The CML says: “The data show that, although lending remains heavily concentrated in the hands of the six largest lenders (an overall pattern that has been reinforced by the credit crunch), the next tier of medium-sized lenders increased their market share last year.
“The six largest lenders advanced mortgages worth £113.8 billion in 2011, compared to £110.8 billion in the preceding year.
“However, despite increasing their amount of lending in absolute terms, their share of the total advanced showed a modest decline in 2011 (from 81.9% in 2010 to 80.7% last year).”
