  • Retained Board Adviser to a mid-tier UK bank
  • an adviser to an overseas investment bank financing new start mortgage lenders.

He was the architect of Yorkshire Building Society’s Corporate Strategy in 1995 to remain as a mutual and not to follow the market trend of building societies converting to banks.

He led the development of Yorkshire Building Society’s distribution strategy for the new Millennium – integrating branches, telephony and the internet through the existing brand – and challenging the convention at that time for launching newly branded internet businesses.

Martin was the architect of the UK’s regulatory strategy to create greater diversity in banking, leading to numerous fintech banks entering the market and the growth of challenger banks.

He was a member of the leadership team that defined and implemented the UK’s post financial crisis banking regulatory regime that now underpins the work of the Prudential Regulation Authority within the Bank of England.
