The short version
- Off-market means not listed on Rightmove, Zoopla, OnTheMarket, EG Propertylink, or with a commercial agent. It does not mean "secret"; it means reachable only by approaching the registered owner directly.
- Almost every UK commercial property of any scale is held by a limited company. Companies House plus HM Land Registry plus the London Gazette are the three primary public sources that, together, let you identify the actual decision-maker behind any commercial title.
- The most predictive sell signals stack: bridging-finance maturity, multi-year late filings, director age over 65, dissolution filings on a holding SPV, formal Gazette events, charge changes within an 18-month window of disposal.
- Coverage is England and Wales. HM Land Registry does not extend to Scotland or Northern Ireland.
- Direct-to-vendor outreach works when the recipient is the actual decision-maker, the letter references something specific about the holding, and the timing matches a real catalyst rather than a generic mailshot.
What "off-market" actually means in UK commercial property
"Off-market" is one of the most misused phrases in the UK property industry. Some agents use it for a listing they have not yet announced. Some buyers use it for any deal they did not see on a portal. Both miss the structural point.
Off-market commercial property, in the form GalimAI tracks, means an asset where:
- The property is not currently advertised on any of the major UK commercial channels (Rightmove Commercial, Zoopla, OnTheMarket, EG Propertylink, RightBiz, the major commercial agents).
- The registered owner has not formally instructed an agent on a sale.
- The owner is reachable only through direct outreach to the registered office, typically by post to the director or person with significant control.
This is a meaningful chunk of the actual sellable market. The genuinely motivated commercial owners — estate-driven sales, retirement disposals, refinancing pressure, distressed holdings, ground-up developers cycling capital — disproportionately solve the disposal privately. Their advisors call two or three known buyers; the asset never reaches the open market. The agent-listed market is the same fish in the same pond for everyone. Off-market is where the inventory the rest of the market never sees actually moves.
Where the data lives: three primary UK sources
UK commercial property ownership is unusually transparent compared with most jurisdictions, because three public registers can be cross-referenced to produce a near-complete picture of any commercial holding.
1. Companies House
The UK registrar of companies. Maintained under the Companies Act. Records every limited company in the UK, including the directors, persons with significant control (PSCs), registered office, annual accounts filings, and crucially every charge registered against the company. Almost every UK commercial property of meaningful value is held through a limited company, so Companies House is the base layer for commercial ownership analysis.
2. HM Land Registry
The UK government register of land and property ownership in England and Wales. Records the legal owner (the registered proprietor) of every title, plus charges (mortgages) and transaction history. Almost all commercial freeholds and long leaseholds are registered. Land Registry does not extend to Scotland (Registers of Scotland) or Northern Ireland (Land and Property Services NI); GalimAI does not represent coverage there.
3. The London Gazette
The official UK public record for statutory notices. Includes appointments of administrators and receivers, intentions to strike off, dissolutions, charge changes, partnership dissolutions, and a range of other formal legal events. Each notice corresponds to a Companies House entity and, in property cases, points to a holding that is about to enter forced or accelerated disposal. Read more on Gazette notice types and what each one signals.
Cross-referenced, these three give you: the title, the owning entity, the people behind the entity, the entity's financial position, and the catalysts. That combination is what makes commercial off-market sourcing tractable in the UK in a way it is not in most other markets.
Who actually owns UK commercial property
Across the more than 1 million UK property owners GalimAI tracks, a handful of ownership archetypes dominate the commercial side of the market. Recognising which archetype owns a given asset is what tells you whether a disposal is plausible in the next 6 to 18 months.
The single-asset SPV
One company, one freehold or long leasehold, formed specifically to hold the asset. Often used for retail parades, small industrial units, mixed-use blocks, and trophy single-let assets. SPVs frequently dissolve within 24 months of asset disposal. Conversely, an SPV approaching its second or third charge refinance, with the underlying asset held for 7-plus years, is statistically far more likely to dispose than the median holder. More on the SPV flipper pattern.
The portfolio holding company
One company, multiple titles. Common for retail multiples, smaller industrial estates, regional office portfolios. Often held alongside a parent operating company. Disposal patterns track the parent's strategic position; a portfolio holder filing accounts late while the parent is restructuring is a strong combined signal.
The family-owned commercial holding
Long-tenure freehold, often acquired in the 1990s or earlier, family directors, PSC overlap with operating businesses. The 22-year-hold cohort is heavily represented here, particularly in retail and light industrial. The dominant disposal catalyst is director age and succession; the median director age in this cohort exceeds 60.
The distressed or pressured holding
Companies running with overdue bridging finance, multiple charges past term, late filings stacked, or formal Gazette events. Distressed property companies in London and the regional distress map document this cohort across both commercial and mixed-use holdings. Disposal here is often forced rather than chosen, and the time window is tight.
The developer exit vehicle
Single-asset or small-portfolio SPV holding completed or near-completion development stock. Companies House shows development-finance charges that have either matured or are approaching maturity. Developer exit signals are some of the most time-sensitive in the dataset.
The signal stack: what predicts a commercial disposal
No single Companies House data point predicts disposal reliably on its own. A late filing, on its own, is noise. A 65-year-old director, on her own, is not a signal. What works is signal stacking: combinations of independent indicators that converge on a real catalyst.
The pattern GalimAI's sell-timing model weights most heavily for commercial holdings:
- Bridging or development-finance maturity within 12 months, on a holding company with limited refinance capacity. Bridging is a short-term instrument; running past term forces a decision. 38,000 UK property companies are currently on short-term debt; 11,000 to 15,000 have charges already two years overdue.
- Director age over 65 in combination with multi-decade tenure and no apparent succession structure. Estate planning is the single most common quiet disposal catalyst across UK commercial property.
- A formal Gazette notice: receivership, intention to strike off, or dissolution. The notice is the public announcement of a process that has already started. The Gazette buyer window documents how long this window stays actionable, by notice type.
- Multi-year late filings on the holding company, particularly where the operating parent is also late. Filing delinquency is a leading indicator of distraction or stress at director level.
- Charge changes within an 18-month rolling window: replacement charges, additional charges layered onto an existing position, or charge satisfaction without an obvious refinance source. These often signal a quiet exit being structured.
- Long tenure combined with a static or declining operating business: the family-held cohort where the underlying trading entity is no longer growing into the real-estate position, so the property is increasingly a separate, sellable asset rather than an operational base.
The GalimAI sell-timing model takes the full stack of company-level signals and ranks every property-holding company on probability of disposal in the next 6 to 18 months. Read the methodology.

The product layer sits on top of the three data sources described above. The portal at app.galimai.com lets a buyer filter the 1 million-plus property-holding company universe by sector mix (retail, office, industrial, mixed-use, development), region, signal density, tenure, charge profile, and ownership archetype. The sell-timing model ranks the resulting set so the top of every list is the segment most likely to dispose in the buyer's chosen window.
For buyers who would rather have the outreach run end-to-end, the Proprietary Sourcing managed service operates the same data inside GalimAI: letter campaigns sent to the highest-probability commercial owners for a specific buy box, with response prediction filtering the bottom-quartile of likely non-responders before any pack is printed. Hard costs to launch; success fee only on verified positive replies. See pricing.
When direct-to-vendor outreach actually works for commercial
Direct outreach to commercial property owners is not a volume game. Generic mailshots to broad lists of property-holding companies produce response rates that do not justify the postage. What works has three properties:
- The recipient is the actual decision-maker, not an administrator at the registered office. Companies House plus careful Persons-with-Significant-Control reading is what tells you which name to put on the envelope.
- The letter references something specific to the holding: the asset type, the geography, the apparent ownership history, the visible catalyst. A letter that could have been sent to any property owner gets read as junk and discarded.
- The timing matches a real catalyst, not the date you happened to mail. The best time to send letters is the window where the catalyst is fresh enough to be top-of-mind but not so far advanced that the disposal route is already locked in.
The 160,000-letter response model GalimAI trained on real outcomes consistently shows that recipients who reply share a tight profile: visible catalyst within 18 months, the right named individual, and a letter referencing the specific asset rather than a generic offer.

Common questions
What does off-market commercial property mean in the UK?
Off-market commercial property refers to UK commercial assets that are not currently advertised on Rightmove, Zoopla, OnTheMarket, EG Propertylink, or via commercial estate agents. The property is owned, the owner may be open to selling, but the asset is reachable only by approaching the registered owner directly, which in commercial UK property is almost always a property-holding company on Companies House.
How do you find the owner of a UK commercial property?
Cross-reference HM Land Registry title data with Companies House. HM Land Registry shows the registered legal owner of the title (almost always a limited company for commercial assets); Companies House gives you the directors, persons with significant control, registered office, and filing history of that company. Together they let you identify the natural person you actually need to write to.
Why look off-market for UK commercial property?
The agent-listed UK commercial market is a small fraction of total stock and a smaller fraction of motivated sellers. Most owners with genuine sell catalysts (estate-driven sales, distress, refinancing pressure, retirement) never reach the open market because their advisors solve the disposal privately. Off-market sourcing reaches that population directly before disposal terms harden.
What data sources does GalimAI use for UK commercial property?
Companies House (every UK property-holding company, directors, persons with significant control, accounts, charges), HM Land Registry (registered titles and transactions for England and Wales), and The London Gazette (formal legal notices including receiverships, dissolutions, and charge events). All three are public primary sources. We do not buy lists or scrape portals.
Does this work for both commercial and residential UK property?
Yes, although the signals weight differently. Commercial assets are almost universally held through corporate entities, so Companies House is the primary base layer. Residential investment property is increasingly held the same way (SPVs, family LLPs, BTL companies), so the methodology applies. Owner-occupied residential sits outside this approach; you would not find a family home via Companies House.
Is this approach GDPR-compliant?
Yes. Companies House and HM Land Registry data are statutory public records. Director and PSC information is published by the Registrar of Companies under the Companies Act. Reaching a company director at the registered office, in a B2B context, on a topic relevant to their corporate property holding, is normal commercial outreach and is treated as such under the UK GDPR's legitimate interests test. Vendor anonymity is preserved in all GalimAI public outputs.
Does GalimAI cover Scotland or Northern Ireland commercial property?
No. HM Land Registry covers England and Wales only. Registers of Scotland and Land and Property Services Northern Ireland operate separately and we do not represent coverage there. Companies House covers the entire UK, so Scottish and Northern Irish property-holding companies appear in the company-level data, but the property-title link is England and Wales only.
