If you're providing her address, it should be the foreign address at which she lives. Their mention of a "UK" address is sneaky, there is no requirement under PoFA for the provision of a UK address:
“current address for service” means—
(a)in the case of the keeper, an address which is either—
(i) an address at which documents relating to civil proceedings could properly be served on the person concerned under Civil Procedure Rules; or
(ii) the keeper's registered address (if there is one); or
(b)in the case of the driver, an address at which the driver for the time being resides or can conveniently be contacted;
I'd be minded to keep it simple, along the lines of:
Dear Sirs,
The name of the driver is [NAME], their current address for service is [FOREIGN ADDRESS].
I will not be providing you or your client with a copy of the driver's driving licence, nor insurance details. As you will be aware, Schedule 4 of the Protection of Freedoms Act does not require the provision of any such documents to transfer liability.
As your client, the alleged creditor, now knows the name and a current address for service for the driver, they no longer have the right to recover any unpaid parking charges from me as the keeper of the vehicle (if such a right existed in the first place, which is denied).
I look forward to your confirmation that your client will no longer be pursuing me in respect of these charges.
Yours
