Provide the complete destination in Lille or the surrounding area, not only the city name. If someone else will meet the vehicle, include their contact and the time window they can be available. If Lille is a stop before another destination, share that endpoint so the road plan can be considered as one trip.
For the collection review, include your UK address, passengers, luggage and each pet’s size and travel setup. Mention whether the pet is accustomed to a crate or carrier and any comfort needs that affect stops. Keep the animal’s documents and veterinary details ready for your own checks, and confirm requirements with your vet and official guidance before travel.
Lille-to-London is the reverse route. London-to-Calais may be a better comparison when Calais, rather than Lille, is your France destination.
