Its 2009 annual results show that it has increased its gross lending share of the mortgage market from 13.9% in 2008 to 18.6% in 2009.
Net lending for the UK businesses, which also includes Alliance & Leicester, rose to £7.6bn in 2009 compared to £6.1bn in 2008.
The proportion of arrears by three months or more was 1.37% compared to the industry average of 2.4% in September 2009. Repossessions fell from 969 in 2008 to 820 last year.
The average LTV of the book is 52% for existing stock and 64% for new business. Santander said that mortgages drove the UK business performance in the second half of the year which it attributed to a reduction in fraud.
Overall the Santander Group posted a profit of €8.9bn (£7.8bn), up 1% from 2008 figures.
António Horta-Osório, chief executive of Santander UK, said: “Our full year results demonstrate clearly our business model and strategy are delivering superior results, allowing us to increase profits and revenues, balanced against controlled costs and prudent lending. This has enabled Santander UK to write significant new business and continue to support the UK economy with increased lending to home owners and businesses.”
