Re: British Aikido Board membership fees question
As Darren has covered, there is an annual association fee based on the number of insurance certs issued in the previous year. You then pay £1.40 for all certs issued. In addition, instructors pay £52 approx for instructor indemnity insurance.
If your association is not already a member of the BAB, I believe that you have to have 100 members or more to apply, and are given some sort of probationary period before your organisation is accepted as a full member.
