Choose Your Subscription Value

The BSBI is a charity and relies on voluntary donations to continue its work. If you can, we ask you to consider increasing the amount you give towards your membership. Any value you pay over and above the cost will be treated as a donation towards the work of the Society.

The Pay Now / Donate button below allows you to input the value you'd like and set your own payment for membership categories. Please use this button to pay any non-standard amount.

Gift Membership

All memberships are also available as Gift Memberships.

To take a subscription out in the name of a friend or family member, simply use the Paypal facility on this page to pay for their membership.

Then either email Gwynn Ellis with your friend's details and he'll send them a membership form to fill in or download the form and email it to your friend.

Once the form is received, the membership welcome pack will be sent directly to them.
