Theatregoers aged 26 and under will be able to get free tickets to roughly 20 shows a year at Harrow Arts Centre.
The public performing arts venue in Uxbridge Road, Harrow Weald, is one of 31 across the capital taking part in a pilot scheme to encourage younger audiences to take an interest in drama.
Harrow Council's arts and events service will receive £10,000 to subsidise an estimated 1,100 seats from February 2009 for two years.
Harrow Arts Centre hosts 75 events a year, of which roughly 20 would be eligible for the free ticket giveaway. That said, the grant from Arts Council England may encourage more bookings of theatre productions geared towards children, teenagers and young adults that are otherwise shirked because they prove financially unviable to stage.
Councillor Chris Mote (Conservative), portfolio holder for community and cultural services, said: "The funding will enable us to increase the numbers of young people attending events, particularly those aged 16-26 whom we know are under-represented in our current audiences. The funding will also allow us to put on works specifically tailored at specific at a younger audience.
"A key part of the work we will be doing will be to listen to what young people have to say about the kind of events they would like to see at Harrow Arts Centre.
"Word of mouth attracts young people, so events showcasing the talents of other young people as performers will continue to form part of the diverse range of shows we offer."
Moira Sinclair, executive director of Arts Council England, said: "This is a wonderful opportunity to showcase the wealth of talent that we have here in the capital, in much loved local venues as well as our national theatres.
"Traditionally attendance at arts events drops between the ages of 18-26, so we hope that this scheme will introduce more young people to the thought-provoking, physically exciting and visually entertaining world of contemporary theatre and in doing so create a life long love for the art form."
Tricycle Theatre in Kilburn High Road, Kilburn, is part of a 12-strong consortium of West End venues that won a special £300,000 grant to provide theatre entry to the under-26s at no cost.
