The Manchester City man is looking forward to taking part and dealing with the extra pressure handed to him after spending the 2010 World Cup on the bench
The Manchester City shot-stopper was part of the Three Lions squad for World Cup 2010 but was back-up to Rob Green and David James.
And now as England’s undisputed No.1, Hart is eagerly anticipating the start of the tournament and has no fears about the extra responsibility placed on his shoulders this time around.

"I must have improved in that time [since the World Cup]. I seem to be getting better," Hart told reporters.
"Whether that comes from playing regularly... but I've always felt like I'm improving although I feel like I've got loads more to do.
"South Africa was amazing. I absolutely loved it. I just wish we had done better as a team. We had a really good squad out there and it was unfortunate we couldn't do as well as we wanted to.
"For me, it's a totally different mindset this time to two years ago. There's an awful lot more expected of me this time with playing all the qualifying games and things like that.
"But I like that responsibility and hopefully I'll bring something positive to the team."
England kick-off their campaign next Monday against France, who Hart believes will pose a real threat to Roy Hodgson’s side.
However, the 25-year-old feels the Three Lions' solid displays in their warm-up games will stand them in good stead for the start of the tournament.
He contined: "The game against France will be one of the biggest games of the championships.
"France will play some pretty football around the box so we have to be ready for that.
"Thankfully I've been lucky enough with England to have been involved in some pretty big games the last couple of years and this will be the next one.
"The fact we are looking solid helps. It's something I've had with my club side and it's helped us do well, winning the Premier League and FA Cup.
"That's been mirrored with England. We communicate well and have a solid set-up. The defence has been great."
