It sounds like you rang your Car Insurer about the incident, they advised you it was not covered and they entered it as an incident on the Claims and Underwriting Exchange (CLUE).

I would ask the home Insurers for a covering letter confirming the incident was paid by them and giving a brief outline of the incident.

You can then send this to your motorcycle Insurers so they can see the issue.

I would also recommend you go back to your car insurers and explain the situation and forward them a copy of the letter. The initial level of customer services may try and palm you off as it will almost certainly be something they've never seen. If you remain polite and persist you should get through to someone who can help. Basically you want them to adjust the incident on CLUE to remove it.

If you have no luck with the car Insurers send a polite and concise letter headed "Official Complaint" along with a copy of the letter which should get them to remove the entry on CLUE.

Ideally you want the CLUE record cleared as it may cause other problems in the future.

You can obtain a copy of the data CLUE hold about you for a fee of £10.

The law changed recently regarding non disclosure so this should not affect your theft claim unless you have other claims or convictions.

Looks like common sense has finally been applied.

Since its not in any guide books I suggest you start looking to see if there are any bikes of the same model/age for sale and use that price when you bargain.
