My employer has been encouraging WFH for a while but mandated it for half our office before government requirement (didn't want everyone in key teams sick at the same time). We have been allowed to buy a monitor and have been supplied with a new laptop; we can also borrow any of the kit we need for the duration (I have borrowed an additional monitor). I moved house last year and chose one within walking distance to work and with an office (personal computer is also there). Tax authority allows tax-free compensation if employer requires WFH but that might complicated tax when house selling.
