Robinson joins from Mace where he spent 15 years most recently as Operations Director on the Heathrow expansion programme.
He takes over from Rob Lynch who is stepping down at the end of this month after 20 years at the company.
Robinson said: “I am definitely joining at an interesting time, but I am very excited by the massive potential.
“Lyndon SGB has some great foundations; I have been impressed by the commitment to safety and the wellbeing of everyone we come into contact with.
“Our plan is to make Lyndon SGB the scaffolding contractor of choice on a national basis.
“Our ability to offer all types of scaffolding while being supported by mast climbers and our market leading hoist provider, Taylor’s Hoists, means we can provide clients with a unique integrated service.”
Lynch added: “Although I am sad to be going, I am absolutely sure that the business is in safe hands, Stuart and the team have all the skills to make Lyndon SGB the UK market leader in scaffolding, I wish them all the very best.”
BrandSafway purchased Lyndon Scaffolding and Taylor’s Hoists in January 2019 combining the businesses with SGB to create Lyndon SGB.
