My 2p worth, in no particular order:
I don't remember *ever* having to answer a question on the lines of: "has the car ever been written off", when buying car insurance.
If the insurer *does* ask, and insures you anyway - you have an expectation that the policy would be exactly the same as one for a car which has not been written off.
On a side note - if the insured buys the car back to repair, it's not been a "total loss" to the insurance co.
Insurers don't check VIC details, and they don't check points/claims when you apply - they are only checked at the point of claim - don't know why. mate who works for insurance says its data protection. I reckon that checking costs money, either in losing customers, or actually paying for a database check.
or just that they get your money and then refuse to pay out if you didn't tell them.
A formal complaint to the insurance company would be a good start - if they didn;t ask about write off, and you didn't know until they told you, then I don't think they can cancel your contract as technically you aren't in breach.
If nothing else, you might get a partial refund of your premium - take it all the way to the ombudsman, cos it'll cost the insurance co £800 for the referral, and if they know you'll do that, they'll figure it's cheaper to pay you off, or admit they've made a mistake (in which case, don't forget you can ask for "costs" of £18 an hour for writing letters'research + stationery, parking, petrol for visit to post office etc)
Be aware - there is a question on most comparison sites "have you ever had insurance cancelled or special restrictions applied?" which you will have to answer truthfully, and will inevitably bump your premium up
