ViewMyChain says the integration of its management tool into Property Data Trust’s framework has enabled it to tackle one of the most persistent sources of friction in the UK property market – the lack of shared visibility across transaction chains
The proptech firm says that for the first time, chain status can now be viewed and exchanged using an open, recognised standard.
This allows all parties involved in a transaction – estate agents, conveyancers, lenders and technology providers – to speak the same language when it comes to chain progression.
Greater transparency and data sharing significantly reduce fall-throughs and prevent delays.”

Maria Harris, Chair of The Open Property Data Association (OPDA), says: “This extension to the Property Data Trust Framework brings clarity where it was most lacking for consumers and industry – chains.
“Greater transparency and data sharing significantly reduce fall-throughs and prevent delays, all made possible when our members collaborate on data and common standards like we have with ViewMyChain.”
Unique Property Reference
This is achieved with the help of Unique Property Reference Numbers (UPRN) – a government-backed identifier for each property, ensuring data can be matched, tracked and interpreted consistently across different systems.

George Barnes, Lead Engineer at ViewMyChain, adds: “From the start, we wanted to make sure chain data didn’t just meet a standard – it had to be useful and deployable in the real world. This update brings structure to one of the messiest parts of UK property data, and it’s been built with production use in mind. We’re excited to see others adopt and build on it.”
