Find and join research
that matches you

Find approved research that matches your health and needs, and help push research forward.
Get access to specialised knowledge, potential treatments, and research that is otherwise hard to find.

Health research, with you.

Today, 80% of all research projects in the UK are delayed or cancelled entirely because researchers cannot find the right participants. Every time this happens, important knowledge is lost. You can help change that. When you take part in health research in the UK, you directly help research create new knowledge that can lead to better treatments for future generations. When you participate, there are also often personal benefits to being involved:

Compensation for your participation.

Access to unique examinations and treatments.

Access to specialised knowledge and research.

Help drive progress in research.

Research is nothing without participants

"I took part in a research project at Københavns Universitet and it was a really great experience. I always felt safe and the researchers were kind and welcoming. I would strongly recommend taking part in research projects — you contribute to new knowledge too."

Jens, 57 years old

"Taking part in a research project was new to me, and I wanted to do my small part towards something big, important, and beneficial for many, including myself. Taking part was exciting and educational — exercising was tough and required a certain amount of endurance and determination, but the researchers were great at supporting, pushing, and motivating me to keep going. Completing it was very satisfying. Both in terms of contributing to the project, mentally, and the physical wellbeing the exercise gave me. All in all, it has been wonderful to be part of it."

Susanne, 63 years old

"I am part of a project that isn't finished yet, but so far it has been nothing but positive. Everyone involved is incredibly kind and patient, and comes across as very professional and competent. I am very pleased. It's great to be able to contribute to science. I also chose to participate for selfish reasons — it has also helped me get started with exercise."

Carina, 57 years old
