What residential property data means
Residential property data covers all structured information about homes and dwellings — as distinct from commercial, industrial, or agricultural land. In the UK context this means data about the roughly 24 million residential addresses in England and Wales, from terraced houses to purpose-built flats.
The key characteristics that define residential property data are:
- →UPRN-matched — each property has a unique, stable identifier that persists across data sources and ownership changes.
- →Multi-dimensional — physical characteristics (size, type, age) layered with legal status (tenure, title), financial history (sold prices, valuation), and environmental context (risk scores).
- →Government-sourced — most authoritative residential property data originates from HMLR, MHCLG, and OS — Homedata normalises and delivers these via API.

Who uses residential property data
Residential property data underpins decisions across the entire UK housing ecosystem — from initial valuation to mortgage underwriting to conveyancing completion.
Estate agents
Residential property data powers agent valuation tools, market appraisal reports, and client-facing dashboards. Key data: comparable sold prices, EPC ratings, floor area, listing history, and days-on-market. Homedata's comparables engine ranks nearby sold properties by spatial proximity and property similarity.
Residential data for estate agents →Mortgage brokers and lenders
Lenders use residential property data for underwriting decisions: AVM valuations, EPC compliance checks (for green mortgage products), tenure verification, and flood risk assessment. Homedata returns all of these in a single enriched property record, reducing pre-offer processing time.
Residential data for mortgage brokers →Surveyors and valuers
Residential property data pre-populates survey reports: property type, floor area, construction age, EPC data, planning history, and environmental risk. Surveyors using Homedata reduce data-gathering time per instruction by 60–80%, spending more time on physical inspection and analysis.
Residential data for surveyors →Property investors and landlords
Residential property data supports portfolio analysis, deal sourcing, and rental yield calculation. Homedata's bulk download option lets investors pull large datasets filtered by property type, EPC rating, tenure, and geography — enabling data-driven acquisition strategies at scale.

What does residential property data include?
Residential property data includes all structured information about a dwelling: property type, number of bedrooms, floor area, tenure, construction age, council tax band, EPC rating, sold price history, estimated market value, environmental risk scores, and registered ownership. Homedata provides all of this for 29 million UK properties, matched by UPRN.
Does Homedata cover commercial property data?
Homedata focuses on residential property data. Many endpoints return data for commercial properties where it exists in underlying government datasets (EPC, ownership, planning, risk). Dedicated commercial market data — office yields, retail rents — is outside current scope.
What residential property data is available for free?
Homedata's free tier (no credit card) gives 100 API calls/month covering: address search, core property record, EPC rating, sold price history, flood risk, and broadband speed. Free tools — EPC checker, flood risk checker, postcode profile — require no signup at all.
How accurate is residential property valuation data?
Homedata's AVM estimates are trained on Land Registry sold prices and calibrated against property characteristics and comparable sales. In high-transaction postcodes, estimates typically fall within 5–8% of achieved sale price. Confidence scores accompany each estimate. AVMs are designed to support underwriting and portfolio monitoring — not to replace professional valuations.
Is residential property data UPRN-matched?
Yes. Every property in the Homedata database is identified by its UPRN (Unique Property Reference Number) — a stable identifier assigned by Ordnance Survey that persists across ownership changes and across all government datasets. UPRN matching lets you join Homedata data to Land Registry, EPC, or any other UPRN-keyed source without ambiguity.
