Has all social distancing in England now ended?

Officially it has, but you're expected to use your own judgement and be sensible.

Yes, pretty much. Enforcements on masks, distancing etc. have all but ended with a few exceptions (hospitals, GP's, care homes - places with very vulnerable people).

I live in a fairly busy city, and it's similar now to pre-Covid. Restaurant, bars, retail - all open business as usual.

Our cases remain relatively high, but our deaths and hospitalisations have dropped significantly, and that's primarily due to a successful vaccine rollout.
