I thought it was about time to look at Kabbee as well. Please note that I have never used Kabbee so I am not personally recommending these services. I do use Uber, Gett (was GetTaxi) and Hailo on a regular basis and am very happy with them.
£5 Kabbee sign-up code – valid until the end of December 2015!
Whilst Uber, Gett and Hailo do a great job of finding you a vehicle in Central London, they are less useful in the suburbs.
Kabbee works with 70 individual minicab firms across London, giving total access to 10,000 vehicles. The navigation system is the same as Uber or Gett, allowing you to track your car as it approaches.
The iOS app is here, the Android app is here. It is also available for Blackberry 10 and Windows Phone 8. If you don’t have a smartphone, you can also create an account and book via their website, just like the old days.
Kabbee discount code [deleted as now expired] will give you a £5 bonus in your account when you register via the app or the website. This code is valid until 30th November 2015 and is exclusive to Head for Points.
Kabbee is quite tough on its rules and the codes expire after two weeks after registering them. The minimum ride to use the bonus is £10.01. You will be told your fare before you confirm your booking so you can be certain that the ride is over £10.01 before ordering the car.
Kabbee has some particularly attractive fixed price deals for London airport trips which are worth a look.
