Hi Dx, thanks for replying with the link...
It seems the main advice on that thread is this from Cardiff Devil :
If anything does arrive from them, all you need to do is just respond to them stating that the POFA does not apply in this case,
and that you are not liable as the vehicle's registered keeper.
End the letter by politely suggesting that they need to take the matter up with the driver concerned, and leave it at that.
My concern is that I'm slightly different from that poster as I have already sent an appeal to VCS
and they now wont accept any further correspondence,
my only option is to appeal to IAS.
I apologise if I'm being slow on the uptake with all of this,
just that when it comes to IAS I'm not sure what my best option is.
