Sharp, who was at the firm for three years, passed away last Thursday aged 43.
Network Data appointed representatives paid tribute to Sharp on their site Botleys Forum.
It says: “I understand from both his former and current colleagues that he was a fine and decent man who will be greatly missed.
“On behalf of all members of Botleys Forum, I would pass on our sincere and heart felt condolences to Craig’s friends and colleagues but more especially to Craig’s family. Our thoughts are with them.”
Sharp qualified as a chartered accountant in 1995 having trained with Howarth Clark Whitehall LLP.
He left Howarth Clark Whitehall LLP in July 2005 to join Network Data and head up the group’s finance department.
The network is in the middle of offering its ARs a new contract with the Lighthouse Group, after its Financial Services Authority permission was taken away.
