App needs to be on at all times. Can’t afford for your phone to go off, and you can’t put it in airplane mode. Same for turning off Bluetooth, they want it on 24/7. Was threatened of a policy cancellation about halfway through my policy due to these factors, but the lady I spoke to regarding this managed to withdraw the cancellation as I was not aware putting my phone in low power mode also affected the use of the app. Very hard to get ‘green’ driving scores every week if you do long journeys or drive at night. Not to mention your policy can be cancelled if you have 4 red weeks ( or 2 consecutive red weeks). Drifting over the speed limit, especially on motorway journeys guarantees a red score. Also very long waiting times for phone calls and long email replies as others mentioned. My policy expires next week, but I am renewing with another insurer without blackbox, as i don’t think the hassle is worth the saving you get. I somewhat regret even starting out my driving experience with carrot if I knew it was going to be this flawed. Would advise anyone to use a different insurer, ideally non black box as a lot of people take out black box insurance without knowing what’s in store. For those who can only afford insurance with a black box, there must be other insurance providers who provide a better service than carrot, even if it’s marginally a bit more expensive.
