The firm said it outperformed the overall gross lending market by 22% in 2010.
The Council of Mortgage Lenders reported £142 billion in gross lending in 2009 falling to £136.3 billion last year.
Ben Thompson, managing director of Legal & General Mortgage Club, said: “Our objective is to deliver good value, quality and choice for our close business partners and members. We are successful because we have the ability to make the most of our strong corporate relationships with many banks and lenders but also we can continually research, analyse and measure real-time transactional data and trends to ensure we understand the needs of the market and react quickly to seize the right opportunities.
“Our strong relationships with many partners and lenders are vital and allow us to develop a broad choice of competitive products and services that have wide appeal.
“Despite the continued uncertainty in the housing market and with future regulation still a little unclear I am positive and optimistic for the year ahead. I believe that we will continue to grow in 2011, offering our loyal and supportive members even more value and choice”.
