UK van insurance providers typically group vans into five main categories, which they use as a starting point for calculating your premium:
Car-derived vans – Vans based on passenger cars, like the Vauxhall Astravan 
Micro vans – Compact vans for small deliveries, like the Citroën Nemo 
Small/light vans – Vans with a raised rear, e.g. Volkswagen Caddy 
Medium/panel vans – Versatile vans with high capacity, e.g. Ford Transit 
Large vans – Big vans with double rear axles, like the Luton van 
Other factors that affect your quote:
Engine size & fuel type 
Manual vs. automatic transmission 
Security features like alarms 
We hope this helps you understand how your van is classified and why your quote may vary!
