If you have applied for are or are likely to apply for Twickenham international tickets in the future please view the following help pages from the RFU. This includes a video showing how to use the Stadium App once you are allocated tickets.
a. Tickets will still be applied for in the same way via the club by emailing sandalrugbyrufc@gmail.com once the application window is opened (April for Autumn Internationals and August for the following years 6 Nations).
b. All tickets will be delivered to you via the Stadium App.
c. Tickets will still be allocated by the club but in this case the purchaser will have 48 hours to pay the RFU direct for these, after this the tickets will return to the RFU for resale and could be lost from the club allocation.. It is important that the tickets are paid for within this 48 hour period.
All future Twickenham tickets from the 2022 6 Nations competition will be issued in this way.
