Enable your research

UK Biobank is a uniquely powerful biomedical database to support your research. Our goal is to enable your vision for novel scientific discoveries that improve human health. We do this by providing easily accessible, de-identified data on half a million participants to scientists all over the world to undertake imaginative and pioneering studies that will transform health.

Discover UK Biobank 

UK Biobank is a world-leading biomedical database to enable scientific discoveries that improve human health. Our goal is to inspire the imaginations of health researchers around the world to meet the challenge of greater understanding, prevention, and treatment of a range of serious illnesses. UK Biobank has Research Tissue Bank Approval till 2026 and through access to an unmatched amount of de-identified biological and medical data on half a million people living in the UK, we can enable your vision of improving human health. 

  1. UK Biobank is a longitudinal study; it follows the health of 500,000 volunteer participants.
  2. Participants were aged between 40-69 years when they joined UK Biobank between 2006-2010.
  3. Each participant attended a baseline assessment at a centre in England (89%), Scotland (7%) and Wales (4%).
  4. Participants provided their consent for long-term follow-up.
  5. Participants answered lots of questions about their health & lifestyle.
  6. Participants donated samples of blood, urine and saliva for long-term storage and analysis.
  7. Physical measurements were also taken (e.g. height, weight, spirometry, blood pressure, heel bone density).
  8. Many participants have undertaken MR brain & heart imaging, activity monitoring and online follow-up questionnaires.
  9. We have genetic data on all 500,000 participants.
  10. UK Biobank is not representative of the general population with evidence of a ‘healthy volunteer’ selection bias, details of which are published online.

You can find a summary of all the information collected on participants so far in our Data Showcase.

Data Showcase

Imaging study

UK Biobank is conducting the world’s largest health imaging study for 100,000 participants, with 10,000 returning for repeat imaging 2 years after their first visit. The project includes MRI of brain, heart and body, full-body DEXA scan of the bones and joints, and an ultrasound scan of the carotid arteries. 

Imaging study data

Health records

On joining UK Biobank, participants consented to have their health followed over many years through linkage to their health-related records. UK Biobank has linked to cancer and death registry data, hospital inpatient admissions and primary care records. These data are generally updated annually. 

Researchers are helping UK Biobank to develop algorithms to identify common disorders such as stroke, heart disease and dementia. 

Health-related outcome data


UK Biobank has received funding from government, charity and industry to extract a range of genetic data from participant samples. 

  • Genotyping using Affymetrix microarray
  • Whole Exome Sequencing
  • Whole Genome Sequencing

Researcher requirements

Researchers must register with UK Biobank in order to use the data. To do this they must provide evidence that they are a bona fide researcher at an appropriate institute and submit an application detailing their proposed research for review by UK Biobank. Once approved and data have been released, researchers must: 

  • Notify UK Biobank of any research outputs resulting from the project at least 2 weeks in advance of their publication or release
  • Inform UK Biobank of any press releases associated with a UK Biobank project
  • Return the results of UK Biobank projects within 6 months of public release, including any derived variables and the code used to generate the results, so that they can be shared with other researchers
