Grandparents travelling from abroad

[Rouxmac]

I'm not sure if this is the right section for this, but I haven't been able to find any advice on the .gov website and I'm wondering if anyone else is in a similar situation.
I'm due in November & my son is under 2. My parents live a couple of hours away but with work they won't be able to help out much. My husbands parents are Greek and retired. They want to come over for a month or so to help but we're struggling to find information about Europeans travelling from abroad all the advice is about people from the UK returning home.
It seems at the moment (as long as Greece stays on the Amber list) that they would have to self isolate for 2 weeks when they arrived, which would be fine. But we don't want to trust this info and then find out that they have to pay to isolate in a hotel when they arrive.
Just wondering if anyone else is in the same situation and if they've been able to find any advice?
Cheers

Providing Greece doesn't go on the red list, they don't need to isolate in a hotel. Currently the difference is they aren't exempt from Amber isolation even if double jabbed.

Even if Greece is amber they would need to SI when double vaccinated because they have not been vaccinated in the UK.

Hardly any point even thinking about it until nearer the time as things could change a lot between now and then. If I were them I wouldn't bother booking anything yet.
