13,904 companies, one address: 3rd Floor, 86-90, London
3rd Floor, 86-90, London EC2A 4NE is one of the busiest registered-office addresses on the UK company register. This page is the public-record profile of the address itself: how many companies are registered here, how fast new ones arrive, and what they do, from the Companies House snapshot of 2026-08-01.
Why are thousands of companies registered at one address?
Because a registered office is a legal service address, not premises. Every UK company must have one, it must be a real address, and nothing requires anyone to work there. Registered-office and company-formation services rent exactly that: a compliant address that receives official mail, which is why a single building can lawfully host tens of thousands of companies. It is an ordinary, regulated part of how UK incorporation works, and it is especially common for home-based founders who would rather not publish their home address on a public register.
What that means when you read a company record
The practical consequence for anyone reading the public record: a company's registered office says where its paperwork goes, not where it trades. Treat the address as an administrative fact, and look at filings, officers and the company's own website for the substance. That distinction is exactly why our own enrichmentverifies a company's real website and contact details rather than trusting the office address.

Two things worth knowing
If this is your address, and how current this page is
If this is YOUR address and it should not be: a company using an address without the right to do so can be reported to Companies House, which can move its registered office to a default address. Our guide to a business being registered at your address walks the RP07 process. That applies to individual misuse; the service addresses profiled here host companies with permission, which is the ordinary case.
How current this page is: figures refresh with each monthly register snapshot, alongside our UK company formations tracker. A company that moved or dissolved yesterday still shows until the next snapshot.
