Four workflows, one principle: establish the entity list or the address fragment first, screen at no cost, then escalate to £3 official copies only for the titles the matter turns on. The commonest time sink is searching the wrong entity — and that is a Companies House problem, not a property one.
Workflow 1 — Diligence on a target company
Use when: acting on an acquisition, a refinancing, or any transaction where you need the asset perimeter of a corporate target.
- Scope entities at Companies House. Full registration number with leading zeros, incorporation date, former names, subsidiaries from the filed accounts, registered office history.
- Number pass for every entity — precise, no false positives.
- Name pass for current and former names — tolerant, so filter the output.
- Verify each match on number, proprietor address, proprietorship category, and date-added against incorporation.
- Consolidate, de-duplicating on title number, preserving which entity holds which title.
- Triage and escalate: official copies for the material assets, all leasehold titles in scope, anything with an anomalous proprietor entry, and any title flagged with the additional-proprietor indicator.
Where it goes wrong: step one gets skipped. A parent-only search on an SPV-structured group returns nothing, and a nil return read as "no assets" is worse than no search at all. See tracing property through group companies and SPVs.
Workflow 2 — Site assembly and development
Use when: assembling a site, checking access, or identifying every interest across a block.
- Run the postcodes across the target area first — the widest useful net for a defined geography.
- Run each street name without numbers, to catch descriptive entries such as "land on the north side of…" that no numeric search will match.
- Map the freehold titles. Filter to freehold so you are looking at the ownership layer rather than occupational interests.
- Look for the discontinuities — the parcel with a different proprietor, the strip with no postcode, the access route on its own title. These decide whether a scheme works.
- Check multiple-address flags. One flagged title can cover a large part of your site, which simplifies the assembly considerably.
- Order title plans for every parcel where extent or access is in issue. This is the workflow where plans matter most, and the dataset holds no boundary information at all.
Where it goes wrong: searching only formatted addresses and concluding that unnumbered parcels are unregistered. Those parcels are frequently the ransom strip.
Workflow 3 — Counterparty and landlord identification
Use when: a lease event, a dilapidations claim, a rent review, or you need to know who you are actually dealing with.
- Search the building, not the unit — a distinctive fragment of the address.
- Read the tenure layers. Freehold is the investment owner; a long leasehold over the whole is an intermediate landlord; unit-level leaseholds are occupiers.
- Check date proprietor added. A recent date means the counterparty named in a lease signed years ago is no longer the party you are dealing with — investment assets change hands regularly.
- Take the registration number to Companies House for accounts and covenant strength.
- Order the official copy before serving anything with legal effect. Serve on the register, not on a monthly snapshot.
Where it goes wrong: assuming the freeholder is your landlord. In a head-lease structure your immediate landlord is the intermediate leaseholder, and the managing agent you actually speak to appears on no register at all.

Run the workflow
Search by company, number, director or address, verify the matches, and export the consolidated set.
Workflow 4 — Asset tracing and enforcement
Use when: assessing whether there are assets worth pursuing, or identifying the correct respondent.
- Start from the person if the corporate structure is unknown: resolve their Companies House appointments, then check each connected company. See director property search.
- Widen from every entity found — shared registered offices and shared officers surface siblings the appointments alone missed.
- Search both CCOD and OCOD. Offshore vehicles are common at the value levels that make enforcement worthwhile.
- Check the Register of Overseas Entities for any overseas proprietor — for offshore structures this can get you closer to beneficial ownership than anything available domestically.
- Order official copies for the material titles: charges tell you who ranks ahead of you, and restrictions tell you what can be done with the asset.
Where it goes wrong: conflating a directorship with ownership. A director may hold no shares and no beneficial interest. The defensible formulation is "companies at which X holds an appointment are registered proprietors of…", not "X owns…".
Escalation points, in one place
| Trigger | Order |
|---|---|
| Anything with legal effect — notice, exchange, completion | Official copy of the register |
| Any question about charges, restrictions or covenants | Official copy of the register |
| Any question about extent, boundaries or access | Title plan |
| Leasehold title in scope | Official copy — tenure alone says nothing about terms |
| Additional-proprietor indicator set | Official copy — visible proprietors are incomplete |
| Anomalous proprietor address or category | Official copy, plus Companies House |
| Recent date proprietor added on a key asset | Official copy — find out what changed |
Recording the work
For every matter, note the dataset publication month, the entities and name variants searched, which matches were accepted and rejected and why, the de-duplication rule and counting unit, and which titles were escalated. Then include the standard limitations: registered rather than beneficial ownership, no charges or boundaries, England and Wales only, individuals and unregistered land excluded, registration lag.
The checklist form is in the due-diligence checklist.

Frequently asked questions
What is the fastest way to identify a commercial property's owner?
Search the most distinctive fragment of the address — building name, or number and street — rather than the full postal address, because register addresses are free text and rarely match a formatted address exactly. Then read the tenure field to identify which layer of ownership each returned row represents.
How do legal teams avoid over-ordering official copies?
By screening first. Identify the candidate titles from ownership data at no cost, triage them by relevance to the matter, and order official copies only for that shortlist. On a portfolio of any size this is substantially cheaper than ordering speculatively, and the escalation decisions are defensible.
What is the biggest time sink in these searches?
Searching the wrong entity. If the client gives you the trading company and the assets sit in SPVs, every subsequent step is wasted. Establishing the entity list from Companies House before running any property search prevents it.
