I found a site a while ago which listed fees -it was around £50k for a full time course in London or Birmingham, or hundreds per hour for the consultant to deliver training and workshops which are frequent.
It’s completely beyond our means - I also found a FOI request stating that our council only funds ABA for one child in the whole borough at present. We have no hope of funding.
I’m doing what I can myself but it’s very frustrating not being able to afford to access these things while they are still so young.
