These United Kingdom foundations include large, established organizations as well as younger, mid-sized entities. Many are focused on social impact, research, and infrastructure. For example, Arup is a global design and consulting firm, Lloyd's Register provides engineering and technology services for critical infrastructures, and Wellcome Trust is a global charitable foundation supporting health research. The Social Mobility Foundation works to open opportunities for young people, and Crown Agents is an international development organization.
A notable pattern among these foundations is their significant concentration in London, with a majority of the listed organizations having their headquarters in the capital. While many are non-profit organizations, the list also includes entities involved in design services, maritime transportation, and beverage manufacturing, indicating a diverse range of activities.

Turn this list into pipeline
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 11, 2026.
