Thats it! Indemnity insurance.
But our solicitor involved building control and once there involved you can't have indemnity insurance. We are having to have the glass in one of our kitchen windows replaced with toughened glass under same ludicrous ruling they have, because the window is next to the back door.
Until the glass is replaced, we cant have the completion certificate for the miniscule kitchen extension that was built in 1998, which somehow never cropped up when we managed to buy the house in 2001.
