Bring a friend along to exhibitions, events and the Members' Room by adding a Guest facility to your Membership card. With a guest facility you will receive a card which Admits two, and can bring a different guest of your choice each time you visit. You will need to accompany your guests, and your Membership card will be in your name and non-transferable. If you have a joint Membership and wish to add a guest facility this must be added to the primary cardholders’ Membership in the first instance. Please note that we are unable to change the primary cardholder during the Membership period and changes of this nature can only be made upon renewal. Secondary cardholders are able to add a guest facility once the primary Member has done so.
