First Cleaning Contractor In Europe To Achieve CIMS Accreditation


  • Launched by global association ISSA, the Cleaning Industry Management Standard (CIMS) is the first consensus-based management standard that outlines the primary characteristics of a successful, quality cleaning organisation.
  • Principle Cleaning Services is the first cleaning company in Europe to be accredited with this certification. This means that choosing Principle Cleaning as your cleaning service provider allows you to gain an increased level of confidence in your contractor by using CIMS as a powerful pre-qualification tool.
  • CIMS is strongly supported by the International Facility Management Association (IFMA) and more and more facility managers, purchasing professionals and others are citing CIMS in their requests for proposal and cleaning specifications.


  • In February 2014, Principle Cleaning Services became a recognised Living Wage Foundation provider
  • We have been a long term supporter of the Living Wage and have presented cleaning options based on our staff receiving the London Living Wage to existing and prospective clients.
