These Facilities Services companies in the United Kingdom are mostly large, well-established firms offering a comprehensive range of services. Companies like Mitie provide security, engineering, cleaning, and landscaping, while OCS offers cleaning, catering, and security. Ambius United Kingdom specializes in interior and exterior landscaping, and ISS Facility Services UK focuses on sustainable workplace solutions. Many of these firms, such as Bidvest Noonan and Atalian Servest UK & Ireland, provide integrated facilities management.
A notable pattern among these companies is their widespread presence across the UK, with headquarters in various cities beyond London, including Crawley, Weybridge, and Watford. While many were founded in the late 20th century, such as Mitie (1987) and Mears Group PLC (1988), some, like OCS, have a history stretching back to the early 1900s, indicating a mix of long-standing and more recently established large enterprises.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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 12, 2026.
