If you have a good relationship with the place you bought it from, ask them to change the tap tails to these:
Buy a Tail for tap HOT - 12mm male end | Whale taps | Leisureshopdirect

or just buy a replacement set , they do them for hot and cold and should screw in to the tap, if the ones on your new tap unscrew, and you would need 2 x 12mm John Guest straight connectors.
