In my experience, the insurance company likes the car to be registered in your name, not the company's. This way it is simpler to take out a personal policy instead of an expensive company policy and maintain your no-claims discount. Also, legally, the car is not a pool car, so it should be registered to the individual.
The registered keeper on the V5 certificate is not the leagl owner.
My LV insurance policy is worded such that I am the registered keeper and the car is owned by a company.
As discussed above, Tesla by default put the company name on the V5 which is a real PITA, even when an indivicual is listed in the registration detais on the web page. I learned this the hard way in 2019 when I got my M3 then, I changed the keeper but then DVLA listed it as a change of keeper on the V5, which is less than ideal because that is misleading.
Not wanting to fall into this trap again when I collected my M3 LR last week, I phoned Tesla a week befopre delivery and told them I wanted to be the registered keeper, to which they wanted an email request to that effect, which I supplied.
This is how my order page looked a week before delivery:

For those ordering company cars, check you get the REGISTER PERSONALLY bit on the order page if you want your name on the V5.
I haven't received my V5 yet though so not certain this has worked, but looks promising from the registration application in my account.
