About CMT
CMT UK (cmt.london) provides card payment terminals, e‑hailing, and dispatch technology specifically for licensed London black cabs. They supply the in‑vehicle card machines and back‑end processing that allow passengers to pay taxi fares by debit/credit card, contactless, mobile wallets (e.g., Apple Pay/Google Pay), and in some cases via integrated taxi apps. CMT works with taxi fleets and individual drivers but does not itself operate the taxis; it is the payment and technology provider that securely processes your fare on behalf of the driver or fleet.
A CMT charge usually appears on your bank or card statement when you pay for a journey in a London black cab that uses a CMT payment terminal or an associated e‑hailing/booking service powered by CMT. The most common transactions are one‑time taxi fares, sometimes including a discretionary tip or a small card/booking fee if applicable. You may also see temporary authorization holds when a driver starts a card transaction or when you add a card to an app that uses CMT’s processing; these can appear as a small test amount (e.g., £0–£1) or a pre‑authorization up to the estimated fare, which is later adjusted to the final amount or released.
If you do not recognize a CMT charge, first think back to any journeys you took in a London black cab around the transaction date and check your email or app for ride receipts, which often list CMT or the taxi number. You can usually request a receipt directly from the driver at the end of the journey, from the taxi app you used, or by contacting your card issuer for transaction details such as date, time, and merchant ID. For unresolved billing questions (incorrect fare, duplicate charge, or a hold that hasn’t dropped off), you can contact the taxi company or app you booked through and also reach CMT via the contact details on cmt.london; provide the last four digits of your card, charge amount, date/time, and any receipt or cab number so they can investigate and coordinate with the driver and your bank if needed.

Why do I see a CMT UK charge on my statement after taking a London black cab?
CMT UK processes electronic card payments for many licensed London black cabs, so the merchant name may show as “CMT”, “CMT UK”, or a similar variation instead of the individual driver or taxi company. The charge typically reflects the metered fare plus any tip you added and, where applicable, a small card or booking fee allowed by local regulations. The payment is collected on behalf of the driver or fleet and then settled to them by CMT.
What typical amounts or patterns do CMT taxi charges have?
CMT charges usually match the metered taxi fare in pounds sterling (GBP), such as £8–£40 for shorter central London trips, but can be higher for longer journeys or trips to airports. You may see line items that include the fare plus a tip you added on the terminal screen and sometimes a fixed card/booking fee where permitted. The description on your statement may reference “CMT”, “CMT London”, or a taxi/booking reference, and each ride appears as a separate one‑time charge.
Why do I see a small CMT UK authorization or a pending amount that’s higher than my final fare?
When you tap or insert your card in a CMT terminal, the system may place a temporary pre‑authorization to confirm your card is valid and that funds are available. This can appear as a small test amount (often £0–£1) or as a hold up to the estimated maximum fare for the trip. Once the final fare is completed, the pre‑authorization is either adjusted to the exact fare or released by your bank, usually within a few business days depending on your card issuer’s policies.
Can CMT UK charge me on a recurring or subscription basis?
For passengers, CMT UK transactions are almost always one‑time charges for individual taxi rides, not subscriptions. If you see repeated CMT charges, it usually reflects multiple journeys taken on different dates or multiple card attempts for a single trip. Some taxi apps that integrate CMT allow you to store your card for future rides, but you are still billed per trip rather than through a recurring subscription plan.
How do I get a receipt or proof of payment for a CMT taxi charge?
At the end of your journey, the driver can print a paper receipt directly from the CMT card terminal, showing the fare, tip (if any), and time/date. If you booked via a taxi app that uses CMT for processing, you can usually download or email your receipt from the app’s ride history section. If you no longer have the receipt, you can contact the app’s support or use the contact form on cmt.london with your card’s last four digits, amount, date/time, and approximate pickup/drop‑off locations so they can help locate the transaction.
How do I dispute an incorrect or duplicate CMT taxi charge?
First compare the charge amount against your taxi receipt or ride summary in the booking app to ensure any tip or fees are accounted for. If you believe you have been overcharged or see a duplicate transaction, contact the taxi company or app provider you used and provide the trip details so they can review the meter record and payment log. You can also reach out via cmt.london with your transaction details; CMT can check their processing records and work with the driver or fleet. If the issue is not resolved, your bank or card issuer can initiate a formal dispute (chargeback).
How can I contact CMT UK about a charge I don’t recognize?
Visit cmt.london and use the published contact options, which typically include an online contact form and support email and/or phone number for payment queries. When you reach out, include the charge amount, transaction date, the first six and last four digits of your card number (never send the full number), and any receipt, cab number, or booking reference you have. This information helps CMT quickly identify the specific payment and advise whether it relates to a London taxi journey you took.
What should I do if I never took a taxi but see a CMT UK transaction?
If you are sure you did not ride in a London black cab or use a taxi app around the date of the charge, treat it as potential card misuse. Immediately contact your bank or card issuer to report the unrecognized transaction, request a card block or replacement if needed, and follow their fraud dispute process. You may also provide the transaction details to CMT via their website so they can flag the payment in their system and assist any investigation by your bank.
