The bank says its market share of gross mortgage lending has now grown from 8.75% in 2010 to 9.6% in 2011.
It says this growth is expected to continue with HSBC’s recent pledge to make at least £15bn available to UK homeowners with £3bn set aside specifically for first-time buyers.
This commitment would represent an estimated market share of over 11% and if delivered will provide deals for around 150,000 homeowners and over 27,000 first-time buyers.
It also advanced £11.9bn to SMEs last year, an increase of 15% compared to 2010.
The bank also reported a pretax profit of £1.5bn for its UK business in 2011, up from 17.2% the previous year.
Despite this the bank says it makes about 90% of its profits outside the UK.
Globally HSBC reported annual profit growth of 15% to £13.8bn.
Joe Garner, head of UK retail banking at HSBC, said: “Despite the ongoing challenging economic conditions, during 2011 HSBC used its unique international strength to lend record amounts to both UK businesses and individual customers and critically our net lending to businesses grew against a backdrop of a shrinking market.
“We remain fully committed to helping the UK economy continue to recover and we will continue to support our customers through the challenges ahead.”
