Series four of the UK version of Hell's Kitchen began on 13 April 2009^[1] and finished on 27 April 2009.

Angus Deayton did not return to present the show. The reason given for Deayton's dismissal was because he was involved in a series of disputes with head chef Marco Pierre White.^[2] Pierre White has discussed the reasons for his disagreements with Deayton, he commented that "His humour was forced, and negative. I would be working hard and he would be making jibes at where I came from and my name".^[3]

In March 2009 Claudia Winkleman, whom Marco Pierre White has described as "naturally funny",^[3] was confirmed as the new host.^[4]

Marco Pierre White returns as Head Chef/teacher for the second series running. He particularly stated in the first episode that he was "the only chef to return".
