after i passed my test i upgraded to a 250, i cancelled my 125 policy, my 250 insurance was something like £10 cheaper then the 125 policy, i then around 8-9 months later decided to upgrade to a restricted 500, cost me an extra £70 to change the policy, for the remaining few months and then for this last year the policy dropped and have stayed with the same company.

Have a look around for insurance, i'm with quickfit, who are a brokers, but http://www.wickedquotes.com/ offer me the cheapest insurance apart from the company i'm currently with.

although no claims may give you a discount with that company, you may be better off shopping around every year.
