Making an EU presence, setting up subsidiary companies in the EU prior to Brexit could offer large regulatory advantages.
As an example, HM Treasury are considering granting the EU financial sector short term access to UK markets in an attempt to protect the UK as a financial centre, however, it is not guaranteed that EU countries are intending to do the same.
In July 2018 the UK Government's white paper laid out a vision of 'third country' status being applied to the UK.
However, it may prove very difficult to negotiate a position with the EU that allows British businesses greater access to the EU market.
Many companies are already setting up subsidiary companies in the EU to gain a local presence within the EU market, this has been particularly noted within the financial sector.
There is still time for your business to do the same.
However, at this point, buying a local business may be the fastest option.
