Suffolk Building Society has partnered with Mortgage Broker Tools (MBT), making its full product range available to the platform’s growing network of mortgage intermediaries across the UK.
The partnership extends Suffolk’s footprint to almost every major intermediary sourcing system, enabling brokers to access its specialist offering through MBT’s widely used affordability research platform.
MBT recently surpassed 2.5 million affordability searches, doubling its user engagement in under two years.
Launched in 2019, MBT is designed to support mortgage brokers in sourcing suitable lending options by factoring in affordability, criteria, product rates and credit profiles. Suffolk Building Society’s inclusion is expected to be particularly beneficial for advisers dealing with more complex borrower scenarios, as the lender is known for its manual underwriting approach and appetite for specialist cases.
MOMENTUM

Charlotte Grimshaw, head of intermediaries at Suffolk Building Society, said the timing of the integration reflected MBT’s momentum and the society’s ongoing focus on expanding broker access.
“Mortgage Broker Tools has seen really impressive growth in recent months, so we’re particularly excited to be joining the platform. Broadening the reach of our niche, award-winning proposition to as many brokers as possible is always top of our agenda,” she said.
“Many brokers who use us will already have access to MBT either independently or via their firm/network/club, so ensuring that we’re present will help brokers see our proposition and feel confident in meeting their clients’ needs.
“It feels like the next step after building on the work we’ve already done with MBT, helping brokers disclose customer vulnerabilities to lenders.”

MBT chief executive Tanya Toumadj welcomed the society’s addition to the platform, highlighting the importance of lender diversity for brokers tackling non-standard cases.
“It’s fantastic to have Suffolk Building Society onboard. Our goal is to provide brokers and their borrowers with as many options as possible, and the addition of Suffolk Building Society to our lender panel is especially helpful for brokers working on cases that fall slightly outside of standard residential borrowing, including lending into retirement, joint borrower sole proprietor, holiday let, self-build and expat.”
