To mark the prestigious occasion of its twentieth anniversary last year, Principle Cleaning Services Ltd held a celebratory event for staff, clients, suppliers and guests. Valued client of the company, Christie's kindly played host and provided an exquisite room for the evening. Over 150 guests were privy to a unique exhibition of 20th Century British art, including a coastal scene that Sir Winston Churchill had painted during the 1930s, in which he demonstrated his fascination with the sea breaking on the shore. Also a team of 14 staff from Principle Cleaning Services once again ran the London 10K in July to raise valuable funds in support of the company's chosen charity The London Centre for Children with Cerebral Palsy.
