UK Citizen abroad, living in South Africa, moving back. where to live?

Hello! Just signed up. I'm Tony.

I'm a 29 year old with Asperger's and PDA diagnosis. I am in the process of moving back to the UK from South Africa, hopefully by the end of March, provided I can pick a place to live. The criteria I'm following is that the area I choose needs to have some sort of Aspergers, and PDA support. I have selected 10 possible places to live, with the first 5 being the top choices at the moment. However, for a lot of them, my searches don't provide clarity on whether or not there are official, or even unofficial, support groups for Aspies/PDAers. 

So I was wondering if it would be okay to ask here if anyone has any idea of the overall support in the following cities for adults with PDA and Aspergers. The 10 places, are as follows:

1. Bristol
2. Cardiff
3. York
4. Harrogate
5. Farnham
---------------
6. Nottingham
7. Oxford
8. Cambridge
9. Guildford
10. Scarborough

also, if there are any suggestions about places that is okay to stay for PDA adults, or if any of the choices aren't considered ideal for those on the spectrum, by all means let me know. My uncle there is requiring an idea of where I want to end up after a brief period of staying with them in London, before aiding me in purchasing my air ticket.

I'll be grateful for any and all information.
