European economic interest groupings (EEIG)

The main features of European Economic Interest Groupings (EEIG) and what information you must register at Companies House.

This publication was withdrawn on

The Brexit transition came to an end on 31 December 2020.

See UK economic interest groupings which replaces this guidance.



This guide tells you what information an EEIG is required to register at Companies House when it is:

  • being formed in the UK
  • moving its official address to the UK from another European Member State
  • establishing a UK office but retaining its official address outside the UK

The guide also tells you when notice of changes to the EEIG’s particulars has to be delivered to Companies House, what forms to use and where to get them.

UK leaving the EU

The UK formally left the EU on 31 January 2020.

Under the terms of the withdrawal agreement between the UK and the EU a transition period started on 1 February 2020 and continues until 31 December 2020.

Read our guidance for information on changes to company registration from 1 January 2021.

During the transition period, the UK is no longer a member state of the EU, but market access will continue on current terms. To give businesses and citizens certainty, common rules remain in place until 31 December 2020.

The legal form of an EEIG is an EU specific entity, established under EU law. The withdrawal agreement means that the UK remains part of the EEIG framework during the transition period.

It is expected that the UK will no longer be able to participate in the EEIG framework after the end of the transition period. So our guidance on changes to company registration will apply for EEIGs from 1 January 2021.
