Yes, you can add additional drivers at no extra cost.
Once you've flicked the toggle for additional driver during the booking process, we kindly ask you to come through to our chatbot service which you can find on our app or website, where we can collate the additional drivers details and get them confirmed on the vehicle.
For all UK licences, we require a picture of the front and back of their licence and ask you to retrieve a 'check code' from the following link https://www.gov.uk/view-driving-licence
If this will be a European licence heading our way, then please note we do also require a proof of address that's no older than 3 months.
If this is an International licence then please do send a passport copy over to accompany your licence.
The requirements for additional driver(s) are the same as for the primary driver (see here).
