Hackney carriages can be hailed in the street and wait at ranks as well as pre-booked; private hire (minicabs) must be pre-booked through a licensed operator. That changes dispatch: private hire lives or dies by the booking desk, while hackney firms still need answering for their pre-booked and account work. An outsourced desk covers both.
People use "taxi" for both, but in UK licensing terms a hackney carriage and a private hire vehicle are different animals, and the difference matters the moment you think about dispatch. One can pick a fare off the street; the other can't. Here is the distinction in plain terms and what it means for answering and dispatch.
The core difference
Two rules separate them, and everything else follows from these:
- Hackney carriages (black cabs and their regional equivalents) can be hailed in the street, wait at ranks, and also take pre-bookings
- Private hire vehicles (minicabs) cannot be hailed or ranked — every journey must be pre-booked through a licensed operator
- Both require driver and vehicle licensing through the relevant authority — TfL in London, the local council elsewhere
How it changes dispatch
For private hire, the booking desk is the whole business — no booking, no lawful job, so answering reliability is everything. For hackney, street and rank work happens without a desk, but the pre-booked and account side still runs through the phone. A hackney firm chasing hotel contracts, account customers, and pre-booked airport runs needs answering just as much for that slice of work, even if the random street hail doesn't touch the office.
Real-time driver coordination and routing around the clock — overnight, weekends, holidays, and peak surges covered.
Why hackney firms still need answering
It is tempting to assume a hackney operator doesn't need a booking desk because cabs can be hailed. The pre-booked and account work says otherwise. Hotels, regulars, account billing, and advance airport bookings are steady, higher-value work, and they all come through the phone. Miss those calls and you lose the predictable money while you wait on the unpredictable street fare.
Where an outsourced desk fits each
For private hire, an outsourced desk covers the core booking line out-of-hours and at peak, since every fare depends on it. For hackney, the desk covers the pre-booked and account work — the calls you can't afford to miss even when cabs are out working the rank. In both cases the desk works inside your software, books in your name, and leaves your licensing entirely with you.
- Private hire: cover the core booking line, out-of-hours and overflow
- Hackney: cover pre-booked, hotel, and account work by phone
- Both: book inside your software, in your firm's name
- Both: licensing stays with you
