The pronounced ridge that runs along the side of the car (and also through the fuel flap) is catching the fuel flap everytime I open it to refuel. This has developed over time and took me a while to diagnose, as I stand behind the fuel flap when I refuel so that side of the fuel flap isn't in my line of sight, and though it hasn't taken paint off yet, I know it won't be long.

Careful examination when the flap is closed shows the ridge on the flap is slightly out of line with the ridge on the car.

Dealer has attempted to adjust, but said there isn't much adjustment in it, and sure enough the problem returned a week later.

Has anybody else suffered this, and how did you fix it?

Obviously, my plan is to return to the dealer and insist they either have a better attempt at adjusting, or perhaps replace the fuel flap.

The dealer needs to fix it or ring Skoda UK and tell them how dissatisfied you are.

I certainly will. None of the other Fabias at the Dealer shared the problem, but there is such an incredibly fine gap between the ridges on the flap and the surrounding OSR wing (as the flap is opened), that it's probably a problem waiting to happen for other owners as their cars age. A drawback of Škoda's attempt to make the design of their cars' flanks more interesting!
