FAQs
Do Heathrow rank black cabs accept American Express?
Yes, all of them. TfL Conditions of Fitness Section 24 mandates AMEX acceptance on every London Hackney carriage. UK acquirer rates on AMEX run 2.0% to 3.0% depending on acquirer. Refusing AMEX on a Heathrow rank cab is a TfL licensing offence.
What is the average card-acceptance rate at Heathrow taxi ranks?
92% of Heathrow Terminal 5 rank black cab fares were paid by card in Q1 2026, the highest card-acceptance share of any London taxi location. Driven by international business-traveller customer mix (most arriving without GBP cash).
How do Heathrow taxi drivers handle multi-currency settlement?
Standard UK acquirers settle in GBP only. Customer's home bank handles the currency conversion on their statement. For drivers wanting multi-currency settlement direct (GBP, EUR, USD), Revolut Card Reader is the cheapest UK option. Adyen also offers multi-currency for fleet-scale operators.
Can Heathrow-transfer drivers add an airport-rank surcharge to the fare?
No surcharge for card payment specifically (UK Consumer Rights illegal since January 2018). Heathrow Express Charge (currently £6.10 in 2026) is a separate metered supplement applied to fares departing from the airport regardless of payment method.
How we rank
Rankings are built by desk research from each provider's published rates, upfront costs, contract lengths and settlement terms, held in a dated record per terminal (last-reviewed date shown on this page) and re-checked when published pricing changes. We do not hands-on test every device; specs are taken from provider documentation and cited. No provider pays for inclusion or position. MerchantHQ is an introducer: acquirers, including some brands ranked here, pay us commission on completed introductions. Commission never affects a ranking. See our methodology and how we are funded.
