Sherry continues to manage sales but will take on responsibility for driving the business forward. She replaces Pierre de Winter, who has retired.
Sherry said 2006 had been a successful year for the company and that it was poised for another good year.
"I am confident I have a good grasp of our business and the position of Spadel UK's water brands," she said. Sherry joined Spadel in 2002 from Hall and Woodhouse, where she was trade sector manager.
