In the new role, Pearce (pictured) is to be responsible for all propositions, development and management across the retail bank and wealth management products, including mortgages.
Greg Went is HSBC UK’s interim head of mortgages, with recruitment for a permanent head of mortgages expected to begin shortly.
Jackie Uhi is UK’s head of distribution for mortgages and wealth, while Chris Pearson remains head of intermediaries.
The changes come after HSBC recently introduced a new broker platform with increased functionality.
The site is designed to provide brokers with immediate Decisions In Principle, better document management and a single view of all pipeline cases.
The lender is placing more emphasis on the broker market this year, adding the number of broker partners it works with.
HSBC yesterday revealed it grew mortgage lending last year by around £6bn to hit £21bn. This is up from £15.7bn in 2016, according to UK Finance figures.
The lender added that its mortgage book had few defaults and impairment allowances, with the average loan to value (LTV) ratio on new lending of 59%.
This compares with an estimated 40% for the overall mortgage portfolio.
