Depends on your situation, and also the availability of properties in your area. I have seen people go on the list with very little medical need, (sometimes none) and no overcrowding etc, and get housed within 6 months. And I have also seen people struggling with mobility, and/or living with 4 kids in a 2 bed flat, waiting for 5 years with no luck.
So you may as well ask 'how long is a piece of string' I'm sorry to say. If you want further answers, you'll need to contact your local authority (or whoever holds the housing list in your town.)
Amazed to see at least 4 or 5 messages 'withdrawn at poster's request' and 'deleted by MN' on the first page! WTF have people been saying???
