For just £22 you can upgrade your Individual Membership to a Joint Membership so that one family member or friend can visit the Museum with you or on their own. The additional person must live at the same address. You will both receive a Membership card and can visit the Museumís exhibitions, Members' events and Members' Room independently. You will only receive one copy of the British Museum Magazine, Whatís on guide and enewsletter per household. Please note you can only Upgrade an Individual Membership, not a Joint Membership. For a Joint Membership, one or both Members may add a Guest facility to their cards (£25 per Guest facility).
