The Westminster Society provides contact between members through:
- The Westminsterian annual magazine
- electronic newsletters
- an annual reunion at the Harcourt Hill Campus.
Some regional groups also provide contact and reunion opportunities. It also links Westminster College alumni with the Oxford Brookes Alumni office and the wider university.
It is organised by an executive committee chaired by Peter Relf. There are around 800 members and the annual membership fee is £10.
