Check the paper work but it seems that by default they haven't re enrolled you in the protected NCB scheme. For what it's worth and also for future reference NCB protected or otherwise does not work how you think. For the sake of this explanation let's assume your base premium is £100 and you get full NCB of 70% so you pay £30 yes? ok let's assume for another £5 you can protect that NCB, so you are paying £35. Now the £5 is what is known as re-insurance basically you are paying £5 to cover the difference between the £100 and the £30, still with me? Right so if there is a claim, they will reduce your NCB let's say by £30 so now you have to pay £70 rather than £30. The £5 reinsurance will cover the difference between £30 and £70 so now you pay £30 premium still, yes......that's where most stop listening! Now you have claimed you premium has gone up by £10 and now your NCB premium has gone up top because you have claimed so now the total premium is £117. So you'll have to pay £47 now even with NCB protection. Believe me unless it's a lot never claim, they get it back in the end.
