Since its foundation in 1929, The Questors has had a reputation for achieving the highest standards of any amateur theatre in the world, both in the quality and the professionalism of its productions. With its own theatre complex (the Playhouse seats up to 400 people and the Studio caters for more intimate audiences of around 100), rehearsal space, workshop and professional technical facilities, it offers opportunities for excellence in all areas of theatre production and design.

As well as exploring the mainstream of modern and classical world drama, The Questors has always been respected for championing new or rarely performed plays, and for encouraging experimentation. The Company's artistic aims and objectives are outlined in The Quest.

The theatre complex in Mattock lane, Ealing has good public transport links and free parking adjacent to the theatre.
