Submit your KO41b before this Saturday’s deadline

The dental practice written complaints data collection (KO41b) is open.

If you’re a dental provider in England, you need to:

  • submit a KO41b for each contract you hold
  • submit data for complaints made by, or on behalf of, patients between 1 April 2020 and 31 March 2021
  • submit your KO41b before 11:59pm on Saturday 30 October 2021

Submit your KO41b online.

Why it’s important to submit your KO41b

It is a statutory and contractual requirement for primary care providers to declare brief details of complaints associated with their NHS care by submitting a KO41b return.


Guidance notes for completing the KO41b collection are available on NHS Digital's website.
