London's Property Company Density Map
1 in 6 active companies in prime London postcodes are property vehicles. The offshore-freeholder panic is 0.01% of the picture.
Of 51,728 active limited companies registered in 42 prime London postcode districts in May 2026, 8,805 (17.0%) are property-related by name — freeholders, RMCs, management companies, leasehold vehicles. A further 6,903 (13.3%) declare a real-estate SIC code. Only 6 (0.0%) have a registered office in an offshore jurisdiction — far below the figure the tabloid coverage of leasehold suggests. Data sourced live from Companies House.

Prime central London does not contain that many functioning businesses. It contains property. A search of the Companies House public register for the 42 most prestigious London postcode districts returns 51,728 active limited companies. Of those, 8,805 — roughly one in six (17.0%) — carry a name that broadcasts what they actually do: hold a freehold, manage a block, run a leasehold, develop a site, sit on land.
The distribution is not uniform. E1W tops the chart — 23.5% of all active companies registered there are property vehicles by name alone, before we even check the SIC codes. The runners-up are a tour of London's leasehold heartland: W1H, NW3, E14, W1K. The further into office-district territory we go (W1S, W1J, Fitzrovia) the lower the share, replaced by trading companies, tech offices and creative agencies.
And the offshore freeholder? Despite a decade of broadsheet coverage warning UK buyers about flats owned through Jersey, Guernsey or BVI structures, only 6 out of 51,728 active companies — 0.0% — had a registered office in an offshore jurisdiction at the time of writing. That is not the panic-inducing number readers have been led to expect.
A caveat matters here. Registered office country is not the same as beneficial ownership. A company can be UK-incorporated with a London registered office and still be owned through a chain of overseas trusts. Companies House does not publish ultimate beneficial ownership by default — only the “persons with significant control” (PSCs), and even that disclosure has well-documented gaps. The figure above counts only the most-visible offshore signal: the office address on the public register.
But within that limitation, the data points one direction: the typical London leasehold flat is not held by a Cayman vehicle. It is held by an English limited company sitting at a service address in W1, owned by — if you trace the PSCs — a director with a London postcode. Property concentration is the real story. Offshore concentration is mostly a moral panic keyed to a small number of high-profile cases.
“One in six active companies in prime London exists to hold or manage property. Only 6 of 51,728 — 0.01% — sits at an offshore address.”
The contrast: prime postcodes with the fewest property vehicles
Same filter (≥200 active companies). These are the prime postcodes that read more like office districts than leasehold neighbourhoods.
Where the offshore registrations actually sit
Among the 6 active companies in our sample with an offshore registered-office country, the breakdown:
- Panama4
- Cayman Islands1
- Isle Of Man1
Reminder: this counts only the registered office country, which a UK company can change in a single filing. It does not capture offshore beneficial ownership held through nominees or trusts — that data is structurally not in Companies House.
Methodology
Sample. Forty-two prime London postcode districts spanning Mayfair, St James's, Marylebone, Knightsbridge, Belgravia, Chelsea, Kensington, Notting Hill, Hampstead, St John's Wood, Islington, Wapping, Canary Wharf, Stratford and the south-bank corridor. The set was chosen for press-relevance, not statistical representation — these are the postcodes where leasehold structures and property-holding companies are most visible.
Data source. Companies House public register, accessed via the public data API, advanced-search endpoint, filtered by registered office location. For each postcode we requested up to 5,000 records; where a postcode has more than 5,000 active companies the sample is capped (the eight postcodes in our set capped at 5,000 have been flagged inline in the ranked table).
“Property-related” classifier. A name-based heuristic. A company is flagged property-related if its registered name contains one of: PROPERTY, PROPERTIES, FREEHOLD, LEASEHOLD, ESTATE, LAND, MEWS, TERRACE, GARDENS, WHARF, QUAY, COURT, MANSIONS, MANAGEMENT, RESIDENTS, RTM, ENFRANCHISEMENT, REALTY, DEVELOPMENTS, HOLDINGS, INVESTMENTS. This will over-count (a “Management Limited” might not be property) and under-count (proper nouns that don't include a hint are missed). It's directional, not absolute. The SIC code 68xxx (real estate activities) is shown alongside as a second signal.
“Offshore” classifier. A company is flagged offshore if its registered office'scountry field matches one of: Jersey, Guernsey, Isle of Man, British Virgin Islands, Cayman Islands, Gibraltar, Bermuda, Luxembourg, Panama, Bahamas, Liechtenstein, Marshall Islands, Seychelles. This captures only registered office country, not country of incorporation, and not beneficial ownership via trust or nominee structures. The 0.01% figure is therefore a strict lower bound on offshore exposure.
