I think we can all agree that insurance is an utter rip off and needs an enormous overhaul in terms of legislation. For something which is legally required to be entirely in the hands of the private sector, is guaranteed to be to the detriment of the general public.
Attempting to rationalise insurance quotes is a waste of time. I tried last year and did actually manage to speak to an underwriter directly, which was a minor miracle in itself! What he told me was utterly unbelievable. I honestly can't be bothered to go into the full details as it is incredibly long winded. But in a nutshell, in my particular case, fraud claims within a specific postcode area were the problem. It's a shame that the specific area happened to be 10 miles away and had I lived on the other side of the street, literally XX1 1XB vs XX1 1XC and less than 10 meters away...my quote would have been 75% lower. My area is semi-rural, minimal crime, the area concerning high instances of fraud is metropolitan and high crime, yet it mattered not.
Prime example, among many, of why regulation is needed.
