What developers are building
PropTech startup: Enriching property listings with EPC ratings and flood risk scores — replaced a £2,000/mo Loqate contract.
Portfolio analytics platform: Bulk UPRN lookups to value and monitor 15,000+ properties in real time.
Insurance underwriter: Environmental risk scoring at the property level — flood, radon, coal mining, and landfill proximity.
Conveyancing firm: Address autocomplete with enriched property data — one API replaces three separate services.
Built on a real conveyancing platform. Not a data reseller.
Most property data APIs batch-import from Land Registry weeks after a sale completes. We know about completions the moment they happen — because Homemove processes them.
Live completion events
Transaction data updates from Homemove's conveyancing network before Land Registry batch uploads. Weeks fresher than competitors.
UPRN-precise by default
Every record anchored to a Unique Property Reference Number. Address-matched from OS AddressBase, not geocoded approximations.
One API. Not three.
EPC data, risk scores, and price history in a single call. No stitching together Loqate, the EPC register, and a flood risk provider.
Self-serve. No sales calls.
Sign up, get a key, make a call. Competitors like Loqate require a demo, a contract, and a procurement process. We don't.

Built for every property workflow
Whether you're a solo developer or a team at a regulated firm, the same API handles it
Valuers & Surveyors
Comparable sales, price history, and floor area data to underpin AVM models and desktop appraisals. UPRN precision eliminates address ambiguity in valuations.
PropTech & Mortgage Platforms
Address autocomplete that returns full property records — EPC, bedrooms, floor area, tenure — auto-populating forms without manual data entry. One API replaces three separate providers.
Insurers & Risk Analysts
Property-level environmental risk scoring — flood, radon, coal mining, landfill, noise, air quality, invasive plants — for underwriting and pricing models. Standardised scores, not raw GIS data.
Portfolio Managers & Investors
Bulk UPRN lookups to monitor, value, and analyse thousands of properties. EPC compliance gaps, price trends, and market data across an entire portfolio in a single batch run.
Estate Agents & Conveyancers
Instant property details at point of instruction — no more manual lookups. Pull EPC certificates, sold price history, and risk flags automatically from address or UPRN.
Developers & Data Scientists
Consistent JSON, versioned endpoints, an interactive playground, and a free tier. Build your side project or proof-of-concept without a sales call, a contract, or a credit card.
