*grins* you forgot to mention charming :p
For anyone reading the thread wanting the same information - here's what I found out:
I phoned the Association of British Insurers to see what it thinks its members would be likely to do.
The spokesman said that it depends. There's no "insurance blacklist", unless the fraud was an insurance claim. You may have to pay higher premiums and - particularly because it was fraud - you may find many insurers won't cover you.
I recommend phoning round a few to discuss your specific details in a bit more depth.
One thing the ABI were really adamant about is that you should absolutely disclose your prior conviction to the insurer. Otherwise, they could potentially refuse a future claim because you hadn't informed them.
I also recommend getting in touch with a charity such as Unlock - they have campaigned about this and can provide details of insurers who may cover you.
Best of luck - I can appreciate it must be upsetting to be preventing your husband protecting his possessions. Please do let me know how you get on.
