“Best” at 4am isn't the plushest car — it's the one that is definitely outside at 4am, at the price agreed, driven by someone who planned to be awake. Here's how the options genuinely rank at that hour, and the five-question checklist we'd run on any firm — including us.
Send postcode + airport + flight time
The winner at 4am — if the allocation is real. A named driver got your job the evening before, planned their sleep around it, and a night desk owns the booking end to end. The fare was fixed while the world was calm. That's us, but the honest point is bigger: any firm that passes the checklist below is a good 4am choice. Most that quote cheapest don't.
A gamble with decent odds in central London and long odds in the suburbs. Your “booking” is a request that fires when your alarm does; supply is thin, surge tracks the dawn wave, and a cancelled match at minute nine restarts a clock you don't have. If a sane quote appears with a car two minutes out, take it — but don't make it the only plan for a flight you can't miss.
Worth checking, honestly: some airports have night coaches that work well if you're near a stop and travelling light. But most first trains land after the dawn-wave bag-drop cutoffs, and a 4am flight-day starts before nearly all of them. As a backup they're thin; as a primary plan for a 6am departure, they usually fail the arithmetic before they fail you.
1. Who is driving me, and when do they get the job? 2. Is the price fixed now, including the airport's charges — and can it move by morning? 3. Is anyone awake at your firm at 3:30am if I need to call? 4. If the driver can't make it, who comes instead — and who tells me? 5. Is there a night premium? A confident firm answers all five in one message. Hesitation on any of them is your answer.
1. A named driver, allocated the evening before. 2. Fixed at booking, airport charges and the Crossing inside, immovable by morning. 3. Yes — the night desk is staffed, and it answers. 4. The nearest covering driver, re-tasked by the dispatcher, who calls you first. 5. No premium — same rate card at 4am as 4pm. The mechanics behind each answer are in the guaranteed pickup guide and the early-morning guide.
Fixed saloon fares, locked at booking, identical at every hour — the dawn wave never touches them. All airport charges inside.
Message your postcode and flight time for the exact fare and the pickup time we'd choose ourselves.
One message this evening gets a locked fare, a named driver, and a pickup time worked back from bag drop. The best 4am taxi is the one you never have to think about at 4am.
