I have also been waiting to start PPL, staring enviously at adsbexchange.com. Was pleased to see this morning that North Weald is planning to start back up on 4th July. However I note that DfT hasn't changed its GA guidance yet re. dual instruction.
But given that driving lessons will be OK from 4th July, one would assume/hope that this will soon be updated to permit flight training too? Seems reasonable given that the conditions are the same i.e. one instructor seeing multiple people per day, sharing a small box for >= 1hr. I'm not trying to be an armchair epidemiologist - flying forums have enough of those!
Just thought it was worth pointing out.
Assuming all goes ahead as planned I'll be interested to see what availability is like over summer, especially at weekends - presumably there's a backlog of students!
