Our story

Built on experience, service and long-term relationships

So Clean was established by Simon Gasson in 1994. From the beginning, the business was built around practical experience, with Simon working hands-on alongside cleaning operatives and developing a clear understanding of what clients need from a dependable cleaning partner.

In 1996, Simon’s brother Nicholas joined the company. After gaining operational and supervisory experience, Nick became a partner in the business and now supports the company’s continued growth through his involvement in finance, purchasing and wider company operations.

Today, So Clean combines professional cleaning teams, modern equipment, strong operational support and a responsive help desk facility to provide a service that is flexible, reliable and easy to work with.
