Phil Davies trained at the Royal Court Young Writers Programme where he developed his first script, Adjusted, which won the Rod Hall Memorial Award and gained him an attachment with Paines Plough. His debut full-length play, Firebird, premiered at Hampstead Downstairs, London, in 2015 in a production directed by Edward Hall.

Other work includes short play How To Not Murder (Arcola Theatre, dir. Ned Bennett); Up the Dale (Royal Exchange Theatre and Queen Elizabeth Hall for Paines Plough); Adjusted (Interplay Europe, Utrecht) and The Makings (ATG, dir. Sarah Dickinson).

He has worked alongside Synergy Theatre Project developing scripts with inmates at Feltham Young Offenders Institution, as well as teaching in a secondary school in South East London.
