LMS Expands NPTN with 42 New Stakeholders

Momentum builds as tech suppliers and law firms unite behind data-led interoperability.

LMS, the UK’s leading provider of conveyancing services, today announces the next phase in the evolution of National Property Transaction Network (NPTN), as more than 40 additional stakeholders join the initiative to shape the future of property transactions.

Following the successful pilot launch in late 2024, which demonstrated measurable benefits in speed, certainty, and efficiency across the home buying and selling process, NPTN has gained significant industry traction. This next wave of adoption represents a major milestone in building a truly interoperable, digital ecosystem – one that is open, scalable, and focused on authenticated, reusable data.

A Powerful Collaboration of 42 Stakeholders.

Why Smart Data Matters
The NPTN framework is built around secure, reusable, authenticated data. With support from the Property Data Trust Framework (PDTF) and the Open Property Data Association (OPDA), LMS and its partners are enabling:

• Horizontal Digital Integration (HDI) across systems and stakeholders.
• Reduced duplication, fewer touchpoints, and less friction.
• Faster time to exchange and reduced cancellations, as demonstrated in pilot outcomes.
• An inclusive network – open to any stakeholder (law firm, lender, estate agent, broker, supplier).

Innovation in The Sandbox
The NPTN Sandbox, launched in July 2025, is already in motion. It offers a safe, synthetic environment for testing real-world scenarios – accelerating progress without disrupting live systems. The first use case focuses on digital ID and QES-enabled deeds, with full collaboration across 15 lenders, tech suppliers, and legal partners.

Nick Chadbourne, CEO at LMS adds:
‘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.’
LMS welcomes additional organisations – law firms, tech platforms, lenders, brokers and estate agents – to join NPTN as we build toward a digitally connected future.
