Grade One


Company History

In the early '90's, following a distinguished career with the Royal Marines and a few years working for a family business, Jim Corrigan decided to start his own cleaning company......and so on 21st February 1995 Grade One Commercial Cleaning Services Ltd was born.

Having since travelled through two recessions, a dotcom boom and nearly five general elections, Grade One is still going strong with an enviable reputation for providing a competitive, innovative and high quality customer service.

Stephen Corrigan has been with the business all his working life. Starting out as a window cleaner and moving through supervisory and area management positions, he was appointed Managing Director in 2010 and now, with the support of his senior team, looks after the strategic direction of the company.

Despite the recent economic downturn, Grade One has managed to enjoy a strong client retention rate and in fact with the recent award of some prestigious contracts, expects continued success over the coming years.

With over 400 staff, Grade One are celebrating their 20th anniversary by rebranding the company, putting in place a strong marketing campaign focussed around growth, investing in technology including a dynamic customer portal and website, and increasing their delivery offer to include additional FM services.
