Mr Jamieson joined Keltruck in 2007 and leaves the company in a very strong position having achieved the best results in the company’s 32 year history over the past three years, with 2015 looking to be the best ever.
Commenting, Mr Jamieson said: “The company is in a fantastic shape for the future and I’m sure it will continue to go from strength to strength over the coming years too.
“Whilst it is exciting to be taking up my new role at Scania (Great Britain) Limited I am sad to be leaving Keltruck and would like to wish my colleagues at the company all the best for the future. We will be dealing with each other in the future as colleagues within the Scania UK network.”
Chris Kelly, chairman of Keltruck, said: “Andrew will be missed by all at Keltruck having steered the company to year-on-year growth. Andrew’s will be big boots to fill and an announcement on any successor will be made in due course.”
