Zing Mortgages, which was established in 2010, was also listed as a finalist in both the Best Service-based Business and Fastest Growing categories.
The firm prides itself on ensuring that advisers have the maximum amount of time to spend with clients, while compliance and administration is dealt with by a separate team.
Paul Flavin, who owns Zing Mortgages, said the award had come “as a complete shock”.
He added: “Breaking down the entire mortgage process has allowed us to ensure the right people are completing the right task at the right time. Advisers concentrate on providing the clients with great up-front advice while the administration team ensure that the mortgage application is processed smoothly and efficiently, keeping everyone in the process informed at all times.
“This really is a result of analysing the mortgage business to the minutest degree then building processes around each stage. From that point on you need a great team to ensure everything falls into place.”
