Also bear in mind that the meaning of full NCD protection may vary between insurers.There is no single meaning to this term across the industry. For example, protection may apply up to a certain claims amount limit (ie €5000), or type of claim, or number of claims in a certain period. And some insurers apply a "step back" ncd if their particular criteria is exceeded. For example, from 50% to 20 or 30% or whatever or alternatively you may lose the full NCD. Regarding type of claims, some insurers allow full NCD protection regarding fire or theft claims regardless of number and amounts of claims where fault is not generally an issue. However, its worth bearing in mind that insurers may view a large number of claims as a reason to apply special terms at the next renewal. Similar to house insurers exlcuding water damage when there is potentially a future higher risk of claims. In short, there is no completely clear distinction that applies across the board, and you should establish the terms applicable to full NCD protection. Insurers use this feature as a selling point, and I'm not saying they are wrong to do this, but you do need to know what they mean by it.
