Crawshaw, formerly group chief executive of Bradford & Bingley plc, succeeds Jon Pain in the role.
Mark Parsons, Barclays managing director of Home Finance, and Richard Brown, managing director Bank of Ireland Personal Lending, have been appointed as this year’s deputy chairmen.
Crawshaw said: “While the fallout from the credit crunch has been well documented, let’s not forget the strengths of the UK mortgage marketplace. The UK boasts a competitive and innovative mortgage market which currently helps over 11.8 million households.
“Looking ahead, 2008 will be an uncertain year for the mortgage industry and lenders will continue to respond to funding constraints. But it is entirely possible that the market will recover sooner than expected.
“One of the CML’s main challenges this year will be making sense of the aftermath of the 2007 events and ensuring policymakers and commentators are accurately informed on the market environment as it evolves.”
