Put 2,635 taxi companies on one site and a shape starts to appear. Not a set of statistics, because a directory listing is not a survey, but a picture of how the trade is organised across the country and what each kind of firm is telling you in the few lines it has.
The first group is the hackney carriage operators: firms whose vehicles carry a council plate, work the ranks at stations and town centres, and run on the council's meter tariff. In larger towns these are often co-operatives or radio circuits, where owner-drivers pay a subscription to share a phone number and a controller. Their listings tend to mention the rank, the station, and the fact that they can be hailed. Many also take phone bookings, which blurs the line, but the plate is the thing that defines them.
The group most people will recognise is the private hire office: a licensed operator with a phone line, an app or both, taking pre-booked work and dispatching drivers who are licensed separately. These range from a family office with a handful of cars to regional firms with hundreds. Their listings talk about airport runs, account work, fixed fares and 24-hour cover. When you read 'minicab' in a listing, this is what it means.
Another cluster describes itself as chauffeur, executive or corporate travel. Legally these are still private hire operators, but the fleet is premium saloons, the pricing is hourly as often as per journey, and the language in the listing is about clients rather than fares. Wedding car specialists sit next to them, sometimes as the same firm.
At the other end are the operators running 8-seaters, 16-seaters and full coaches, for group travel, school contracts and events. Above eight passengers the licensing changes from private hire to a PSV operator's licence, and the listings usually say which side of that line the firm sits. Some private hire offices keep a minibus or two for airport groups and stag weekends. Dedicated coach operators are a different trade altogether.
Listings cluster where people are: around stations, hospitals, airports and town centres. Rural areas are thinner, and the firms that cover them often list several villages by name because their trade depends on being found for each one. Airport corridors have a pattern of their own, with firms based 20 or 30 miles out advertising fixed fares to the terminal, since a firm right next to the airport is competing against everyone.
Licensing is local, so a firm's area is drawn by the council that licensed it, and a private hire booking has to go through an operator licensed in that district. A listing that names its council and its licence number is telling you where it can legitimately work.
Look for the type first: hackney, private hire, chauffeur, minibus. Then the area, ideally named in terms of towns or postcodes rather than 'nationwide', which usually means the office will subcontract. Then the services: airport, contract, wheelchair-accessible vehicles, account work. Then the hours, since '24 hours' from a two-car office means a phone that is answered, not a car that is available. A listing that gives you all four in plain words is from a firm that knows its trade.
You can browse all the listed firms by area and read them with that checklist in mind, or put a specific journey out for quotes and let the firms that fit reply.
Start with the licence type and the named area. Those two lines tell you more than the rest of the listing put together.
