It is in a grey area and I would not trust that eg a Hungarian license issued while you are not living in this country for a certain period will be accepted if it comes to real problems. We know this way pretty well in Germany and in particular travels to Poland and the Czech Republic are very popular to get a license for notorious offenders. However, unless you have lived there for a period of (to my recollection) six months these licenses might not be accepted in Germany.

And they even give you the answer:

Q I have been banned (licence revoked) in the UK or elsewhere, can I drive legally in the UK or other countries with one of these licences.

A. No

Q. Why haven't you been shut down by the Police?

Please read the website again, we are NOT doing anything illegal. We are representatives of the applicant only and not responsible if the applicant lies or makes a false declaration! That's the clients business! We do not condone illegal activity. We follow the procedures as dictated by the foreign licensing authorities. Should these procedures change in the countries we operate in, there are another ten Eastern European countries that recently joined the E.U to explore. All with their own unique procedures. Please don't ask us to break laws. Follow the options. Everything is possible.
