Auto-pay Dart Charge, in one page
The official Dart Charge auto-pay is the pre-pay account. A one-time £15 deposit, an optional Direct Debit, and the crossing charges itself thereafter. This page walks through the setup, the deduction logic, the top-up triggers, and how to cancel cleanly.
The five steps to active auto-pay
Total time: about 10 minutes. The pre-pay £2.80 rate kicks in the first time a camera reads your plate after the account is live, usually within an hour of setup.

How the per-crossing deduction works
Each gantry on the A282 carries two sets of ANPR (Automatic Number Plate Recognition) cameras: one in the lead-up to the bridge or tunnel mouth, one immediately after. The post-crossing read is the trigger: when it confirms a registered vehicle has crossed, the system deducts the appropriate pre-pay rate from your balance and emails a confirmation by midnight.
You won't get a per-crossing email if you ask for daily or monthly summaries instead. The deduction happens in either case. If the cameras can't read your plate (heavy rain, snow, a tail-gate covering the rear plate), the system may bill the PAYG rate. There is a process to claim the difference back, but it's a known friction point.
| Vehicle class | Auto-pay deducts | Saved vs PAYG |
|---|---|---|
| Car (Class B) | £2.80 | 70p |
| Van under 3.5t (Class B) | £2.80 | 70p |
| 2-axle goods (Class C) | £3.60 | 60p |
| Multi-axle HGV (Class D) | £7.20 | £1.20 |
| Motorcycle / disabled tax | Free | n/a |
When the Direct Debit top-up triggers
The trigger threshold is £10. As soon as your auto-pay balance drops below £10, a Direct Debit instruction goes out to your bank for a top-up. The standard top-up is set to take the balance back up to a fixed level, which you choose during setup. Most users pick one of three:
- £15: back to the minimum. Suits occasional crossers (once or twice a month).
- £30: about a month of car commuting. The default suggestion.
- £60: two months of car commuting or one month of 2-axle goods.
The Direct Debit usually settles in 2-3 working days. If you cross during that window, the deduction still happens; the balance simply goes slightly negative until the top-up clears. The system won't reject crossings as long as the account is in good standing.
Manual top-up if you don't want Direct Debit
You can run auto-pay without a Direct Debit. The pre-pay rate still applies; you just top up manually. Three differences worth knowing:
- No auto top-up. When the balance drops below the cost of a crossing, the next read bills you at the £3.50 PAYG rate and the account emails you to top up.
- Email reminders at £5. The system warns you by email when the balance hits £5, so you get a few crossings of grace period.
- Manual top-ups by card. Log in, pick a top-up amount, pay by debit or credit card. Funds usually credit within 30 minutes.
Cancelling auto-pay cleanly
Most people who close a Dart Charge auto-pay account do so for one of two reasons: moving away from the M25, or switching to a vehicle that no longer crosses. Two ways to wind it down.
Option 1: cancel the Direct Debit, keep the account
Useful if you might cross again in 6 months. The account stays in pre-pay mode; you just spend down the balance and top up manually if needed. Account stays free.
Option 2: close the account entirely
Log in, choose "Close account", confirm. The remaining balance is refunded to your card or bank within 10 working days. Vehicle plates are removed from auto-pay, so future crossings revert to PAYG £3.50.

Auto-pay FAQ
Is there auto-pay for the Dartford Crossing?+
Yes. The Dart Charge pre-pay account is the auto-pay system. After a £15 minimum deposit and registering one or more vehicle number plates, every crossing is deducted automatically when the ANPR camera reads the plate. There is no separate auto-pay product.
What's the difference between auto-pay and a Direct Debit?+
Auto-pay is the experience at the crossing: cameras read the plate, the balance drops by £2.80, no action from the driver. The Direct Debit is the back-end funding mechanism: it tops the balance up from your bank when it hits £10. Two parts of the same product. You can have a pre-pay account without a Direct Debit if you prefer to top up manually.
How long does it take to set up auto-pay?+
About 10 minutes. You'll need your vehicle registration number, a debit or credit card for the £15 deposit, and bank details for the Direct Debit if you want auto-top-up. The account is active and reading plates within an hour, in practice, so you can set it up the same morning you cross.
Can I add multiple vehicles to one auto-pay account?+
Yes, up to 20 vehicles. All share the same balance and the same Direct Debit. Useful for couples, families, small fleets and households where any of several vehicles might cross.
What happens if my balance runs out mid-month?+
If your balance is below the £2.80 cost of a car crossing, the Direct Debit triggers a top-up. If the Direct Debit is not set up (manual top-up mode), the crossing is billed at the £3.50 PAYG rate and you'll get an email asking you to top up. If you ignore that, the next crossing leaves you without payment, the £70 PCN deadline applies.
Can I cancel auto-pay and get my deposit back?+
Yes. Log into the Dart Charge account, choose 'Close account', and any remaining balance over £0.01 is refunded to the same card or bank account within 10 working days. You can keep the account open and just cancel the Direct Debit if you want to switch back to manual top-up.
