I have worked with an organization based in Guildford called Challengers (originally Disability Challengers) who offer play, interaction, one to one development work - and have all sorts of light and sound interaction rooms for their work with disabled children. Most of these are quite severely disabled and to give parents just a couple of hours a week break from having to look after their kids is a bonus. No child (or young person) is ever turned away for being too difficult.
Due to cutbacks they have lost some of their funding and have been really struggling to keep as many services going as possible. Our business has worked with them for 20 years helping with fundraising. The Guildford meeting agreed to give the £50 voucher to Challengers to use for whatever they needed and could get from Tesco.
