Why have I received a Notice of Enforcement from CDER?
The DART Charge is the payment scheme in operation at the Dartford Crossing. You must pay the charge by midnight the day after making your crossing to avoid a penalty charge.
The CDER Group recovers unpaid Penalty Charge Notices (PCN) for Highways England, relating to DART Charge contraventions.
You will have received a PCN from Highways England for an unpaid DART Charge.
As they did not receive payment within the required timescales, Highways England registered the Penalty Charge Notice as a debt at the Traffic Enforcement Centre (TEC), who will have sent you an Order of Recovery.
You will have had 21 days to challenge or pay the Order of Recovery, following which the debt has been passed to CDER through a Warrant of Control. This warrant legally authorises us to undertake enforcement action to recover the outstanding debt.
You will not automatically receive a copy of the warrant, but you can request one directly from us.

What should I do now?
Stage 1: Compliance
Having received the Warrant of Control, we have issued you a Notice of Enforcement for the total amount outstanding, including an additional £75* compliance fee.
You must either pay the total amount or set up a payment arrangement with us to avoid further enforcement action.
What happens if I do not pay during compliance?
Stage 2: Enforcement
If you ignore the Notice of Enforcement, we may send an enforcement agent to your property to recover the outstanding debt.
A £235* fee will be added to the amount outstanding, and if the agent is forced to remove goods to settle the debt, we may add further fees.
All enforcement agents acting on our behalf are certificated in a County Court and operate
in accordance with strict governing legislation and Transport for London's detailed contract requirements and policies.
*The government sets the fees we charge. For more information about Enforcement, please see FAQ page about enforcement.

FAQs for DART Charge Customers
Dart Charge is the payment scheme in operation at the Dartford Crossing.
You no longer pay the crossing charge at the barriers when you cross. Instead, you must pay by midnight the day after making your crossing by one of the following methods:
- online at www.gov.uk/dart-charge
- over the phone by calling: 0300 300 0120
- via a Payzone retail outlet
- by post (in advance only): Dart Charge Customer Services PO Box 842 Leeds LS1 9QF
You can also pay up to a year in advance.
If you only use the Dartford Crossing occasionally, you can register a credit/debit card for automatic payments when your vehicle crosses.
For regular users, a pre-pay account is the cheapest and easiest way to pay. It saves you the hassle of paying each time, and you can set up automatic top-ups. You can add multiple vehicles to your account. Residents need a pre-pay account to access the local residents' discount scheme.
Go to Dart Charge to set up a new account, manage your account or pay for a crossing.
Using the crossing between 10 pm and 6 am is still free.
Dart Charge Penalties
Enforcing the charge is an integral part of the Dart Charge scheme. National Highways use penalty charges and recovery processes to tackle those who do not pay.
Automatic number plate recognition cameras and electronic tags record details of all vehicles using the crossing. These are checked against DVLA records to ensure the correct charge is applied. If you have a pre-pay account, National Highways will withdraw payment. If not, payments are checked to find a match.
If a crossing charge is unpaid by midnight the day after a crossing, National Highways will issue a Penalty Charge Notice (PCN). Find out more at charges and fines.
You must pay the correct charge each time you travel across the Dartford Crossing in both directions so that you may have paid for a different journey.
If you believe we have contacted you about a Dart Charge penalty that you have already paid, please provide evidence of your payment as soon as possible so we can stop further action.
We will need a copy of the receipt from National Highways showing the amount paid, payment reference and date of payment. You should also include any supporting information (payment method, to whom and where payment was made) that will help us resolve the matter quickly.
If the crossing was paid via a pre-pay Dart Charge account, you must provide us with evidence of the account, including account number, name and address, and proof that the particular crossing was taken from the account.
You should send your evidence, including your CDER Group case reference, name and address, to
Email: dartchargecc@contactcder.co.uk
or
Post: CDER Group, PO Box 58, Darlington, DL1 9AE
We may need to contact you further if the information provided is insufficient to confirm that the payment relates to this penalty charge. Until we receive all the evidence needed we are required to continue recovery action.
Before issuing the unpaid penalty charge to CDER Group to collect on their behalf, National Highways will have sent several letters and notices to the address they hold for you. This address is generally the one you have given the DVLA as the vehicle's registered keeper.
If they have received no reply to their correspondence by the due dates, they will have applied to the Traffic Enforcement Centre (TEC) to register the penalty as a debt and sent an Order for Recovery to you.
If you have not received this correspondence and wish to appeal the penalty charge, you must contact the Traffic Enforcement Centre (TEC) using an 'out of time' form to explain why you're making a late challenge.
You can ask for more time to challenge a court order ('order for recovery') if you:
- were contacted about a penalty charge notice (PCN) you didn't know about
- were contacted about a paid or cancelled PCN
- didn't get a response to your formal challenge ('representation') or appeal
Once you have submitted your completed form to the TEC, you should contact us, providing evidence of the confirmation/acknowledgement email from the TEC, so we can temporarily suspend action on your case until the TEC and Transport for London have considered your request.
For more information about submitting an 'out of time' form, please refer to the GOV.UK website or contact the TEC helpdesk on 0300 123 1059.
If you have made a previous appeal ('representation') contesting this penalty charge but have yet to receive a reply, you must contact the Traffic Enforcement Centre (TEC) using an 'out of time' form to explain why you're making a late challenge.
You can ask for more time to challenge a court order ('order for recovery') if you:
- were contacted about a penalty charge notice (PCN) you didn't know about
- were contacted about a paid or cancelled PCN
- didn't get a response to your formal challenge ('representation') or appeal
Once you have submitted your completed form to the TEC, you should contact us, providing evidence of the application, so we can temporarily suspend action on your case until the TEC and Highways England have considered your request.
Some vehicles are exempt from paying for the crossing.
You do not need to pay if you're driving a vehicle that is exempt from vehicle tax because you are disabled. Your vehicle will be checked automatically when you cross – you do not need to do anything.
The complete list of exemptions is described in legislation.
If you received a letter from us about a penalty notice from National Highways and believe your vehicle is exempt from the Dart Charge, you can contact us by emailing dartchargecc@contactcder.co.uk.
You will need to provide us with evidence that your vehicle is exempt.
Please do not ignore our correspondence; it will not go away. If you have received a Notice of a debt you do not believe you owe, you may need to submit evidence or information to stop enforcement action. We appreciate that this may seem like an inconvenience, but we are required to continue to act to recover the debt until we receive the evidence, so it is important that you do this as soon as possible.
If you
- are receiving letters for someone who does not live at your address
- sold the vehicle before the date of the contravention.
- are the new owner of the vehicle
- have never owned the vehicle the charge relates to
