The overall look should be fine if you're not going to be wearing a tie. Crewneck jumper should go well with a button-down collar sans tie. Not sure if you're proposing to buy those exact items, but you can probably spend less than 85 GBP on a shirt and 100 GBP on a jumper and get similar or better quality (e.g. at Yoox). If you're on a budget, Uniqlo is pretty decent for the price. Spend the money that you save on decent shoes. Good luck!
