Just to clarify - if you insure your house to a value of €300k and it burns down, the insurers won't give you a cheque for €300k, even if you can show receipts showing that it cost that amount to build in the first place.
They will demolish and clear out the site. Then they will build you a new house of similar spec but it will be build to modern standards with all checks, professionals and whatnot included. They will cover the cost of all this UP TO* the insured amount.
This is why it is very important to state your square footage and follow their advice on how much to insure for. An then you should go a bit over that to be on the safe side**.
*If they can get it done for less you won't see the difference. Their job is to put you back to where you were before the loss.
** There'll be relatively little premium difference between insuring a gaff for €300k or €350k
Great Post.
Had to add an extra 20k potential rebuild cost to my insurance this year
