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 (September 2025) includes imputed genotype data on 159,587,100 variants and 550,000 participants

These data were obtained using a custom Illumina Infinium Excalibur beadchip array, designed by Our Future Health in collaboration with Illumina. The array includes variants related to a wide range of health phenotypes, blood typing, pharmacogenetics, selected copy number variants, clinically relevant variants, and a “backbone” of variants to support imputation.

A separate, linked dataset is available that provides participant baseline demographic information and responses to our baseline health questionnaire. Clinical measurements data is also available from participants. Additionally linked NHS England data that provides clinical information on participants is also available.

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.
