A process to replace him has begun and is expected to conclude towards the end of 2013. In the meantime Adrian will remain in post until a successor can be appointed
Commenting on the decision Mr Coles said: "I have enjoyed, and continue to enjoy, being the BSA's director-general, a position I hold with considerable pride. However, now is the right time for me to seek to develop my career in other ways.
“I have held this post for 20 years, and it is time for a change, both from my point of view and that of the Association.
“A new regulatory regime will be in place shortly and it is right that a new leader takes the BSA into this new age. Also, the mutual sector is recovering strongly after a difficult period in the financial and mortgage markets, giving my successor a very strong base from which to work.
“A strong membership, combined with the strong Secretariat that we have built up over the last few years, gives me plenty of confidence that the BSA is well placed to continue to play an influential role in the future."
Commenting on Adrian's contribution to the work of the BSA, David Webster, chairman of the Association (and chief executive of the Hanley Economic Building Society), said: "Adrian has been an outstanding ambassador for the mutual sector since joining the BSA as an economist in 1979, and he has played a pivotal role in guiding our industry through good times and tough times.
“He is hugely respected, not only in the UK but amongst financial services businesses overseas, for his perceptive grasp of economic, political and regulatory issues and his ability to distil such complex topics into meaningful and impactful priorities.
“Adrian has shaped the BSA into a robust, professional and respected organisation. He will be a tough act to follow and we wish him every success in his future career."
