Hall told QPR’s official website: Hall said: “Knowing I have got a long-term deal means I can really concentrate on my football. I’m very happy here and I want to progress because my aim is to play for QPR in the Premier League.
“It is a fantastic club and I have a great relationship with the fans. They have really taken to me and helped me a lot, which I really appreciate.
“I came in as a back-up player, but when I have got my chance I have taken it, and I feel I’ve gone from strength to strength.
“I am really confident in the way I am playing and believe I can only get better if I keep doing the right things.”
QPR boss Jimmy Floyd Hasselbaink added: “We’re really pleased Grant has committed his long-term future to the club.
“He’s played a key role since arriving here in the summer, and we expect him to continue to do this. He has impressed everyone here with both his performances and professionalism.
“Whilst he still has a lot to learn and improve upon, we’re pleased he’s agreed an extension to his current deal and we’re looking forward to him playing a pivotal part in our future.
“And being a young British player, Grant fits in with the way we want to move forward.”
