OP, a quick skip through relevant law.
You posted: I do not have a copy as it was sent via Euro Car Parks website, I made this appeal the same day I received the letter. In this appeal, I did identify myself as the driver.
So, the NTK is now redundant as far as being a statutory notice but not as regards conveying the particulars of the creditor's claim for which there is no prescribed format as regards a claim against a driver for breach of contract.
Why?
Because a NTK is a creation of Schedule 4 to the Protection of Freedoms Act 2012 whose sole objective is to regulate how creditors may kick into touch the centuries-old legal principle that only the parties to a contract have rights and responsibilities under that contract by allowing the creditor to hold the keeper/hirer liable for breaches in lieu.
You do not fall into this category - because you have identified yourself as the liable party to the contract(AKA the driver) therefore it is a straightforward issue of whether the driver is liable to pay a parking charge to the creditor for breaching the terms of contract by which they were deemed bound by entering and parking on this private land. It is a matter pure and simple of contract law and POPLA's remit.
Of course there is common ground between PoFA and contract law, there's bound to be. But don't be fooled into thinking that aspects which are common fall to be considered under PoFA, they don't.
So, what were the terms of the contract into which you entered, was there a breach etc? These are the issues for POPLA.
But why POPLA you may ask if PoFA doesn't apply?
Because members of the BPA's AOS have signed up to this and the Code of Practice by virtue of their membership.
And as regards bp's assertion that the level of charge is an abuse of process, IMO this is not correct as each case turns on its own facts. However, it could be argued to be but IMO the issue at large is what additional charges if any could a creditor add to their claim while simply pursuing the driver for a breach of contract...the answer to which would require a detailed examination of the terms of that specific contract e.g. their clarity, fairness etc.
Is my view.
