I read somewhere that the government had issued a draft plan to businesses and trade unions yesterday (and they had to comment - by yesterday). But I've not seen the document anywhere. Maybe that's what Buzzfeed has its info from.
As for sanitiser for lift buttons, am I the only one who started using my elbow to press buttons on trains, lifts, pelican crossings some weeks before lockdown?
Not sure how you can use contactless to pay a hotel bill unless it's VERY cheap.
Asking that households leave all internal doors open I'd have thought you'd do the opposite. You sit in one room away from the trades(wo)man and let them get on with the work with the door closed. Or do they mean so s/he doesn't need to touch any door handles?
