NCD gives a discount off the premium, no more, no less.
The following figures are EXAMPLES only, I have no idea of the present figures applied by insurance companies.
Lets say your NCD entitles you to 40% discount, when your "risk" is assessed your premium could be set at £400, so you pay £240 (£400- 40%)
You have an accident, your "risk" increases, so your new premium is £500.
If you had lost your NCD you would pay £500
If your NCD was "protected" you still get 40% discount so you now pay £300 (£500-40%)
So, your "protected" NCD has "saved" you £200, even though your actual premium has risen £60.
What annoys me is that simply because someone hits me when stationary, MY risk is seen to have increased !!
or the latest stupidity, that the risk of the clit being in an accident has increased because it is a cat D car .... how can that change the risk of an accident
