwork; 4. UK responsible person information; 5. If it is a toy, a declaration and warnings compliant with UK toy safety regulations are also required. The most frequent reasons for delisting are not "no certificate," but rather the standard version on the DoC being inconsistent with the report, the UKCA mark size on the nameplate being non-compliant, and missing UK responsible person information.
Step 4: Merging Strategy for CE and UKCA For the same product entering both the EU and UK markets, it is recommended to plan at the testing stage in one go: - Choose a standard version adopted by both sides for testing; - Address the report headers separately to the two DoCs for the EU and UK; - Use a "dual-marking" design for packaging to reduce secondary printing costs.

Service boundary: Shuwang Certification Platform is an export certification solution provider. It does not perform testing and is not a certification body. Testing described on this page is carried out by partner laboratories accredited to CNAS/CMA or ISO/IEC 17025; certificates are issued by EU Notified Bodies or by the authorised bodies of the destination country. Lead times and cost ranges are public industry references and depend on engineer assessment and body scheduling.
The takeaway:
For the UK market in 2026, UKCA is not an option to "wait and see," but a systematic engineering task of prioritizing by SKU, reusing test reports first, and then rewriting the DoC and nameplate.
