Cleanology is a commercial cleaning company providing professional office and commercial cleaning services. The company was founded in 1999 by the mother and son team Elisabeth and Dominic Ponniah. Dominic—now chief executive—originally planned to help out his mother with her new business on a short term basis, but stuck with the business as it grew. The company began with a single client and one cleaner but has now expanded to 1,400 employees from 34 countries. Cleanology’s clients include large corporates and royal palaces, with the company offering a range of services across London and other major UK cities. Cleanology’s high-profile customers have helped sales grow from £8.6m in 2021 to £22m in 2023.
