OK. I work for UKI, they underwrite Direct line. They also do the same for Tesco, Churchill, Privilege, Lloyds TSB, Prudential.....it goes on, we're a massive company. We're also, in turn, owned by the RBS so penny-pinching is in full flow at the minute.
I'll get the easy stuff out of the way first.
Wheels affecting price. When we add aloy wheels on to our system it gives a couple of options.
1. Non-standard alloy wheels fitted to a new car. This doesn't affect the premium as they are fitted by the manufacturer, they're the size the manufacturer specifies for the vehicle, so they are an optional extra. It's pretty much the same as before, just a prettier wheel.
2. Non-standard alloys fitted to a used car. Now, this is why it rates differently. The car's speed is taken from each revolution of the flywheel. It will know, by the amount of rpm's the flywheel is doing, how fast your car is going on lets say a 17inch set of wheels. using the distance the wheel is travellimg, over time, gives you the speed. Simple, basic physics. Now, If you have 19inch wheels fitted as a mod, for each full rotation of the wheel, the car is travelling further, now it might only be a few inches, but when you're heading over 70mph, the distances start to add up. Now the flywheel always rotates the same distance, but your car is travelling further. Simply put, your speedo is out. You are travelling faster than you believe. This can increase the likelyhood of accidents whilst going around corners & with pedestrians. it sounds far fetched but this is the way they assess it.
Windown tints bringing the price down. The window tints, as they're classing them as a modification, will add an extra xs to the policy. The higher the xs, the lower the premium. That's why you'll see a decrease in premium.
