I tried to get a quote with my previous years smart miles score for this years car insurance but without the black box. They said they would put me through to someone to check that, got onto the phone with a man who said he would charge me ?25 to do a new quote, not understanding I was trying to use my previous smart miles score. I was either put through to the wrong people or they had no idea how to do that which seems a bit odd as of course people will want to take the black box off their car at some point. My insurance went up by ?350 also as I changed my address and I was not told until I had paid ?40 to change this how much the new renewal price would be because 'they could not tell me'. The smart miles box in general is not bad however if you wish to drive after 10pm (which is not unheard of around my old address as busses stop at 8pm and I would have to pick family up from work), prepare for your score to plummet. You can speed for an hour and your score would only go down slightly, drive 5 minutes past 10pm , you've lost about 60 on your 'driving at night' score and your overall will go down about about 10 points at least due to this. Some people have to drive after 10pm and if the scoring system should work with this then please do not chastise someones score so much due to this.
