The 41-year-old will now step into a new position with the ITV national news team.
Beresford was quoted as saying: “It’s been over a decade since I've been working across the region and it's been the most amazing time.
"It's been a special part of my life and I'm going to miss it."
The TV star said that he was "a Bristol boy through and through".
“The West Country is an amazing place to work," he went on.
"I'd never been to Cornwall before I started working at ITV West Country and I got to explore one of the best parts of the world in my opinion."
Beresford got started as a teleprompter operator back in 2004 but went on to train as a weather presenter the following year.
The star was in the headlines last year when he and former GMB star Piers Morgan had some strong words amid the Meghan Markle row, with Beresford accusing Morgan of “trashing” the duchess.
Morgan ended up quitting the programme after their clash.
