Brymore has no particular religious affiliation. An assembly is held daily, however, attended by all boys and teaching staff. This normally takes the form of a talk or reading, a prayer and a hymn. Visiting speakers are also invited to conduct assemblies. Parents can withdraw their sons from collective worship if they so wish.

Two school services are held during the year, which all boys and parents attend, the Harvest Festival and Carol Service. These are held in Cannington Parish Church. In addition, a Leavers' Service is held, at the School, midway through the summer term, to celebrate all that the year 11 and year 12 pupils have experienced and achieved.
