The actor, who plays vicar Ashley Thomas, said he has been approached several times about embarking on a political career.
Speaking at the launch of Labour's election campaign in Leeds, he told the Yorkshire Evening Post: "I have been asked to think about it many times but every time I have been in the middle of an Emmerdale contract."
He went on: "I do love my job now - who wouldn't - but I'd never say never.
"My mum and dad were both party members and even as a child I remember running between polling stations and committee rooms with numbers. You could definitely say it is in my blood."
The actor has recently been involved in a dramatic storyline which saw him get drugged by obsessed psycho Sally Spode (Sian Reeves).
