Why take part?

 A token of our appreciation

Participants will receive a £15 gift card for providing a 24-hour urine sample, as a token of our appreciation.

 A little time to make a big difference

It’s easy to say no to our interviewers, but we hope you don’t. We’re not asking for money, just that you spare some time to take part and contribute to important policy making.

We know your time is precious, but our work really does make a difference. We help government and charities to make the right decisions about the big issues.
