Bath Building Society has partnered with fintech firm Sikoia to support the automation of mortgage document handling, income verification, and affordability checks using Sikoia’s AI-powered platform, working alongside Bath’s cloud-based mortgage origination technology provided by One Mortgage System (OMS).

By deploying Sikoia’s solution, Bath can reduce manual effort and turnaround times by automating key verification steps, enabling faster, more consistent decisions and an improved experience for brokers.

Through the partnership, Sikoia will provide Bath Building Society with a range of automated customer verification capabilities, including application validation and completeness checks and automated income and employment verification.

Documents are automatically validated at upload to ensure completeness, integrity, and policy compliance, providing instant feedback and reducing rework. 

Income and employment data is extracted and standardised from payslips and supporting documents, producing a clear income profile with automated risk indicators in seconds, to enable underwriters to make faster decisions.

In parallel, Sikoia’s services are available through OMS’s cloud-based lending origination platform, supporting a more streamlined application-to-completion journey for applications. 

Alexis Rog, founder and CEO of Sikoia, commented: “Automating verification is one of the most effective ways lenders can drive consistency and quality across the mortgage journey. By reducing manual document handling and automating income checks, Bath is strengthening decision-making and supporting a smooth, consistent experience for both brokers and customers. We’re pleased to be working closely with Bath to help optimise existing processes as they continue to modernise their technology stack.” 

Craig Brown, head of mortgages at Bath Building Society, added: “Automating document processing and verification will have a real impact on how quickly and consistently we can progress applications. By reducing manual checks and providing underwriters with the key information, summarised, we’re able to make decisions faster and give brokers clearer feedback, which ultimately improves the experience for customers.”
