Slater was born in Reigate, England into a musical family. His father Christopher Slater, a professional conductor and organist, was a professor at Royal College of Music in London. Slater started playing the Cello and Piano at the age of 5. His early musical gifts earned him a scholarship as a chorister in Christ Church Cathedral, Oxford. Slater got another scholarship this time to one of the oldest schools in the UK, Oakham School. After Oakham School Slater studied composition at London College of Music and techniques for composing for film at the Ealing Studios (1998). Slater studied with Nick Ingman and Rodney Newton.
