These are large recruitment and staffing agencies in the United Kingdom. Many are headquartered in London, with a few in nearby towns like Addlestone and Hemel Hempstead. The companies listed span diverse specializations, from general recruitment to niche sectors.

## 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.
