They will also write off when there is damage to the main structure of the chassis as it can't legally be repaired, but it doesn't sound like it's the case.

I'm more concerned at the one year wait on repairs through your insurer? Is that even with them organist g the repairs? The longest I've ever had to wait is two weeks and I was pit out that it took so long.

Its normal for them not to pay til after they usually pay the repairer directly
