We investigate complaints about the NHS in England and UK government departments and their agencies.
Enquiries received are the number of concerns we saw about the NHS in England and UK government departments and their agencies. Many customers come to us seeking advice on where and how to complain and we provide them with that information. Where customers have completed the service provider's complaints process, the enquiry is taken on as a complaint to be assessed.
Assessments are the number of complaints we considered in further detail. At this stage we look at the length of time since the customer became aware of events and the availability of a legal remedy. We accept complaints for investigation if it appears there may be an outstanding injustice due to service failure or maladministration.
