The awards, which recognise product and service providers across a range of personal finance disciplines, are voted on by consumers.
Andrew Bloom, managing director, said: “Masthaven Secured Loans has been established for just over three and a half years.
“So it is highly satisfying to win such a prestigious award voted for by consumers.
“Having been successful in winning awards for our work through the adviser channel, this vote of confidence from the people who actually use our products and service is a tremendous boost.”
He added: “I am also delighted on behalf of the Masthaven team, who provide the great service and human face behind our product range.
“We have built a strong proposition backed by our people, who make it their business to provide the kind of service to customers that this award recognises.”
