Hi, Hoping for some suggestions/advice please. All help appreciated. Strap in... I live in a 2 bed apartment. There is 1 neighbour upstairs. My energy usage is steady and low. I spend 6/7 nights away per month. This week I submitted a reading from my gas meter. It was massive: over 400 units since my reading a month previously. (Equivalent, my statement tells me, to 16 quid a day.) It's simply not the case Since I submitted that reading I've been taking daily readings and it appears to be back to normal, having used 2 units over 4 days. My supplier, Bulb, are confident that the meter is mine, although they do recognise the huge jump. My neighbour above moved in around March. I know they have had problems with their supplier, EDF, who apparently don't recognise that there are 2 properties in the building. (Mine is Number 1, theres Number 3.) I don't think they've been using my supply or that the meters are crossed. I might be being simple here but a pipe from my meter goes into my apartment, while a pipe from their meter goes into theirs. When I turned my gas off, my hobs/heating stopped working. Theirs didn't. I'm convinced it's something to do with their ongoing problems with EDF and have a feeling I've somehow been lumbered with their usage. Bulb assure me that no other property is linked to my meter. I'm flummoxed and would be grateful for any suggestions/ideas/theories please. Incidentally, our electric meters were crossed, something I discovered after 7 years of paying someone elses bill. Ta very much!
