Kabbee is a new online cab booking service, also available via an iphone or android app, that lets you book properly licensed cabs in London at the best available prices.
Although it has clear overlaps with the likes of Uber and Hailo, one of the unique selling points of Kabbee is that it’s not simply a taxi booking service. In fact, when you make a journey request with it, Kabbee, it will instantly compare over 70 cab fleets across London, allowing you to book by car type, price, arrival time, on-time rate and user rating.
Equally interestingly for the value traveller, you can get £10 free taxi credit by signing up to Kabbee here, and adding the promotional code ULG3TL in the relevant box:
£10 of free taxi credit will certainly be enough to get you a short-ish trip without payment, and at worst a decent chunk off your journey. Given that you get the price beforehand, you will also know exactly how much of your journey will be covered by the free taxi credit.
An example of the app search result is here:
I have used Kabbee twice now with no issues, via the app. Booking is easy, the cab came exactly when it said it would, the payment (with free taxi credit on the first occasion) was straightforward and the cab was a standard black London taxi. I suggest you try them out at least once with your free credit and see how you go.
