Im 19 years old and currently a student. I am looking to purchase a motorbike, but will probably buy a scooter instead since its cheaper and easier to get used to and ride.

But the problem is, im not sure how insurance works on scooters as well as the legalities of actually riding them.

So where could I get my scooter insured, on average how much would it cost, do I need any licences or lessons, etc…?

Help!
p.s. I live in the UK And lets just say its a scooter, not a motorbike
