Aspergers son to live independently while at university

Hi all,

My Aspie son aged 18 is going to be attending a London University in September, and is not able to stay in halls due to our central london Location. My husband is moving outside london for work and will not be able to commute, so we have spoken about the possibility of our son living independently , and getting him another aspergers maths/ science student to  live with him in a flat share.

Although our son is incredibly bright and mature, he currently has no social life other than attending school, and no real friends and it really concerns me that he spends so much time alone with his computer, so I hoped that by finding him another person with aspergers and similar interests to live with, he may be able to develop a long standing friendship with someone. However, I have absolutely no idea where I might find this other aspergers student attending a Central London university. It would be helpful if it was an older student studying maths too.
