Vernon Building Society has announced a partnership with FintechOS to support its investment in a unified mortgage platform that covers the full lending lifecycle.

The platform covers the complete origination workflow, from initial enquiry and decision in principle through to application, underwriting, offer, completion and further advances, running across the society’s existing core infrastructure without requiring system replacement.

Powered by FintechOS 8, the solution provides The Vernon’s end-to-end mortgage origination with decision workflows, built-in compliance rules, and the ability for the society’s teams to design and launch new mortgage propositions using no-code configuration and AI-enabled capabilities.

This approach is designed to help the lender respond more quickly to member needs and changing market conditions, while reducing reliance on complex technical change.

Furthermore, the platform unifies product and pricing governance with origination execution. The Vernon can configure and evolve business rules, eligibility criteria and offer construction logic within a governed layer above the core, with versioning and auditability to support consistent outcomes and adviser workflows.

The update comes as building societies provided 32% of all UK net mortgage lending in H1 2025, with total mortgage balances totalling £493bn.

The Vernon said it chose to partner with FintechOS as part of a major investment to modernise its mortgage lending capabilities and improve the experience for members, brokers and colleagues without the disruption of a full system replacement.

Chief executive officer (CEO) at Vernon Building Society, Darren Ditchburn, said: "This is an important step forward for the Vernon. Our partnership with FintechOS gives us a modern, flexible mortgage platform that will significantly improve the experience for our members, brokers and colleagues.

"It allows us to combine the stability of our core banking systems with the innovation needed to support future growth. Most importantly, it helps ensure we continue to provide great service, quicker human decision making and a more transparent mortgage journey, while remaining true to our mutual purpose."

CEO and founder at FintechOS, Teo Blidarus, added: “The real cost of legacy technology isn’t only what it takes to maintain, it’s the opportunity cost: products you can’t launch, policy changes you can’t implement quickly, and experiences you can’t deliver.

"Forward-thinking building societies like the Vernon are choosing a pragmatic modernisation path: modernise above the core, unify product and pricing logic with origination execution, and move faster without the risk and disruption of full system replacement. Their leadership recognises that the institutions willing to move first will shape the next era of UK lending, and we're proud to be the platform powering that ambition."
