Not sure where to post this and it's long and complicated so try and be as short as possible!
DP's paternal grandparents are both very old, in their 80/90's and live next door to his mum and dad.
Over the last few years his nan has started to deteriate mentally and his grandfather physically.
At the moment his grandfather can hardly walk and has had a couple of accidents due mainly to being in unsuitable accomodation, but his nan refuses to either move or change the way the house is to help him, sadly she also won't allow anyone in the house, so no-one can even go round to help.
DP's dad is in a bit of a state about it all, but they have a complex relationship anyway so he won't stand up to his mother, DP's mum had enough and called Social Services. SS said they would go round and assess the situation, which at times nan agrees with, but when they turn up she won't open the door. Numerous times DP's parents have tried to get the SS in to assess his grandfathe but to no avail.
Tpday grandfather has had another fall, and the family are extremely worried he is going to do himself an injury, he's late nineties and living in a victorian terraced house with bloody steep stairs, he needs help.
Is there anyway/anyone we can contact to get around nan's stubborness??
She just refuses to let anyone in and never leaves, so I would assume it would have to be forced entry.
Any advice would be much appreciated.
