The computer games sector in England features a mix of established developers and specialized service providers. Companies like Side offer extensive technical and creative solutions, while Testronic focuses on QA, localization, and player support. Publishers such as Square Enix distribute iconic games, and Jagex: The RuneScape Company creates long-lasting interactive titles. Non-profit organizations like Women in Games also contribute by promoting equality within the industry.Many of these larger firms are based in London, which appears to be a central hub for the industry. However, significant development studios are also found in cities like Cambridge, with Jagex and Frontier Developments, and Sheffield, home to Sumo Digital Ltd. This geographical spread indicates a robust and diverse ecosystem for computer game development across England.

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.
