Real Estate Platform Gains Market Leadership Through Data

The Client

A UK property data and analytics platform serving estate agents, property investors, and residential buyers. The platform sought to differentiate itself from established portals by providing deeper analytical insights rather than simply listing properties. Client identity withheld at their request.

The Challenge

The UK property market generates enormous volumes of data — asking prices, sold prices, rental yields, planning applications, EPC ratings, flood risk, and more — spread across dozens of sources with inconsistent formats and varying update frequencies. The client had a product vision but lacked the data infrastructure to realise it.

• Property data was fragmented across multiple public and commercial sources with no unified feed
• Inconsistent data formats, quality, and update frequencies made direct comparison unreliable
• Real-time market signals (new listings, price reductions, time on market) were unavailable via any single data provider
• Established competitors had years of historical data advantage
• The client needed a GDPR-compliant data strategy given that some property data can be linked to identifiable individuals

Our Solution

UK Data Services designed a multi-source property data aggregation and enrichment pipeline that brought together publicly available data, licensed feeds, and GDPR-compliant extraction from appropriate sources.

• HM Land Registry integration: Price Paid Data and registered titles ingested under the Open Government Licence — the legally cleanest property dataset in the UK
• Real-time listing monitoring: New listings, price changes, and withdrawn properties tracked across publicly available property data sources
• EPC and planning data: MHCLG Energy Performance Certificate data and local authority planning applications integrated to enrich each property record
• Data cleansing and deduplication: Address normalisation, duplicate record resolution, and quality scoring applied across all ingested data
• GDPR compliance layer: Personal data minimisation strategy, purpose limitation documentation, and retention schedules designed from the outset
• Analytics API: Clean, versioned API delivering market trend data, price indices, and property-level analytics to the client's front-end platform

The data strategy relied primarily on open government datasets and licensed feeds, with targeted extraction used only for publicly available asking price and listing data where no licensed alternative existed. All extraction was conducted within the bounds of applicable Terms of Service and UK law.
