Not always true jobs affect insurance quotes a lot
Yeah occupation can have a huge impact on the price as much as +/-30% in extreme cases. What TeddyKGB said is true to an extent, Police is a good occupation to have and will earn a discount with many underwriters but there are many others that are considered "low risk" and can lead to lower premium.
It is all based on risk assesment/claims stats etc and certain occupations statistically have many more claims hence have higher premiums.
Knowingly giving Insurers false or incomplete information is a
very bad idea and could land you in no end of trouble. You really dont wanna give an insurance company a reason to void your policy if you make a claim leaving you liable for all the costs and possibly beaing convicted of no insurance?
A mate of mine recently had a bit of bother for a fairly simple mistake, he told his insurers that he only used his car for social domestic & pleasure use ONLY (no commuting), was involved in an accident and on the claims form there was a question "what was the purpose of your journey?" he put going to work and the insurers although still dealt with the claim, made him pay the extra premium for the commuting to be added before they would.
