For a Brussels collection, give the exact street address or agreed meeting point and say whether the pet will be ready indoors, at a residence or at another location. If the collection is outside Brussels, provide the municipality and postcode; “Brussels area” alone is not enough to plan the pickup accurately.
Share passenger numbers, luggage, pet size and the carrier or restraint normally used. If the destination is beyond London, include its full address so the final leg can be assessed as part of the same enquiry. Keep your own travel documents and pet paperwork together, and confirm document requirements with your vet and current official guidance.
The Brussels-to-London page is for travel into the UK. The London-to-Brussels page covers the opposite direction, while the Calais-to-London page is more relevant when the UK-side journey begins after reaching Calais.
