UKCA Marking Requirements for Amazon UK Sellers: What You Need to Know in 2026

If you sell physical goods on Amazon.co.uk, UKCA marking requirements now apply to most regulated product categories. CE marking — which covered the UK market alongside the EU until the end of 2024 — is no longer accepted for products first placed on the Great Britain market. This guide explains what UKCA is, which products need it, how it differs from CE marking, and what you need to do to keep your Amazon UK listings active in 2026.

What UKCA Marking Is and Why It Exists

UKCA (UK Conformity Assessed) is the UK's product conformity marking, introduced following the UK's departure from the European Union. It applies to products placed on the market in Great Britain — England, Scotland, and Wales. Northern Ireland operates under different rules and is not covered by UKCA (more on this below).

Before Brexit, CE marking covered both EU and UK markets under a single regime. After Brexit, the UK implemented its own marking system by transposing EU product directives into UK law through a series of statutory instruments, most significantly the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019 (SI 2019/696).

The UK initially accepted CE marking as a transitional measure. That transition period ended on 31 December 2024 for most regulated product categories. From 1 January 2025, UKCA marking is required for products first placed on the GB market. If you are newly listing a regulated product on Amazon.co.uk in 2026, CE marking alone is not sufficient.

Which Products Fall Under UKCA Marking Requirements?

UKCA marking requirements apply to the same product categories that previously required CE marking in the UK market. Key categories under specific UK statutory instruments:

• **Electrical equipment** — Electrical Equipment (Safety) Regulations 2016 (SI 2016/1101)
• **Electromagnetic compatibility** — Electromagnetic Compatibility Regulations 2016 (SI 2016/1091)
• **Radio equipment and wireless devices** — Radio Equipment Regulations 2017 (SI 2017/1206)
• **Machinery** — Machinery (Safety) Regulations 2024
• **Personal protective equipment** — Personal Protective Equipment (Enforcement) Regulations 2018
• **Toys** — Toys (Safety) Regulations 2011 (as amended)
• **Medical devices** — UK Medical Devices Regulations 2002 (as amended)

If your product falls under any of these categories and you sell it on Amazon.co.uk, UKCA marking applies.

Amazon enforces UKCA compliance for regulated product categories through its UK Regulatory Compliance Portal in Seller Central — similar to how Amazon EU enforces GPSR compliance on EU marketplaces. Listings that do not satisfy UKCA requirements face suppression.

The Northern Ireland exception. Northern Ireland is not part of the UKCA regime. Under the Windsor Framework, Northern Ireland remains aligned with EU product safety law. Products sold in Northern Ireland must carry CE marking — not UKCA. Sellers targeting both Great Britain and Northern Ireland need to understand which marking applies to products destined for each territory. A product sold across both markets can display both CE and UKCA marks on the same packaging, but the underlying compliance documentation is separate.

UKCA Marking Requirements vs CE Marking: What Actually Changes

The UKCA system follows the same conformity assessment logic as CE marking — identify applicable regulations, demonstrate compliance through testing and documentation, issue a declaration of conformity, and affix the mark. The principle is identical. The bodies and the paperwork differ.

UK Approved Bodies vs EU Notified Bodies. For product categories where third-party conformity assessment is required, CE marking uses EU Notified Bodies and UKCA requires UK Approved Bodies. These are separate, independently accredited bodies. An EU Notified Body certificate issued after December 2024 does not satisfy UKCA requirements and cannot be cross-recognised for UK purposes.

UK Declaration of Conformity (UK DoC). UKCA requires a UK Declaration of Conformity referencing UK statutory instruments — not EU directives. A UK DoC is structurally identical to an EU DoC: product identification, manufacturer details, applicable legislation, standards applied, and a signature. The difference is that the legislation column lists the UK SI number, not the EU regulation.

UK-specific labelling. The UKCA mark must appear on the product, its packaging, or accompanying documentation where product size prevents direct marking. Where a UK Approved Body was involved in the assessment, their identification number must follow the UKCA mark. UK Responsible Person contact details must also appear on the product or packaging (see below).

The common mistake sellers make. CE marking and UKCA are now parallel requirements for sellers in both markets. From January 2025, they are entirely separate processes — separate technical files with UK-specific regulation references, separate declarations, separate marks. The underlying test reports may often be reusable for both, but the documentation must be formally completed for each market independently.

For full details on CE marking requirements and how they interact with UKCA for dual-market sellers, see the [CE marking requirements checklist](/resources/blog/ce-marking-requirements-checklist-2026).

The UK Responsible Person: The GPSR Parallel

If you are not established in Great Britain, you almost certainly need a UK Responsible Person (UKRP) to place regulated products on the GB market. The UKRP requirement follows from the same legislative package that introduced UKCA — and mirrors the EU Authorised Representative obligation under GPSR for EU market access.

A UKRP must:

• Be based in Great Britain (England, Scotland, or Wales)
• Be named on the product's labelling with full contact details
• Hold the technical documentation for at least 10 years from the last date of manufacture
• Act as the primary point of contact for UK market surveillance authorities (the Office for Product Safety and Standards — OPSS)

If you are a US, EU, Chinese, or Australian seller listing regulated products on Amazon.co.uk without a GB-established business, you need a UKRP. Importantly, EU establishment does not qualify you. A company incorporated in Germany, France, or the Netherlands is not GB-established. Your UKRP must be incorporated or have a registered address in England, Scotland, or Wales.

SellSafe's audit wizard identifies whether your business location and target market combination requires a UKRP, alongside the full UKCA requirement map — the same workflow as the EU AR check for GPSR compliance.

Meeting UKCA Marking Requirements: The 6-Step Process

1. Confirm your product category requires UKCA. Not all products are regulated. Purely non-technical products without electrical, mechanical, or recognised safety risks may not fall under any UK SI mandating UKCA. Confirm whether your specific product category is covered before starting the process.

2. Identify the applicable UK statutory instrument. Each regulated product category has a specific UK SI with its own essential requirements, conformity assessment routes, and technical file requirements. Start with the SI — it determines everything else.

3. Determine your conformity assessment route. Most product categories allow self-declaration (Module A equivalent), where the manufacturer assesses conformity internally. Some categories — including certain PPE, some machinery classes, and medical devices — require third-party assessment by a UK Approved Body. Do not assume Module A is available without checking the specific SI.

4. Prepare or update your technical file with UK-specific references. If you already have a CE marking technical file for this product, you need a UK-specific version. The underlying test reports may be reusable. The documentation must reference UK statutory instruments and UK-designated standards. A CE technical file with EU regulation references does not satisfy UKCA requirements.

5. Issue a UK Declaration of Conformity. Sign a UK DoC referencing the applicable UK SI, the UK-designated standards applied, and the conformity assessment procedure followed. Retain this document and produce it within 10 days when market surveillance authorities request it.

6. Apply UKCA marking and include UKRP contact on packaging. Affix the UKCA mark and include UKRP name and address on your product or packaging. If you sell in both EU and GB markets, a combined CE + UKCA label is permitted on the same packaging — the documentation files remain separate.

Check Your UKCA Compliance Position

The SellSafe audit wizard asks for your product category, target markets (EU, UK, or both), and business location — then generates a compliance requirement map covering UKCA marking, CE marking, GPSR, and any additional applicable regulations.

For Amazon UK sellers managing EU and UK compliance simultaneously, the wizard shows exactly which requirements apply in each market and what documentation you need to produce. No need to navigate separate OPSS and UKAS guidance.
