In the event of an accident you may need to provide evidence that you are the main driver, on an annual basis - so keep records of when your daughter is away from home and the mileages at those dates.

Realise that when she passes her test, the premium is likely to go up not down - as she's no longer being supervised.

You bought the car and at this point in time you are the registered keeper and its on your drive. Your daughter is at Uni thus presumably not living at the same address.

She's not living at the same address in term time, but is living here during Holidays.

Cannot see a problem myself.

Perhaps I'm being over-cautious and a bit cynical, but I'd rather be safe than sorry.

Whatever action you take Pondlife, you need to do it quickly. Unless, of course the vehicle has been "SORNed"

If it is not subject to a SORN, then It sound like you are in breach of the Continuous Insurance Enforcement regulations that came into force in June 2011, and could result in a Fixed Penalty or a fine against the Registered Keeper.

If there's a claim and insurer make inquiries about main user then all circs will be explored. Fact that you have another car (the one with the new car as a temp additional) will give rise to additional questions.

You may actually find it's no more costly to insure with daughter as main driver and you as additional.

Have you considered disscussing your concerns directly with the insurance co?......or am I thinking too hard?

Thinking too hard - much too simple to ask an insurance companies advice. Very odd suggestion ;-)
