Would you go on holiday to Germany in early September? It's for family wedding, which is going ahead.
My main concern is:
Will there be 2 week quarantine on return to UK? I have DC back in school on the 7th September 2020 which I don't want them to miss.

Don't go. There will be quarantine and DC will miss school.
Yanbu
Go. It'll be fine.
