I have agreed value insurance with as been typed a re-evaluation required by the insurer every two years. I am not one for reading insurance documents, though I did note that when out of the UK it is possible that some policies drop to the minimum level of cover required by THAT country.... which came as a bit of a shock for one expecting to be covered fully comp with agreed value...?

Also looking at simple repair costs I suspect insurance write off`s may becoming more common..? No facts to back this up, just guessing.
