UKCA Marking for Electronics: The Importer's Guide to UK Market Access
UKCA marking electronics UK import requirements explained. Deadlines, responsible person rules, testing labs, and what changes after CE marking acceptance ends.
The UK left the EU in 2020, and its product safety framework went with it. UKCA marking (UK Conformity Assessed) is now the required mark for selling electronics in Great Britain. CE marking, which the EU still requires, is a separate mark for a separate market.
For most importers buying electronics from China, this means you need two sets of documentation to sell in both markets. Here’s what that actually requires.
What UKCA Marking Is
UKCA replaced CE marking for products sold in England, Scotland, and Wales (collectively, Great Britain). It signals that your product meets UK product safety regulations, which are based on the EU directives that existed at the point of Brexit.
The mark itself is simple: the letters “UKCA” in a specific format defined by the Office for Product Safety and Standards (OPSS). The marking must be visible, legible, and permanent. It can go on the product, the packaging, or an accompanying document if the product is too small for a visible label.
One important distinction: Northern Ireland is not covered by UKCA. Products sold in Northern Ireland must carry either CE marking or UKNI marking, depending on whether the conformity assessment was done by a UK-approved body. This is the result of the Windsor Framework, which keeps Northern Ireland aligned with EU product rules. If you’re selling to all parts of the UK, UKCA covers Great Britain and you need separate documentation for Northern Ireland.
The CE Marking Transition Deadline
Here’s where importers have gotten confused. The UK originally set a deadline for ending CE marking acceptance in Great Britain, then pushed it back multiple times.
As of early 2026, CE marking is still accepted in Great Britain under a permanent recognition period that the UK government implemented for certain product categories. The deadline has moved more than once. Before you rely on CE-only marking for your UK sales, check the current OPSS guidance at gov.uk/government/organisations/office-for-product-safety-and-standards. The rules are category-specific, and the grace periods differ by product type.
The practical advice: don’t build your UK distribution strategy around the assumption that CE marking will always be accepted in Great Britain. Get UKCA documentation in place now if you’re doing serious volume in the UK market. Waiting until a hard enforcement deadline is announced puts you in a compliance scramble alongside every other importer who waited.
UK Regulations That Apply to Electronics
UKCA marking is required when your product falls under one or more UK technical regulations. The main ones for electronics importers are:
The UK Radio Equipment Regulations 2017 cover any device that intentionally transmits or receives radio signals: WiFi products, Bluetooth devices, wireless chargers, smart home products, cellular-enabled devices. This is the UK equivalent of the EU Radio Equipment Directive (RED).
The UK Electromagnetic Compatibility Regulations 2016 cover electromagnetic emissions and immunity. Basically any electronic product that could interfere with radio communications or be affected by electrical interference falls here. That’s most electronics.
The UK Electrical Equipment Safety Regulations 2016 cover low-voltage electrical equipment and safety from electrical hazards. Consumer electronics, power supplies, chargers, and similar products fall under this.
A product can fall under multiple regulations at once. A Bluetooth speaker, for example, hits all three. Your Declaration of Conformity must list every regulation that applies.
The Responsible Person Requirement
This is the requirement that catches the most importers off guard.
For CE marking in the EU, the EU has a similar rule requiring an EU-based responsible person. The UK has its own version: every product placed on the Great Britain market must have a UK Responsible Person. This is someone with a registered address in Great Britain (England, Scotland, or Wales) who is legally accountable for the product’s compliance.
If you’re a US or Australian company importing from China and selling into the UK, you can’t just ship products to British customers and stamp UKCA on them. You need either a UK entity (a subsidiary, a UK-based importer of record, or a third-party compliance service) to be named as the Responsible Person.
The Responsible Person’s name, address, and contact details must appear on the product or its packaging. Some importers use UK compliance services that act as their Responsible Person for a fee. This is legal and common. Search for “UK Authorized Representative” or “UKCA Responsible Person service.”
Getting UKCA Testing Done
The good news: testing for UKCA uses the same technical standards as CE marking. The tests are nearly identical, because UK regulations were copied from EU directives at the time of Brexit. If your product has been tested to EN 300 328 for WiFi or EN 55032 for EMC, the same test data can support both a CE Declaration of Conformity and a UKCA Declaration of Conformity.
The difference is in who does the conformity assessment for products that require third-party testing (as opposed to self-declaration).
For EU CE marking, you use a Notified Body (recognized by the EU). For UKCA, you must use a UKAS-approved body (accredited by the United Kingdom Accreditation Service, ukas.com). If your CE testing was done by a European Notified Body, that assessment cannot be directly used for UKCA. You may need to have the assessment reviewed or repeated by a UKAS-accredited lab.
Most major testing houses (SGS, Intertek, Bureau Veritas, TUV Rheinland) have UK-accredited labs that can issue UKCA-relevant test reports. When you brief a lab, specify that you need UKCA-compliant testing, not just CE testing.
Declaration of Conformity for UKCA
You need a UK-specific Declaration of Conformity. You cannot use your EU CE Declaration of Conformity for UKCA, even if the underlying technical standards are identical.
The UKCA Declaration of Conformity must:
Reference the UK regulations that apply to your product (not EU directives). State the technical standards your product was tested to. Identify the UKAS-accredited body that performed third-party assessment, if applicable. Be signed by or on behalf of the UK Responsible Person. Be kept on file for 10 years after the product was last placed on the market.
You don’t submit the Declaration of Conformity to a government body. You keep it yourself and present it if an enforcing authority (HMRC or OPSS) requests it during a market surveillance check or customs inspection.
Marking the Product Correctly
The UKCA mark must be placed on the product, its packaging, or an accompanying document, in that order of preference. If the product is too small to mark directly and there’s no packaging, the document route is allowed.
The mark must be at least 5mm tall. It must be clearly visible and legible. It can’t be hidden behind a panel or printed in a font so small it can’t be read without magnification.
The UK government publishes the official UKCA mark artwork. Download it directly from gov.uk to make sure you’re using the correct version. Don’t have your Chinese factory design their own version.
If your product requires a specific UK-approved body to be involved in the conformity assessment, that body’s identification number must appear alongside the UKCA mark, just as a Notified Body number appears alongside a CE mark.
Selling in Both UK and EU
If you’re importing electronics from China for both the EU and the UK, you need both CE marking and UKCA marking. They’re separate marks, separate Declarations of Conformity, and separate responsible person requirements.
In practice, the testing can largely overlap since the technical standards are the same. One set of test reports can support both declarations. The documentation work is separate, but the lab costs don’t double.
The cost of UK UKCA compliance beyond what you’d already spend on CE marking is primarily administrative. You need a UK-specific DoC, a UK Responsible Person, and if your product category requires a UKAS-accredited body, an additional assessment fee. Budget a few hundred pounds per product line for the additional documentation work, plus the Responsible Person service fee if you’re using a third party.
Enforcement and What Happens at the Border
HMRC checks UKCA compliance at UK ports and airports. OPSS conducts market surveillance after products reach the market. Both agencies have the authority to detain non-compliant shipments, issue improvement notices, and require products to be withdrawn from the market.
The enforcement risk is higher for products in high-risk categories (electrical products, radio equipment, toys, PPE) than for lower-risk categories. But the legal requirement applies across the board.
If you’re selling on Amazon.co.uk or through UK retail channels, note that platform policies increasingly require UKCA documentation for applicable product categories. Amazon has started requesting compliance documentation through its seller portal. Getting your paperwork in order before a marketplace forces your hand is the better approach.
The Practical Path Forward
If you’re already CE-marked for EU sales, you’re closer to UKCA compliance than you might think. The steps are:
Get your existing test reports reviewed by a UKAS-accredited lab to confirm they support UKCA. Write a UK-specific Declaration of Conformity referencing UK regulations. Identify or appoint a UK Responsible Person. Update your product labeling to include the UKCA mark and the UK Responsible Person’s address.
For new products being developed specifically for the UK market, build UKCA into your compliance planning from the start. Brief your Chinese factory on UK labeling requirements early. Factories that export to the EU often have CE marking experience but may have no familiarity with UKCA. Don’t assume they’ll get it right without guidance.
Frequently Asked Questions
Does UKCA apply to products I sell on Amazon.co.uk? Yes. Amazon.co.uk is a UK marketplace, and products sold there that fall under UK technical regulations require UKCA marking. Amazon is increasing enforcement and may request compliance documentation through the seller portal. Having your documentation in order before they ask avoids account holds.
Can I use a CE mark and a UKCA mark on the same product? Yes. If you’re selling in both the EU and Great Britain, you can affix both marks to the product. This is the standard approach for products sold across both markets.
What’s the difference between UKCA and UKNI? UKCA applies to products sold in Great Britain (England, Scotland, Wales). UKNI applies to products sold in Northern Ireland where third-party conformity assessment was required and was done by a UK-approved body. Most importers selling to Northern Ireland use CE marking instead, since Northern Ireland remains aligned with EU product regulations.
Does my Chinese factory need to do anything differently for UKCA? Your factory doesn’t change their manufacturing process. What changes is the documentation and labeling. The factory needs to produce labels with the UKCA mark, reference the UK Responsible Person’s details, and your DoC needs to reference UK regulations, not EU directives. Brief the factory explicitly on these requirements before production.
How much does UKCA compliance cost on top of CE marking? If you already have CE-compliant test reports, the additional cost is mainly administrative. Expect to pay for a UKAS review of your test reports (if needed), a UK-specific Declaration of Conformity, and a UK Responsible Person service if you don’t have a UK entity. Total additional cost is typically a few hundred to a few thousand pounds depending on product complexity.
What happens if I ship CE-only products to the UK after the grace period ends? HMRC can detain the shipment at the border. OPSS can require you to withdraw products from the UK market and issue improvement notices. In serious cases, criminal penalties apply. The practical consequence most importers face first is shipment delays and detention fees while documentation is sorted out.
