My partner has become aware that her name is being used as a named driver to lower someone else’s insurance costs. He does not have her permission and she will never drive the vehicle, so she contacted his insurance company by phone and was told "we can not discuss it because of the data protections act". So she wrote to them requesting her name be removed. She then phoned them again to be told "we have received your letter, your name is still on his insurance and we can not discuss it any further because of the data protections act".
Firstly is it legal to use any persons name as a named driver just to lower your own insurance?
And secondly is there any way she can get her name removed?
