Aaah, I see - I beleive that the insurers will all continue to protect your discount. At the worst case though, you could always stick to your current insurers if everyone else is expensive.
I know what you mean though - insurance does tend to be a rip off. I have 3yrs no claims on bike - when I first insured they would take into account my cars no claims bonus - however if I were to make a claim on my cars insurance, my bike insurance would go up to....mad!
Maybe it is worth filling in an on line form once saying that you have 7 years no claims, and second time saying you have 7 years no claims but an accident in last year?
Might get around to it later on tesco.com
if you get a chance try it and we will compare results
