What is meant by ‘no-claims bonus’ NCB? How high can this bonus go?

The no-claims bonus (NCB) is a special discount that you get on your bus insurance policy for not making any claims in a given policy year. This discount is generally given on the bus insurance premium. The no-claims discount on the premium can go as high as 50% and save you a lot of money. You can also opt for the NCB Protector to protect your claim-free streak.
