Ouch. Bit of bad luck there!
Good news is the front grill is available separately for a smidge under £67. I can't give you the part number as there are a few listed so best asking the dealer.
Is it the mis fueling insert that's broken? Can't tell from the pics. If so, two parts are listed, one is just under 9 quid, the other 25 quid.
Not idea how much effort is involved in changing all of these but at least the parts aren't mega money.
