The website offers ranges of wild bird food from established brands such as National Trust and Ernest Charles as well as an own brand range.
Parent company is Wildlife Habitats, based in Cramlington, Northumberland.
Cherish is supporting UK-based conservation charities including National Trust, BTO and Birdlife International. Cherish is official licensee for National Trust Wild Bird Food.
Managing director Alan Tilmouth said: "Feeding birds in our gardens is a great way of helping support birds locally but we know that in order to conserve birds on a national and global scale we need to support organisations such as Birdlife, National Trust and the BTO.
"By ensuring that a minimum of five per cent of all our sales goes to conservation at the same time as providing competitive prices and a strong quality offer in the bird food market we hope we can help these charities carry out their work to protect habitats, research declines and prevent extinctions."
