Some of the more recent developments under economist Edward B. Halse and historian Gus Lock have been the most financially ambitious in the school’s history:

• e-mail became the normal method of communication between staff, and all boys gained internet access
• a second edition of the history of the school was published (G. N. Frykman and E. J. Hadley)
• the school co-founded the Independent State School Partnership scheme
• sixth-form girls from King’s High School joined the CCF and some joint teaching started
• The Cheshire Science Centre was built on the site of the 1879 sanatorium
• the 1957 science block was demolished and replaced with the Thornton Building, containing the Mathematics, Classics and Religion and Philosophy departments
• floodlit games pitches became available
• the 1^st XV won the Daily Mail Cup, and national recognition was won by the school’s concert band and drama students
• all teaching in the original 1879 classrooms finished and a museum and functions room was opened.
• A project to bring King's High School onto the same campus as Warwick School was revealed in 2017. The move happened in 2019, just before the COVID-19 pandemic.
