Changelog.
New features, data updates, and API changes from the Propalt team.
MCP Server launched
The Propalt MCP Server is now in public beta. Connect Claude Code, Cursor, Windsurf, or any MCP-compatible client to UK property data using natural-language queries. 12 tools shipped at launch, authenticated with your existing API key. See the MCP setup guide for configuration instructions.
EPC fabric data endpoints
Two new endpoints expose full EPC fabric data including wall construction, roof type, heating system, estimated fuel costs, and improvement recommendations for all assessed UK properties. Critical for AVM features that account for energy efficiency.
Landlord portfolio intelligence
The /audience-landlords endpoint now returns estimated portfolio size and aggregate portfolio value alongside individual property records — ideal for identifying high-value landlord prospects. Backwards compatible with previous responses.
UK House Price Index data added
UK House Price Index data is now available via the /hpi endpoint at local authority and regional geography levels. Returns monthly index values with up to 10 years of history.
Monthly and quarterly market data
Two new market analytics endpoints provide listings volume, sales volume, median prices, and SSTC timescales for any UK postcode area. Built on combined Land Registry, EPC, and listings data.
UPRN resolution latency
Fixed a regression where UPRN-to-property resolution would intermittently take >1s. Now consistently <100ms p99 for the common case.
OpenAPI 3.1 schema
The OpenAPI spec is now compliant with the 3.1 standard, including discriminator support across enrichment unions. Generated SDKs now produce properly typed responses for every endpoint.
