Now that the formal Brexit withdrawal agreement is agreed, there will be changes to the rules for living, working, travelling and doing business in the UK and EU. These changes are expected to commence at the end of the transition period, from 1 January 2021.

While in the transition, the current rules on trade, travel, and business for the UK and EU will continue to apply.

Much is likely to change from 1 January 2021. This will include rules in relation to healthcare, driving, pet travel and mobile data roaming. For example, the European Health Insurance Card (EHIC) will be valid up to 31 December 2020, but its future remains uncertain after 1 January 2021.

Anyone driving in Europe may also need an international driving permit (IDP) to drive in some countries as well as an insurance 'green card' and a GB sticker.

The existing pet passport scheme will change from 1 January 2021 as will the guarantee of free mobile phone roaming throughout the EU, Iceland, Liechtenstein and Norway.
