Churchill Group welcomes Principle into its group of specialist businesses
Churchill Group today announced that Principle, one of London’s most established specialist commercial cleaning providers is joining its group of specialist businesses and merging with Portfolio.
With more than 37 years of experience and a strong reputation for quality across London’s landmark buildings, Principle will continue to operate under its well‑recognised brand as part of Churchill’s group of specialist businesses.
The Principle and Portfolio brands merging bring together two culturally aligned, employee‑owned organisations that share a belief in empowering teams, building long‑term client partnerships and delivering positive social impact through responsible business practices. Principle’s decision to join Churchill was strongly influenced by the group’s employee‑owned structure and people‑first culture, ensuring colleagues remain at the heart of the business.
As Churchill strengthens and simplifies its specialist cleaning capability in London, its Portfolio cleaning brand will transition into Principle over the coming months. This integration brings together the strengths of both organisations to create a single, unified specialist cleaning offer for clients.
Clean environments make people happier
Our core belief is that clean, hygienic spaces improve how people feel, behave, and engage at work.
Our cleaning teams have the freedom to work in a flexible, responsive way. They stay focused on helping clients keep clean and safe spaces. This ensures we provide high-quality services with dependable, consistent delivery.
Alongside our general, specialist, window, and washroom cleaning services, we provide water hygiene support. We also offer grounds maintenance, pest control, and full waste management services.
