Pick the situation that matches your charge.

For charges issued on land regulated by byelaws, such as airports, ports and ferry terminals, where POFA 2012 Schedule 4 does not apply, so the operator cannot transfer liability from the driver to the registered keeper. Not for National Rail station car parks: since 26 December 2025 Schedule 4 applies there. Secondary ground: no valid contract formed. Tertiary ground: no landowner authority proved.

For charges based on inaccurate ANPR data. Covers double-dipping (two visits recorded as one), timestamp errors, and plate misreads. Includes specific evidence request for the full ANPR log and camera calibration records.

For charges that bear no reasonable relationship to any loss or legitimate commercial interest. Applies the Beavis two-stage test (legitimate interest + not extravagant and unconscionable) and the Consumer Rights Act 2015 unfair terms provisions.

For charges issued within 10 minutes of the permitted period ending. Both BPA and IPC Codes of Practice impose a mandatory minimum 10-minute grace period at exit. A charge issued within this window is premature and unenforceable.

For cases where the registered keeper was not driving the vehicle at the time of the alleged contravention. Challenges the operator's right to pursue the keeper, includes an optional ground for where you were not even the keeper at the time (car lent out, sold but not yet re-registered, the paragraph 2(1) presumption is rebuttable), and confirms there is no civil obligation to identify the driver to a private parking company.

For charges issued because a vehicle registration was entered incorrectly at an in-store terminal or a payment machine, where the driver genuinely used the site and attempted to enter it correctly. One letter covers both a minor keying error (must be cancelled outright under the Code) and a major keying error (capped at no more than £20), so the customer does not have to self-diagnose which applies. Requires the operator to check its own records for a near-match, not only an exact one, citing POPLA's published case studies on keying errors.

For a private parking Notice to Keeper that arrived late, or that you suspect was posted late. Five components: a date calculator that tells you whether the notice was actually given out of time, the letter that forces the operator to disclose the date of posting, how to evidence when it really arrived, the two points that still work even when the notice was in time, and a plain account of what the ground does and does not achieve. Includes a worked example from a real ParkingEye case that comes out in time, because a calculator that always produces a win is worse than useless.

For cases where the operator cannot demonstrate a valid contract with the landowner. Includes the DVLA KADOE unlawful data processing argument under UK GDPR Article 6(1).

For notices using prohibited terminology (PCN, penalty charge notice, contravention) or missing mandatory content (unique reference, payment details, appeal details, AOS logo). Applies BPA and IPC Code of Practice requirements for notice format.

For charges issued despite a valid parking session having been paid for, whether at the machine or through an app such as RingGo, PayByPhone or JustPark. Puts your proof of payment front and centre, establishes that no breach of contract occurred, and requires the operator to produce its own payment and ANPR records if it maintains the charge. Includes an optional ground for camera-triggered charges where the operator's systems failed to reconcile a payment that was actually made.

For notices missing one or more of the mandatory prescribed statements under Schedule 4 paragraph 9(2). Covers: missing entry/exit times, absent keeper liability statement, no driver identification invitation, inadequate response period.

For camera-only enforcement where the Notice to Keeper was served too early or too late. Cites Protection of Freedoms Act 2012 Schedule 4 paragraphs 8(4)-(5), 9(4)-(5). The single most decisive ground available against keeper liability.

First-stage challenge citing POFA 2012 Schedule 4 keeper liability, signage non-compliance (BPA/IPC Code of Practice), landowner authority, and Consumer Rights Act 2015 proportionality. Cites ParkingEye v Beavis [2015] UKSC 67.

For sites where signs were absent, obscured, non-compliant with the Code of Practice, or failed to clearly state the charge before commitment to park. Cites the Beavis test for signage adequacy.

For parking charges issued at a car park on one of four transport networks: London Underground, London Overground, DLR, Elizabeth line and Croydon Tramlink (Transport for London and Tramlink land); Tyne and Wear Metro (Nexus land); and Nottingham Express Transit, including its Park and Ride sites. Parking on all four is regulated by byelaws that impose both criminal and civil liability, so the land is not "relevant land" and the operator cannot transfer liability from the driver to the registered keeper. Quotes the applicable byelaws by number, and answers both December 2025 Orders head on: SI 2025/1256, which put National Rail station car parks back inside keeper liability, reaches only the Strategic Rail Authority byelaws, and SI 2025/1258, which removed the parking charge liability from those byelaws, amends only those same byelaws. Neither touches the byelaws applying here. Secondary ground: no valid contract formed. Tertiary ground: no landowner authority proved. Not for National Rail stations, and it defeats keeper liability only, not a claim against an identified driver.

Complete challenge letter for TfL bus lane Penalty Charge Notices. Covers: TSRGD 2016 signage/marking non-compliance, outside hours of restriction, exempt vehicle class (black taxi, motorcycle, emergency), CCTV evidence insufficiency and observation period (SI 2022/71), TRO mismatch (RTRA 1984), and contravention did not occur (brief incursion vs deliberate use).

Complete challenge letter for Congestion Charge Penalty Charge Notices. Covers: payment made, vehicle exempt (ULEZ-compliant/EV, black taxi, NHS, disabled, resident discount), vehicle not in zone, ANPR misread, technical payment failure, Auto Pay. Cites Greater London Authority Act 1999 and Congestion Charge Scheme Order.

For a moving traffic Penalty Charge Notice in Greater London: a yellow box junction, a banned turn or another failure to comply with a sign, prefix GT on a TfL notice. Pleaded on the London Local Authorities and Transport for London Act 2003, which is the correct Act inside London and is expressly outside the 2022 England Regulations. Leads on the box junction prohibition as it is actually written, which bites only where the vehicle had to stop because of stationary vehicles, and on the right turn exception that most drivers never learn exists. Includes the maintenance duty on the authority to keep signs in place, and mirrors the five grounds the authority itself publishes so the representation is read against the right list.

Complete challenge letter for TfL red route Penalty Charge Notices. Covers: TSRGD 2016 signs/markings non-compliance, TRO mismatch (RTRA 1984), boarding/alighting exemption, loading exemption (single red line only), breakdown/emergency, outside hours, CCTV evidence insufficiency (SI 2022/71), observation period inadequacy, and contravention did not occur.

For an appeal after TfL has rejected your representations. Built around the question that decides most appeals, which is not what you argued but what TfL failed to answer. Leads with the late appeal power at regulation 16(1A), under which an adjudicator may extend the 28 day period whether or not it has already expired, a provision almost nobody uses. Narrows the case to one disputed question, indexes the evidence, and sets out plainly what the adjudicator can and cannot do so that mitigation is kept out of it.

Complete challenge letter for ULEZ Penalty Charge Notices, pleaded on the six statutory grounds at regulation 13(3) of the Road User Charging (Enforcement and Adjudication) (London) Regulations 2001. Covers compliance error (TfL record against Certificate of Conformity), non chargeable vehicles including the disabled tax class grace period, charge paid, vehicle not in the zone or misread, and Auto Pay. Separates the statutory grounds from a discretion request, because an adjudicator cannot cancel on a genuine mistake alone.

For a ULEZ PCN where the charge was paid correctly and a penalty was issued anyway. Pleaded on regulation 13(3)(b). Sets the transaction out as a reconciliation TfL can match against its own records, which is far stronger than asserting that you paid, and covers Auto Pay where the vehicle was genuinely attached to an active account. Warns clearly that a payment made for the wrong registration or the wrong day is a different letter.

For a ULEZ PCN issued because another vehicle was displaying your registration mark. Pleaded on regulation 13(3)(c). Includes the feature by feature comparison sheet TfL needs in order to accept a cloning case, the evidence order to follow, the police crime reference step, and a direct answer to the make and model match point that TfL leads with.

The complete evidence pack for a ULEZ PCN caused by someone else using your registration mark. Six components: the day by day sequence, because the order decides the case, the camera image request to send on day one, a photography protocol for matching TfL angles and proving the date, the feature by feature comparison sheet and representation, a record keeping sheet for the chronology, and the appeal keyed to whichever difference TfL failed to answer. Includes the police crime reference step TfL asks for.

For a ULEZ PCN where the vehicle is registered with the DVLA in the disabled or disabled passenger vehicle tax class, which carries a grace period to 24 October 2027. Pleaded on regulation 13(3)(c). Opens by making you check the V5C, because the entitlement attaches to the vehicle's tax class and NOT to receiving PIP, DLA or Attendance Allowance. That is the most common and most expensive misunderstanding about ULEZ and several websites state it wrongly.

For a vehicle hire firm transferring liability for a ULEZ PCN to the hirer. Pleaded on regulation 13(3)(f). Opens with a six point document checklist to run before sending, because this ground is a documents test rather than an argument, and the signed statement of liability is the element most often missing.

For a ULEZ or LEZ penalty demanded from an overseas registered vehicle or operator, where the sum demanded is in another currency, has an exchange rate applied to it, or carries an administration or collection fee. Pleaded on regulation 13(3)(e), the penalty exceeding the amount applicable, and anchored on regulation 5 of the 2001 Charges Regulations, under which the rates of penalty charges must be specified in the charging scheme. That makes the scheme the only source of the lawful amount, so anything above it is outside it. Also covers service on an address outside the United Kingdom, and separates the ULEZ figures from the very different LEZ figures for vehicles over 3.5 tonnes.

For a ULEZ PCN where you paid but entered the wrong registration or the wrong date, or Auto Pay failed. This is deliberately NOT pleaded as a statutory ground, because it is not one: in Walmsley v TfL [2005] EWCA Civ 1540 the Court of Appeal held an adjudicator cannot cancel on a genuine mistake, on almost identical facts. It is a request to TfL, which the same judgment confirms holds that power, and it asks TfL to say which part of its discretion policy it applied. Includes the Dolatabadi limb where TfL gave you information you relied on.

For a ULEZ penalty that has reached a county court order after a charge certificate. This is the statutory declaration route under regulation 19, available on three grounds only: you did not receive the PCN, you made representations and received no rejection, or you appealed and received no response. Time limit 21 days from service of notice of the order. Carries a prominent warning that a false declaration is a criminal offence, and explains that success on the first ground revokes the order and cancels the charge certificate but allows TfL to serve a fresh PCN, which is your chance to make representations properly.

For a ULEZ PCN where the vehicle actually meets the emissions standard but TfL records it as non compliant. Pleaded on regulation 13(3)(c), no penalty charge payable. Identifies the vehicle by VIN, sets the applicable Euro standard against the figure the vehicle achieves, structures the manufacturer evidence as numbered exhibits, and answers the two rejections TfL gives most often: that its records show non compliance, and that DVLA data does not confirm compliance.

The complete evidence pack for a ULEZ PCN where the vehicle actually meets the standard. Six components: a decision sheet establishing which standard applies to your class, a Certificate of Conformity request script and who to send it to, an exhibit index, the representation itself pleaded on regulation 13(3)(c), the two rejections TfL sends and how to answer each, and the appeal to the Road User Charging Adjudicators. Built because TfL has said appeals are commonly not contested once better evidence arrives late. This gets it in first time.

For a ULEZ PCN where the vehicle was taken or used by someone in control of it without your consent. Pleaded on regulation 13(3)(d). Opens with an honesty gate, because a family member who already had permission is not unauthorised use and pleading it as such damages the rest of the case. Structures the timeline and the police and insurance evidence the ground needs.

For a ULEZ PCN sent to the wrong person: you never were the keeper, you sold the vehicle before that date, or you bought it after. Pleaded on regulation 13(3)(a). Includes the requirement most DIY letters miss, that representations on this ground must state the name and address of the person the vehicle was disposed of to or acquired from so far as you hold it, and answers the two responses TfL gives most often about the DVLA record.

Post-Notice to Owner stage. More detailed than informal representations. Specifically addresses the authority's rejection, expands evidence, and formally preserves the right to appeal to the Traffic Penalty Tribunal or London Tribunals.

First-stage challenge under TMA 2004. Grounds: contravention did not occur, signage non-compliance with TSRGD 2016, TRO mismatch (Road Traffic Regulation Act 1984), procedural impropriety (Civil Enforcement Regulations 2022, SI 2022/71), and statutory exemptions.

For a Clean Air Zone penalty outside London where the authority has rejected your representations. Six components: the four checks to run before filing, the out of time application under regulation 11(2), under which an adjudicator may allow a late appeal even after the period has expired, the gap analysis that decides most appeals, an evidence index, the appeal itself, and the fallback almost nobody uses. That last one is regulation 11(9): even where the appeal fails, the adjudicator may recommend cancellation for compelling reasons, and the authority then has a duty to reconsider and to answer within 35 days with reasons if it refuses. There is no equivalent of that in London.

For a Clean Air Zone PCN outside London where the charge was paid correctly and a penalty was issued anyway. Pleaded on regulation 8(3)(d). Sets the transaction out as a reconciliation the authority can match against its own records rather than a bare assertion that you paid, and warns clearly that a payment made for the wrong plate or the wrong day is not this ground.

For a Clean Air Zone penalty outside London where you have no clear statutory ground, or a thin one, but something genuinely unusual about your circumstances. This is not a plea for sympathy. Regulation 9(1) of the 2013 Regulations requires the authority to cancel, and to refund, where it accepts that there are compelling reasons why in the particular circumstances the penalty should be cancelled. That is a statutory test and a duty, not a favour, and there is no equivalent in London. The letter frames the circumstances against that test, keeps it in the alternative where you also have a ground, and explains that the identical test is available again from an independent adjudicator under regulation 11(9) if the authority refuses.

For a vehicle hire firm transferring liability for a Clean Air Zone PCN to the hirer. Pleaded on regulation 8(3)(c), read with regulation 6(5). Opens with a six point document checklist to run before sending, because this ground is a documents test rather than an argument and a missing signed statement of liability defeats it outright.

For a Clean Air Zone PCN where the authority says your challenge was out of time, or where you are close to the deadline. Built on regulation 3, which deems service a set number of working days after posting rather than on the date printed on the notice. Includes the change made by SI 2026/752 from 7 September 2026, under which non first class post to a UK address is deemed served on the fourth working day rather than the second, which moves the deadline in the motorist’s favour. Puts the authority to proof on the date and class of posting.

For a Clean Air Zone PCN outside London where the amount demanded is wrong for the stage you are at. Pleaded on regulation 8(3)(f). Covers a discount withdrawn too early, escalation before the relevant period expired, the wrong rate for the vehicle class, and multiple penalties for a single cause. Sets out the calculation and puts the authority to proof of the provision it relies on.

For a Clean Air Zone PCN outside London where the authority has not followed the procedure the rules require. Pleaded on regulation 8(3)(g) of the 2013 Regulations, a ground that does not exist in the London ULEZ at all, so most letters circulating online do not use it. Covers defective notice content, miscalculated service dates, the charging scheme order and whether it covers your vehicle and location, unanswered earlier correspondence, and route specific signage. Includes an explicit list of what not to argue.

For a Clean Air Zone PCN outside London where the vehicle actually meets the applicable emissions standard but the authority records it as non compliant. Pleaded on regulation 8(3)(e), no charge payable. Identifies the vehicle by VIN, structures the manufacturer evidence as numbered exhibits, and prompts you to check the standard your own zone applies rather than assuming the London figures, because Clean Air Zone classes A to D cover different vehicle types.

For a Clean Air Zone PCN outside London where the vehicle was taken or used by someone in control of it without your consent. Pleaded on regulation 8(3)(b). Opens with an honesty gate, because a family member who already had permission is not unauthorised use and pleading it as such damages the rest of your case. Structures the timeline and the police and insurance evidence the ground needs.

For a Clean Air Zone PCN outside London sent to the wrong person: you never were the keeper, you sold the vehicle before that date, or you bought it after. Pleaded on regulation 8(3)(a). Builds the chronology the authority needs, captures the buyer or seller details, and answers the two responses authorities give most often, that the DVLA record showed you as keeper and that you notified the DVLA late.
