Data on written complaints in the NHS

The NHS complaints procedure is the statutorily based mechanism for dealing with complaints about NHS care and treatment and all NHS organisations in England are required to operate the procedure. The annual collection is a count of written complaints made by (or on behalf of) patients, received between 1 April and 31 March each year.

From 2015/16, the data is published quarterly. The quarterly data remain provisional and experimental and therefore subject to change.
