Transform Cosmetic Surgery Group has appointed twentysix as its digital agency following a competitive pitch.
The Leeds-based agency said the contract, which will see it redevelop Transform's existing website, was worth "six figures".
Gail Dudleston, CEO of twentysix, said: "This is a fantastic win for us and one that we are really excited about delivering in the New Year. Routed in a detailed digital strategy, the overall solution we deliver for Transform will be one that focuses on consumer engagement."
The first phase of the website will launch in spring with a second phase later in the year.
Transform's current website was launched by Carpe Diem in July 2010.
