Challenge
Melton Building Society (MBS) manages a range of specialised and diverse mortgage products, such as self-build, impaired credit, buy-to-let, and shared ownership. With these intricate lending needs, it became critical for MBS to adopt a modern, flexible system capable of handling their unique requirements. However, their existing manual processes and rigid systems created multiple roadblocks:
- Friction in the borrower journey, slowing down the lending process
- Inability to integrate with key APIs, limiting efficiency and access to modern tools
- Outdated technology, with no capacity for real-time adjustments or improvements
- Slow operational processes, leading to delays in critical decision-making
Dan Atkinson, Head of Distribution at MBS, explained, “We needed an origination portal capable of managing the complexities of specialist lending while also enhancing the user experience and streamlining decision-making. Our previous system simply lacked the flexibility and control we required.”

Mast’s platform empowered MBS to control many aspects of their lending rules, making adjustments in real time without needing extensive coding.
