Business travel to the UK
EU, EEA or Swiss Citizens who need to travel to the UK for short business trips i.e. less than 6 months will not need a visa.
The UK’s new point based immigration system means you can continue to visit the UK without applying for a visa and in most cases you can stay for up to 6 months. You can cross the UK border using a valid passport which should be valid for the whole time of your stay.
If the intended business trip will exceed 6 months then you may require a visa. The following link will give you more information about visiting the UK on a business trip and help you establish whether you need to apply for a visa to support your intended business travel.
Driving in the UK
If you have a non-UK licence you can still continue to drive in the UK and you don’t need an IDP (International Driving Permit)
If your vehicle is not insured in the UK you should carry an insurance green card or other valid proof of insurance issued by your insurer which must include: name of the insurance provider, number plate or other identifying particulars of the vehicle and period of insurance cover. If your vehicle is insured in a country outside of the green card scheme, then you’ll also need UK vehicle insurance.
