How can I book event tickets?

If you would like to book tickets for or attend an event and you have not yet received your membership card, don’t worry! You just need to use the temporary membership number included in your confirmation email after purchase to book events online. Our staff will then be able to validate your membership status when you arrive on the night.

We strongly advise you to book your tickets in advance as some of our more popular events can sell out fast and we don’t want to disappoint.

Can someone attend an event using my membership card?

Ri Membership at all levels is non-transferable. Only the member named on the membership card will be able to receive the benefits of membership upon presentation of the card.

Please ensure you bring proof of your membership with you when attending events.

Can I bring a guest with me to events?

You are welcome to bring along a guest. If your guest is not an Ri Member they will need to purchase a standard ticket and concessions are available.

Can I enter the CHRISTMAS LECTURES ticket ballot?

Members at all levels are eligible to enter the ballot for the coveted CHRISTMAS LECTURES tickets. Details about the Lectures and how to apply for tickets are announced in the early autumn.

How does gift membership work?

Gift membership is a great way to support the Ri and provide a loved one or friend with a unique gift celebrating their interest in science and the world around us. You can buy membership for someone else online. When purchasing, you will be able to choose whether you want the gift to be sent to you or the recipient, as well as the start date of the membership. You will also receive an email with a gift certificate immediately after purchase.
