Audit & accounting basis
- Accounting basis
- FRS 102
- Reporting scope
- Standalone (parent only)
- Auditor
- BDO LLP
- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“In auditing the financial statements, we have concluded that the Directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Charitable Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”
Significant events
- “The 2024-2025 financial year has been one of landmarks and milestones for UK Biobank. Perhaps the most significant step regards sharing of GP patient data for research.”
- “The first phase of our record-breaking Imaging Project crossed the finishing line. With more than one billion imaging scans...makes UK Biobank the world's largest whole-body imaging project, scanning the brains, hearts, abdomens, blood vessels, bones and joints of 100,000 volunteers.”
- “In January, we announced the launch of the world's most comprehensive study of circulating proteins, which will transform research into diseases and their treatments.”
- “2025 also saw a successful pilot of our new Brain Health Study. Funded by the Sergey Brin Family Foundation, it has the ambitious aim, over the next 10 years, to scan the brains of the many thousands of participants who will experience neurodegenerative conditions such as dementia and Parkinson's disease.”
- “During the year, construction of the new site progressed and remains on track for completion in mid-2026, with the building 'topping out' in May 2025.”
