As long as the lease payments don't impact upon your normal IVA payments and you can get a company to agree to lease a vehicle there should be no problem. You will need to discuss this with your IP, however.
My opinions are merely that .. opinions based on experience. Always seek professional advice.

Hi I got a lease car through a scheme by my employer. It was a god send. I don't think I would have got one through a normal company. The car was agreed by ip as long as payments met. It was a struggle but better than the daily worry of the car x
