The cost of van insurance in the UK can be influenced by several factors, including the type and age of the van, your driving history, and the level of coverage you choose. Additionally, where you park your van overnight, your estimated mileage, and whether it's used for business or personal purposes can also impact premiums. Adding security features like alarms or tracking devices may lower your costs. It's always a good idea to compare quotes from different insurers and consult an FCA-authorised provider for tailored advice.
