The actor, who plays Rob Grayson in the BBC One soap, has received criticism for his Burnley accent after fans struggled to understand him.
According to The People, one viewer said on Twitter: "He is TOO northern. I wish he'd tone it down."
Latham, who also played Lip Gallagher in Channel 4's Shameless, said: "I'm sorry people are having difficulty with my accent. I'm sure the great fans of EastEnders will get used to it!"
He joined the show last month as part of Whitney Dean's (Shona McGarty) sex exploitation storyline.
