Nick del Rio has been appointed as Glass's Western Europe managing director, which includes responsibility for the UK business.
Del Rio joins from business intelligence company Informa, where he was director of the business information division. He will be based in the UK.
Glass's UK interim managing director Ed Hummel has left the business to take up a position as commercial director at Essential Fleet Solutions.
Essential Fleet Services is a Lincoln-based contract hire and leasing company backed by private equity investors, Endless LLP.
Essential has operations spanning the North West, Yorkshire, Lincolnshire and the South East, and has a turnover of approximately £43 million.
Ray O’Toole, Essential Fleet Services chief executive, said: “Ed will be a great asset to the business and an energetic member of our senior management team and board, supporting Essential to achieve our significant growth ambitions.”
Hummel was promoted from sales director to managing director at Glass's in September 2014.
He was promoted following Ian Tilbrook's departure from the business.
