You’ll also forfeit your good condition bonus, and you’ll not get the advance payment, whatever it is now called.
I swapped cars early three months ago and it was painless. I guess as @kezo says, you’ll pay £250 or maybe just £50 to break out of the contract. I paid £50 and it was my first time cancelling a contract.
Fingers crossed you’ll get the same treatment (or better?).
