My mum is in a sheltered extra care flat, which is shared ownership. Some flats in the block are outright owned and some are rented as social housing. The block is run by a housing association, with each flat having a front door and being self contained.
Back in March they requested we didn't visit at all. The carers took the shopping from me in the entrance area and took it to her flat. In early April they advised that it was her flat, private property, they couldn't stop me accessing her flat (I am a key holder)and visits for care purposes were allowed, although only if necessary.
As things moved on, they no longer took mum's food up, and I started taking it in, I don't wear a mask in her flat as otherwise she wouldn't recognize me but I do stay 2 meters away from her, and I don't stay very long, she is very deaf, so communication is difficult, although she is often asleep when I call, and has deteriorated during lockdown.
Last time I was there the housing manager advised that as mum is a single adult household we can create a social bubble with her and therefore as well as visiting her for care purposes she can visit us. I haven't been for a couple of weeks, since before we were Tier 2 and neighbouring areas Tier 3 so I don't know if things have tightened up since.
I am conscious that visiting not only puts my mum at risk, but all the other residents so have minimized my visits.
