I tried looking in halfords, and they didn't quote the size in their book for any fabia. The online sellers I looked at dont' quote a size. I assume it is just a standard wiper blade; if so, what size do I need to get (if it matters it is for a vRS)?

thanks in advance.

I think you will find its a custom fit blade. Only seen genuine ones but they aint pricey.

Yeah, they're only available from skoda dealers, but they're about £3.

Get one from a dealer.

They won't bite.....
