The two divisions will have their own managing directors, who will liaise with the Spicerhaart estate agency chains.
The two managing directors have been promoted from within Just Mortgages.
Tommy Taylor will become the managing director for the eastern division and Duncan Jones for the western division.
Both Taylor and Jones were previously Just Mortgages’ financial services directors.
This growth has come as the business expanded the services that it provides, beyond mortgages and protection to also encompass equity release and wealth management.
The firm now intends to double its number of employed mortgage and protection advisers from 125 to 250 and aims to increase its wealth business tenfold over the next year to £30m of business.
John Phillips, national operations director of Just Mortgages and Spicerhaart, said: “The team has pulled together in both good times and bad to achieve a truly phenomenal level of growth over the past few years.
“We have continually grown both the number of clients and the level and frequency of service we provide each client.
“We have done this at the same time as expanding the services that we provide them.
“Our aim is to grow by providing a truly holistic financial advice service, looking after every part of a client’s financial needs.”
Jones added: “This is a huge opportunity for the growth of Just Mortgages and everyone within it.
“The new structure will enable Tommy and I to really focus on the growth of our divisions and the company as a whole.
“As we have grown, we have not only seen an increase in the number of clients, but also a huge rise in the number of mortgage advisers who want to join Just Mortgages.
“This new structure enables us to take on more advisers while also providing them with the high level of training, mentoring and career progression that Just Mortgages is renowned for.”
Taylor said: “This is more than just a restructure, it positions Just Mortgages, and all who work within it, for the next stage of growth; a growth that will take us from being a mortgage and protection business to a true financial services business.
“At the same time we can offer progression opportunities for mortgage advisers at all levels, from those just starting in the industry, to those who want to progress their careers into a different type of advice, or even become self-employed.”
