The Government is starting a new scheme to shorten quarantine for those returning to UK from abroad. Covid test from one of a list o approved private centres after five full days of quarantine. If negative, quarantine can end.
You can sign up to this from 15th December. Today is 14th December.
However, as far as I can see the list of approved test centres has not been published so no idea if this is feasible.
Anyone seen a list I have missed?
