LMS has expanded the National Property Transaction Network (NPTN) as 42 new stakeholders join the initiative.

The pilot launched in late 2024 and the next wave of adoption represents a milestone in building a digital ecosystem – one that is open, scalable, and focused on authenticated, reusable data.

LMS also has support from the Property Data Trust Framework and the Open Property Data Association.

The NPTN Sandbox, launched in July 2025, offers a safe, synthetic environment for testing real-world scenarios.

The first use case focuses on digital ID and QES-enabled deeds, with full collaboration across 15 lenders, tech suppliers, and legal partners.

LMS chief executive Nick Chadbourne says: “The stakeholders adopting NPTN aren’t just participating – they’re proactively shaping the future of property transactions. Their early adoption has been critical in helping us prove what’s possible when smart data flows securely and seamlessly between platforms, without restrictions or silos.”

“We’re incredibly grateful to every partner who has joined us at this stage. By working together with shared goals and transparent standards, we’re building an ecosystem that benefits everyone – faster processes, better data, and ultimately a simpler experience for the customer.”

The new stakeholders include: 

Tech suppliers: 

4Corners Property, 4Stamp, Acre Software, Actionstep, Addland, Alto Software Group, Armalytix, CLSQ, Collaborative Conveyancing, Credas Gazeal, InTouch, Legalito, Mortgage Brain, Moverly, Movemnt, One Mortgage System, Open Moove, ProConvey, SDLT Compass, Skenario Labs, Snappily, Sprift, Thirdfort, TM Group, Verify365 and Yoti.
