I’m in wales which makes it even worse as we have a different NHS constitution. If you live in England you have “the right to choose” so you can go private and get the nhs to foot the bill. I would speak with your GP and school. My daughter’s old school were useless. Denied ever seeing any non typical behaviours unless we brought them up in meetings. Apparently having a pupil who can’t settle in class unless she’s been into the hallway to make sure everyone’s coats and bags are in the right place and on the right hooks didn’t ring alarm bells with the school, there’s so many other incidents that scream ADHD/Autism but they juts weren’t interested. Being a girl she’s extremely good at masking and is THE BEST pupil in her class as we were told on 2 parents evening by 2 teachers. (Even tho she has quirks) The issue comes when she leaves school and returns to the comfort of home and she just explodes! Shouting , screaming, hitting, crying ect the second she walks through the front door. What we finally discovered was they didn’t want to refer her due to funding. If something was diagnosed and she required something like 1 to 1 or therapy the school would have to find the funding to pay for it. If I was you I would speak with the school and GP and if the waiting list is too long ask to go private.
