How we process public health data.

Transfer of Public Health functions to NHS England

On 1 October 2021, as part of the government’s strategy to transform the public health system in England, responsibility for a number of public health functions transferred from Public Health England (PHE) to NHS England. NHS England is now therefore the controller for personal data processed to support these functions under the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. Other than the change in Controller there was no changes to patients’ personal data to discharge these functions, how it is processed or the services received by patients as a result.
