Frequently asked
How much of SO4 is owned by companies?+
This index holds 17 property titles in the SO4 postcode district whose registered owner is a company or organisation, not a private individual — spread across 7 distinct entities. HM Land Registry publishes corporate and overseas ownership but not individual owners, so this is the corporate slice of ownership in SO4.
How much of SO4 is owned from overseas?+
Around 0% of the corporate-owned titles indexed in SO4 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 SO4?+
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 SO4 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 SO4?+
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 SO4 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.
