How to Appeal a Speeding Fine UK 2026
Receiving a speeding fine is stressful, but not every notice results in points on your licence. UK speeding law has strict procedural requirements, and if the police or camera partnership fail to follow them, your case can be thrown out entirely. This guide walks you through the process from receiving a NIP to writing a formal appeal.

When a speed camera or police officer records a vehicle exceeding the speed limit, the registered keeper is sent a Notice of Intended Prosecution (NIP). This notice, required under section 1 of the Road Traffic Offenders Act 1988, must arrive within 14 days of the alleged offence. If it does not, prosecution cannot lawfully proceed. Alongside the NIP comes a section 172 notice requiring the keeper to identify who was driving at the time.
Step 1: Check the NIP arrived within 14 days
The single strongest defence in speeding cases is NIP timing. The law is clear: the NIP must be served within 14 days of the alleged offence. If you received the NIP on day 15 or later, this is a complete defence. Keep the envelope as evidence of the postal delivery date.
Step 2: Respond to the section 172 notice
Even if you plan to appeal the speeding allegation, you must respond to the s.172 notice identifying the driver. Failure to respond within 28 days is a separate criminal offence under s.172 Road Traffic Act 1988, carrying 6 penalty points and a fine of up to £1,000. You can identify the driver and still challenge the speeding offence itself.
Step 3: Decide whether to accept the fixed penalty or request a hearing
A standard speeding fixed penalty is 3 points and a £100 fine. You may also be offered a speed awareness course if eligible. If you believe you have grounds to challenge the allegation, you can request a court hearing instead of accepting the penalty. This is where a well-structured appeal letter makes the difference.
Step 4: Gather your evidence
Depending on your grounds, evidence might include photographs of missing or obscured speed limit signs, dashcam footage, the NIP envelope with postmark showing late delivery, records proving you were not the driver, or evidence that the speed camera was faulty or uncalibrated.
Step 5: Write a formal appeal letter
A formal speeding fine appeal letter should cite the relevant sections of the Road Traffic Offenders Act 1988, state your defence grounds clearly, reference your evidence, and request that prosecution be discontinued. The tone should be professional and factual.
Common grounds for challenging a speeding fine
- NIP not served within 14 days (s.1 RTOA 1988)
- You were not the driver
- Speed camera not calibrated or type-approved
- Speed limit signs missing, obscured, or non-compliant
- Emergency circumstances
- Speed reading inaccurate (GPS evidence, dashcam)
What happens at court?
If you request a hearing, the case goes to Magistrates' Court. The prosecution must prove beyond reasonable doubt that you were driving, that the speed limit was in force, and that the speed measurement is reliable. Any procedural failure weakens their case significantly. Many cases are dropped before reaching court once a strong defence is submitted.
