Travelling with non household members abroad

[Confusedbutheyho]

Is it allowed?

Country in question is in Europe and likely to have an air bridge. Son has been given an opportunity to go to a private villa in France and is really wanting to go but I’m not sure about the rules.

Bumping as I’d really like to know this too! My exh has booked to take our son away in the middle of July with a few family members (non of who live together). Both exh and one of his older sons have very young babies. I am also pregnant so we have told ds that he will need to quarantine when he gets back but I know my exh and the other family won’t. The annoying thing is that they are only going for the weekend so it seems utterly pointless!

There doesn’t seem to be any advice about it , but I’d hate for my son to get to the airport and turned back!
