The actor - best known for playing DI Neil Manson in The Bill - will make his first appearance on the cobbles early next year when Frank is introduced as one of Carla Connor's (Alison King) business associates.
According to the ITV soap's official website, Frank goes on to become a new factory client before pursuing Carla's right hand woman Michelle (Kym Marsh) as he looks for love.
Speaking of his new part, Lancel commented: "I'm made up to be here. It's been a long time coming and I'm a big fan of the show so I'm thrilled."
He added: "Frank looks like he's going to be fun to play, there's more to him than meets the eye, he's definitely not one-sided."
As well as The Bill, Lancel's screen credits include roles in medical drama Cardiac Arrest, Bad Girls and Queer as Folk.
