i've just got my renwal through, to find that my insurance has doubled since last year, i haven't made any claims or got any convictions, and have 9 years no claims .........what i can't understand is how my premium can double when nothing on my policy has changed, my premium for a year is now more than what my car is worth. i have also tried changing my post code on price comparison websites to see the difference it makes. if i park my car on the roadside at night, 2 roads away from my house the quotes are halved. as it falls into a different postcode area................how can they justify this when it is only a few hundred metres difference ???? last year i was paying £680 for fully comp, my renewal price is £1360. if i continue to park my car at my home address overnight. if i park it 2 roads away at night, i have been quoted £543.
