He and his team floated this on AIM in 2005 with a market capitalisation of £25 million. With his team he grew this business from zero turnover in 2000 to £100m turnover and £6m profits before retiring as Chairman in 2008. It reached a market capitalisation of over £300m and has now transformed into Blancco.

Shields Environmental continues to be a very successful business in the telecoms sector.
