Membership is renewable annually and currently costs £5. If you come to the club just as your card is due to expire, you will pay an extra £5 on top of the normal members entrance fee, and your card will be renewed for you. If your card has expired (even if it is 2 or 3 years old!!) you can renew by just coming to the club, paying the members entrance fee plus a renewal fee (this depends on how old the card is - minimum £5, maximum £10) on top, and again, your card will be renewed. If you've lost your old card, you should still be able to renew, as your details should still be on the membership database - which will be searched on your arrival once you provide some details.
