On joining Plymouth Argyle, Hartley quoted on the move,"I spoke to the manager a couple of weeks ago now and I was taken in by his desire to want to go places with this club. When he said he wanted me to jump on board, I couldn't wait. I understand the manager loves his football and is very passionate, so it'll suit me right down to the ground." Hartley was also given the number 29 shirt, just like he wore at Hartlepool United and Stevenage.

After this, Hartley said about the club's relegation, quoting: "Some people might want to say 'it's gone, forget about it' – but we can use relegation as a motivation. I think you can look back to it and remember how we felt when we were relegated. It was horrible and something I don't want to experience ever again. You can use that to make sure it doesn't happen again. It can give you that fire in your belly. That's what we have to do, not just bury it and never talk about it." Ahead of the 2013–14 season, Hartley remained wearing number the twenty-nine shirt until his departure to Stevenage.

In August 2013, Hartley signed for League One side Stevenage for an "undisclosed five-figure sum". On joining Stevenage and leaving his hometown club after four years, Hartley stated – "I'm really looking forward to it. It's a great challenge. I have played against Graham's teams in the past and they are always strong and tough to play against. Sometimes you have to think about what you want out of your career. I'm a hungry and ambitious person. This is a new challenge – it's a new set of lads, a new manager, a new town and new ambitions, it's what I need. I think I need this new start to improve again and I'm excited by it".

Hartley made his Stevenage debut on 17 August, playing the whole match in a 1–0 home defeat to Leyton Orient.
