National Obesity Audit

Data Provision Notice to require the submission of data from providers of publicly funded weight management services, in relation to person-centred information for children and adults who are in contact with those services.


The Secretary of State has directed NHS England to analyse and link obesity data to support the NHS Long Term Plan, which aims to provide better outcomes for patients.

The aim of the National Obesity Audit is to measure weight management service provision, interventions and outcomes to support current and future services to deliver efficient, effective and equitable prevention and care. The NOA is a patient-level data set which will cover all aspects of weight management services that are publicly funded by the NHS and the Department of Health and Social Care (DHSC) in England. The NOA will follow the patient journey from primary to secondary care, looking at all areas of care, interventions and outcomes.


This Notice is served on:

  • general practices in England (via CVDPREVENT Audit)  
  • NHS or local authority funded specialist weight management services in England that deliver relevant care 
  • NHS trusts and independent hospitals that report to the Care Quality Commission (CQC) and provide NHS funded secondary care services in England that carry out obesity related bariatric surgery and interventions

Legal basis


The NOA uses existing data collections to collate the relevant data and is bound to existing submission timelines for each. Timelines for these can be found on the relevant webpages.
