Protected No Claims Discount (NCD) is an optional add-on to your car insurance policy that safeguards your accumulated no-claims discount, even if you are at fault for an accident. Typically, building a year of claim-free driving earns you a discount on your premium, which can increase annually up to a maximum, often around 70-80%. Without protection, making an at-fault claim usually causes you to lose several years of discount, leading to a significant premium increase. The protection feature prevents this reset, allowing you to retain your hard-earned discount level after a single at-fault claim.
It's crucial to understand that protecting your NCD does not prevent your overall premium from increasing after a claim. Insurers may still raise your base rate because you are now considered a higher risk; you just won't lose the percentage discount you've accrued. This feature is usually offered to drivers who have already built up a substantial NCD, typically four or five years.
The following table illustrates a typical No Claims Discount scale and the potential financial impact of protecting it, assuming an annual base premium of $1,200.
| Years of Claim-Free Driving | Typical NCD (%) | Standard Premium | Premium After an At-Fault Claim (NCD Reset to 0-1 Year) | Premium After an At-Fault Claim (With Protected NCD) |
|---|---|---|---|---|
| 1 Year | 20-30% | $960 | ~$1,200 | N/A (Usually not eligible) |
| 3 Years | 40-50% | $660 | ~$1,200 | ~$660 (plus a possible base rate increase) |
| 5+ Years (Max) | 60-80% | $360 | ~$1,200 | ~$360 (plus a possible base rate increase) |
Eligibility rules vary by insurer. Some companies allow one at-fault claim per year without losing the protected status, while others may have stricter limits. Always check your policy documents for specific terms. For most drivers with a long claim-free history, the relatively small annual cost of adding NCD protection is a worthwhile investment against the risk of a much larger future premium hike.

Think of it as a safety net for your good driving record. You spend years building up a discount for not having accidents. If you cause a crash, that discount usually gets slashed, and your insurance cost skyrockets. Protected no claims means you get to keep that discount even after your first at-fault accident. Your bill might still go up a bit, but not nearly as much as it would without the protection. It's peace of mind for a few extra bucks a year.
