You won't get any written information about the first MOT which in your case will be due in March 2020. You must have your V5 with you, your current insurance certificate and you may need a 'green card' issued by your insurance company proving that your insurance covers your vehicle in whichever country you are visiting. It's free (usually). I said, may need, as it will depend if we are still in the EU or not. If not, you will also need an international driving permit, which lasts for 12 months, and can be obtained from your local main post office. That costs about £5.
