Cotality has joined the Open Property Data Association (OPDA) as the industry group continues its work to develop common standards for sharing property information.
The property data, software and workflow provider holds a database of more than 150 million property records, covering more than 25 years of historical transactional data.
It also monitors around 30.9 million UK residential properties each day for events affecting value and risk, drawing on more than 100 data sources.
Cotality provides analytics, AI and workflow tools to estate agents, lenders, surveyors and conveyancers, including valuation and surveying software used in nearly all UK property valuation instructions.
The company said joining OPDA was aligned with its plans to develop interoperable data sharing and increase digital connectivity across the property transaction process.
Its existing technology includes the Integrated Lender Hub, which connects lenders and surveyors and digitises parts of the valuation workflow.
Mark Blackwell (pictured), chief operating officer at Cotality, said: “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.”
OPDA’s membership includes banks, building societies, conveyancers, estate agents, technology providers and other property professionals working on the adoption of open property data standards.
Maria Harris, chair of the OPDA, added: “We’re delighted to welcome Cotality to the OPDA. As one of the sector’s most established data and analytics providers, they bring deep technical expertise and proven integration across lenders and valuation networks.
“Their involvement will be invaluable as we continue to build open, trusted standards to create a faster, more connected home buying and selling process.”
Since its launch, OPDA has developed open property data standards and models intended to make property information reusable and shareable across the industry, with the aim of reducing friction and improving transparency during transactions.
