Our neighbours informed us a month ago of their plan to convert their loft which is fine by us. However, the scaffolding has now gone up and we have not been given a party wall agreement to sign. My husband says he has looked online and says there is nothing we can do about it. I’m just worried if our house gets damaged. When our loft was done, the company took control of all of that for us so it makes me wonder who they are going to be using. Do we need one before they begin or is it more a case of let them know if we have issues?
