For the Public

We’re working to improve health and care by helping researchers use data safely and responsibly. By securely linking information from long-term studies with NHS records, the UK CliC TRE supports discoveries that deepen our understanding of diseases and lead to better treatments and outcomes for people across the UK.

The UK Clinical Cohorts (UK CliC) Trusted Research Environment (TRE) is a secure system that helps researchers answer important questions about heart and circulatory diseases. It brings together information from long-term health studies and NHS records, so scientists can learn more about how these conditions develop, how they can be prevented, and how care can be improved for everyone. 

If you’re involved with one of the participating UK CliC cohorts, please read our Participant Notification Sheet.

Why does the UK CliC TRE matter?

Every year, millions of people in the UK are affected by heart attacks, strokes, and other circulatory problems. Researchers know a lot already, but there are still important gaps in our knowledge.

For example:

  • Why do some people respond better than others to certain treatments?
  • How do lifestyle factors like diet, exercise, and stress affect heart health over time?
  • Can we spot early warning signs that predict who might be at risk?

By safely combining different sources of health data, the UK CliC TRE gives researchers the tools they need to find answers.

How are people’s data kept safe?

Protecting privacy is at the heart of the UK CliC TRE.

  • Personal details are never shared – researchers do not see names, addresses, or anything that could directly identify you.
  • All research is carried out in a highly secure system run by Swansea University’s SAIL Databank, which is independently accredited.
  • Before any results leave the UK CliC TRE, they are carefully checked to ensure that no individual can be identified.
  • The system follows the internationally recognised Five Safes Framework: safe people, safe projects, safe settings, safe data, and safe outputs.

Who decides what research is allowed?

Not all projects are approved. Every application must show a clear public benefit and is reviewed by an independent panel called the Information Governance Review Panel (IGRP). Importantly, this panel includes members of the public as well as experts, so the public voice is always part of the decision-making.

What does this mean for you?

Thanks to the generosity of people who join health studies, researchers can make discoveries that improve lives, like:

  • Identifying who is most at risk of heart disease earlier, so they can get support sooner.
  • Testing which treatments work best for different groups of people.
  • Helping the NHS plan services more effectively, based on real-world data.

Your data is never sold, and it is only ever used for research in the public interest.
