Does your product fulfill the CE and UKCA marking and DoC?

CE Marking - UKCA Marking

The CE marking indicates that a product has been evaluated by the manufacturer and found to comply with the EU requirements for safety, health, and environmental protection before affixing the CE logo.
This requirement applies to produc
ts produced outside and within the EU. As a manufacturer, you take responsibility for declaring conformity with all requirements

The Blue Guide on the implementation of the product rules 2022 

UKCA marking is used for products marketed in the UK (England, Scotland, and Wales). UKCA marking is suitable for most products where CE marking is possible. The technical requirements of the UKCA marking will depend on the legislation applicable to the product. 

The UKCA marking cannot be used for products sold on the Northern Ireland market.

UKCA marking: conformity assessment

109-102 Déclaration de Conformité EU.png


The EU declaration of conformity is a document for which the manufacturer is responsible for product conformity.


The document must contain all relevant information to identify the Union harmonization legislation accordingly, the manufacturer, the authorized representative, the notified body if applicable, the product, and appropriate reference to harmonized standards or other technical specifications.


Just as the technical documentation, the EU Declaration of Conformity must keep for ten years from the date of placing the product on the market unless the legislation is modified for any other duration and must be up to date. The manufacturer or authorized representative established in the Union shall bear that responsibility.


As for the European Union, the UK declaration of conformity is a document for which the manufacturer and his representative in the United Kingdom are responsible for product conformity.

The United Kingdom declaration of conformity is a document drawn up for most products legally labeled UKCA before being placed on the market. Manufacturers should have the United Kingdom Declaration of Conformity and the EU Declaration of Conformity in separate documents.

The DoC must prove that the product complies with the regulatory requirements and must keep it for ten years from the date of placing the product in the market.

You can continue to place CE-marked products on the GB market until 12/31/2024 as follow:

  • UK regulations amended, you can choose between the UKCA and CE markings until 12/31/2024

  • EU regulations amended, you will need to follow the EU regulation as it applied on 12/31/2020 to supply those goods to the GB market using the CE marking or meet the UK regulation and place a UKCA mark on the product.

Changes effective 12/31/2023, and now extended to 01/01/2025 are as follows:

  • You will need to mark your products with the UKCA logo

  • The appearance of the UKCA Declaration of Conformity

  • Update your technical file to include UK regulations when referring to EU directives

What About Northern Ireland?

There are special arrangements for Northern Ireland where the land border with The Republic of Ireland has been a singular point in Brexit negotiations. As a reminder, the UK is the United Kingdom of Great Britain and Northern Ireland. The independent Republic of Ireland remains an EU member. Great Britain is the countries of England, Scotland, and Wales.


UKNI marking

The UKNI marking is a new conformity marking for products placed on the market in Northern Ireland that has undergone mandatory third-party conformity assessment by a body based in the UK. 
The Northern Ireland Protocol came into force on 1 January 2021. As long as it is in force, Northern Ireland will align with all relevant EU rules relating to the placement on the market.
