Sometimes, depending what they are, they can reduce the premium. A signwritten van for instance costs less to insure than a blank white one because it's more likely it will be recovered if stolen.
Indeed.
I have a "modified" van, former railway crewbus, now a sort of mobile office thigie with a highly distinctive exterior paint job.
When insurance companies hunkered down after COVID, it became costly and difficult to insure via my usual insurer, so I went to an insurer that specialises in modified vans (and cars). I saved over £300 on the annual premium and have a better policy. Turns out there is a big modified vans scene just as there is for cars, and specialist insurers who cater for that market.
I guess they have figured that people who put time and money into modifying their car or van typically look after it. Certainly the lad at the end of the street who has a car he has modded extensively (and quite tastefully) is the most considerate younger driver in the street.... but then he owns the car (not on a finance package) and has spent hours getting it how he wants it.
Someone with a highly modified car may well have excellent (and cheaper than non-modified vehicle) insurance via a specialist. It's the ones with minor tweaks they don't realise are classed as "modifications" by insurers that are more likely to get caught out I suspect.
