Six phases: scope the entities → search by number and name → verify each match → consolidate on title number → escalate selectively to official copies → record the basis and the limits. Phase one is the one most often skipped, and skipping it is what produces confidently wrong answers.
Phase 1 — Scope the entities
Before any property search, establish which legal entities could hold the assets. In a group structure this determines whether your answer is complete or empty.
- Confirm the exact legal entity and its full eight-character registration number, leading zeros intact.
- Record the incorporation date — your filter for impossible matches.
- List all former names with change dates from the filing history.
- Identify parent and subsidiaries from filed accounts, where the notes usually list subsidiary undertakings.
- Check companies at the same registered office and companies sharing directors for unlisted vehicles.
- Note status — active, dormant, in liquidation, dissolved — as it changes how a proprietor entry reads.
- Note whether any entity is incorporated outside the UK, which moves it into OCOD.
Method for structured groups: tracing property through group companies and SPVs.
Phase 2 — Run the search passes
- Number pass for every entity. Precise, high confidence, no false positives.
- Name pass for every current and former name. Tolerant matching, so treat output as candidates.
- Name-variant pass — suffix forms, punctuation, ampersands, abbreviations, truncations.
- Director pass where the structure is opaque and you suspect unidentified entities.
- Address pass where you know a site and need to confirm which entity holds it.
- OCOD check for any overseas entity.
Phase 3 — Verify every match
Four checks per row. Rows that fail are discarded, and you record why.
| Check | Fails when |
|---|---|
| Registration number matches the Companies House record | Same name, different number — a different company |
| Proprietor address is consistent with a known address | Complete mismatch with no explanation |
| Proprietorship category fits the entity type | Local authority category for a limited company |
| Date proprietor added post-dates incorporation | Title registered before the company existed |
Phase 4 — Consolidate
- De-duplicate on title number, not address. Titles are the stable key.
- Preserve entity attribution — which company holds which title is a finding in itself.
- Separate tenure layers. Freehold and leasehold rows over the same building are different interests; mixing them inflates the portfolio.
- Flag multiple-address titles, which represent many units on one title.
- Fix your counting unit — titles or addresses — and state which.
- Note empty entities. A subsidiary with no titles is informative.

Work through the checklist
Search by company number, name, director or address, verify the matches, and export the consolidated set.
Phase 5 — Escalate selectively
Screening is free; official copies are £3 per title at the time of writing. Order for the titles the matter actually turns on:
- The subject property — always.
- Titles where encumbrance matters. Charges, restrictions and notices are absent from the dataset, so their absence there tells you nothing.
- All leasehold titles in scope, since tenure alone reveals nothing about term, rent or restrictions.
- Titles with an anomalous proprietor address or category.
- Titles flagged with the additional-proprietor indicator, where the visible data is incomplete by construction.
- Title plans wherever extent, boundaries or access are in issue.
Where the register shows a different proprietor from the dataset, the register governs — and the fact that ownership recently changed is usually itself material. See CCOD vs the title register.
Phase 6 — Record the basis
This phase is what makes the work defensible months later. Record:
- Dataset publication month searched.
- Every entity searched, with registration numbers, and every name variant used.
- Matches accepted and rejected, with reasons for rejection.
- De-duplication rule and counting unit.
- Titles escalated to official copies, and why those.
- Stated limitations — the standard set below.
The limitations paragraph
Include, in substance: the data covers registered corporate ownership in England and Wales only; it excludes individually held and unregistered land; overseas proprietors are recorded separately in OCOD; it records registered rather than beneficial ownership; it does not record charges, restrictions, covenants, boundaries or lease terms; price paid is incomplete and not a valuation; and registration lags completion, with monthly publication adding further delay.
The full treatment is in what CCOD does and does not tell you.
Red flags worth escalating
- Nil return from a company that plainly trades from premises — likely an unidentified entity, an offshore holder, or a former name.
- Proprietor address unconnected to the company — investigate before relying on the row.
- Recent date proprietor added on a key asset — ownership has just changed; find out why.
- A cluster of same-day incorporations holding one title each — a fund or scheme structure with vehicles you may not have all of.
- Additional-proprietor indicator set — the visible proprietors are not all of them.
- Freehold and leasehold over the same site in related entities — an intra-group lease, with implications for value and security.
- Overseas proprietor — check the Register of Overseas Entities for beneficial ownership.

Frequently asked questions
What should a corporate property due diligence checklist cover?
Entity scoping at Companies House, ownership searches by number and by name including former names, identity verification on each match, consolidation and de-duplication on title number, selective escalation to official copies of the register, and a written record of the search basis and its limitations.
What is the most commonly missed step?
Entity scoping. Searching only the company you were given, rather than establishing which entities in a group could hold the assets, produces incomplete answers and — in SPV structures — nil returns that are actively misleading.
When should I order official copies of the register?
After screening, for the titles your matter actually turns on. Order registers whenever you need charges, restrictions, covenants or the full proprietorship entry, and title plans whenever extent matters. Screening first is what keeps the per-title fee proportionate.
