For what period of time is it legal to keep a French Registered car in England.
If the police stop your vehicle it's up to you to show you can use the vehicle in the UK without taxing and registering here. You may be asked to show proof of the length of time you have been in the UK, such as a ferry ticket or evidence that you and the vehicle are eligible for customs relief.
It is important to remember that if you become a resident in the UK, you must tax and register your vehicle in the UK straight away.
We are returning to the UK in July. We would prefer to take our French car with us and decide later if we would prefer to sell it and buy an English car. We have been informed that our insurance is valid for three months.
