Since 8 June 2015, you need to supply evidence of what vehicles you can drive or confirmation of any penalty points, you can request a unique code from GOV.UK which allows you to share your driving licence details or you can download a summary of your driving licence record. The code lasts for up to 72 hours and will allow the hire companies to make any necessary checks. If you cannot generate a code online then you can call 0300 083 0013 and DVLA will provide you with a code.
Hires must be between 25 and 75.
