Frequently asked
How much of Harley Street is owned by companies?+
This index holds 1024 property titles in the W1G postcode district whose registered owner is a company or organisation, not a private individual — spread across 672 distinct entities. HM Land Registry publishes corporate and overseas ownership but not individual owners, so this is the corporate slice of ownership in Harley Street.
How much of W1G is owned from overseas?+
Around 13% of the corporate-owned titles indexed in Harley Street are held through a company registered outside the UK — typically in jurisdictions such as Jersey, the British Virgin Islands or Guernsey. Overseas ownership is recorded by HM Land Registry in the OCOD dataset.
Can I see who owns a specific building in Harley Street?+
Ownership here is matched to a location by postcode, because HM Land Registry does not publish a link between title numbers and mapped parcels. It's a screening indicator: it tells you which companies hold property in W1G and roughly where, but to confirm the owner of one specific building you'd order an official copy of the register for that title.
How does ownership relate to planning constraints in W1G?+
Ownership tells you who holds the land; planning constraints tell you what can be done with it. Planning Constraints combines both — check any address in Harley Street to see conservation areas, flood zones, listed buildings and 50+ datasets, alongside the corporate-ownership picture for that postcode.
Ownership is drawn from HM Land Registry’s corporate (CCOD) and overseas (OCOD) ownership datasets and aggregated by postcode district. HM Land Registry does not publish a link between title numbers and mapped land parcels, so this is a district-level screening indicator, not a title-plan boundary. We show the owning company, its jurisdiction, category and holding counts — not exact property addresses (their use is licence-restricted). Private individuals are never included; these datasets cover companies and organisations only.

Note: Corporate ownership reflects HM Land Registry’s record of the current registered proprietor and can lag transactions by weeks or months. Ownership is matched to a location by postcode, not by title-plan boundary, so treat it as a screening indicator — always confirm with an official copy of the register before relying on it.
