Our verdict on One Mortgage System
One Mortgage System (OMS) is a cloud-based mortgage CRM and origination platform for UK mortgage intermediaries, lenders and building societies. Its broker CRM supports residential, buy-to-let, bridging, second charge, commercial and specialist lending. The platform combines case processing with mortgage, protection and criteria sourcing, encrypted document management, client and introducer portals, automated email and SMS updates, credit searches, property valuation estimates, reporting and management information dashboards. It is a strong fit for UK advisers that need one system spanning borrower management, referral partners, loan pipeline tracking and compliance workflows.
OMS follows a contact-sales pricing model, so buying involves a sales conversation rather than a published standard plan structure. The platform is available through web and API access. Its integration coverage includes Ignite, Submissions Brain, The Source, Twenty7Tec, iPipeline, Hometrack, Experian, Equifax, Uinsure, Air Sourcing and Knowledge Bank. Lenders and building societies also get API-led origination with customer and broker portals, underwriting workflows and task management. That makes OMS relevant where adviser workflows and lender-side processes need to connect within the same operating environment.
The standout strength is breadth across the mortgage case lifecycle. Customisable workflows, underwriting and task management sit alongside sourcing, document handling, communications, valuations and dashboards, while the Curvestone integration adds AI-assisted compliance case checking. This range suits firms that want structured case administration and compliance activity rather than a narrow contact database. Advisers seeking an integrated UK mortgage operation should consider OMS; teams wanting a lightweight CRM, self-service pricing or a narrowly focused tool may prefer a simpler alternative.
