TwinsUK Registration

Thank you for your interest in TwinsUK. Our health research could not happen without our incredible volunteers.

Please be aware that we can only register twin pairs to TwinsUK. If you have previously registered with us in the past, please refrain from registering again and kindly email us instead at twinsuk@kcl.ac.uk.

In order to make sure we link the correct two individuals in a twin pair, one of you must register first and this will generate a unique registration link for the other twin. Please speak with your twin and agree who will register first and who will register second.

If you are registering first, start the registration process HERE.
