What property data does Homedata provide for surveyors?

The Surveyor Package gives you EPC ratings (current + potential), flood risk, radon, noise, landfill proximity, coal mining, air quality and invasive plants risk, council tax bands, comparable sales, property records (type, age, floor area, bedrooms), and solar assessments. All via a single REST API with transparent call-weighted pricing — most property data endpoints cost 1 call, address find costs 2, retrieve costs 5.

How much does the surveyor API package cost?

The Surveyor Package maps to Growth (£149/month for 10,000 calls). A typical RICS Level 2 report needs 5-7 API calls — that's 1,400-2,000 reports per month. Free tier available with 100 calls/month for testing. No contracts, cancel anytime.

Can I pre-populate RICS survey reports with this API?

Yes. Address lookup returns the UPRN, then 5-7 calls populate: property type and construction (property record), EPC data (current and potential efficiency ratings, floor area, construction age band), flood risk, radon and other environmental risks (one call per risk type), council tax band, and comparable sales for the valuation section.

Does the API include environmental and flood risk data?

Yes. The Risk & Environment module covers 7 risk types: flood, radon, noise, landfill, coal mining, air quality, and invasive plants. Each is a separate call — GET /api/risks/{risk_type}/?uprn= — and returns a risk level (Very Low to High) with source attribution and a plain-English description.

What's in the Surveyor Package

Core Property + Risk & Environment + Market & Pricing modules. Everything a surveyor needs for RICS-compliant reports — without logging into 6 different websites.

Core Property · 1 call

Property record

Property type, construction age, bedrooms, bathrooms, floor area, garden, parking, and full transaction history. The foundation of every survey report.

GET /api/properties/{uprn}/

Core Property · 1 call

EPC energy data

Current and potential energy efficiency ratings, EPC floor area, construction age band, and certificate reference. Direct from the EPC register.

GET /api/epc-checker/{uprn}/

Risk & Environment · 1 call

Flood risk assessment

Flood risk — river flooding and surface water — with a risk level from Very Low to High. Source-attributed and suitable for RICS Level 2 and 3 reports.

GET /api/risks/flood/?uprn={uprn}

Risk & Environment · 1 call each (most endpoints)

Environmental hazards

Radon, noise, landfill proximity, coal mining history, air quality, and invasive plants — six more risk types beyond flood. One call per type, each returning a risk band with source and description.

GET /api/risks/{radon|noise|landfill|coal_mining|air_quality_today|invasive_plants}/?uprn=

Core Property · 1 call

Council tax band

Band and billing authority for any UK property. Takes postcode + building number — pre-populate the council tax section of your report without manual VOA lookups.

GET /api/council_tax_band/?postcode=&building_number=

Market & Pricing · 2 calls

Comparable sales

PostGIS 0.5-mile radius search. Up to 200 comps sorted by bedroom match and proximity. The evidence base for your valuation section.

GET /api/comparables/{uprn}/

Doing solar or energy surveys? Add the Solar Assessment endpoint.

The solar assessment endpoint returns panel count, kWp capacity, annual generation, savings (with and without battery), payback period, and CO₂ offset — all from a UPRN. One call to populate a complete solar feasibility section.

Address → UPRN → property record + EPC + flood risk + environmental + comps. Automate the data-gathering stage so surveyors spend time surveying, not Googling.
