The IOP has collaborative agreements with over 30 physical societies around the globe, a network which continues to expand.

Members of many of these partner societies are able to attend IOP meetings at reduced rates and have access to the members’ area at the Institute’s headquarters in London on the same terms as IOP members. In return, IOP members can attend meetings of partner societies at their members' rates. Other benefits such as access to Physics World and membership of the IOP are also available to some partner societies, depending on their mutual agreement with the IOP.

The IOP is a member of the European Physical Society, as well as the European Optical Society, and the International Commission for Optics. It has an active involvement in The International Union of Pure and Applied Physics, to which it is the adhering body for the UK and Ireland.
