National Property Transaction Network (NPTN) is an industry-wide initiative, led by LMS, with a bold mission: to digitise and modernise the UK property transaction ecosystem. By bringing together estate agents, lenders, brokers, law firms, and technology providers, NPTN aims to simplify the home buying and selling process through seamless, data-driven innovation.
At the core of NPTN is Horizontal Digital Integration (HDI) – a foundational principle that enables interoperability across stakeholders. By breaking down data silos and enabling joined-up digital processes, HDI supports a consistent, efficient experience across the property lifecycle.
NPTN is aligned with regulatory standards and is committed to building scalable, transparent, and sustainable solutions that drive trust and innovation throughout the property market.
The NPTN Sandbox: A Controlled Environment for Innovation
To bring transformation to life, the NPTN Sandbox offers a secure, structured, and non-live environment for testing and refining digital solutions. Operating in focused 6-week innovation cycles, each phase is designed to simulate real-world scenarios, capture actionable feedback, and validate new approaches before wider deployment.
This iterative model accelerates market readiness while prioritising inclusivity, stakeholder alignment, and resilience.
First Use Case: Digital ID Verification and QES
Launching in July 2025, the inaugural use case tackles one of the most friction-laden areas of property transactions: identity verification and deed execution.
Key Objectives:
- Enable a single, reusable digital ID verification across all parties involved in a transaction.
- Eliminate physical witnessing requirements by implementing Qualified Electronic Signatures (QES).
- Remove manual, postal workflows to reduce delays and improve efficiency.
Success Metrics Will Include:
- Acceptance of QES-enabled deeds by law firms, lenders, and HM Land Registry (HMLR).
- Measurable improvements in customer experience and transaction turnaround times.
Multi-Party Participation: Powering Real-World Innovation
This first cohort brings together a broad coalition of pioneering partners:
- Verify365, a leading digital identity and compliance technology product, is championing this first cohort and driving forward innovation in digital verification.
- OMS (One Mortgage System), the integrated broker application platform, is simulating broker workflows to ensure the solution works across the entire transaction journey – not just for legal and lending stakeholders.
This collaboration ensures that every part of the transaction chain is engaged, informed, and able to shape future-proof solutions from day one.
The Participating Lenders
A cohort of 15 lenders are contributing to transformation efforts via The Sandbox. The following lenders are among those contributing to the initiative:
- Gen H
- HSBC UK Bank Plc
- LiveMore
- Lloyds Banking Group
- Loughborough Building Society
- Melton Building Society
- Molo
- NatWest Group
- Newcastle Building Society
- Skipton Building Society
- TSB
Broader Sector Impact and Ecosystem Integration
The NPTN Sandbox is designed not just to improve operational outcomes for participants, but to catalyse industry-wide progress by:
- Fostering interoperability with other innovation initiatives.
- Informing policy through rich insights from live testing.
- Supporting national scalability of validated, digital-first solutions.
The Role of Smart Data
NPTN’s success hinges on the intelligent use of structured, reusable data:
- Verified ID can be safely reused across multiple touchpoints.
- Deed execution and related workflows can be automated securely.
- Uniform data standards increase trust and ensure regulatory compliance.
This approach underpins the vision for a smarter, more connected property transaction ecosystem.
Nick Chadbourne, CEO at LMS, states:
“The NPTN Sandbox is a step forward in our mission to modernise the UK property market. By focusing our first innovation cycle on digital ID verification and Qualified Electronic Signatures, we’re addressing some of the most persistent friction points in the transaction process. A single, reusable ID and QES-enabled deeds can eliminate paper-based delays, reduce fraud risk, and significantly speed up completion times. This isn’t just about digitisation, it’s about building trust, resilience, and interoperability across the sector.”
