Improving Access to Psychological Therapies (IAPT) data set reports

Improving Access to Psychological Therapies (IAPT) is an NHS programme in England that offers interventions approved by the National Institute for Health and Care Excellence (NICE) for treating people with depression or anxiety.

Following the recent one-off resubmission exercise covering v2.0 data, NHS Digital will be updating the affected publications to ensure that the most up-to-date and accurate IAPT data is available to all of our users.

This is advance notice that we will update publications covering the data reporting periods September 2020 to May 2021 inclusive. This update will now take place on Thursday 16 December 2021 (revised from 9 December 2021).

The existing data will be replaced as part of the update. If you would like to retain a copy of the existing data for comparative purposes, please download what you need prior to 16 December 2021.

The IAPT programme is supported by a regular return of data generated by providers of IAPT services in delivering those services to patients. These data are received by NHS Digital and released as statistical publications covering activity, waiting times and patient outcomes such as recovery. Further information can be found in the supporting documents section below.
