You have every reason to challenge what has occurred, especially given that you paid the debt in full in February and were later told it was reversed without your knowledge. Even if enforcement were lawfully resumed, which remains highly questionable, there are strict procedures that must be followed, including giving you clear notice and not imposing additional fees unless properly justified under the regulations.
Storage fees, for example, cannot simply be added without proof. Under the Taking Control of Goods (Fees) Regulations 2014, enforcement agents may only charge fees that are either fixed or reflect actual costs incurred. If storage is claimed, they must be able to show that they paid for it and that the amount is reasonable. This is not a discretionary fee and cannot be inflated or imposed without proper documentation.
As your next step, you may wish to file an urgent application to the County Court to stop the auction and seek the return of your vehicle. You can explain that the debt was previously paid, no valid notice was given, and the fees now demanded are not supported by law. If you are considering paying the fee under protest to recover your car, make sure you clearly record that the payment is made under objection so that you can later pursue a refund through the appropriate legal process.
If you are also submitting PE2 and PE3 forms to challenge the original PCN, and they are accepted, then yes, if the court cancels the enforcement order, you may be eligible for a refund of enforcement fees already paid. Just be aware that the outcome depends on the tribunal accepting your reasons for filing late.
Stay calm, keep copies of all evidence, and ensure everything you submit to the court or to the Traffic Enforcement Centre is clear, complete, and supported by documentation. If you need help preparing your court application or understanding the legal position in more detail, seek individual advice as soon as possible. Time is now very short before the auction date.
