While Wills will relinquish managerial control, he will take up the new post of chairman, and finance director Steve Szabo will become director of finance and operations.
Jenkins said: "Peter has obviously contributed greatly to the company's development and growth but felt it was time to move on from day-to-day management.
"He'll still be very much involved with Snap Surveys working on special projects."
Snap Surveys was founded in 1981 by Wills and Jenkins and now offers clients a range of services in the UK, mainland Europe and in the US.
