About the Our Future Health research programme

We’re bringing together data from up to 5 million adults in the UK. Registered researchers can request access to this data and analyse it to discover new ways to prevent, detect and treat diseases.

The aims of the programme

The programme aims to provide 2 main resources for health research:

  • an observational data set for basic science, epidemiological discovery and aetiological research
  • a cohort of participants who can be contacted for translational research

Our research resources

Registered researchers at Our Future Health can:

  • request access to our baseline health questionnaire, our genotype array data, NHS England linked health records, participant geographies, and our clinic measurements data. In the future, we will make more data types available. Learn more about our data types.
  • apply to access the highly secure Our Future Health Trusted Research Environment (TRE) to conduct analysis and collaborate with your colleagues
  • use the wide range of data analysis tools available in the TRE

"I've worked with large data sets before, but nothing that's quite the same scale as Our Future Health. The wealth of health-related data available will ensure that people from historically under-represented groups are not only included in the research but also benefit from its results in the years to come."
