If your car or WAV is on a three-year lease, it will need an MOT test certificate roughly two months before the end of your lease If you’re interested in extending your lease, you’ll still need an MOT done within the last three months of your original end date and before you hand your vehicle back or extend your lease.
So you have plenyty of time before you hand back your car. When your car is in for its MOT you can either wait or Motability will provide you with a taxi back and forth or a freind or family can do it if you put them on the insurance. There is also a possibility you will be allowed to take it Krapfit if you asked Motability.
