Frequently asked questions about UKCA Marking

7th October 2020

UKCA marking has replaced CE marking as the required certification for products and machinery being sold or supplied to the UK market. UKCA marking came into effect on 1st January, 2021, and from 1st January, 2022, CE marking will no longer be recognised in the UK.

On this page you will find key information about UKCA marking.

What is UKCA marking?

UK Conformity Assessed Marking (UKCA marking) is a new product marking that is necessary for goods being sold on the market in Great Britain (including England, Wales and Scotland). It covers goods that formerly required CE marking.

It should be noted that goods placed on the market in Northern Ireland still require UKNI marking or CE marking.

When should UKCA marking be used?

UKCA marking will be required for goods – such as products, production tools and equipment – which are placed on the GB market. It applies to the vast majority of goods currently covered by CE marking. UKCA marking came into effect on 1st January, 2021.

What if a product already has CE marking?

The UK continues to accept CE marking for a year after the introduction of UKCA marking; up until 1st January, 2022, when CE marking will cease to be valid. It should be noted that CE marking will still be required for products and machinery sold to the European Union (EU) market.

How will UKCA marking be used?

In the majority of cases, UKCA marking is applied onto a product or product packaging. It might also be placed inside a product manual.

How do you apply a UKCA mark?

When applying a UKCA mark:

  • Only the manufacturer or an authorised representative may place a UKCA mark on a product
  • Once attached, the UKCA mark represents your acceptance of full responsibility for a product’s conformity with requirements in relevant legislation
  • The mark must only be used to show product conformity with relevant legislation in the UK
  • No markings or sign which could misrepresent the meaning of the UKCA marking - or its visibility and legibility - may be placed on a product
  • The UKCA mark shouldn’t be placed on products if there is no specific legal requirement to do so


Rules for using the UKCA image

When using the UKCA image for your UKCA mark, the following rules apply:

  • If you enlarge or shrink the size of the mark, the letters which form the mark must still be in proportion to the official version below
  • The UKCA mark must be at least 5mm high, unless otherwise specified in relevant legislation
  • The UKCA mark should be easily visible and readable
  • From 1st January, 2023, the UKCA mark should be permanently attached




What documentation is needed?

UKCA certification requires a series of technical documentation. This Technical File includes record keeping, which should demonstrate that a product conforms with the requirements of the regulations relevant to it. These records include information such as how a product is designed and manufactured; how a product has been shown to conform to relevant requirements; and a UK Declaration of Conformity.


Declaration of Conformity

Most products that bear a UKCA mark will need an accompanying UK Declaration of Conformity. This document can be drawn up by the manufacturer, or an authorised representative such as a UK approved body when permitted. A UK Declaration of Conformity should include:

Information about the manufacturer, product and conformity assessment body

  • Your name and signature
  • Name and full business address of manufacturer or authorised representative
  • Product serial number, model or type
  • Details of the body that conducted the conformity assessment procedure (if relevant)
  • The date of the declaration being issued
  • Any supplementary information needed


A declaration of product conformity with relevant statutory requirements

  • A statement that you take full responsibility for the compliance of the product
  • Details of the legislation that the product complies with, including all relevant UK legislation and UK designated standards
