snobeaver: Thank you Coyote.
I understood this was a community forum which would provide some helpful and informed advice on my query rather than a lecture. Perhaps the tone of your response is the product of some form of personality trait, or you view insurance fraud in a dim light.
However, I have already discussed the accident on the bike with the car insurer and they have told me that it was not necessary to declare the fault and would not have an impact on my car insurance in either premium or loss of NCD.
I'm not too sure what your problem is here? I wasn't lecturing you at all, I was answering your query! As BestAdvice has said, you have taken the appropriate action and informed your insurer or the intermediary. They are, in fact, giving you the wrong answer there as it is a material fact that will affect the decision of a prudent underwriter, without a shadow of a doubt. If your case was referred to an Underwriter for their consideration and this came back as 'okay' then this should clearly be noted before the policy incepted. An agent over the telephone would not have the authority to make such a decision without referral.
If I were you, I would get them to give you this in writing or provide you with the recorded telephone call in case a claim arises later on in the insurable period.
Apologies if you took my reply the wrong way but there's no need to be insulting to the person taking time out to help you. I think, perhaps, you should consider the tone of your response and your own 'personality trait' before you make assumptions.
