If your claim is settled as fault then your No Claims Discount will sadly be reduced. Don't worry though, you won't lose all the years you have built up! For your first fault claim, you will lose only 2 years of NCD (unless you have more than 5 years NCD then it will fall to 3 years after your first claim).
If your claim is settled as non-fault, your NCD won't be affected 😊
What happens if I have NCD protection?
If you have purchased NCD protection, you can make one (or more) fault claims before your number of No Claims Discount is stepped down.
