The national data opt-out was introduced on 25 May 2018, enabling patients to opt out from the use of their data for research or planning purposes, in line with the recommendations of the national data guardian in her Review of data security, consent and opt-outs.

Patients can view or change their national data opt-out choice at any time by using the online service at www.nhs.uk/your-nhs-data-matters or by calling 0300 3035678.

By 30 September 2021 all health and care organisations are required to be compliant with the national data opt-out policy.
