Our Future Health is a prospective, observational cohort study of the general adult population of the United Kingdom (UK). The programme aims to support a wide range of observational health research. We gather personal, health and lifestyle information from each participant through a self-completed baseline health questionnaire and at an in-person clinic visit. We will further link this data to other health-related data sets. Participants have also given consent for us to recontact them, for example to invite them to take part in further or repeat data collections, or other embedded studies such as clinical trials.

The Our Future Health programme is currently open to all adults (18 years and older) living in the UK. In July 2022, we started recruiting participants in England and will continue to expand across the rest of the UK. The data we’ve gathered so far (May 2026) includes linked NHS England clinical data on 1,666,336 participants

Additionally, there are also a number of linked datasets available including: • Participant data, which contains information on participant sex, gender, ethnicity, month and year of birth, consent version, month and year of consent, month and year of registration, blood sample • Self-reported baseline questionnaire data, which contains information of socio-economic, lifestyle and individual and family health • Clinic measurements data, which includes blood pressure, height, weight, BMI, heart rate and POCT lipid profile • Genetic data, which includes both genotyping array and imputed genetic data in two file formats (pVCF and BGEN format), and files with sample QC, kinship, ancestry and PCA loadings information • Participant geographies data for all devolved nations including small area statistical zones such as LSOA, MSOA and Intermediate Zones

The data is stored in the Our Future Health Trusted Research Environment. We de-identify all participant data we gather before it’s available for use. All researchers will need to become registered researchers at Our Future Health and have an approved research study before they're given access to the data.

We aim to collect a variety of data types from up to 5 million adult participants from across the UK. We hope to make more data types available on a quarterly basis.
