<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>🎁 &#039;&#039;&#039;No claims bonus (NCB)&#039;&#039;&#039; is a reward mechanism embedded in many personal lines [[Definition:Insurance policy | insurance policies]] — most prominently [[Definition:Motor insurance | motor insurance]] — that grants the [[Definition:Policyholder | policyholder]] a progressively larger [[Definition:Premium | premium]] discount for each consecutive year in which no [[Definition:Claim | claim]] is made. Widely used in the United Kingdom, across Continental Europe, and in several Asian markets including Singapore and Hong Kong, the NCB serves as both a loyalty incentive and a behavioral signal that aligns the policyholder&#039;s interests with the insurer&#039;s goal of [[Definition:Loss ratio | loss ratio]] improvement. In some markets, the term is used interchangeably with [[Definition:No claims discount (NCD) | no claims discount (NCD)]], though certain jurisdictions draw subtle distinctions between the two.<br /> <br /> ⚙️ The mechanics are straightforward: each claim-free policy year earns the insured an additional tier of discount, which can accumulate over multiple years to a maximum level — often reaching 60% to 75% off the base premium in mature motor markets. If the policyholder files a claim, the NCB is typically reduced by a set number of steps, and rebuilding it requires further claim-free years. Many insurers offer an optional [[Definition:NCB protection | NCB protection]] add-on, allowing the insured to make one or two claims without losing accumulated bonus levels, in exchange for an additional premium charge. The exact scales, step-back rules, and protection options vary significantly by country and insurer, and some markets have developed centralized databases or [[Definition:Insurance bureau | industry bureaus]] that verify NCB entitlements when a policyholder switches carriers.<br /> <br /> 📈 Beyond its consumer-facing appeal, the NCB system provides insurers with a powerful [[Definition:Underwriting | underwriting]] and [[Definition:Pricing | pricing]] tool. A long NCB history signals lower expected [[Definition:Claims frequency | claims frequency]], enabling more refined [[Definition:Risk segmentation | risk segmentation]] without relying solely on demographic or vehicle-based rating factors. From a competitive standpoint, generous NCB scales can attract and retain low-risk policyholders, improving portfolio quality over time. However, the system also introduces [[Definition:Anti-selection | anti-selection]] risk: policyholders with high NCB levels may avoid filing legitimate small claims to protect their discount, which can distort loss data and complicate [[Definition:Reserving | reserving]] for [[Definition:Incurred but not reported (IBNR) | incurred but not reported]] liabilities.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:No claims discount (NCD)]]<br /> * [[Definition:Motor insurance]]<br /> * [[Definition:Claims frequency]]<br /> * [[Definition:Premium discount]]<br /> * [[Definition:Risk segmentation]]<br /> * [[Definition:NCB protection]]<br /> {{Div col end}}</div>
