I am a British citizen travelling to Heathrow on 17th June. I then need to catch another flight to Bulgaria 2 hours later from the same terminal but it's not a connecting flight. These are 2 separate tickets. I have to pass border control to collect my bags and then go to catch another flight. But if I pass border control it is as if I have entered the country. So I am considered a landside transit passenger. Will I be quarantined?
I read all government advice online and there is no such information anywhere. It is not clear!
Please advise
