By taking part in our clinical trials you will earn from £100 per day. You’ll also receive £15 to £100 depending on where you live towards travel expenses when you come for your screening appointment and for all out-patient visits.


The payment you receive for helping us with our research varies from study to study depending on its complexity and duration. Payments are based on the number of times you might have to stay overnight in the clinic and how many outpatient visits you need to attend. If the study runs for a long time, e.g. over two months, that may also increase the study payment due to the longer period of important study restrictions, such as reduced exercise and alcohol intake.

A list of our current studies, and the payments they entail can be found on our study list.

How will I receive my payment?

We'll send you a cheque within 7-10 working days of your screening visit or last study appointment.

If the study runs for a long time you may be paid in installments.

How many paid medical trials can I do?

You can only take part in one paid clinical trial at a time, however you can participate in a maximum of three to four per twelve month period. Over 60% of our UK clinical research volunteers go on to take part in additional trials.

Declaring payments to HM Revenue & Customs

As a UK resident, it is your responsibility to declare any payments you receive for taking part in a clinical research study to HMRC. If requested by HMRC, Covance is legally obliged to provide a list of participants and the corresponding payments made for all paid clinical trials.
