Thanks for the replies. I don’t have it in writing. The builder who completed the works also had his approval however I doubt that would stand for much.
My gut feeling is to move it.
C,D and E I’m afraid.
Possibly also a G) Swindler
I know that he replaced the fence during the conveyance as another neighbour informed me when I first checked the house out after the sale. However I have no way of proving it. I also don’t know if this alleged movement of the fence has caused the guttering to go over slightly before I started my works. As aforementioned, it wasn’t something picked up during the conveyance and the previous owner has dementia. I have pictures of the guttering immediately before and after the renovation.
