Seems pretty high although it's not impossible to be that much.
Do you have gas? No
Do you have underfloor heating? No
Do you have air conditioning? No
Do you have an insane amount of fancy spotlights all over the place? No
If the first answer is no and the other 3 are yes (which would be normal in a swanky apartment) then it seems pretty reasonable.
No gas just electric, no to everything else, apartment isn't swanky at all, just fulfills my needs for the week while working. I hardly use the place to be fair, I'm usually out for 12 hours + a day and not there on weekends, that's why I'm pretty surprised at the amount.
Not growing Marijuana either before you ask lol..
