Contacted Tesla 3 weeks before delivery as I was sorting insurance to ask who would be the registered keeper. my company was buying the vehicle but the online portal showed me as the keeper - fine. The agent I spoke to from Tesla (called Romain) said he thought it would be me personally. Fine. I said I was about to spend £750 on insurance so was he sure. He put me on hold, then came back to confirm that I personally would be the registered keeper. Fine.. I also emailed Tesla to ask for email confirmation after reading some of these posts...... but they never responded :-(. So, onwards, Insurance purchased before collecting the car assuming that Tesla (Romain) and the Online Portal must have been correct. Ah, but no! When the V5 came through, it had the company as registered keeper. Directline said the insurance would be declined if it was a company (even though they had previously said it would be fine) - I had to find another insurance company...... . Contacted Tesla again (3 times), eventually they sent me a letter to send to the DVLA that they said would change the registered keeper - but when the letter arrived (after chasing twice), it just had Care Of and specifically said the Company was still the registered keeper. So, I then had to cancel the DirectLine insurance and go with Admiral - they were OK with having a Company as Registered Keeper - also was £200 cheaper. A right pain in the arse, wasted hours of my life...... I didn't really mind what the answer to the original question was (me personally or Company), but the answer was wrong and I had fun waiting several times to get through to Tesla / Directline / Admiral.
On the plus side - I am in love with my Tesla Y...... a thing of beauty, power and brains! Who cares about the insurance cuffufle, just a hiccup !
