My husband is planning to start a courier service within the town. He has bought a van for this purpose. However, according to our friend Jeff, we should get a courier insurance rather than a van insurance. I am not much aware of such things. I searched courier insurance quotes here ( https://comparecourierinsurance.co.uk/ )  but these are little expensive as compared to single vehicle insurance. 

What do you say should we take vehicle insurance or courier insurance?
