How many companies are registered at an address?

Some UK postcodes host tens of thousands of registered companies — a single building can be the registered office for a whole industry of paper companies.

Search any postcode here (or click the postcode on any company page) to list every company registered there. Each company page also says how many others share its postcode — a useful signal for telling a trading premises from a formation agent's brass plate.

A high count is not itself suspicious: accountants, formation agents and virtual-office providers legitimately host thousands of registered offices.

The registered office on file is at Companies House; it is an address for correspondence, not necessarily where the company trades.
