Setting up the Dart Charge Direct Debit
The Direct Debit is the funding side of the Dart Charge pre-pay account: it takes money from your bank when the balance gets low. Without it, you have to top up manually by card. This page covers setup, the trigger threshold, what happens if it bounces, how to change your bank, and how to wind it down.
Setting up the Direct Debit from scratch
Three steps. The whole process is online; you don't need to call or visit a branch. Sort code and account number are the only details Dart Charge takes; they don't hold the card on file separately.
- 1
Open the pre-pay account
A £15 minimum opening deposit by debit or credit card. This funds your first 5 car crossings.
- 2
Choose your top-up amount
£15, £30 or £60 are the three defaults. You can edit later; pick the one that matches your monthly crossing volume.
- 3
Add bank details
Sort code, account number, account holder name. Bank confirms via the Direct Debit Guarantee 4-6 working days later.
How the top-up trigger works
The threshold is fixed at £10. When your account balance drops below £10 after a crossing, the next-day batch process flags the account for top-up and a Direct Debit instruction goes to your bank that evening. Funds settle in your Dart Charge balance 2-3 working days later.
- Balance check is once per day. Crossing twice in a single afternoon and dropping to £5 won't trigger an emergency top-up. The check runs overnight.
- Crossings during top-up settlement are still billed at pre-pay rate. The balance can go slightly negative until the top-up clears. Dart Charge doesn't reject crossings during settlement.
- Top-up amount is fixed. Whatever you chose during setup (£15, £30 or £60) is the amount of every top-up. To change it, log in and update the "Manage account" section.
What happens if the Direct Debit bounces
Insufficient funds, closed account, mismatched name on the form: these all cause a Direct Debit to bounce. Dart Charge gets a notification from BACS the same day and emails you. Three things happen in sequence.
- Email and SMS notification on the day the bounce is recorded. The message identifies which crossing's top-up failed.
- 7-day grace period. The account stays in pre-pay mode for 7 working days, during which crossings continue to bill at £2.80. You can top up by card to clear the issue without a re-Direct Debit.
- Account suspension after 7 days. If you haven't resolved the bounce within a week, the account reverts to PAYG £3.50 and the auto-top-up stays cancelled until you set it up afresh.
Recovery is quick: a single manual top-up by card and a fresh Direct Debit instruction restores normal service within 4-6 working days. No PCN follows from a bounced Direct Debit as long as the underlying crossings have all been paid (which they will have been at the £2.80 pre-pay rate during grace).
Switching bank account
The Current Account Switch Service handles most bank-to-bank moves automatically. Direct Debits are redirected for 36 months. If you've done a CASS switch, the Dart Charge Direct Debit should follow without action.
If you're changing bank without a CASS switch (rare; mainly relevant for international moves or some business accounts), update Dart Charge manually:
- Log into the Dart Charge website
- Open "Manage Direct Debit"
- Enter new sort code and account number
- Confirm. The change takes effect at the next top-up cycle
The Direct Debit Guarantee covers any error in the switch for 8 weeks. Your bank will reverse any incorrect debit on request.
Cancelling the Direct Debit but keeping the account
Useful if you've moved out of the area and don't need automatic top-up any more, but still want to keep the £15 deposit running for occasional crossings.
- Log into Dart Charge, choose "Cancel Direct Debit".
- Pre-pay £2.80 rate continues as long as the balance covers crossings.
- Email reminders sent at £5 balance. Manual top-up by card any time.
- Drop to £0 and the next crossing bills at PAYG £3.50 instead.
- You can re-enable the Direct Debit any time from the same screen.

Direct Debit questions
What is the Dart Charge Direct Debit?+
It's the automatic top-up that funds your pre-pay account from your bank. When the balance drops below £10, a Direct Debit instruction goes to your bank for a top-up. Funds settle in your Dart Charge balance in 2-3 working days. Without the Direct Debit you can still have a pre-pay account, you just top it up manually by card.
What's the minimum top-up?+
£10 minimum each top-up cycle, but most users set it to £15, £30 or £60 to match their crossing frequency. The minimum opening deposit when you first set up the account is £15.
Can I change my Direct Debit bank account?+
Yes, online via the Dart Charge website. Log in, choose 'Manage Direct Debit', enter the new sort code and account number. The Direct Debit Guarantee covers you for 8 weeks of refund if anything goes wrong with the switch. The change takes effect from the next top-up cycle.
What if my Direct Debit bounces?+
Dart Charge will email and SMS you the same day. You have 7 working days to fix it before the account is suspended. During suspension, crossings are billed at the £3.50 PAYG rate. Once you re-establish funding (manual top-up or a successful Direct Debit retry), the account reverts to pre-pay £2.80.
Can I cancel the Direct Debit but keep the account?+
Yes. Log in, choose 'Cancel Direct Debit'. The pre-pay account stays open in manual top-up mode. You'll get email reminders when the balance drops below £5. Useful if you've moved out of the area but might cross again occasionally.
Will I get my £15 deposit back if I close the account?+
Yes, plus any unspent balance over £0.01. The refund goes back to the same bank account or card that funded the deposit, usually within 10 working days. There is no fee for closing the account.
