Nearly 5000 RIBAmembers could save themselves £55 a year by stopping their registration with the ARB, former RIBA president David Rock told council. These people do not need to be ARB registered he said, because they are either retired (3013 of them) or based overseas (1692). 'We should be pointing this out to our members, 'Rock said, 'and saving them money.' This would not, he said, be purely altruistic on RIBA's part.'They would be less likely to leave the RIBA as ARB subscriptions rise.'
