This week, we’ve added new volunteer data into our resource. Health researchers can now study information from almost 1.8 million people.

We release new data into our trusted research environment (TRE) every three months. A TRE is a secure computing environment in which registered researchers can conduct approved studies. The data is the health information that volunteers share when they join our programme.

So far, over 2.4m people have consented to join our programme. That number rises every day.

In the latest data release, the number of completed health and lifestyle questionnaires in the TRE increased by over 200,000. The total now stands at 1,781,891 people.

New data totals

Here is a snapshot of the types of data in our TRE, and the number of volunteers for each category, as of 10 June 2025:

Data type	Number of volunteers in the TRE
Health and lifestyle questionnaire	1,781,891
Genetic data	650,979
Clinic measurements	1,324,884
Linked health records	1,527,712

We began adding data to the TRE in January 2023. In the graph at the top of this page, you can see how our resource for researchers has grown over time.

Our volunteer group – at a glance

Our Future Health is the world’s largest health research programme of its kind. But size isn’t everything.

Our goal is to build a volunteer group that truly reflects the UK population. That way, we can help health researchers to identify differences in how diseases begin and progress in people from different backgrounds.

As things stand, we’re proud to say that our TRE contains health information from the largest ever number of participants from under-represented groups in a health research programme.

You can see a breakdown of our volunteer group by age, sex, ethnicity and household income below.

Next data release

The next data release is planned for September 2025. We will publish an update of the new figures just after that date.

Live studies in our TRE

Our volunteers’ data is already being used by health researchers to find new ways to prevent, detect and treat diseases.

In the following articles, you can read interviews with some of those researchers, to learn more about their work and how our volunteer group is helping.

• Professor Krishnan Bhaskaran: ‘The insights we get from Our Future Health will help cancer survivors live healthier lives’
• Professor Cathryn Lewis: ‘Our Future Health is a goldmine for studies on depression’
• Professor Jennifer Quint: ‘Our Future Health’s data will move the needle for lung disease researchers like me’
