Rob started performing stand-up in 2009 and quickly enjoyed success in all of the new comedian competitions winning four competitions in his first year. Consistently impressive performances in these competitions, culminated in Rob finishing as a runner up in So You Think You're Funny and winning the Amused Moose Laugh-Off which earned him an invite to perform at Comedy festivals in Australia. At this festival in Adelaide Rob was nominated for the best newcomer award. He made his debut at the Edinburgh Fringe Festival in 2012 with his solo show Rob Beckett's Summer Holiday.
In 2011, Beckett made a guest appearance as Mike in the Channel 4 TV series Fresh Meat. Since 2012, Beckett has co-hosted I'm a Celebrity...Get Me Out of Here! NOW!, the ITV2 spin-off from the main show. In 2012 and 2013 he presented the show with MTV presenter Laura Whitmore and Joe Swash.
On the ninth episode of the seventeenth series of 8 out of 10 cats, Rob demonstrated the ability to peel a banana with his feet.
