I've raised £30000 to I would like to help a single mum with 2 children to get a little flat for them as they are living together with their nana in a small room

I would like to help a single mum with 2 children, a little boy 4 years old and an 11 year old girl. She is hard working but as a single mum it is very difficult to keep up with all the bills especially where most of them are going for medicine for her children. The girl has an immune deficiency and she has been hospitalised most of her life several times per year. They often did not have food to eat, living in horrible conditions. Currently they are living a single room not bigger than 20 square meters, 4 of them, including their grandmother. I would love to help them to get only a small flat, nothing special. Just a little one with heating and clean. If this will be acheived, then I will be as transparent as I can showing where all the money have gone!
