Agree there is no one thing to hang notability on, but he has had significant coverage in multiple reliable sources over the years and not just for one event. For instance "Refinery bid throws spotlight on investors" in ''The Sunday Times'' back in 2014; in connection with Monarch Airlines; and recently a great deal relating to British Steel so that he meets  where "multiple independent sources may be combined to demonstrate notability." The effect is cumulative. Some of it is offline so I assume you have not read that
