The first launch under new head Phil Whitehouse, the union is designed to help TMA position itself as a 'one-stop-shop' for brokers.
Loanmakers deals with business from both prime and non-conforming clients, with TMA highlighting its marketing support services and quality of commission terms.
The loans firm also never goes direct, meaning that all systems and people processes are geared towards looking after intermediary business.
“It is important to choose the right partner when looking to add to any service proposition and after careful consideration Loanmakers was the best fit for TMA in terms of its offering and being the right fit for our members," said Whitehouse, adding that similar partnerships were planned for the coming months.
He continued: "Loanmakers' innovative IT system alongside dedicated staff, knowledge and expertise will be of great benefit and provide a new dimension to our member offering."
