Companies House Property API — Corporate Ownership by UPRN
Identify company-owned properties across England and Wales. Pass a UPRN, address, or Companies House number to retrieve corporate title holders, company registration details, and linked Land Registry entries. Built for property investigators, PropTech platforms, and due diligence workflows.
What's in the API
Corporate title holders
Land Registry title records where the registered proprietor is a company — matched by name and Companies House registration number.
Company details
Company name, registration number, registered address, SIC code, incorporation date, and current status from Companies House.
Portfolio lookup
Pass a company number to retrieve all properties registered in that company's name — useful for mapping landlord and investor portfolios.
UPRN-keyed
All results include UPRN where matched — join to EPC, flood risk, planning, and valuation data in a single pipeline.

What share of UK properties are company-owned?
Around 3–4% of residential properties in England and Wales are registered in a company name. Commercial and investment property has much higher corporate ownership rates.
Does the API include overseas companies?
Yes — overseas entity registrations at Companies House are included. The Land Registry's overseas entities register (introduced 2023) is matched where a company number is available.
How current is the data?
Land Registry title data is updated monthly. Companies House data is updated daily from the Companies House API. Matching is re-run on each update cycle.
