IMaybe one day they way the premiums are calculated will be transparent enough for you to see where the money goes, although I am probably dreaming there.
Under FSA regulations Insurance companies must tell you how your money is being allocated, we
always have to state how much our admin fees are, how much you are paying for any add ons (agreed value, breakdown etc), how much interest you pay for instalments etc.
I think all insurance companys have a lottery style machine that spits out random amounts.
Most insurers will have their own target market so yeah you could phone 20 different brokers and get 20 wildly different quote, they could even all be underwritten by the same company! This is because brokers such as us are given different rates from underwriters based on what they specialise in (age type of car/age of driver etc), how big their account is (ie how much business they place with that underwriter), how profitable their account is (premium income v claims paid) etc etc.
The data must be the same for all of the insurance companies about area, crime rates and car specs etc
Different companies will base a lot of stuff on their
own claims statistics etc so although there are often trends it is not necessarily the same accross the market. Also although most companies will use the same scale for grouping vehicles there are other factors eg we give target vehicle discounts on certain vehicles we specialise in and loadings on cars that have performed badly with claims etc so if you call for quotes on 2 cars that are the same group/value etc it still does not mean you will get the same price.
the only real variable is YOU,
This is to some extent very true though, as an insurance broker i often get the line "but my mate only pays £xxx" which is a bit of a nightmare cos so many people compare in this way even though its largly irrelevant. There are so many variables like occupation, how long driving, claims/conviction, annual mileage, experience etc that insurers will often take into account so its very unlikly that if you are the same age as a mate and drive a similar car that you will get the same quote.
dunno about the ginger people thing....
I could probably sit here all day and type about all the different stuff insurers look at but it would soon become very boring but i hope that it least goes some way to explaining it.
