Santander has noted the positive contribution of both Bradford & Bingley (B&B) and Alliance & Leicester (A&L) to its Q3 profits.
Santander's UK banking arm, made up of Abbey, A&L, and B&B branches and deposits, made a profit of £1.16bn for the first nine months of the year.
Profit across the UK brands is up 58% compared to the same time last year. Loans grew by 43% and deposits increased by 46%.
Overall, profit for the first nine months at the Spanish banking giant was €6.74bn, 2.8% lower than in the same period in 2008.
Santander said the rise in its bad debt levels, up 0.21% from Q2, "was the lowest in five quarters." It also said its net profit for the three months to September came to €2.2bn.
Santander's results were in line with its own forecasts so it left its 2009 forecast for a profit of €8.8bn unchanged.
Chief executive Antonio Horta-Osorio says: "Our strategy of offering value-for-money products, underpinned by responsible lending and controlled costs, has seen us deliver a significant uplift in revenues and allowed us to continue to support the UK economy with increased lending to homeowners and businesses."
