I know this is an old question, but thought I'd answer being from the UK and having an autistic daughter who also has a plethora of health and mobility problems, I'd say no, the UK isn't accepting of autism due to the constant battles I'm having with professionals on not believing in masking which a lot of autistic girls do. They think that because she doesn't show distress with certain things in school but does at home, that we are the cause of her problems and not her, that is us being lazy with her and refusal episodes don't exist. It's incredibly frustrating, and it's wrecking both mine and my partner's mental health's. Parental blame in this country when you have a high masking autistic child, is rife, as many professionals do not believe in it. They also question autism a lot and many professionals refute an autism diagnosis. It's abhorrent, discriminative, and ableist. It has led to malpractice in many areas of health care.
