My tenancy agreement states that I can not smoke however it goes into specifics on this "no cigarettes, no pipes and no cigars" it did not list vaping / e-cigs of any kind. From the start of my tenancy there has been this fishy + burning smell whenever the shower is running. I have tried to get them to fix this since last October with no joy. The next door neighbour had called my letting agency furious claiming that her house smelled of smoke constantly. We found out today after hiring our own electrician that the fuse box was from the 1970s and was literally burnt to a crisp due to running heating up every time the shower was running. The landlord has now also confirmed this with their own electrician. However, landlord has stated that a vape was located in my house (not being used in the house, just on the kitchen counter, it's not like they smell like smoke anyway) and has found references in my social media to vaping. They are pushing on the vaping being against the no smoking rule after now being caught renting out a property that doesn't meet electrical safety regulations. Threats of eviction stating that my neighbours complained for many months and they will need to have the house deep cleaned, I will lose my deposit over this etc, etc. I dont know legally where i stand on this at all. Help would be much appreciated so thank you in advance.
