Wow your electricity prices are insanely cheap to me! I knew it was a bit more expensive here, but not by over 3x or even 30x based on your September estimate! We also have standing charges that amount to something like £250 a year even if you use no electricity whatsoever. My electricity & gas bill is over double yours for two people in a 2 bed house and we basically never use the heating. I think the economy of it makes sense with my situation but it definitely doesn't for you
If you don't mind me asking, where is it you live? Does your country have a lot of oil reserves or something?
