Dartford Crossing: How to pay the Dart Charge and what to do if you forget

The Dartford Crossing, which includes the Dartford Tunnel (northbound) and the Queen Elizabeth II Bridge (southbound) on the M25, is one of the busiest road crossings in the UK. Around 40–50 million vehicles use it each year. Since 2003, drivers must pay a toll known as the Dart Charge to use the crossing. There are no pay booths on site (these were removed in 2014 to ease congestion), so all payments are made electronically. This guide explains how to pay the Dart Charge, how much it costs, and what to do if you forget to pay, all in a clear, up-to-date way. We’ll also cover tips to avoid fines, how to appeal penalties, and other useful info for using the Dartford Crossing.

Key reminder: You must pay the Dart Charge by midnight the day after you use the crossing (unless you’ve paid in advance). If you don’t pay on time, you’ll receive a fine (Penalty Charge Notice), but don’t worry, we’ll explain how those work and how to avoid them. Read on for everything you need to know to cross the Dartford Crossing smoothly and without any unwelcome surprises.

How Much Does the Dartford Crossing Cost?

The cost of using the Dartford Crossing depends on your vehicle type. As of 2024, the Dart Charge toll for a single crossing (either direction) is:

Dartford Crossing operating hours: The Dart Charge applies every day from 6 am to 10 pm (including weekends and bank holidays). The crossing is free to use overnight between 10 pm and 6 am, so journeys during those hours do not incur any toll.

Local resident discount: Residents of Dartford and Thurrock can get a Local Residents Discount (previously Dart-Tag) for the crossing. Locals can use the crossing an unlimited number of times for £20 a year, or up to 50 crossings a year for £10. This scheme is for people living in specific areas near the crossing, you can apply through the official Dart Charge service to get the discount.

Upcoming price changes: Note that the Dart Charge rates are set to increase from 1 September 2025. For example, the standard car fee will rise to £3.50 (or £2.80 with a pre-pay account), two-axle goods vehicles to £4.20 (£3.60 with account), and HGVs to £8.40 (£7.20 with account). Motorbikes will remain free. These changes aim to manage congestion, as the current charges haven’t changed since 2014. Always check the official Dart Charge website for the latest prices before you travel.

How to Pay the Dart Charge (Dartford Crossing Toll)

There are several convenient ways to pay the Dartford Crossing charge. You can pay in advance (up to 12 months before your trip) or by midnight the day after crossing at the latest. If you’re a frequent user, setting up an account can save you money. Here are the payment methods available:

1. Set Up a Pre-pay Dart Charge Account

A Dart Charge pre-pay account is the cheapest and easiest way to pay if you use the crossing regularly. You put credit in your account and each crossing is then deducted automatically. Benefits of a pre-pay account include a discounted rate for cars (£2.00 instead of £2.50 per crossing) and convenient automatic payment.

Setting up a pre-pay account is easy: visit the official gov.uk Dart Charge website and follow the instructions to create an account. You’ll need your vehicle details and a payment method for top-ups.

2. One-Off Payment Online (Pay As You Go, Without an Account)

If you’re an occasional user or just making a single trip, you can pay the Dart Charge online as a one-off without creating a pre-paid account. This is essentially a “pay as you go” option for individual crossings.

Tip: If you use the one-off online payment, consider setting a reminder or paying as soon as you can on the same day. It’s easy to forget once your journey is over, and missing the deadline will lead to a fine. Paying online is quick and you’ll receive a confirmation email, always save your payment confirmation until you’re sure everything is processed (in case you need proof later).

3. Pay by Phone

You can pay the Dart Charge over the phone, which is handy if you don’t have internet access. Telephone payments are accepted by the official Dart Charge helpline.

4. Pay in Advance (Up to 1 Year Ahead, or with Your Booking)

If you know your travel plans in advance (for example, you’re driving to the airport next month via Dartford Crossing), you can pay ahead of time for peace of mind. Advance payment can be made up to 12 months before your trip for a specific date.

5. Pay at a Payzone Retail Outlet

If you prefer to pay by cash or in person, you can do so at Payzone outlets. Payzone is a network of shops (newsagents, convenience stores, gas stations, etc.) where you can make bill payments, including the Dartford Crossing toll.

6. Pay by Post (Mail a Cheque in Advance)

For those who aren’t fans of electronic payments, there is an option to pay by post using a cheque. This method is only for advance payments, you cannot post a payment after you’ve already crossed, because it wouldn’t arrive in time.

By using any of the methods above, you can settle the Dart Charge and avoid any fines. If you set up an account (pre-pay or pay-as-you-go), the system will handle payments automatically for you. If you choose manual one-off payments, just remember that deadline: midnight the next day after crossing.

Dart Charge FAQs (Frequently Asked Questions)

Still have questions about using the Dartford Crossing and the Dart Charge system? Here are answers to common queries and concerns:

Are any vehicles exempt from the Dart Charge?

Yes, a few categories of vehicles can use the Dartford Crossing without paying the toll. Notably, motorcycles (including mopeds) and bicycles are completely free, they do not have to pay the Dart Charge. Also, certain specialized vehicles and situations are exempt, such as:
Vehicles used by disabled persons that are exempt from vehicle tax (VED) due to disability. If you have a vehicle that’s in the “Disabled” tax class with the DVLA, you won’t have to pay the Dart Charge. (Blue Badge alone doesn’t grant exemption; it’s tied to the vehicle’s tax class, so double-check with the DVLA if you think you qualify.)
Emergency service vehicles and authorities’ vehicles (police, fire engines, ambulances, military vehicles) are exempt when on duty.
Local buses registered in certain categories and some passenger transport services may be exempt.
For most regular drivers, unless your vehicle is specifically exempt by law, you should assume you need to pay the toll. If you believe your vehicle is exempt (for example, due to disability tax status), you can contact the DVLA or Dart Charge support to confirm and ensure your vehicle is registered correctly to avoid mistaken fines.

Is the Dartford Crossing free at night?

Yes. The Dartford Crossing is free to use between 10:00 pm and 6:00 am every day. If you cross during those hours, you do not need to pay the Dart Charge. This nighttime free period applies in both directions and includes all vehicle types.
Many drivers aren’t aware of this, but it can be useful. For instance, if you’re planning a trip and timing is flexible, traveling very early in the morning or late at night could save you the toll fee (and usually you’ll face less traffic too!). Just keep in mind that 6:00 am means from 6 onwards you pay, so if you pass through at 5:50 am, it’s free, but at 6:05 am, you’ll be charged.

Why were the toll booths removed from the crossing?

The old toll booths at Dartford (where drivers stopped to pay cash) were removed in late 2014 when the Dart Charge system was introduced. The official reason was to create a “free-flowing” traffic system to reduce congestion. The stop-and-go of toll plazas was causing big traffic jams on the M25 approach. By using cameras and online payments, vehicles no longer need to stop at the crossing, which in theory keeps traffic moving more smoothly.
In practice, while it did remove the immediate bottleneck at the bridge/tunnel, the crossing and approach roads still experience heavy traffic (it’s a busy section of the M25). Additionally, some critics point out that the new system ended up generating a lot of money from penalty fines when drivers forget to pay. Millions of pounds in fines have been issued each year since the change. So, while traffic flow improved at the toll site, drivers unfamiliar with the system sometimes miss the payment, leading to revenue in penalties. The government maintains that the scheme is about managing demand and congestion, and any surplus revenue goes back into transport projects.

What happens if I forget to pay the Dart Charge?

If you forget to pay by the deadline, don’t panic, but do act quickly. The Dart Charge system will issue a Penalty Charge Notice (PCN) to the vehicle’s registered keeper for non-payment. Here’s what to expect:
Penalty timeline: Failing to pay by midnight the day after your crossing triggers a fine of £70 per crossing. This PCN (fine notice) is usually mailed to the address of the vehicle’s registered owner (from the DVLA records). If you pay that £70 penalty within 14 days, it’s reduced to £35 (essentially a 50% early payment discount). However, if you ignore the notice and let 28 days pass without payment, the fine increases to £105. In addition, you’ll still have to pay the original crossing charge on top of the fine. Each crossing you didn’t pay for will get its own penalty, so missing a round trip can mean two fines.
Enforcement: The system uses Automatic Number Plate Recognition (ANPR) cameras to record your vehicle. There’s virtually no escaping it, even if your car is foreign-registered, they track it and can pursue fines across borders in many cases. The Dart Charge enforcement agency will send debt recovery after persistent evaders.
What to do when you realize you forgot: If it’s within the first day or so after the trip, pay immediately, you might get it in before the deadline. If the deadline has passed and a PCN is issued, you’ll have instructions on how to pay the fine. In some cases, if you genuinely forgot and it’s your first ever offense, the Dart Charge may offer a one-time grace period: they sometimes allow first-time forgetters an extra 14 days from the notice date to just pay the original £2.50 toll instead of the hefty fine. This is not guaranteed (policy can change), but historically they’ve given this concession. The penalty notice letter will clarify if that option applies. So read it carefully.
Don’t ignore the notice: Even if you feel it’s unfair, it’s important to either pay or formally appeal it, do not simply ignore a PCN. Ignoring will lead to increased fines and enforcement action.

In short, forgetting to pay will cost you, but acting quickly and responsibly can minimize the damage. In the next sections, we’ll cover how to avoid these fines in the first place and how to appeal if you think you’ve been wrongly fined.

Tips to Avoid Dart Charge Penalties (and What to Do If You Get One)

Nobody wants to receive a £70 fine for a £2.50 toll. Here are some practical tips to help you avoid getting a Dart Charge penalty, and steps to take if you’ve already gotten a fine:

By following these tips, planning ahead, using the available accounts, and staying aware, you can greatly reduce the risk of getting caught out by a Dart Charge penalty. Next, let’s look at what you can do if you believe you were fined unfairly and want to challenge a penalty.

How to Appeal a Dart Charge Penalty (PCN)

If you receive a Penalty Charge Notice from Dart Charge and you think it’s wrong or unfair, you have the right to appeal. Perhaps you did pay on time but the system didn’t register it, or maybe you never received the original notice in the post. The good news is a large majority of Dart Charge appeals are successful, over 80% of appeals were upheld in the first six months of the system’s operation!

Appeal and win… 8 out of 10 drivers do

Over 80% of Dartford Crossing penalty charge appeals succeed, according to Highways England data. This means if you have a legitimate case, there’s a strong chance you can get the fine cancelled.

Here’s how the appeals process works:

Appealing can take some effort, but given the high success rate, it’s absolutely worth doing if you have a valid reason. Many drivers have been issued fines due to technical errors (like misread number plates or payment website issues), and these are the types of cases that often get overturned on appeal. Be clear and concise in your correspondence, and stick to the facts.

Making a Complaint (Non-Appeal Issues)

What if your issue isn’t about a fine, but rather something like poor signage, website problems, or other feedback about the Dart Charge system? In that case, you might want to lodge a complaint rather than an appeal. Complaints won’t cancel a PCN (appeal is the route for that), but they can raise awareness of issues.

For general complaints about Dartford Crossing tolls, such as confusing signs, customer service troubles, etc., you can use the Dart Charge complaints form (available on the official website). This will send your feedback to Highways England’s Dart Charge team. They do review complaints and, over time, if enough people highlight the same issue, it could lead to improvements (for example, better signage or clearer instructions).

Keep complaints separate from appeals: if you have a specific PCN, handle that through the appeals process first. Use the complaint route for broader issues or after your fine issue is resolved, to voice your experience.

Additional Notes and Warnings for Dartford Crossing Users

Using the Dartford Crossing is straightforward once you know the system, but here are a few extra pieces of advice and warnings gleaned from other drivers’ experiences:

Car rental customers often face extra “admin” fees from hire companies if they rely on the rental company to pay the Dart Charge. If you’re driving a hire car or rental vehicle, be aware of how the Dart Charge is handled. Many car rental companies will automatically charge your credit card for the Dartford Crossing toll if you incur one, plus an additional administration fee. We’ve heard reports of admin fees of £35 or more added on top of the £2.50 toll! This can happen if the rental firm pays the toll on your behalf or if they get the penalty notice because you forgot to pay, they’ll pay it and then bill you with a markup.

How to avoid nasty surprises in hire cars: Ideally, pay the Dart Charge yourself using one of the methods above, rather than waiting for the rental company to do it. If you know your rental car’s registration (sometimes provided in advance, or you can pay after you pick up the car but before crossing), you can treat it like your own and pay online or by phone. If that’s not possible, at least ask the rental company at the desk about their Dart Charge policy. Request them to clarify any admin fee and see if you can pre-authorize paying it yourself. Some companies might allow or even require you to pay it; others will do it and bill you. Choose rental companies known for transparent fees, larger ones like Hertz, Enterprise or Sixt often have clearer policies and responsive customer service if issues arise. And always check your credit card statements after, to ensure you haven’t been overcharged for tolls. A bit of diligence can save you from a £37.50 bill for a £2.50 crossing.

The Dart Charge uses a red “C” symbol similar to London’s Congestion Charge, which can mislead drivers. Don’t confuse the Dart Charge with the London Congestion Charge! This is a quirky but costly mistake some drivers have made. The signage approaching the Dartford Crossing says things like “Dart Charge, find us online, pay by midnight tomorrow” and uses a big red C (the symbol for congestion charge) on a blue road sign. There’s no web address listed on these signs, just an instruction to search online. Many well-meaning drivers have done a quick Google search and ended up on the London Congestion Charge payment page (which also has a red C)! They pay £15 or so, thinking they’ve settled the Dartford toll, when in fact they’ve paid the wrong charge to Transport for London. Later, they get a Dart Charge fine because, of course, their Dartford toll wasn’t actually paid. This confusion has been reported frequently.

Don’t get caught out

The result of this mix-up can be serious: you pay five times more than needed (the London congestion toll) and still get hit with a £70 Dartford fine, ouch. To avoid this: always ensure you’re paying the right charge to the right place. The official Dart Charge site is a gov.uk website (or use the phone/Payzone methods). The London Congestion Charge is completely separate and only applies to central London. If you see a red C for Dartford, don’t automatically assume any “C” payment will do, double-check you’re on the Dart Charge page. (Some unofficial third-party sites also use misleading names or ads, we cover that next.) Bottom line: Dartford Crossing toll = Dart Charge (gov.uk), not the London congestion zone.

Check Your Bank Statement for Duplicate Charges

It’s wise to verify your Dart Charge payments after the fact. There have been past instances where drivers paying online discovered they were charged twice for a single crossing. This was reported a few years back, and the AA (Automobile Association) even commented on it, noting that some glitches in the new system had caused duplicate transactions. Highways England acknowledged that with the volume of transactions, occasional errors could happen and apologised when they did.

While the system has likely improved, it’s still a good habit to glance at your card or bank statement after paying the toll. Make sure only the correct amount was taken. If you spot a double charge, contact Dart Charge customer service at 0300 300 0120 to request a refund of the extra payment. They have processes to verify and refund such errors. Don’t pay for the crossing more than you have to!

WARNING: Avoid Unofficial Payment Websites

When paying the Dart Charge online, use the official website only. Unfortunately, some unofficial websites have sprung up that offer to process the Dartford Crossing payment for you, at a hefty markup. These sites often look serviceable and may even appear in search engine ads or results above the official site. They’ll take your details, pay the Dart Charge on your behalf, but charge an extra “service fee” (sometimes 50-60% more expensive than the normal toll).

These third-party sites are not illegal per se, but they are not authorised and can be misleading. They usually do not make it clear that they are not the official Dart Charge portal. For example, one known site (with a name like DartfordCrossingCharges.co.uk) was charging an extra admin fee without prominently disclosing it. They also often have flaws: some don’t even ask for your vehicle type or correct info, which means they might not properly confirm your payment against your vehicle, potentially causing you to overpay or not pay correctly. By contrast, the official gov.uk Dart Charge site will confirm your vehicle make/model when you pay, giving you confidence that the payment is correctly assigned.

How to identify the official site: The genuine payment site is on the Government’s domain (gov.uk). A correct URL is something like www.gov.uk/pay-dartford-crossing-charge. If you’re on any site that isn’t the official gov.uk one (or a known service like the authorized telephone line or Payzone), be cautious. Some unofficial sites try to mimic the look of the official page but will have a different URL and often an extra fee buried in the terms.

Using an unofficial site can result in: spending more money than necessary (why pay £4 for a £2.50 toll?), getting no official receipt, and having no real recourse if something goes wrong (since the transaction wasn’t directly with Dart Charge). In the worst case, if that site fails to pay the Dart Charge on time, you would still be liable for the fine because the responsibility ultimately lies with the driver.

Bottom line: Only trust official channels for payment. The Dart Charge is straightforward to pay via gov.uk, phone, etc., so there’s no need to involve a middleman. If you’re ever unsure, you can find the official link through the main Gov.uk site or even the UK government directory. Paying through the right channel ensures you get an official receipt and means of appeal if anything goes awry.

(For awareness: Since the cashless system started, nearly 3.5 million fines were issued in the first few years, not just due to intentional avoidance, but often because drivers were confused about how to pay. Poor signage like “search Dart Charge online” without a URL contributed to this. We and other organisations have been urging better information to prevent drivers from accidentally falling into these traps. Always make sure you’re informed, share this knowledge with friends who might use the crossing!)

Dartford Crossing and Cyclists: All You Need to Know

What if you’re a cyclist wanting to cross the Thames at Dartford? Bicycles are not allowed to ride through the Dartford tunnels or over the QEII bridge (for obvious safety reasons on a fast, limited-access motorway). However, there is a way for cyclists to cross, and it’s free of charge.

Shuttle service for cyclists: Highways England provides a special pickup service to transport cyclists (and their bikes) through the crossing. You don’t need to book it in advance; it operates on demand during set hours. Here’s how it works:

  1. Go to the pickup point on your side: There are designated meeting points called Kent Point (on the south side in Kent) and Essex Point (on the north side in Essex). These are basically at the ends of the crossing.
    1. Kent Point address: Crossing Offices Roundabout, South Orbital Road, Dartford, Kent, DA1 5PR.
    1. Essex Point address: 859 London Road, Grays, Essex, RM20 3AT. (There’s also access to the Essex Point via the cycle path next to the junction 31 entry slip road of the M25 clockwise.)
      Just cycle to the point closest to you. There will be signs directing cyclists to a yellow telephone at these locations.
  2. Use the free phone at the point: You’ll find a yellow phone box/hatch that connects directly to the Dart Charge control. Lift the phone and it will ring the staff. Simply request the cycle crossing transport service. You don’t need to dial a number, it’s a direct line.
  3. Wait in the designated area: There will be a signed waiting area for cyclists. After you’ve called, wait there with your bike.
  4. Get picked up: A vehicle (usually a small van or truck) specially operated for this purpose will arrive to pick you and your bicycle up. They typically carry a bike rack or have space for a few bikes. They will then drive you through the tunnel/over the bridge to the other side.
  5. Continue your journey: Once dropped off at the corresponding point on the other side, you can resume cycling on your way!

Service hours: Cyclists can use this service 7 days a week, but it’s not 24-hour continuous. The service operates in blocks of time throughout the day and night:

So essentially, it’s available most of the day, with four short off-duty periods in each 24-hour cycle. If you arrive right at a closed period, you might have to wait until the next start time (for example, a cyclist arriving at 9:05 am will wait until 10:30 am for service to resume). Most cyclists won’t encounter the wee hours closures, but do note the midday break around lunch and the evening break.

How long will you wait? Typically, after you call, the vehicle will come within about 15 minutes. It could be a bit longer during very busy times or if they’re temporarily shorthanded, but generally the wait isn’t too bad. It’s a free service, so sometimes there might be multiple cyclists waiting; they might group a few together if possible.

Capacity: If you’re cycling in a large group (more than 3 cyclists), it’s polite to give them a heads-up. The service can only take a few bikes at a time. For big groups or if you have an unusual bicycle (like a tandem, cargo bike, or one with a trailer that might not fit on a standard rack), it’s recommended to contact Connect Plus (the operator) in advance to let them know your plans. They might be able to accommodate better or advise on timing.

Cost: The service is completely free. There’s no toll for bikes and no charge for the pickup. Enjoy the unique “ferry” across the Thames at no cost!

This shuttle is a great solution that ensures cyclists have a safe way across the river at Dartford. Just remember: you cannot cycle on the bridge or in the tunnels under your own power, always use this service.
