DVLA Coronavirus (COVID-19) update:
DVLA are now processing paper applications, however these will take longer
to process as the DVLA are working with reduced staff to meet social
distancing requirements. If your application requires medical information or
examinations there are likely to be delays also.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.
