The BOA is the managing body for Underwater Hockey in the UK. Corporate and personal memberships are a requirement of booking the pool. Once you start playing with us regularly (~4 times) you must become a member of the BOA.
Go to https://www.gbuwh.co.uk/register and specify LUWHC as your club and make the required payment (~£30 in 2024). The club officers (James, Alan, Graeme) will be told when your application is approved. All subsequent renewals will be made by the club in October of each year and the club will collect the appropriate fee from you at that time.
