Having been an analyst for Channel 4’s coverage in recent years, Chandhok has elected to return to Sky – where he was a part of the team from 2012 to 2014.
Speaking about his new appointment, Chandhok said: “I’m very excited to be rejoining the Sky Sports F1 team from the 2019 season.
“With their long-term commitment to Formula 1 and the team of people that’s in place, it’s a great time to return.
“I believe that I’ve been able to develop and offer viewers a unique perspective of someone with a technical, strategic and historical knowledge of the sport combined with the experience of 18 years of driving racing cars.”
Chandhok’s signing comes shortly after Sky, which will broadcast all races apart from the British GP exclusively live in the UK, announced that former world champion Jenson Button was likewise joining it for 2019.
Sky’s line-up of former drivers for 2019 also includes Martin Brundle, Damon Hill, Paul di Resta, Anthony Davidson, Johnny Herbert and Nico Rosberg.
