Check the order again, Fibre 2 can still be FTTP. It will be described as Full Fibre 2.
It was described as Broadband Fibre 2 74/20 DL/UL respectively.
Those speeds certainly sound like FTTC/VDSL. Are you sure full fibre (fttp) is available? This site will tell you

Checker says. WBC FTTP available.
Then if you renew, ADSL will no longer be an option.
I have no idea why anybody would want to stay on ADSL if FTTP is available.
