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
A free-text amount, not a menu, floored at £15 by both the terms and the form. Anything under £15 is not credited at all, so match the amount to your monthly crossing volume.
- 3
Add bank details
Sort code, account number, account holder name. The mandate asks you to allow 10 working days for the first payment to be received.
How the top-up trigger works
You choose the threshold, within a floor Dart Charge sets. The general terms and conditions put it as: you "can set the minimum balance threshold (subject to a £5.60 minimum) which will trigger an Auto-Top-Up payment" (clause 5.4). If you do not choose one, the gov.uk application form states the same figure as the standing trigger: accounts "must have a minimum of £5.60 credit" and "top-up automatically when they go below £5.60 (or your chosen amount)".
That gov.uk page carries two attachments and only one of them is your contract. Take the one headed "applying to account holders from 1 September 2025". The other is headed "up to 31 August 2025", and three of the four figures below are lower in it.
| Threshold | From 1 Sep 2025 | To 31 Aug 2025 (expired) | Where it is written |
|---|---|---|---|
| Lowest trigger you may chooseTerms, clause 5.4 | £5.60 | £5.00 | Terms, clause 5.4 |
| Standing trigger if you choose noneApplication form, page 1 | £5.60 | £5.60 | Application form, page 1 |
| Minimum top-up, any methodTerms 7.3(c) and 5.7; form page 4 | £15.00 | £10.00 | Terms 7.3(c) and 5.7; form page 4 |
| Balance that suspends the accountTerms, clause 6.2(c) | £2.80 | £2.00 | Terms, clause 6.2(c) |
- The trigger and the top-up amount are two different floors. These get confused. The trigger is the balance that sets a top-up off, and it is £5.60 whether you pick it or let it stand. The top-up amount is how much then arrives: clause 7.3(c) puts that at £15.00 and says payments below £15.00 are not credited at all.
- Under £2.80 and the account is suspended. Clause 6.2(c) suspends an account whose credit balance falls below £2.80, and 6.2(a) and (b) suspend it on any crossing the balance cannot cover. Our arithmetic: at the £2.80 pre-pay car rate that floor is one crossing and the £5.60 trigger is two, so a car driver gets two crossings of warning.
- An account does not stop a fine. Clause 6.1 is explicit: having an account "will not prevent a Penalty Charge Notice being issued if your Account balance is insufficient to cover any Charges incurred". The Direct Debit is what keeps that from happening.
- You can change the top-up amount whenever you like. Clause 5.7 lets you change it at any time through the website, or by giving at least 15 days prior notice in writing with an amended mandate if required.
What happens if the Direct Debit bounces
Insufficient funds, a closed account, a mismatched name on the mandate: these all cause a Direct Debit to fail. The Dart Charge terms, rather than any guesswork, set out what follows. Four stages, with the clause behind each.
- Your card is charged instead (clause 5.2). "If payment via the Mandate fails at any time for any reason, we will automatically deduct the relevant Charges from your credit or debit card using the details you have provided to us." So the first line of defence is the card on file, not a suspension.
- Suspension (clause 6.2). The account is suspended when a charge is incurred that the balance cannot cover, when the balance cannot settle a crossing for the cheapest class on the account, or when the credit balance drops below £2.80.
- Notification and 5 days (clauses 6.3 and 6.4). You are told to pay for any unpaid crossings and to top up to at least the minimum balance threshold. Do neither within 5 days of that notification and the account is classified as Dormant and becomes eligible for closure.
- Closure after three failures (clause 9.1(a)(ii)). Dart Charge may close the account if the mandate fails on more than three occasions, and reserve the right to refuse to open another for you.
The thing worth knowing is clause 6.1: an account does not insulate you from a fine. "Having an Account will not prevent a Penalty Charge Notice being issued if your Account balance is insufficient to cover any Charges incurred by your vehicle(s)." A failed Direct Debit with no working card behind it can therefore end in a £70 PCN, not just a lost discount.
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 printed on the Dart Charge mandate covers errors in the switch: "If an error is made in the payment of your Direct Debit, by the organisation or your bank or building society, you are entitled to a full and immediate refund of the amount paid from your bank or building society." It also promises normally 10 working days notice of any change to the amount, date or frequency.
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.
- Cancel with your bank, and tell Dart Charge: clause 7.3(g) requires you to notify them immediately.
- Pre-pay £2.80 continues while the balance covers the crossing. Clause 7.3(i) withdraws the discount for any crossing it cannot.
- Top up manually by card, by phone on 0300 300 0120, or by post.
- Below £2.80 the account is suspended (clause 6.2(c)), and 5 days later it is dormant.
- Cancel the mandate without telling them and clause 9.1(a)(i) lets them close the account.

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. The gov.uk application form says accounts top up automatically when they fall below £5.60 or an amount you choose, and clause 5.4 of the Dart Charge terms, in the version applying to account holders from 1 September 2025, lets you set that threshold subject to a £5.60 minimum. So £5.60 is both the standing trigger and the lowest trigger you are allowed to pick. 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?+
£15, and the same £15 opens the account. Clause 7.3(c) of the terms applying to account holders from 1 September 2025 states that the Minimum Top Up, whether by Auto-Top-Up or any other method, is £15.00, and that payments of less than £15.00 will not be credited to the account. The current gov.uk application form asks for a top-up amount with the same £15 minimum, and clause 5.7 applies that £15.00 floor again if you later change the amount. The figure went up with the 1 September 2025 terms, so check the attachment heading before quoting any number: gov.uk still publishes the earlier, lower set alongside it under the heading 'applying to account holders up to 31 August 2025'.
Can I change my Direct Debit bank account?+
Yes. Log in to the Dart Charge account, go to Account management and Payment, and update the bank details. The Direct Debit Guarantee printed on the Dart Charge mandate form covers the switch: if an error is made in the payment of your Direct Debit, by the organisation or your bank or building society, you are 'entitled to a full and immediate refund of the amount paid' from your bank. The same Guarantee says you will normally be told 10 working days in advance of any change to the amount, date or frequency.
What if my Direct Debit bounces?+
The terms set out the sequence. Clause 5.2 says that if payment via the mandate fails, Dart Charge will automatically take the charges from the credit or debit card you gave them. Clause 6.2 suspends the account where a charge is incurred with insufficient funds, or the balance cannot cover the cheapest class of crossing, or the credit balance is under £2.80. Clause 6.3 then notifies you to pay for unpaid crossings and top up to at least the minimum balance threshold, and clause 6.4 gives you 5 days from that notification before the account is classified as Dormant and becomes eligible for closure. Clause 9.1(a)(ii) allows closure outright if the mandate fails on more than 3 occasions.
Can I cancel the Direct Debit but keep the account?+
Yes, but tell Dart Charge as well as your bank. Clause 7.3(g) requires you to notify them immediately if you cancel or alter the mandate, and clause 9.1(a)(i) lets them close the account if you cancel it for any other reason than the ones the terms permit. Done properly, the account stays open in manual top-up mode and keeps the £2.80 rate for as long as the balance covers the crossing.
Will I get my £15 deposit back if I close the account?+
Yes. The deposit is balance, not a fee, so it comes back with anything else unspent. National Highways says the money held at closure is refunded by the same payment method it arrived on, and that refunds to a debit or credit card can take up to 10 working days, longer by cheque. If an inactive account is closed by Dart Charge, clause 8.4 says they will endeavour to refund the credit balance to the bank account on the mandate, and clause 8.5 lets you claim it for 7 years afterwards. There is no closure fee.
