ULEZ Fine Appeal Letter Template: How to Challenge Your PCN

How the ULEZ PCN Appeal Process Works

TfL issues ULEZ PCNs under civil enforcement powers. The process has two main stages before you reach an independent adjudicator. First, you make an informal challenge within 14 days of the PCN date to keep the discounted penalty (50% of the full amount). TfL will either accept it and cancel the charge, or reject it and issue a Notice to Owner.

Once you receive the Notice to Owner you have 28 days to make formal representations. TfL then issues a Notice of Rejection or accepts your appeal. If rejected, you have 28 days to appeal to London Tribunals, which is entirely independent of TfL. Missing any of these deadlines seriously limits your options, so act quickly.

Paying or Appealing: Which Should You Do First?

If you pay the discounted amount within 14 days you lose the right to appeal, so only pay early if you are certain the charge is valid and you have no grounds to challenge it. If you intend to appeal, submit your informal challenge instead of paying. The discount period is paused while TfL considers a properly submitted challenge.

Never ignore a ULEZ PCN. If you do nothing, the penalty increases by 50% at the charge certificate stage, TfL can then apply for an Order for Recovery, and enforcement action including debt registration follows. An appeal costs you nothing to attempt.

Grounds That Often Succeed in ULEZ Appeals

Your letter must set out a clear legal or factual reason why the charge should be cancelled. Vague dissatisfaction with the ULEZ scheme itself is not a valid ground and will be rejected. Focus on one or more of the following grounds that regularly succeed at the informal and formal stages.

Vehicle exemption or incorrect ULEZ status: your vehicle meets the emission standard but TfL's records are wrong. Military, disabled, or other exempt vehicle categories were misapplied. The PCN was issued in error because ANPR misread the plate. You were not the registered keeper at the time. Procedural errors: the PCN does not contain the required statutory information, signage at the boundary was absent or obscured, or there was a genuine emergency that prevented compliance.

• ▸Vehicle incorrectly recorded as non-compliant by TfL
• ▸ANPR camera misread your number plate
• ▸You were not the registered keeper on the date of the contravention
• ▸Vehicle is exempt (e.g. disabled tax class, military, historic vehicle registered before 1 January 1979)
• ▸Statutory signage missing or inadequate at the ULEZ boundary you crossed
• ▸Medical or other genuine emergency prevented you leaving the zone
• ▸PCN contains a material error (wrong date, location, or vehicle details)

What to Include in Your Appeal Letter

Whether you are writing an informal challenge or formal representations, your letter should follow a clear structure. Open by quoting the PCN reference number, vehicle registration, and the date of the alleged contravention. State plainly that you are challenging the PCN and on what ground. Then set out your evidence and argument in short paragraphs, one point at a time.

Close by asking TfL to cancel the PCN and confirm you will escalate to London Tribunals if they do not. Keep the tone factual and professional. Attach copies of any supporting documents: a V5C showing you were not the keeper, a DVLA printout confirming your vehicle's emission standard, a photograph of missing signage, or a letter from a medical professional if you are relying on emergency grounds.

Sample Letter Structure for a ULEZ Informal Challenge

Use this structure as the basis for your own letter, adapting the ground to your specific situation.

To: TfL Customer Services. Subject: Informal Challenge — PCN Reference [XXXXXXXX]. Dear Sir or Madam, I am writing to challenge Penalty Charge Notice [reference] issued on [date] in respect of vehicle [registration]. I dispute this charge on the following ground: [state your ground clearly, e.g. 'My vehicle is recorded by DVLA as a Euro 6 diesel and therefore complies with the ULEZ emission standard. I enclose a copy of my V5C and a DVLA vehicle enquiry printout confirming this.']. I respectfully request that you cancel this PCN. If you are unable to do so, please issue a Notice to Owner so that I may make formal representations. Yours faithfully, [Your name, address, contact details].

Escalating to London Tribunals

If TfL rejects your formal representations, you can appeal to London Tribunals, an independent body that adjudicates on all London PCNs including ULEZ. The adjudicator is not employed by TfL and has the power to cancel the PCN entirely. Appeals are often handled on paper, though you can request a hearing.

London Tribunals statistics show a significant proportion of appeals that reach the adjudicator stage are allowed or result in the authority withdrawing the PCN. Submitting a well-evidenced appeal letter at the informal stage can prompt TfL to cancel before you ever need to reach that point.

Common Mistakes to Avoid

Do not simply say the charge is unfair or that you did not know about the ULEZ. Policy disagreement is not an appealable ground. Do not send originals of documents — always send copies. Do not miss the 28-day deadline for formal representations after receiving the Notice to Owner, as late submissions require TfL's permission to accept.

Keep a record of every letter, email, or online submission you make, including the date sent and any reference numbers given. If you submit online via TfL's portal, save or print the confirmation page. If you post a letter, use signed-for delivery.
