Local social services are the responsibility of individual councils. Councils are required by law to have a social services complaints procedure.
If you are unhappy with the service you have received, you should contact the local council that provides the service. UK Online provides an A-Z list of local authorities.
The Health and Care Partnerships Directorate, which is part of the Department of Health, cannot investigate complaints from members of the public.
If your complaint is not resolved by the local complaints procedure, you can then complain to the Local Government Ombudsman. The Local Government Ombudsman system has been set up by the Government to monitor the actions of local government.
