To save time queuing at reception you can purchase tickets in advance of your visit (1).
Payment is via Paypal, but you can use almost all UK credit/debit cards if you don't have an account with them. After completing payment you will be sent a code via return email which you will be asked to show when you arrive at the museum.
(1) Please note that advance purchase of your tickets does NOT guarantee access to the museum at your preferred time. Visitor numbers are currently restricted to 15 at any one time and entry will be on a first-come, first served basis.
Alternatively you can book exclusive access to the museum for your group by clicking here.
