When you declare modifications, it’s important to study which parts of your self–build campervan qualify. You’ll want reassurance that the correct layers of protection will secure the full value of your self-converted vehicle, so your premiums need to acknowledge the value of any changes that you’ve made.
Not all changes will affect your premiums. Exterior paint, or smaller cabin accessories are unlikely to affect this. But major mechanical alterations to a vehicle, such as changes in suspension, will need to be declared.
