Dartford Crossing Cost

Forgot to pay the Dart Charge? Here's what to do.

A £3.50 crossing turns into £35, then £70, then £105 if ignored. The cost of acting now is small. The cost of waiting is large.

How late are you?

Pick the row that fits. Each one tells you exactly what to do.

Within 24 hours

You're still on time. Pay now.

The deadline is 11:59pm the day after you crossed. If that hasn't passed, you can pay at the standard rate and there is no penalty.

Pay at gov.uk
1 to 3 days late

Try to pay anyway. It often works.

The system doesn't generate a PCN immediately. Crossings paid 1-3 days late are sometimes accepted at the standard rate. Worth a shot.

Try paying online
A PCN has arrived

Pay it within 14 days for the £35 reduced rate.

The PCN itself includes a payment reference and link. Acting fast saves £35. If you think the PCN is wrong, see the appeal route below.

See the fines guide
Multiple weeks late, no PCN

Wait. Ringing Dart Charge sometimes flags it.

If a PCN hasn't arrived after 4 weeks, calling 0300 300 0120 to confirm the unpaid crossing can sometimes still let you pay the original charge. Document the call.

Remember

The deadline is 11:59pm the day after you crossed.

Cross Tuesday at 2pm? Pay by Wednesday 11:59pm. Cross Saturday morning? Pay by Sunday night. There's no Monday-only window.

Common late-payment questions

Can I still pay the Dart Charge 5 days late?+

The official answer is no. In practice, you can sometimes still pay online for a few days after the deadline before the system flags it. Try and see, or call 0300 300 0120. Worst case, you pay £3.50 instead of £35.

My passenger says they got a Dart Charge PCN but I don't think we crossed.+

ANPR cameras occasionally misread plates. Request the photo evidence Dart Charge holds (cite the PCN reference) and challenge formally if the image doesn't show your vehicle.

Is the £35 reduced PCN rate guaranteed?+

Only if you pay within 14 days of the PCN issue date (printed on the notice). After 14 days, the fine returns to £70. After 28 days, it rises to £105.

My Dart Charge PCN went to my old address.+

The PCN is sent to the address on the V5C. Update your DVLA address immediately and contact Dart Charge to request a re-issue. The first-PCN grace policy may apply.
