Financial Support
- From 11+ entry, the School has a programme of Bursary support, to make entry to Westminster possible for promising pupils whose families are unable to afford the fees.
- We also award a number of Music Scholarships each year to recognise particularly gifted young people and some of these involve a part remission of fees.
