Taxi Services at Didcot

I've done this myself, many times. That late at night, I'd definitely pre-book; I've arrived at Didcot Parkway after 10pm on a freezing cold Sunday only to find no taxis outside and half an hour to wait even after phoning several companies. Other days, there's been a line of cabs waiting but it seems quite random.

The people I visit at Harwell usually book me with Pryors: https://pryors.co.uk/ Yes they have very nice cars and use words like "chauffeur driven Mercedes", but for a run like that you'll be on the meter and pay the same as any other taxi. They've never let me down and I'd recommend them whole-heartedly.

Further to the other answer, your hosts at Harwell may have a list of local cab companies they use and rely on. Taxi scams are rare in the UK; more common is them failing to turn up when booked, and making a habit of that tends to lose them big clients.

There is a taxi rank at Didcot Parkway. There have been occasions when none have been around at that time of night, but there is a good chance you'll find one right away. If not, the town has several reputable firms whose cars will tend to use this rank if they are available, but if not, their dispatch office is sure to be open for you to call. Booking ahead with one of them is probably prudent if you know when you will arrive.

Pryors is the biggest taxi company in Didcot. They're not the cheapest...but they're the ones with the poshest fleet (everything Mercedes). Their office is about ten minutes walk from Didcot Parkway station / a few minutes drive away. It's possibly worth booking with them (or another taxi company) if you can because at that time of an evening (depending what day of the week) the rank is often empty as the taxis are busy shifting people to or from various evening venues. But if you're not in a hurry, book them when you get there if the rank is empty.

My step son has run a cross a few dodgy individuals running taxi service in the area... they tend to put their prices up if they think they can get away with it (double the meter rate late at night... more if you're drunk). I've never heard any complaints about Pryors.

The taxi rank is to the right when you walk out of the station (if you walk out the main doors) or straight ahead if you go out the side door.

AFAIK Uber doesn't operate in Oxfordshire.

Another Didcot resident here. Pryors is a decent choice, but just for completeness there is also "Go Green Taxis" which are common sight in Didcot and online at http://www.gogreentaxisltd.co.uk/didcot-taxi-service/
