abgDeep Kleen Services has been ABG’s cleaning company for 9 years. They are a very approachable, flexible and down to earth bunch who offer solutions to any cleaning problems I may have.

Royal Society for the encouragement of Arts (RSA)


The RSA building at John Adam Street is a remarkable example of 18th Century architecture and we are very proud of its heritage. The home of The Royal Society for the encouragement of Arts, Manufactures & Commerce since 1754, it is now a multi functional building offering banqueting halls, conference facilities, a library and office suites. The Grade 1 listed building is set on seven floors comprising 35,000 square feet.

Our cleaning requirements are very complex and we require a cleaning company that not only clean to a very high standard but also fully understand our philosophy of delivering an outstanding service to our customers. We are passionate about our business and the facilities we provide and we feel that these sentiments are echoed by the team at Deep Kleen Services.

Deep Kleen provides us with experienced and committed operatives who are very thorough in their tasks. The team is lead by a supervisor and we also have a dedicated Site Manager who visits every day to double check that all our requirements are met. This structure of management is very reassuring to us and gives us the confidence to continue to deliver our own Customer Service Promise: to be consistent in the standard of services we provide.
