Responses to this make me so sad. Essentially put up and shut up.
It could be discrimination under the equality act - you cannot refuse anyone entry because they are disabled, and where possible reasonable adjustments must be made to accommodate additional needs.
Most people point to the fact they will not have funding for a 1:1, therefore no reasonable adjustment can be made. That is not the end of this - why don't they have funding for this? I would challenge this with the local authority (I know others who have, and have been successful, and I plan to do the same if it becomes an issue when my disabled daughter starts school).
It does not make any kind of economic sense for you to not work 7 + hours a day, generating an income on which you will pay tax, and which will reduce the benefits you claim because you cannot access childcare for 2-3 hours a day.
Some people may question why the local authority should fund this when they don't contribute to neurotypical kids after school club fees. The answer would be because they is about equality for all, and that doesn't mean everyone getting the same. it is about levelling the playing field, not everyone gets exactly the same, because not everyone needs exactly the same. This "additional" funding would just enable that family to access exactly the same services as you already do - they are not getting more.
I would also question how many parents would so willingly and passively accept this situation if their child acquired a disability - as opposed to being born with one. I wonder if they would expect to give up their job, possibly their home, and their entire way of life because their child was no longer neurotypical enough to access after school childcare.
I often feel like when your child is born with a disability we as their parents should not expect equality, we must accept the cards that have been dealt and yes its unfair at times but also we can't expect those not affected to cough up to make society equally accessible for all. But often the same attitude does not prevail when a disability is acquired and it feels like something has been taken away or lost and suddenly it seems more unjust. This is a tangent but It's something I have noticed as a parent of a physically disabled child. If they have never been able to access a football club...that's ok, but if they used to be Part of a football team and then lost a leg, well they are part of the team and let's do all we can help keep them part of the team - amazing attitude, but wouldn't it be great to think like that when the kid born with one leg or in a wheelchair asks to join?
Appreciate this won't be everyone's experience but I do wonder how parents would feel if their child was asked to leave ASC because they acquired a disability.
I think people need to remember disability can happen to anyone at any time and this should be your fight too. I never thought it would be my life - but here I am, and I am shamed of how ignorant I was to the struggles before.
I'll stop my little rant there and brace myself.
Other options could be direct payments, if you have a disability social worker they should be able to carry our an assessment but you are not allowed to use them to over child care so you can work, it's more about respite or so they can access something which would benefit them which otherwise they couldn't, but you could maybe Argue ASC provides the childcare and direct payments is just used to make it accessible.
Alternatively a charity may help - you can apply for grants, although I appreciate relying on grants which may stop at some point isn't ideal for holding down a job.
I would also consider moving him to a specialist setting, one near us does offer after school care but appreciate not all do. It may benefit him anyway if he is spending 100% of the time out of the classroom.
But please do fight your LA for funding - I know one lady who managed to get it written into the EHCP. If you are on instagram her handle is alfieandlesley and she has some really helpful highlights on this.
Best of luck! I really hope you can figure it out.
