Don't just stick to your current van insurance company because they've given you good deals in the past, it still pays to shop around as cheaper deals may be available.
You can reduce payments by offering a voluntary excess, but keep in mind not to offer a huge sum as you will need to meet it if you make a claim.
Always read the small print on your policy to see just what is and isn't covered.If you are unsure about anything ..ask!
Making a claim will not automatically lose you your no claims bonus. Most insurers will relegate you only two years meaning if you had 5 years no claims then you would still have 3 years.
