Temporary car in Transfer of Residence

Hello, I am relocating to the UK from France in a few weeks. Most of the items will arrive through a moving company but we will be driving from France to the UK in parallel with a few items. The car we drive there belongs to our family in France and we intend to drive it back to France in a few weeks (date unknown but definitely in less than 6 months). The moving company told us to include the car in the Transfer of Residence application, but to us this doesn't apply as we are not importing this car to the UK permanently, it is just being used for transit. We cannot answer "yes" to "will we be keeping this good for more than 12 months". Do we need to include the car in the ToR? Can we be asked to justify that the car will be driven back? Thanks in advance!

Hi Lea, 
One of the condition for TOR relief is you must have had the goods in your possession for at least 6 months prior to the date of importation.
Who can claim relief
You can usually use a vehicle with foreign number plates without registering or taxing it in the UK if all of the following apply:
•    you’re visiting and do not plan to live here
•    the vehicle is registered and taxed in its home country
•    you only use the vehicle for up to 6 months in total - this can be a single visit, or several shorter visits over 12 months
You will need to register your vehicle if you want to move it between Great Britain (England, Scotland and Wales) and Northern Ireland. More information below:

Thank you.
