    Just leave the 45a in there.  The breaker is there to protect the cable so assuming the circuit is wired with a suitable cable there's no need to change the breaker, whether it's supplying a shower or a cooker is irrelevant.

    6.00mm cable will be ok with the 45a breaker provided the cable isn't going to be buried in insulation. Your oven  will only be drawing 24a at the most.

    Only if there's a socket involved and/or the cable is buried Col !
