“Principle Cleaning Services Limited have provided cleaning services at Crédit Agricole CIB, London Branch for nearly 10 years. During this time Principle have proved to be professional, trustworthy, responsible and flexible at all times. Over the years we have developed a strong partnership, from the cleaning team on the ground to the managing director. The dedication from Principle employees to provide a first class service and to adapt quickly to change, (more now than ever with the Covid-19 pandemic) has proven to be a successful collaboration.”

Jason MatthewsGeneral Services Manager

“It is encouraging that after working with us for over five years, Principle have been able to demonstrate through competitive tender that they can still provide the best service proposition whilst remaining price competitive. We look forward to working with them to introduce the new initiatives that they have proposed.”
