I'm browsing the BACP website, the directory for counselling and talking therapists. But most have many issues listed in their "What I can help with" section in their pages. I'm thinking its a jack of all trades, master of none sort of thing. The last two I met didn't seem to have much experience with something as nuanced as ASD/aspergers, nor the individual and intractable problems that come with it. Up to 50-60 quid for 50-60 minutes can add up too, and it often leaves me wondering if I have chosen poorly.
Without ratings or testimony, it's always a roll of the dice especially when it's expensive.
