there are so many factors to consider, such as postcode (do other drivers in your bit of the world claim a lot) the car you drive, your age, your mileage etc… so when you say, I’ve done nothing and my premium has gone up, you have got older and driving an older car, doing a job that other heavy claimants do for a living….
Is the cost of insurance a shocker, yes it is but the personal accident premiums are fuelling the rises, go and look at the claims technical ratios to see how relatively small the margins are for the insurers (technical ratio is the premium plus the investment, minus the business operating costs minus the claim payout)
with the blackbox recorders that are being rolled out (to the young first but it’ll extend) the accident blackspot data will be built up and then it will probably start to be used as another underwriting consideration – I’m really not looking forward to the over 25s having the boxes forced on them because I only use my car in the evenings, although the super low mileage will offset it…
