Shawbrook bases its business model on lending to consumers in sectors that are underserved by traditional high-street banks and operates in five divisions: commercial mortgages, asset finance, business credit, secured lending and consumer lending.
Richard Pyman, CEO of Shawbrook, said: “Our focus on specialist teams, working in carefully selected markets and with a human approach to decision-making to deliver excellent customer service, has enabled us to develop a clearly differentiated business with impressive returns.
“It has enabled us to build a diversified, well-collateralised and growing book, increasing customer loans by over £900m to £2.3bn in the year to 31 December 2014, while achieving an underlying profit before tax of £49.1m, all supported by a prudently structured retail deposit funding base.”
