Actually, almost all jobs have to requalify if they want to work in Europe. Services are not part of the TCA and therefore professional qualifications are not recognized in the EU. Want to be an architect in the EU? Well, sit all your exams in the EU again, provide EU work experience (usually done as an intern) and so on. The UK wanted to be out of the EU, and they are now out. They have the same standing and the same rules applied to them as any other third country. In fact, most of those barriers were written into the EU rules by UK experts, so the UK should be very much aware of those problems, they designed them.
