An Audit Commission review found that in some areas groups such as care leavers, teenage parents and domestic abuse victims and their families were still not receiving a good level of support.
It found that some local authority children's services were not involved in commissioning decisions surrounding specialist housing support.
Safeguarding of children was also questionable in some areas, with concerns remaining over a lack of checks on landlords and other residents when young people are placed in bed and breakfast accommodation.
The report added: "Arrangements for safeguarding have improved, but inspections have identified particular areas of concern, for example where young people are placed in bed and breakfast accommodation. Evidence from inspections identified concerns over a lack of formal safeguarding protocols between some housing related support providers and some local authorities."
Despite these concerns the initiative was found to be effective in most areas in offering support to vulnerable groups. The review urges struggling councils to seek advice from better performing local authorities.
