That one expired Expiry: 15.—(1) These Regulations expire at the end of 20th December 2021. You're right about local rules applying to specific businesses (Sainsburys, TFL etc), I was thinking more England wide. To be honest looking at the cases in Scotland (where mask compliance from Sep-Dec was high) with England (where it wasn't genrally required and few wore them outside of public transport) I can't tell if the rules made any difference at a population level .
