Ignoring a Penalty Charge Notice can feel easier than dealing with it, especially if you are unsure whether the PCN is fair or you have already missed the discount window. But the longer a PCN is left unanswered, the more likely it is to become more expensive and harder to challenge.
If you are unsure how much time you have left, it helps to first understand the key stages in the PCN deadline guide. Most PCNs follow a timeline that starts with a reduced payment period, moves into the full-charge stage, and can later lead to a Charge Certificate if no action is taken.
This guide explains what happens if you ignore a PCN, what extra costs may be added, and what you can still do if you have missed an important deadline.
Why ignoring a PCN is risky
The biggest risk is that the penalty does not disappear. If you do nothing, the authority can move the case through enforcement stages. That can mean losing the discount, facing a higher charge, and eventually dealing with debt registration or enforcement agents. Traffic Penalty Tribunal guidance warns that an unpaid or ignored PCN can increase and may later be registered as a debt.
Ignoring also reduces your options. Early on, you may be able to explain what happened, upload evidence, or make an informal challenge. Later, the process becomes more formal and the grounds for responding become narrower.
What happens after the first 14 days?
The first 14 days usually matter because this is the discount period. For many council parking PCNs, paying within this window reduces the penalty by 50%.
If you miss this deadline, it does not always mean you are in immediate trouble, but it often means the discounted amount is gone. You may now need to pay the full penalty unless the authority accepts a challenge or re-offers the discount after considering your case.
What happens after 28 days?
After 28 days, the PCN may move to the next enforcement stage. In many cases, if the PCN has not been paid or challenged, the authority can issue further notices. London Tribunals explains that a Charge Certificate may be issued when payment has not been made and no representations or appeal were received within the required 28-day period.
This is why the 28-day deadline is so important. It is often the point where the issue changes from “pay or challenge” to “you have missed the normal response window.”
What is a Charge Certificate?
A Charge Certificate is a formal notice saying the penalty has increased. The increase is usually 50% of the full penalty charge. London Tribunals and Transport for London both describe the Charge Certificate as increasing the penalty by 50% when the PCN has not been paid in time.
Once a Charge Certificate is issued, you are usually given a short period to pay the increased amount. TfL says this stage gives 14 days from the date of service to pay the increased charge.
Can you still challenge after ignoring it?
Possibly, but it depends on the stage. If the case is still within the normal appeal period, you may be able to challenge. If a Charge Certificate has already been issued, the normal appeal route is usually closed.
However, if the case later reaches Order for Recovery, there may be limited legal grounds to file a witness statement or statutory declaration. For example, this may apply if you did not receive an earlier notice or made representations but did not receive a response. The Traffic Penalty Tribunal says you may have 21 days to make an application after receiving the relevant form, depending on the circumstances.
What to do if you already missed the discount
First, do not panic. Missing the discount is frustrating, but it does not always mean the worst outcome has happened.
Check the PCN carefully. Look at the issue date, service date, amount due, deadline, vehicle details, location, and any photos. Then decide whether you should pay, challenge, or seek advice based on the current stage. If you have a genuine reason for delay, include clear evidence, such as photos, payment records, medical evidence, delivery proof, or screenshots.
Avoid making guesses. The best next step depends on whether you are at the discount stage, full-charge stage, Charge Certificate stage, or debt recovery stage.
