The electrical goods manufacturer, which spends around £2m on UK advertising, kicked off the review in November.
It had previously worked with agencies on a project basis. JWT London will work across Kenwood’s food preparation portfolio, which includes the sub-brands Chef and kMix.
James Whitehead, the executive partner at JWT London, said: "We look forward to working with such an iconic brand and delivering work that will step-change the Kenwood business."
The media account, handled by MediaCom, is not affected by the review.
