Admissions: how the two schools differ
Distance between the schools: 2.3 miles in a straight line between the two school sites. The coordinates come from the GIAS (DfE) March 2026 extract. This is not a walking or driving distance and it does not show which school your address is in catchment for.
How full they are: pupils on roll divided by published capacity from the GIAS (DfE) March 2026 extract. Both figures cover every year group (including any sixth form). Treat the percentage as a rough guide to demand rather than the size of the Year 7 intake.
