Economic Operator Registration and Identification (EORI) number for all VAT registered businesses to trade with Europe even under a No Deal Brexit and World Trade Organisation (WTO) trade tariffs.
Expat Advice in Europe After Brexit:
Financial Services Passports – UK regulators have confirmed that EU finance companies will be granted Temporary Permissions to continue to operate in the UK whilst they establish a UK authorised business. Even those firms that do not want to continue trading will be granted a shorter term Temporary Permission whilst they wrap up existing client operations and make an orderly exit
Some EU countries will be granting the same rights to UK financial companies operating in Europe.
If no passport then we will continue to work on the basis that we do already in non-EU countries.
