Former Lancashire batsman Lloyd - the son of former England player and coach David Lloyd, who was also a first-class umpire - played six one-dayers between 1996 and 1998, as well as amassing more than 17,000 runs for his county. He took up umpiring in 2008.
Wharf started umpiring after his retirement in 2009 and was added to the ECB's reserve list three years ago. The Yorkshire-born seamer spent most of his playing career with Glamorgan and took 18 wickets in 13 ODIs for England between 2004 and 2005.
"We are delighted to welcome Alex and Graham onto the full list for 2014," the ECB's chief executive, David Collier, said. "These promotions are richly deserved and reflect the quality of Alex and Graham's performances in last season's domestic competitions and their high levels of commitment and professionalism overall."
