The hardest taxi job to find is not the airport run or the wedding. It is the one that has to happen at 8.10 every weekday morning, term after term, with a nine-year-old in the back who will notice if it is a different driver.
A regular run is valuable to a taxi office because it is predictable work in a trade that is otherwise built on peaks and troughs. In return for that certainty, a good firm will allocate a named driver or a small pool of two or three, agree a monthly price rather than a per-journey fare, and put the booking on the system as a standing order so nobody has to phone in each night.
Not every office is set up for it. Some are geared entirely to on-demand work and will treat your Monday morning as just another job in the queue. So the first question to ask is simply whether they do contract or account work, and how many regular school runs they already have on the books.
Every licensed taxi and private hire driver in Britain has passed an enhanced criminal record check as part of getting the licence from the council. That is the floor, not the ceiling. For a school run you are entitled to ask more: whether the driver holds any additional safeguarding training, whether the firm does home-to-school contract work for the local authority, which comes with its own vetting, and what happens when the usual driver is off.
The last point is the one families forget. A firm doing this well will introduce the back-up driver in advance, not send a stranger on the morning the regular is ill. Ask them to.
Most offices will quote a school run as a weekly or monthly figure, sometimes with a discount for paying by standing order. Agree what happens on inset days, during half term, and when the child is off sick with an hour's notice. Some firms charge a reduced cancellation fee, some waive it entirely for account customers, some expect the full fare if the driver has already set off. None of those is unreasonable, but you want it in writing before term starts rather than argued over in week three.
Picture two children at different schools a mile apart. One firm might send one car and do both drops in sequence. Another might price it as two jobs. The first is cheaper and usually better for the children, but only if the timings work. Give the office both school start times and let them plan the route.
Treat the first two weeks as a test. Note whether the car arrives within the agreed window, whether it is the driver you were introduced to, and whether the office rings ahead when anything changes. A firm that gets those right in September will still be getting them right in July.
The listings on this site show which of the 2,635 taxi companies cover your area, and many state plainly that they take contract, account and school work. Start by browsing firms near the school rather than near home, since the drop-off end is where timing matters most, or describe the weekly run and ask for a monthly price from several offices.
Before you sign anything, ask for the back-up driver's name and the cancellation terms in the same email. Those two lines are what you will need at 7.45 on a Tuesday in November.
