The system is designed to save time and reduce re-keying errors for brokers, and integrates with any advice software and lender portal.
It means advisers at Quilter will now be able to access all TSB mortgage products and apply for them through their existing systems.
Mortgage applications are pre-populated with data already captured in advice and sourcing software.
Iress executive general manager, product, Andrew Simon (pictured), said: “It’s always been our goal to bring the industry together and Lender Connect has the potential to do that.
“Never before have lenders, distributors and intermediaries been able to interact seamlessly regardless of the platforms they are running.
“In bringing on board both sides of the value equation, we’re a huge step closer to achieving this goal.”
TSB mortgage distribution director Roland McCormack added: “TSB is committed to the intermediary market, and our pilot launch with Iress Lender Connect is a huge step forward in streamlining the end-to-end process for our broker partners.
“This is just the start of our journey to deliver two-way connectivity, and we’re thrilled to be partnering with Iress and Quilter to transform the mortgage application process.”
