I live in a new build. Moved in around 3 years. My neighbours have moved their heat pump to the side of their house next to my boundary in the side alley. It’s a bit annoying as it’s very loud as in a funnel. Before it was on the other side of their house, where the developers installed it I never heard it. Is there anything I can do about this? I don’t want to upset them but it’s pretty annoying tbh.
