The sessions are focused on giving brokers the tools they need to recruit, manage and progress their businesses.
A total of 39 self-employed brokers have already taken on new staff in recent months with the assistance of the programme, and the firm expects a further 15 by the end of the year.
Self-employed brokers can set up their own business under the umbrella of the Just Mortgages brand.
The training sessions are currently taking place via video conference and take six weeks to complete.
Rodney Sloan, head of training at Just Mortgages, said: “Many self-employed brokers are lone wolves.
“They are brilliant brokers who are great at communicating with clients, however they lack the experience of managing another broker.
“The set of skills required is slightly different, and our training programme is designed to give these brokers all the tools they need to succeed.
“Key to the success of these programmes is the buy in from the participants. We never push people to take part and those who enrol onto the courses have to commit fully.
“Those who have committed have shown promising signs already and we are really excited about the future of the programme.”
