. At the end of the process, I was asked whether I wanted to protect my no-claims history. I have never heard of this or known how much no-claims bonus I have on any insurance. Is it worth doing?: The principle of no-claims bonuses or discounts is simple: when you go a full year without claiming, your insurer rewards you with a discount on next year’s premium. For each claims-free year after that, you get a bigger annual discount. This doesn’t keep increasing forever, though.
Like premiums, NCDs tend to be revised each year. So even assuming you maintain a claims-free record, you won’t be able to predict your future discount, or how yours compares with other customers with the same number of claims-free years.
