UK E-commerce Companies — How Many Are There in 2026?

E-commerce is now one of the largest business sectors in the UK by company count. There are approximately 192,486 active e-commerce and online retail companies registered at Companies House as of March 2026 — making it the fourth largest sector after property, management consultancy, and construction.

E-commerce Companies by Region

London's Dominance

London accounts for over 43% of all UK e-commerce companies — a far higher concentration than in most other industries. This reflects the capital's role as a hub for online retail, dropshipping, Amazon FBA sellers, and direct-to-consumer brands. Many of these are micro-companies with one or two people.

International Ownership

E-commerce has one of the highest rates of international PSC ownership after IT consulting. This makes sense — online retail has no geographical barriers to entry, and the UK's business-friendly company formation process makes it easy for overseas entrepreneurs to set up a UK entity. Our data shows significant numbers of Chinese, Indian, and American nationals controlling UK e-commerce companies.

Northern Ireland's E-commerce Scene

With 4,245 active e-commerce companies, Northern Ireland has a surprisingly strong online retail sector relative to its population. This may reflect the advantages of UK and EU market access, lower operating costs compared to London, and a growing tech-savvy entrepreneurial culture.
