To be eligible for the Motability Scheme, you must receive either:
You need to have at least 12 months award length remaining when you apply. An application for a car can also be made on behalf of a child aged three or older, who is entitled to the mobility allowance. Even if you don't drive, but receive the allowance, you can apply for a car as a passenger and propose two other people as your drivers.
If you are under 65 and have a disability but are not currently receiving the Higher Rate Mobility Component of the DLA you may be entitled to this allowance. Contact Motability to find out about possible options.
