Moving a drain for an extension is more common than you might think, yet it is important to understand the regulations surrounding the job if you want to ensure not only that you won't be breaking any rules by carrying out the work, but also that the structural integrity of your new structure is not negatively affected.
While building an extension won't always affect your drains, there are instances where building out from the existing house will mean the new structure sits over a drain or manhole cover. In this case, it will be necessary to notify Building Control or your local water authority, depending on the type of drain you are dealing with.
