Reply with the following;
PCN Number -
Registration Mark -
To whom it may concern,
I am the Registered Keeper of the above vehicle.
I write in relation to the above parking charge.
The vehicle driver is not known to you and there is no obligation in law for me to reveal the driver details and I will not be doing so.
Your PCN is clearly not relying on PoFA in order to invoke 'keeper liability'.
Your choices are therefore;
1. Cancel this PCN
OR
2. Waste more time, money and resources by rejecting my appeal and supplying me with a POPLA code.
I am sorry that I cannot help you further.
Best wishes,
xxxxx xxxxxxxx
