Hard Brexit consequences
If the UK leaves the EU without a deal one will still, in the majority of cases, be able to use the CE marking to demonstrate compliance with the legal requirements and to sell products on the UK market after 29 March 2019. However, in some cases you will need to apply the new UKCA marking to products being sold in the UK.
The UKCA marking
Most, but not all, products which are currently covered by the CE marking will fall within scope of the new UKCA marking. The rules around using the new UKCA marking will mirror those which currently apply for the application of the CE marking. In most cases you will still be able to use the CE marking. However, if your products require third party assessment of conformity, and if this has been carried out by a UK conformity assessment body, you will have to apply the new UKCA marking after 29 March 2019.
This will not be the case if the certificate of conformity has been transferred to an EU-recognized body based on the application of the CE marking. If you currently rely solely on a self-declaration of conformity for the CE marking you will also be able to use the UKCA marking based on self-declaration, for those products that fall within scope of the marking. What must be taken into account is the UKCA marking will not be recognized on the EU market, and products currently requiring a CE marking will continue to require a CE marking for sale in the EU.
