About us


UK Biobank is a large-scale biomedical database and research resource, containing in-depth, de-identified genetic and health information from half a million UK participants. The database, which is regularly augmented with additional data, is globally accessible to approved researchers and scientists undertaking vital research into the most common and life-threatening diseases. UK Biobank’s research resource is a major contributor to the advancement of modern medicine and treatment and has enabled several scientific discoveries that improve human health.

Since 2006, UK Biobank has collected an unprecedented amount of biological and medical data on half a million people, aged between 40 and 69 years old and living in the UK, as part of a large-scale prospective study. With their consent they regularly provide blood, urine and saliva samples, as well as detailed information about their lifestyle which is then linked to their health-related records to provide a deeper understanding of how individuals experience diseases.

UK Biobank data is used by approved researchers from all types of academic, charity, government and commercial organisations for health-related research that is in the public interest.

UK Biobank has achieved these ambitions through the support of its visionary funders, the Wellcome TrustMedical Research CouncilDepartment of HealthScottish Government, and the Northwest Regional Development Agency. The organisation has over 200 dedicated members of staff, based in multiple locations across the UK.

What we do

UK Biobank is the most detailed, long-term prospective health research study in the world, enabling the international scientific community to better understand a range of common and life-threatening diseases. We continue to maintain this focus through the adoption of pioneering technologies and regular health follow-up on half a million participants. Our actions support the vision of the health research community to improve the future health of millions of people.


The UK Biobank study includes 500,000 participants, recruited between 2006 and 2010.

Prospective studies need to be this large because only a small proportion of the participants will develop any one condition over time and the effects of different exposures on the development of that condition are likely to be small.


When the Medical Research Council and Wellcome Trust established UK Biobank, they pioneered a new approach of undertaking public health research. Since then, we have continued to be at the cutting edge of population-based research by taking advantage of new scalable technologies, whether that be performing genomic analysis, and collecting accelerometer and multi-modal imaging data.


By creating the most in-depth health resource in the world, we are transforming opportunities for health research.  Through the commitment of half a million participants, we continue to expand our collection of biomedical data with comprehensive follow-up and precise assessments to address the challenge of understanding a wide range of life-threatening diseases. 

Future proofing valuable data

Since inception, UK Biobank has adopted pioneering technology to support its world-leading biomedical resource. For example, collecting and storing samples from half a million participants (into 10 million separate tubes) required an innovative solution and led to advances in the field to develop the UK Biobank automated freezer. 

The ability to transform the biological samples into data that can be used by researchers (such as genomic data, and data on circulating levels of hormones, metabolites and proteins) is crucial to advance our understanding of disease.  As technologies advance, we are able to extract the biological samples to perform measurements that are at the cutting-edge of life sciences.

UK Biobank is up there with our greatest achievements from the last 25 years...

and perhaps more than any other, UK Biobank will continue to be talked about in 100 years. People watched UK Biobank and are now replicating it in other parts of the world, and that is testament to its strengths, its governance and its impact. It’s not just what Biobank does, it’s the influence UK Biobank has on everything else.

Sir Jeremy Farrar, Director, Wellcome
