For current information on Conversion of Community Marketing Authorisations see European Medicines Agency: Marketing Authorisation



The legislation that will come into force in a no-deal Brexit will, subject to being approved by Parliament, automatically convert Community MAs into UK MAs on exit day (so-called ‘grandfathering’).

As stated in the guidance, the Medicines and Healthcare products Regulatory Agency will issue Product Licence (PL) numbers to Community MAs based on the existing UK practice for determining how many separate national licences are needed across a product range. A proposal setting out the allocated PL numbers will be sent to Community MA holders and published in early January 2019.

If your company holds one or more Community MAs and has not received our letter, please email so that we can verify the appropriate contact details.

For more information see our guidance on Converting Centrally Authorised Products (CAPs) to UK Marketing Authorisations (MAs), ‘grandfathering’ and managing lifecycle changes.
