Humming sound indoors is doing my head in
Neighbour in my flats had a smart meter fitted on Thursday last week, ever since I have been able to hear a constant low thrumming noise that is very annoying. I believe the sound is being caused by the new electric meter in the electric cupboard. His energy supplier are refusing to send an engineer out. My brother used to be a meter fitter and says that all that needs to happen is the screws fixing it to the board need loosening a quarter turn. Has anyone else ever encountered this or know of ways to solve it? I can't get into the meter as it has a fascia that needs removing. It is a landis gyr rectangular meter.
