Frequently asked questions
How many companies are registered at SW1Y 4JS?▾
21 companies are registered at SW1Y 4JS on the Companies House register. A postcode covers roughly fifteen addresses, so a high count usually means one building — a formation agent, an accountant or a serviced office — rather than a busy street.
Why do so many companies share one address?▾
A registered office is where official post is served, not where the business happens. Formation agents and accountants offer their own address for that purpose, so a single building can hold thousands of registrations. It says nothing about any of them on its own — but it does mean the address tells you nothing about the business either.
Is this the address the business trades from?▾
Not necessarily. The register records the registered office, which is a legal address for service. Many companies trade somewhere else entirely, and nothing requires the two to match.
Where does the location come from?▾
The ONS Postcode Directory, which places every UK postcode. The companies come from the Companies House register. Both are published as open data and refreshed on a schedule — a company incorporated in the last day or so may not be here yet.
