When I first got my car 115 tdi, i bought it February and accidently bought a 9 month policy , quick NCB build up for young drivers but I crashed so kind of didn't matter!
But anyways, I have my birthday in June and renew in November, can't wait until this November now I'm 21 and have 1 years NCB! it opens up a whole new can of worm of insurance companies.
So what I'm trying to say it maybe buy a short term policy to fit around your birthday?
