Heathers is produced by Bill Kenwright and Paul Taylor-Mills. It will return to the Theatre Royal Haymarket for a strictly limited season from 28 June (previews from 21 June) to 11 September 2021.
In parallel to the show's return to the West End, the musical will also embark on its first tour of the UK and Ireland, in a separate production, opening at Leeds Grand Theatre on 28 July 2021.
