Over the years I have had every position in the company, I used to put down I was a window cleaner but found insurance to be cheaper if your position in the company is more office based.
As in director/company sec, maybe they view you as more responsible.
My vehicle insurance has been as high as £2500 and am currently paying just on £1000, with position of director
My daughter is 20 an in uni, passed her test 2 years ago but I wasn't prepared to pay £4000 for her to drive, in November I was messing about on insurance comparison sites, entered my daughters detail, puts down that she was a post graduate, only on a fiat 500 .........
Quote came back at £996 ........ On 64 plate
So rang insurance up to double check and yes that was right, to my amazement, policy is in her name with no 'no claims bonus'
So car and insurance paid for the year for Xmas.
Point being it defiantly makes a difference to your quote depending on your job description.
