UKCA Marking Guide for Electronics: Post-Brexit Certification

UKCA (UK Conformity Assessed) marking was introduced after the UK left the European Union single market, serving as the replacement for CE marking for products placed on the Great Britain (England, Wales, and Scotland) market. For consumer electronics importers sourcing from China — from electric kettles to TWS earphones — UKCA creates a distinct compliance obligation separate from the EU’s CE marking.

While the technical requirements and safety standards largely mirror their EU directive counterparts, the legal framework, responsible body recognition, and market surveillance are entirely separate. If you ship the same product to several regions, treat UKCA as one entry in a wider multi-market certification plan that also covers FCC, CE, and PSE. Note that Northern Ireland remains under EU CE rules under the Windsor Framework.

What is the UKCA Mark and Who Regulates It?

UKCA was established under the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019 and subsequent instruments. The UK government’s Office for Product Safety and Standards (OPSS) is the policy owner; enforcement is by Trading Standards authorities in each UK nation.

UKCA applies to Great Britain only — England, Wales, Scotland. Northern Ireland follows the EU regulatory framework under the Windsor Framework (formerly the Northern Ireland Protocol) and accepts CE marking.

CE acceptance timeline: The UK government has repeatedly extended the period during which CE marking is accepted as equivalent to UKCA. As of 2025, CE continues to be accepted for most product categories. Check current OPSS guidance before planning your compliance approach — this policy has changed multiple times and may change again.

For new products entering the UK market, obtaining UKCA marking is the definitive compliant approach regardless of CE acceptance extensions, as the policy uncertainty creates risk.

UK Regulations Applicable to Electronics

UKCA applies to the same product categories as CE for the GB market. For electronics, the three key UK regulations mirror their EU directive counterparts:

The RoHS equivalent is the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012 (SI 2012/3032), as amended by UK REACH and the WEEE Regulations 2013.

Essential UKCA Compliance Requirements

The technical requirements under UKCA are substantively identical to CE:

Radio Equipment Regulations 2017 (mirrors RED):

• Safety: EN 62368-1 (adopted as BS EN 62368-1)
• EMC: EN 55032, EN 55035, EN 301 489 series (adopted as BS EN equivalents)
• Radio performance: ETSI EN standards adopted as BS EN (EN 300 328 for 2.4 GHz, EN 303 413 for GNSS, etc.)

The UK publishes a list of designated standards in the UK Official Journal — the designated standards reference the BS EN equivalents of EN standards. In practice, all currently harmonized EN test standards have equivalent BS EN adoptions, so test reports from EU-accredited labs citing EN standards are acceptable for UKCA technical files.

Declaration of Conformity: A UK Declaration of Conformity (UK DoC) must be prepared — this is separate from the EU DoC. It must reference UK legislation (the SI numbers), not EU directives. Template requirements are specified in each regulation’s Schedule.

Responsible Person: The importer or manufacturer placing goods on the GB market must be established in the UK or appoint a UK Responsible Person (UK RP) — equivalent to the EU Authorized Representative. UK RP services are available from compliance consultancies in the UK at similar cost to EU Authorized Representative services (£500–2,000/year per product category).

Step-by-Step UKCA Certification Process

Step 1: Determine whether UKCA or CE applies. For Northern Ireland shipments: CE. For Great Britain: UKCA (or CE if current policy still permits it — verify at gov.uk/ukca).

Step 2: Check if existing CE technical file can be reused. If you have an existing CE technical file with test reports from an EU-accredited ISO/IEC 17025 lab, those test reports are generally acceptable for a UKCA technical file, provided:

• Tests were conducted to EN/BS EN standards currently designated under UK regulations
• Reports are from labs accredited by UKAS or equivalent body (UKAS = UK Accreditation Service; EU lab accreditations under EA MLA are generally recognized)

In practice, you can often write a UK DoC referencing UK legislation, based on the same test reports used for your CE technical file, without new testing.

Step 3: Prepare UK DoC. Separate document from EU DoC. References UK regulations (SI numbers), not EU directives. Must be signed by the UK Responsible Person or the manufacturer if UK-established.

Step 4: Label product with UKCA mark. The UKCA mark is a specific symbol (square with “UKCA” text) — different from the CE mark. Both UKCA and CE can appear on the same product if it is sold in both GB and EU markets. Mains-powered devices built for Britain — such as a Type G smart socket — also need the correct UK plug standard alongside the UKCA label. Minimum height: 5 mm. Electronic labeling permitted for small devices per the relevant UK regulation.

Step 5: For conformity assessment with Approved Body involvement. Where EU directives require Notified Body involvement (certain Class II/III medical devices, certain ATEX equipment, certain PPE), UKCA requires UK Approved Body involvement. UK Approved Bodies are listed by OPSS at a dedicated UK government website. EU Notified Bodies are not recognized for UKCA after the transition period.

Timeline: If CE technical file already exists, UKCA compliance can be added in 2–4 weeks (new UK DoC preparation, UK RP appointment, label update). New product: same timeline as CE, 6–12 weeks.

Cost for existing CE-certified products: £500–2,500 for UK RP appointment + UK DoC preparation + labeling update. No new testing cost if CE test reports are accepted.

How to Manage UKCA Compliance When Sourcing from China

For Chinese manufacturers already exporting to the EU, adding UKCA compliance is lower effort than initial CE certification because the technical content is nearly identical. The practical steps:

1. Appoint a UK Responsible Person (various UK compliance consulting firms offer this service at £500–1,500/year per brand/product category).
2. Have the UK RP or your compliance team prepare a UK Declaration of Conformity using your existing CE test reports and technical file, referencing the relevant UK regulations instead of EU directives.
3. Update product labeling and packaging to include the UKCA mark (in addition to CE for dual-market products).
4. Register UK DoC reference number and retain documentation for 10 years.

For new products, run CE and UKCA concurrently — same tests, same technical file content, two separate declarations. The cost is primarily the EU-accredited lab testing, which covers both markets. Our guide to importing electronics into the UK walks through how UKCA documentation ties into customs clearance. Pre-shipment inspection is a good point to confirm UKCA documentation is complete before goods leave China.

Common UKCA Compliance Pitfalls to Avoid

For wearable devices sold into the UK market, UKCA documentation should be reviewed alongside battery and radio compliance before production is approved.

1. Ignoring UKCA because CE is currently accepted. The UK government’s repeated extensions of CE acceptance have created complacency. When the policy eventually changes — and it likely will — products without UKCA documentation will need urgent remediation. Build UKCA compliance now while the technical requirements are identical.

2. Using EU Notified Body certification for UKCA. EU Notified Bodies lost their recognition in the UK after December 31, 2020. For product categories requiring third-party conformity assessment, you must use a UK Approved Body — check the OPSS Approved Bodies list. EU Notified Body certificates are not valid for UKCA.

3. Same Declaration of Conformity for EU and UK. The CE DoC references EU directives; the UKCA DoC references UK regulations (Statutory Instruments). One document cannot serve both — they are legally distinct. Prepare separate documents.
