Property Deals Insight Joins the Open Property Data Association to Advance Digital Property Transparency

Property data platform Property Deals Insight has joined the Open Property Data Association (OPDA), marking a strategic step toward greater transparency, standardisation and accessibility in the UK property market. The association, founded to accelerate the digitisation of property data and streamline the homebuying process, brings together key stakeholders across the property ecosystem — including lenders, intermediaries, conveyancers and proptech firms — to develop open data standards and frameworks that make property information easier to find, understand and share.

Property Deals Insight aggregates more than 40 million property records from across the sector and presents them in a standardised format, enabling more efficient matching, analysis and decision-making for homebuyers, brokers, conveyancers and lenders. By joining OPDA, the platform will contribute to ongoing efforts to digitise property data and transform traditionally manual, fragmented processes into more transparent, data-driven experiences.

The OPDA’s work builds on the industry’s growing appetite for smarter data solutions that reduce friction in property transactions — a challenge highlighted in recent research showing widespread frustration with the homebuying journey and strong demand for digital transformation.

Key Highlights

• New OPDA member: Property Deals Insight joins the Open Property Data Association.
• Data aggregation: The platform standardises more than 40 million property records to support better decision-making.
• Industry impact: Membership supports OPDA’s mission to digitise and unify property information across the market.
• Improving transparency: Joining aims to help property professionals and consumers make faster, data-informed decisions.
• Ecosystem collaboration: Property Deals Insight becomes part of a growing network of OPDA members working on digital data standards.

What This Means for the Property Market

Tackling Fragmentation and Lack of Standardisation

For years, the property market — particularly in the UK — has operated with siloed and inconsistent data sources. This fragmentation makes it difficult for buyers, intermediaries and lenders to access reliable information early in the transaction process. Without clean, standardised data, property professionals face delays that often contribute to longer transaction times and higher costs.

Property Deals Insight pulls together millions of records from multiple datasets, standardising them into a single, searchable and interoperable format. This makes information easier to locate, compare and use — whether for property valuations, market analysis or due diligence.

By joining OPDA, the platform now participates in an industry-wide push to standardise property data for the benefit of all stakeholders.

Supporting Digital Homebuying and Faster Transactions

The Open Property Data Association’s initiatives — including its Property Data Trust Framework (PDTF) — offer open data standards that enable property information to be shared securely and efficiently. These standards aim to reduce transaction friction, speed up decision-making, and improve transparency at every stage of the homebuying process.

Research commissioned by OPDA and industry groups has highlighted how outdated processes — including manual searches, siloed systems, and fragmented data — contribute to lengthy transaction times and frustrated consumers. Standardised, digital data flows are seen as a critical way to overcome these challenges.

Becoming an OPDA member allows Property Deals Insight to integrate its data capabilities into this broader ecosystem, contributing to a more connected, compliant and customer-friendly property transaction environment.

The Role of OPDA and Broader Industry Adoption

Since its launch, the Open Property Data Association has rapidly grown its membership base to include a wide array of organisations spanning the property lifecycle — from mortgage lenders and brokers to conveyancers and proptech innovators. Notable members now include Mortgage Advice Bureau (MAB), NatWest Group, HSBC, Nationwide, Lloyds Banking Group, Atom Bank, PEXA and Coadjute.

These participants collaborate to build and adopt open property data standards, create interoperable digital platforms, and support tools that reduce redundancy and increase transparency. The OPDA’s work draws some inspiration from the Open Banking movement — wherein standardised APIs and shared data structures transformed financial services by enabling secure, interoperable data exchanges.

In recent months, OPDA has also been advancing its Property Data Trust Framework, with schema updates that enable clear visibility of milestones in the transaction process and facilitate consistent sharing of survey and valuation data across lenders, brokers and conveyancers — an important step toward a more seamless, data-driven property market.

Industry and Consumer Benefits

Greater Transparency

Integrating diverse property data into a shared standard reduces opacity in the homebuying process. Buyers, sellers and professionals gain quicker access to trusted information, helping them make informed decisions with more confidence.

Improved Efficiency

Digitised and interoperable data flows can reduce repetitive manual checks and lower the risk of errors. This efficiency not only speeds up transactions but also reduces costs for consumers and industry participants alike.

Enhanced Decision-Making

Mortgage brokers, lenders and estate agents benefit from richer datasets that are easier to compare and analyse, helping them serve customers more quickly and effectively.

Broad Support for Digital Transformation

The growth of OPDA membership — including innovative proptech firms like Property Deals Insight — signals a collective industry move toward smarter data practices and digital transformation that could reshape how property transactions are conducted in the next decade.
