Answer in brief

Rates fall at 19 (often the biggest single drop if licensed at 16, as inexperience ends), again at 21, and significantly at 25 when most insurers move drivers to adult bands. A clean record is the condition; one at-fault accident adds a three-year surcharge that offsets a year or two of decreases.
