FAQ
Frequently asked questions
What is Chimnie?
Chimnie brings UK property data together in reports, an API and bulk files. It provides 300+ attributes for any of 35M+ residential and commercial properties: construction, physical attributes, valuations, rebuild costs, flood and other perils, planning, EPC, geospatial and market data. Teams use it to assess property value, risk and characteristics.
Where is the data sourced from?
We connect hundreds of proprietary, private and public datasets, including HM Land Registry, Ordnance Survey, Royal Mail, ONS, BGS and Defra, and enrich them with AI modelling into a single Chimnie record per property.
Why use Chimnie instead of collecting the data myself?
You can obtain some of the underlying data directly. Chimnie brings public, private and proprietary datasets together. Our advanced address matching reconciles very different datasets to the same property before we remove duplicates and standardise the result. We then add modelled insights such as valuations and risk. Thousands of users on our consumer platform, chimnie.co.uk, also contribute to crowdsourced quality assurance: their feedback helps us identify discrepancies and refine the data, alongside feedback from API customers. Your team gets one usable property record through reports, API or bulk data, without building its own data pipeline. See how we turn sources into property insights
What is a property record?
Each Chimnie record holds all information associated with a single property at a specific address, keyed by UPRN. Data from every source is merged into that one record.
Do I need an account to try it?
No. The dashboard and the CH1 1MN sandbox addresses work without an account or API key and return synthetic test data. For real properties, create a free account and start with up to £16 of free balance.
How much does it cost?
Pay as you go from £0.05 per property, with request packs from 10,000 requests at 20% to 70% off, and flat-rate pricing for the full dataset. New accounts get up to £16 of free balance and there is no minimum commitment. See pricing
What fields are available?
The complete field list, with types and examples, is published in our API documentation. View the schema
Can I get the data as a file instead of an API?
Yes. Any subset of fields can be delivered as a flat file (CSV) for your whole portfolio or the full UK dataset, with optional monthly updates. Talk to us about flat files
