This is a link to the fact sheets provided on adult social care by the Ombudsman.
The role of the Ombudsman for social care is to check if there has been any maladministration by Local Authorities and Care providers.
The site provides guidance on whether to make a complaint or not and how the Ombudsman may be able to investigate and help.
The Ombudsman rulings are binding on Local Authorities.
