DVLA Coronavirus (COVID-19) update: DVLA are only dealing with applications from those who are directly involved in the response to the COVID-19 pandemic.
They are unable to deal with any other applications until further notice. Click here for more information.
Whilst technically in law the courts in Poland have no jurisdiction over the UK, this may still be something that DVLA takes issue with. You should speak to them for advice on this specific licensing issue.
There may also, of course, be issues in future with insurance but again is something that would need to be clarified with an individual insurer.
