Registry status is not enough to identify operating companies
Use the UK register to separate legal status from trading evidence, and test what an active-company list can support before using it for targeting.
If you need a list of operating companies, do not accept an “active” registry filter as the selection method. Use it to exclude entities whose legal status does not fit your task, then ask what dated evidence links each remaining legal entity to a current business. A row with no such evidence belongs in a review queue, not in a confirmed operating-company list.
The UK provides a useful example. Companies House lets you check a company’s registered name, number, status and filing history. Those are starting points for identity and legal-status checks. They do not certify that the company currently sells a product or provides a service.
Read each registry signal for its actual purpose
| Signal | What it helps establish | What remains open |
|---|---|---|
| Registered number and status | Which legal entity the record refers to and its status when checked | Whether that entity runs the business you are seeking |
| Dormant accounts for a stated period | The company reported no significant accounting transactions for that period under the Companies House test | Whether it began trading after that period |
| Recent confirmation statement | The company has made a required filing about its registered details | Whether it traded during or after the review period |
| Registered office | The official address for company correspondence | Where, if anywhere, it operates or trades |
GOV.UK defines Companies House dormancy by significant accounting transactions in a financial year. A dormant filing is useful evidence about that period, not a permanent label. The same guidance says a company does not have to notify Companies House when it restarts trading; later accounts may show the change. Conversely, a non-dormant filing alone does not identify a current customer-facing business.
A fresh confirmation statement is also easy to overread. Companies House says dormant and non-trading companies must file one. It confirms registered information, not sales, staff or an operating site.
Apply the check to a company list
For a shortlist, keep the decisions visible rather than collapsing them into one “active” flag:
- Match the entity. Use the registered number to check the live register and record the status and check date. A name alone may refer to a brand or another group company.
- Read the dated filing. Note whether the latest available accounts describe dormancy and which period they cover. Do not turn an old period into a present-day conclusion.
- Match the operating claim. Check the company’s own site or another attributable public source for what business it says it conducts. Record the source, observation date and how it connects to the legal entity. A live site is a claim, not independent proof of trading.
- Keep location separate. A UK registered office can be an accountant’s or agent’s address. Enter a trading address only when a separate source supports it; otherwise leave that field blank.
- Decide and document. Mark the row supported, excluded for the intended population, or unresolved. Leave unsupported revenue, headcount, ownership and contact fields blank. An unresolved company may still be worth further research; its uncertainty should stay visible.
This is a selection method, not a claim that public evidence can establish trading with certainty in every case. A company can operate without a website, and an old website can remain online after activity stops. For the sources and limits of the operating check itself, use the trading-evidence guide.
Test the file before relying on it
When evaluating a private-company database, choose a few companies whose public records you can inspect independently. Ask the provider which registered entity each row represents, when status was checked, what operating source was observed, and how unresolved cases and separate address fields are handled. If “active” is the only answer, the file may still suit a legal-entity map; it has not answered an operating-company targeting question. The database buyer checklist covers the wider purchase decision.

Frequently asked questions
Does active Companies House status mean a company is trading?
No. The status describes the registered entity. A company can remain on the register while dormant or not trading. Check dated filings and separate operating evidence before treating it as an operating business.
Does a recent confirmation statement establish trading activity?
No. Companies House requires dormant and non-trading companies to file confirmation statements too. The statement helps keep registered details current; it is not a trading-activity test.
Should a company with no website be removed from a target list?
No. Record that no website was found and leave operating status unresolved until other current evidence supports a decision. A website, when present, is a company claim that still needs to be matched to the legal entity.
