OPDA Boosts Property Data Standards as Cotality Joins Digital Transformation Mission

Cotality has joined the Open Property Data Association (OPDA), signaling a major step toward standardising the UK’s fragmented property data landscape. For fintech professionals, this move by a primary data provider to adopt open standards addresses the persistent friction in mortgage lending and conveyancing, potentially accelerating digital transformation across the entire property transaction chain.

What was announced

Cotality, a provider of property data and workflow software, has officially become a member of the OPDA. The partnership is designed to support the association's goal of modernising the home buying and selling process through the implementation of open data standards. Cotality brings a significant data asset to the association, maintaining a database of more than 150 million property records that include over 25 years of historical transactional information. The company currently monitors approximately 30.9 million UK residential properties every day for events that impact both valuation and risk.

The integration of Cotality into the OPDA framework involves the use of its analytics, AI, and workflow tools, which are already utilised by estate agents, lenders, surveyors, and conveyancers. Notably, Cotality’s valuation and surveying software is currently employed in nearly all UK property valuation instructions. One of its core products, the Integrated Lender Hub, is already functioning to connect and digitise workflows between lenders and surveyors. By joining the association, Cotality aims to align its existing digital connectivity with broader industry standards for interoperable data sharing. This move places Cotality alongside a network of members that includes major High Street banks, building societies, and technology providers all working toward a more transparent property market.

"At Cotality, our mission is to make the UK property industry faster, smarter, and more people-centric. Through our integrated platforms – including our Lender Hub – we are already helping lenders and surveyors connect digitally, removing friction across the transaction chain. OPDA’s mission aligns directly with our strategic direction. We deliver significant parts of this data and digital connectivity on the ground today. Joining the association is a natural stepping stone, sharing our experience to help shape the framework needed to make home buying and selling faster, more reliable, and transparent for everyone."

Mark Blackwell, Chief Operating Officer at Cotality.

The companies involved

Cotality is a property data, software, and workflow provider that operates as an integrated partner to the UK property market. The firm specialises in large-scale data analytics and AI-driven tools that support the entire property transaction chain, from initial valuation to final conveyancing. Its reach is extensive, with its software playing a role in the vast majority of UK property valuation instructions, making it a foundational player in the mortgage and surveying sectors.

The Open Property Data Association (OPDA) is an industry body dedicated to the creation and adoption of open property data standards. It works to develop reusable and shareable data models that reduce friction and improve transparency in the housing market. The association operates within a wider regulatory and industry ecosystem that includes the Department of Business & Trade Smart Data Council, the Ministry of Housing, Communities and Local Government, and the Digital Property Market Steering Group. By fostering collaboration between technology providers, lenders, and estate agents, the OPDA seeks to establish a digital-first framework for the UK property sector.

What FF News has reported before

The momentum behind open property data has been building throughout 2026. In September, FF News reported that iamproperty Joins Open Property Data Association to Drive Open Data Standards in UK Housing, highlighting the growing list of technology firms backing the OPDA's mission. This drive for efficiency is a response to severe market friction; earlier in August, UK Homebuyer Uncertainty Surges as 95% Face Unexpected Costs, PEXA Research Reveals, illustrating the high stakes for consumers in a non-standardised market. Cotality itself has a history of deep-dive data analysis, as seen in the Cotality Report: 2.5M U.S. Properties Face $1.4TN Wildfire Risk as Conflagration Blind Spots Emerge, which demonstrated the company's capability in assessing complex property risks on a global scale.

What this means

The UK property market has long been a graveyard for digital efficiency due to siloed data and manual processes. Cotality’s decision to join the OPDA is a significant market signal because of the sheer volume of data they control. When a company that facilitates nearly all UK valuation instructions commits to open standards, it puts immense pressure on legacy lenders and conveyancers who have resisted interoperability. The industry is moving toward a "data-first" rather than "document-first" model. The critical question now is whether the rest of the valuation and legal supply chain can modernise fast enough to keep pace with these emerging standards, or if they will become bottlenecks in an otherwise digitising ecosystem.
