A good insurer should be able to help, but yes, in general increasing your excess should help, also, if you do lower than average miles then again if you limit the mileage that will help. For younger drivers, you can also get a restrictor to stop the car being used at night which significantly helps. Have you checked that they have your employment status correct? The difference between 2 similar sounding job titles can be quite significant. Can you keep your car parked off the road when you are at home? Have you used one or more of the insurance comparison sites. I am sure there is a guide to getting a better deal on the moneysaving expert website too.
