An essential guide to UKCA marking and compliance

The UKCA (UK Conformity Assessed) mark is the new UK product mark that will be required for certain products being placed on the market in Great Britain. It covers most products that previously required the CE mark. The UKCA mark will not be recognised outside of Great Britain and products will still need to bear a CE mark to be sold in the EU. CE marking will continue to be accepted in Northern Ireland under the Ireland/Northern Ireland Protocol.

The Rules in Summary:

  • Broadly speaking if you needed CE marking for your goods, now you will need UK Conformity Assessed (UKCA) marking.
  • Where CE marking is currently applied by following the self-certification route, no changes will be required.
  • It also applies to aerosol products that previously required the ‘reverse epsilon’ marking.
  • There are individual guides for, e.g. medical and construction products as well as civil explosives

Northern Ireland:

  • If you are placing goods on the market in Northern Ireland, the CE marking continues for most manufactured goods.
  • If you use a UK body for conformity assessment a UKNI marking is applied. The UKNI never appears on its own – it always accompanies an EU conformity marking, such as the CE marking. Goods with both the CE and UKNI marking cannot be placed on the market in the EU.
  • No changes are necessary if you are a Northern Ireland manufacturer or mark goods based on a supplier’s self-declaration of conformity.
