I dont think anyone newly released from prison will get social or council housing.
The waiting lists are far too long and they would be a low priority in terms of need.
The will if lucky get some sort of accommodation in a hostel / homeless support service. (At one time, and verified prisoners being released were advised to get a tent!)
This is why as mentioned up thread the talk of the Government having to book hotel rooms - all because they wanted to flex their political muscle and send a message leaving probation services, housing departments and the prisoners themselves without anythin in place to deal with the crisis caused by Labour wanting to virtue signal.
And as a poster upthread said, many councils now, because of lack of central government funding, no longer have staffed hostels.
Instead they use what are called unregulated housing. Basically this could be house owned by and individual who converts the rooms in to bedrooms and then lets the to the council. So you could have someon who is a drug addict or dealer, and young person with no family support, a woman escaping sexual exploitation and women escaping sexual abuse being together.
And although the law has now been changed to say councils cant use them for young people, it still means vulnerable young adults and others are alone in an unsupervised mixed housing situation.
They had a name like rotating door or something, where police would regularly drop of vulnerable young women to her "accommodation" only for a few minutes later a pimp or pusher turn up to take her out for reasons none of us would like to happen to any woman.
