This selection of large companies in England spans diverse sectors, with a notable concentration in London. RELX provides information-based analytics, Balfour Beatty plc is a global infrastructure group, and the University of Oxford is a prominent higher education institution. Centrica focuses on sustainable energy services, while Smollan partners with brands and retailers.

How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
