London Theatre Seat Filling
Enjoy complimentary and discounted access to West End musicals, plays, opera and fringe theatre across London — as a discreet My Box Office seat filler.
Join todayLondon is one of the theatre capitals of the world, with the West End hosting world-class productions every night. Yet many shows have unsold seats — and that's where My Box Office members come in.
As a seat filler, you help venues create a full house while enjoying complimentary or heavily discounted access to theatre productions across the city. Members pay just a small admin fee (typically £1–£5) per booking. All we ask is discretion — never discuss the price or My Box Office at the venue.

Discretion is Our Golden Rule
Because our members receive tickets for a fraction of the face value, it's vital not to discuss the price or My Box Office at the venue. This protects the experience for full-price-paying patrons and ensures producers continue offering these exclusive opportunities to our club.
