Asked BG to send an engineer to check if so-called meter tails, the cables joining a smart meter and a fuse box, are safe to use because they are old and we are not renovating the property. Took more than hour and several advisors just to send a query. The result? A rude and unprofessional engineer arrived to the site to exchange my elec and gas (!!!!) meters because they are faulty (????). Not even looking at the cables, the engineer simply lied to both me and his manager that they are safe. BG offered me to book a commercial, charged for appointment, because they can't confirm that the meter tails that they said are safe are safe indeed. Yes, it all sounds ridiculous, and so does BG. The worst thing is that I can't find a decent company to do the job, because the cables between a meter and a fuse box are considered to be an energy supplier property and the works aren't contestable.
