Family Fund UK. Can they help you?
From their website: Family Fund is the UK’s largest charity providing grants for families raising disabled or seriously ill children and young people
"Last year, we provided 89,101 grants or services worth over £33 million to families across the UK.
Our purpose is to improve the lives of low-income families raising disabled or seriously ill children and young people.
Our mission is to provide items and services to all low-income families in the UK raising disabled or seriously ill children, that they could not otherwise afford or access, and that help improve their quality of life, realise their rights, and remove some of the barriers they face.
Our vision is that all families raising disabled or seriously ill children have the same choices, quality of life, opportunities and aspirations as other families."
