Frozen The Musical was originally due to begin performances in October of this year but the ongoing theatre shutdown has seen the opening moved to April 2, 2021.
Disney said: "All existing bookings have automatically been moved into a new date... Ticketholders have received an announcement email, and will receive a new confirmation email with details of their booking as soon as possible - due to the volume of guests, this may take up to five weeks.
"If any guest is not happy with their new date, they will be able to request an alternative date, a Frozen voucher or a refund by following the instructions in their confirmation email. We ask all guests to whom this applies not to get in touch until after you receive your new confirmation email.
"Thank you for your patience and understanding, we look forward to sharing this magical story live on stage from April 2021."
Frozen The Musical is based on the hit 2013 animated movie of the same name.
The stage show features all the big songs from the film plus more than 10 new ones, all written by husband and wife team Kristen Anderson-Lopez and Robert Lopez.
The book comes from Jennifer Lee, who wrote the film's screenplay, while Michael Grandage directs with choreography from Rob Ashford.
