Yes, that's what I'd heard as well, but looking at the forms from our Local Authority, it doesn't necessarily follow. If you're not receiving these, you can still apply, but they may need further information, such as from the GP. Also, you have to attend in person which is what mum's doing (with my help) next week.
I was really more concerned about this daft "20 meters" thing as mentioned in the initial question. I'll just see what happens, I guess. Thanks for replying.
