We all know that no one, LBCs included, is going to give a flying about EICs until there is a fatality or other very serious incident at the property in question. It's all about a signature to pin the blame on.
Living in the rural area that I do, a good proportion of the work I have done is on jobs where no planning permission has been applied for, with the home owner preferring to rely on the soon to be abolished 'four year rule' instead, so it wouldn't go down too well if I submitted paperwork to the authorities.
