To be fair, I think the "intending" arises because the requirement is (as per the rest of the sentence) that the person 'notifies' a building control body, and obtains their permission to go ahead, before the work commences. So, to use BAS language, they would be 'lying' if they said that they were 'carrying out the work' before the work had started!Yes. Is it not even less clear when the actual words from the Building Regulation (not guidance) are used? "A person intending to carry out work".
