RGS Prep is the preparatory school of the RGS.
It is well known for its excellent academic and pastoral strengths alongside outstanding music departments and strong sport and extra-curricular opportunities for all boys. It has occupied the same site in a quiet, leafy residential area of Guildford since 1930.
In 1978 when the Royal Grammar School became independent, Lanesborough was also purchased by the same Governing Body. Lanesborough officially merged with RGS Guildford to become RGS Prep in 2021. The Head is a member of the Incorporated Association of Preparatory Schools; RGS Prep is also the choir school for Guildford Cathedral.
The three original late nineteenth century houses which the school occupies have been updated and greatly extended with new buildings to provide extensive facilities for the boys. They still provide a homely atmosphere for classrooms and form an attractive backdrop to the large playing field.
