Aston, who has played fan favourite Chesney Brown since 2003, appeared on This Morning and confessed the 12 month contracts on Coronation Street do give him stress.
He said: "I worry about it every year, 100%. I’ve had that thought more so as an adult because I have more responsibilities now.
"I have two children and I’ve got a mortgage. People say to me ‘you are part of the furniture, you’ll be here for ever’ but I don’t see it like that. I just take it one year at a time."
Aston added that he never stops feeling grateful to be a part of the long-running soap: "I’m lucky to be here. I’ve never taken it for granted or rested on my laurels. No character is bigger than the show, so I’m always very grateful when I get that call asking me to stay."
Aston joined the show in 2003 at just aged nine as the son of Cilla Battersby and sister of Fiz with his character since going on to survive a stabbing, leave his fiance at the alter on their wedding day and become a father a five.
Away from the soap, Aston has two children of his own with wife Briony who he originally met at a drama workshop when they were both 14. After becoming engaged in 2017, they married in 2019 with several Coronation Street stars present.
Despite having been on the show for 20 years, Aston is still not one of the longest tenured actors on Coronation Street. William Roache has played Ken Barlow constantly since 1960 while Barbara Knox and Chris Gascoyne both made their first appearances on the soap in the same decade.
