The identity, created by Sheffield-based agency Uber, includes logo design and style guidelines for stationery and the charity's website.
Start was created by arts graduate Leah Pattison in August 2000 and is committed to improving the lives of women in India suffering from leprosy. The logo carries the strapline "Empowering Women in India".
Pattison said: "The team at Uber have donated their time and services, which has given Start a fantastic new image without the charity's money being diverted from the real cause."
The new identity will launch on June 1.
