Scottish Building Society has begun rolling out Instamo’s FastSubmit Solution, providing selected intermediary firms with access to a one-click mortgage application submission process.
Instamo has confirmed that the mutual is adopting the technology to streamline how brokers submit mortgage applications, removing the need to manually key cases into lender portals.
FastSubmit is designed to map structured application data directly into lender-native systems, reducing friction in the submission process and saving time for both brokers and lenders.
Through the rollout, intermediary firms can submit cases using Instamo’s one-click submission journey, while Scottish Building Society continues to receive applications seamlessly within its existing lender workflows.
The solution works alongside current systems rather than replacing them, triggering all existing validations, rules and verification steps exactly as if an application had been entered manually.
FastSubmit is available to intermediary firms through a dynamic API that maps directly to existing CRM data structures, enabling one-click submissions using structured client data.
Alternatively, brokers can submit cases via a drag-and-drop PDF fact find, with FastSubmit extracting and mapping the required information automatically, without the need for any technical integration.
Instamo founder Freddie Savundra said: “We’re excited to be working with Scottish Building Society as they roll out FastSubmit with selected intermediary partners.
“FastSubmit works out of the box and integrates directly with their existing systems rather than replacing them, making it easier for firms to submit applications and support the Society’s growth plans, while giving brokers a much faster and simpler submission experience.”
Stephen Brown, head of intermediaries at Scottish Building Society, added: “Partnering with Instamo allows us to enhance the broker application journey while working seamlessly with our existing systems and processes.
“FastSubmit supports our ambition to simplify submissions, reduce friction, and continue delivering a high quality service to brokers and their clients.”
