Louise Drewett is a British composer based in London.

Louise has had long-term collaborations with poet Clare Shaw, writing works for voices and choirs, and with theatre company Arbonauts, writing for productions at Inside Out Dorset and Latitude festivals.

In 2017 Louise became co-director of Sing Healthy, a charity running community choirs in Berkshire, for whom she has written and arranged many pieces. Louise’s community opera, Daylighting, commissioned for the Royal Academy of Music's 200th Anniversary, was premiered in 2022, along with a 10’ work for the London Symphony Orchestra, commissioned through their Panufnik Scheme.

Louise studied with Philip Cashian on a scholarship at the Royal Academy of Music, where she was Manson Fellow in 2021-2022, and was awarded the 2018 and 2019 Charles Lucas Composition Prizes. Her study was supported by the Charles Lucas Memorial fund, a Countess of Munster Musical Trust Award and a Vaughan Williams Bursary from the RVW Trust.
