- Listings & Marketplaces (Discovery layer)
Where people find properties.
Examples
• Rightmove
• Zoopla
• OnTheMarket
Function:
• property listings
• search and alerts
• agent marketing
These platforms don’t provide deep property intelligence — they mainly provide listings.
⸻
- Data Infrastructure (Raw data layer)
This is where the underlying property datasets live.
Sources include:
• HM Land Registry
• Environment Agency
• Ofcom
• Companies House
Platforms and APIs aggregate this data into structured datasets.
For example, some platforms maintain tens of millions of UK property records and millions of daily data points for analytics and applications. 
⸻
- Professional Intelligence Tools
These are paid tools used by investors, lenders and developers.
Examples:
• PropertyData – investment analytics and deal analysis
• Sprift – dashboards with 300+ property data points across 30M homes 
• Nimbus Maps – development and planning intelligence
• LandInsight – land and planning data
This is the “Bloomberg Terminal for property professionals” layer.
⸻
- Consumer Property Intelligence (Where HouseData fits)
This is the emerging category.
Instead of tools for developers or banks, these platforms help buyers, homeowners and landlords understand a specific property instantly.
Key example
• HouseData
What it does:
• aggregates official datasets
• generates instant property reports
• explains property risks and history
Users can quickly access information like:
• EPC ratings
• flood risk
• price history
• planning activity
• broadband availability
—all pulled from official sources in seconds. 
The platform also includes an AI assistant (“Hilda”) that can interpret property documents and explain planning or title information.
