Not sure if anyone will be able to help but the situation is this:
OH has a company car which he is entitled to use for personal use too. He gets unlimited petrol. He is taxed on this as a benefit in kind.
Earlier this year we booked a trip which involves taking the car to Europe. OH's line manager had said this would be fine. Now the company has said he cannot do this (the leasing company is fine with it). Long shot perhaps but does anyone know the legalities of the company restricting the usage of the car when he's paying tax on it as a benefit?
