Hello, Elle!
I think you are wise staying home for now.
It is cold out there, and that will not benefit coughs and colds.
I took my car to give it a run, and my door locks were frozen.
Better hunt out the WD40 and give the locks a wee scoot.
WD means "water dispersant", I think?
I think your answer is (h)Ealing and, yes, it was in recently.
I did not know, at the time, that it was part of London.
I imagined it to be out past Watford or somewhere like that!
Not looked at my own crossword yet.
