British driving licence
Exchanging a foreign driving licence to a full UK driving licence is an easy procedure. However, you do not necessarily have to change your foreign licence. If you hold a full, valid driving licence from another EU country, you can drive in Great Britain until you’re 70 without exchanging your licence. You can only drive in Great Britain with a non-EU licence for 12 months after you arrive.
The most popular reason of exchaning foreign driving licence is it can be accepted as a proof of address, but not as a identity document. However, to apply for a UK driving licence, you must be a residence of the UK, which means you have a permanent address in Great Britain that you’ve lived in for at least 185 days.
Application form can be ordered from the government website for free. You need to fill in the application form, attach a photo, your original current driving licence and identification document such as passport or ID card. The fee of £43 should be paid by check or card. Post the application pack to Driver and Vehicle Licensing Agency (DVLA), the address can be found on the application form. You should get your new licence with your original ID document within 3 weeks.
