Manufacturers can still use the CE mark to sell products on the UK market if a mandatory third-party conformity assessment has been carried out by an EU-recognized conformity assessment body, or if the certificate of conformity previously issued by a UK body has been transferred to an EU-recognized conformity assessment body. If a UK notified body was originally used and the conformity assessment dossier was not transferred to an EU notified body before January 1, 2021, the UKCA mark must be used immediately from January 1, 2021, and the CE mark will no longer be accepted.

Products that have been manufactured and put on the market before December 31, 2020 can continue to be sold on the UK market using the existing CE mark.

The UKCA mark will not be recognized in the EU market, and products that currently require the CE mark will still require the CE mark to be sold in the EU.

Products that are considered to be within the scope of mandatory regulatory control will need to have the UK Conformity Assessment (UKCA) mark after December 31, 2020 to enter the UK market, and must contact a UK-recognized third-party body.

Prior to 1 January 2023, the UKCA mark and the relevant importer and manufacturer information may be marked on the product itself or on the documents accompanying the product, except for products to which special rules apply, while after 1 January 2023, it may only be marked on the product itself.

UK Declaration of Conformity

The UK Declaration of Conformity is a document that must be drawn up for most products that legally bear the UKCA mark.

In the document, you as the manufacturer or your authorised representative (where permitted by the relevant legislation) should:

Declare that the product complies with the relevant statutory requirements applicable to the specific product

Ensure that the document contains the name and address of the manufacturer (or your authorised representative), as well as information about the product and the conformity assessment body (if relevant)

The UK Declaration of Conformity will be made available to market surveillance authorities on request.

The information required on the Declaration of Conformity will be largely the same as that currently required for the EU Declaration of Conformity. This may vary depending on the regulation under which you are applying, but should generally include:

Your name and full business address or the name and full business address of an authorised representative

The serial number, model or type identification of the product

A statement that you accept full responsibility for the compliance of the product

Details of the approved body that carried out the conformity assessment procedure (if applicable)

The relevant regulations to which the product complies

Your name and signature

Date the statement was issued

Supplementary information (if applicable)
