This is typical throughout the country; overcrowded, unsuitable, un-habitable properties belonging to local authorities or housing associations.
It's very difficult to deal with this due to severe shortage of properties. But deal with you must- but not by yourself.
There may be much at stake- if you are a secure tenant, then it's worth holding onto this house and push for repairs. If you have a standard assured shorthold, then moving, with local authority's help with regards to deposit, to a private sector might be an option.
