★ Key takeaway
London ULEZ AutoPay costs £10/year per vehicle and debits a linked card automatically on detection. Other UK CAZs (Bath, Bradford, Birmingham, Bristol, Portsmouth, Sheffield, Tyneside) use the free central gov.uk CAZ account with optional auto-pay. Cancellation is self-serve in both systems. Refunds issue within 10 working days for duplicate or incorrect charges. |
UK Clean Air Zone (CAZ) and Low Emission Zone (LEZ) payment systems offer auto-pay options that remove the need to remember individual daily charges, charging linked payment cards automatically when vehicles enter charging zones. London's ULEZ AutoPay is a TfL-administered paid subscription at £10/year per vehicle, reflecting its integrated approach with Congestion Charge and Low Emission Zone. The non-London CAZs (Bath, Bradford, Birmingham, Bristol, Portsmouth, Sheffield, Tyneside) use the central gov.uk CAZ account, which offers free auto-pay without subscription fees. Both frameworks allow self-serve cancellation, refund processing for duplicate or incorrect charges, and vehicle list management for operators with multiple vehicles. This guide covers each system's setup process, fee structure, cancellation procedure, refund handling, and how operators of mixed UK fleets can coordinate CAZ payments across zones efficiently.

London ULEZ AutoPay: how it works
TfL's AutoPay for London ULEZ, Congestion Charge and Low Emission Zone uses a £10/year-per-vehicle subscription model, with a monthly direct debit collecting the accumulated daily charges. Registration is at tfl.gov.uk/modes/driving/auto-pay, requiring the vehicle registration number, a UK debit or credit card, and a billing address. Monthly bills are calculated on detected entries and debited on the 15th of each following month.
AutoPay provides peace of mind for regular London visitors and commuters: ULEZ charges are £12.50 daily for non-compliant cars and £100 daily for non-compliant HGVs, so missing a single day's payment risks a £120 PCN. The £10/year subscription fee is typically recovered within 1-2 enforcement avoidances per year, making AutoPay cost-effective for anyone entering the zone 10+ times annually.
The gov.uk central CAZ account
Non-London CAZs use the central gov.uk CAZ account at gov.uk/clean-air-zones. The account covers Bath, Bradford, Birmingham, Bristol, Portsmouth, Sheffield and Tyneside simultaneously, with no subscription fee. Users register with an email address, add vehicles by registration number, link a payment card, and optionally enable auto-pay.
The gov.uk auto-pay debits the linked card on the same day the vehicle is detected entering any participating CAZ, with email notification of the transaction. Users can also pay manually for individual entries via the same account within the 6-day window before or after entry. This flexibility suits users who make occasional zone entries and prefer transaction-by-transaction confirmation.
Setting up AutoPay: step by step
For London ULEZ AutoPay, users go to tfl.gov.uk/modes/driving/auto-pay, click "Set up AutoPay", create a TfL account (or sign in if existing), add vehicles (up to 5 per personal account, unlimited for business fleet accounts), link a debit or credit card, and agree to the terms. First payment comprises the £10/year subscription plus any accumulated charges. Business fleet accounts have separate registration at tfl.gov.uk/business with additional options for invoice payment.
For the gov.uk CAZ account, users go to gov.uk/clean-air-zones, click "Pay the daily charge", create an account with email and password, add vehicles, link a payment card, and toggle auto-pay on. Zone coverage is automatic across all participating English CAZs. No fee applies, and auto-pay can be switched off at any time.
Cancellation and vehicle removal
London ULEZ AutoPay cancellation is self-serve via the TfL account dashboard. Users can remove individual vehicles or cancel the subscription entirely. Pro-rata refunds of the £10 subscription are not normally provided, but accumulated unpaid daily charges become due immediately on cancellation. Selling a vehicle requires the seller to remove it from AutoPay within 7 days to avoid being liable for new charges under the buyer's ownership.
Gov.uk CAZ account cancellation is also self-serve. Users can remove individual vehicles or delete the entire account. Since no subscription fee applies, cancellation has no refund implications. Best practice on vehicle sale is to remove the vehicle from the account immediately and notify DVLA via the V5C transfer, ensuring CAZ enforcement systems update to the new keeper.
Refunds for duplicate or incorrect charges
Refunds are available where a charge has been debited in error: duplicate entries billed twice, vehicles subsequently identified as compliant (Historic Vehicle reclassification, MOT-evidenced Euro 6 upgrade), or administrative errors. Users request a refund via the account dashboard with supporting evidence. Refunds issue within 10 working days to the original payment card.
For contested charges where the vehicle's compliance is disputed (aftermarket emission system, retrofit installation), users can appeal before paying or request refund after paying with evidence. Providing a CVRAS retrofit certificate or manufacturer Euro 6/VI certification typically resolves these disputes within the refund window.
Fleet accounts and multi-vehicle operators
Operators with commercial fleets use dedicated fleet accounts on both systems. TfL Business Fleet supports unlimited vehicles with invoice billing, consolidated reporting and API integration for telematics. Gov.uk CAZ account supports up to 100 vehicles with bulk upload via CSV. For operators with fleets exceeding 100 vehicles, multiple accounts or third-party compliance management platforms (Microlise, Samsara) provide the coordination layer.
Fleet account reporting includes vehicle-level entry logs, zone-level charge breakdowns, monthly consolidated invoices, and exportable CSV data suitable for accounting integration. Larger operators routinely integrate CAZ invoices with their ERP systems (SAP, Oracle, Sage) for automated cost allocation to cost centres, routes or contract customers. API-driven integration is available to approved partners on both TfL and gov.uk platforms.
Common AutoPay pitfalls to avoid
Expired payment cards are the most common cause of failed AutoPay transactions. Users should update card details whenever their bank issues a new card, typically at 3-year intervals. Both TfL and gov.uk send email reminders before card expiry, but users occasionally miss these and end up with unpaid charges becoming PCNs. Setting calendar reminders for card expiry dates reduces this risk.
Selling a vehicle without removing it from AutoPay is another common mistake. The previous keeper remains liable for charges until the vehicle is removed from the account, even after V5C transfer to the new keeper. DVLA informs CAZ enforcement of keeper changes within 5-10 working days, but AutoPay continues until the account holder actively removes the vehicle. Best practice is to remove the vehicle on the day of sale and confirm removal via the account dashboard.
International visitors and non-UK registered vehicles
International visitors driving non-UK registered vehicles into UK CAZs must pay daily charges in the same way as UK drivers. TfL ULEZ and gov.uk CAZ accounts accept non-UK payment cards and non-UK addresses, so visitors can register AutoPay for their trip duration and then cancel on departure. The TfL £10 AutoPay fee is payable regardless of visitor status.
Visitors arriving without prior AutoPay setup can still pay via the gov.uk or TfL payment web pages after entry, within the 6-day window. Failure to pay results in PCN issuance to the vehicle's registered address, which is then pursued via international enforcement agreements between UK authorities and the visitor's home country. Non-payment of UK PCNs can also affect future UK car rental and hire car bookings.

| ★ EDITOR'S VERDICT AutoPay is cost-effective for anyone making regular zone entries: 10+ London ULEZ entries per year recovers the £10 subscription in PCN-avoidance alone, and the gov.uk CAZ account has no downside for non-London entries given its zero fee. Both systems are self-serve on setup and cancellation, both handle refunds promptly, and both integrate with typical fleet management workflows. Drivers making only occasional zone entries can rely on standard payment within the 6-day window, avoiding subscription overhead. Operators should treat AutoPay as default for any vehicle entering charging zones more than monthly, with the small administrative lift recovered many times over in avoided PCNs. |

Refunds for duplicate or incorrect charges process within 10 working days to the original payment card. Contested charges involving vehicle compliance disputes may take longer if documentary evidence needs review.
