Selling an old terraced house and what a Surveyor's Report might mean

I am in the process of selling an old terraced house, an offer has been made and I have accepted it. I assume the next stage will be the potential buyer will have a Surveyor's Report done on it. This was my family home and I used to live in it with my parents many years ago. I am just wondering how I would find out whether the property has had a damp proof course done on it ie I cannot remember if my parents had one done and if so where the paperwork would be. Is there any way I can find this out? is there someone I could contact that would hold such information? Advice is much appreciated. Thanks
