my mates started a loft conversion before xmas and had the building inspector out to tell him he could start the job, he s now aware of part p and was right for getting a spark out who is in the prosses of getting registered, my mate was gonna do it himself until he found out about part p off me, goin off what ive read. the building inspector came today and says because the job started before jan 1st he doesnt need it, but i thought it needed to be finished by the end of march. now hes thinking he can do it himself, has the inspector made a mistake or can he go ahead and do it.
