I had neighbours report me to EH once over noise. I lived in a detached bungalow, had a 3 year old who was at nursery all day whilst I was at work, and was in bed for 7pm every night. They said my dog barked "all the time" so I willingly let the council install sound monitoring equipment; she barked, on average, twice a day, between 9 and 3, for no more than 30 seconds at a time, and always coinciding with the postie or people leaflet dropping.
They then complained about me standing outside smoking! Our houses were about 20ft apart, divided by a 7ft fence, and I had one ciggy in the morning before ds got up and a couple in the evening.
They complained about me starting the car up before 9am. I had to leave the house at 8.45 to get to work, and couldn't quite work out how I was supposed to get the car off the drive without starting the engine.
They rang my landlord and complained about dog mess in my garden. He came round as he only lived round the corner, saw one errant turd and told them to get a grip!! Likewise when they complained to him about noise from the repair work to the roof that he had arranged to have done!
They told the neighbours the other side that they suspected I was "on the game" as I'd had three different men round in a week. I overheard this conversation as my window was opened and I'm afraid I went batshit crazy at them! One of the men was my sons father, one was a mate from work and the other was my bloody dad!
I threatened to call the police and report them for harassment and deformation of character if they didn't pack it in. I moved shortly after, as I'd had enough and wasn't enjoying living in the house anymore :(
