And apparently, if you're a landlord with say ten properties, then you, as the property owner will get the £4000, not the tenants. So it seems to presently a matter of personal moral ethics / choice whether said landlord passes said grants onto their tenants.
On a lighter note, many years ago when my late ex was putting me though a particuarily nasty divorce, she tried to stitch me up into paying a lot of back council tax on the 'former marital home' in which she still resided. Went to the CT office and it transpired, no idea how, that they owed me 49p. - ! I said to the nice manny I'd let them off that one - !
