Hey guys thanks for your wonderful responses. Basically we've been paying the gas bill every quarter. We switched over from N power, so it's been the meter reading from the start that I gave them. So no debt being carried forward (although landlord said that the last tenant never paid their bill and they lived here for 2 yrs).
The washing machine used to be on all the time, everyday for several hours. Until like a month ago (it's broken, people don't use it much anymore). so that's what I thought could have been the problem. If it is rigged, can I sue the landlord? Since it's not honest and no where in my contract does it state that I'm responsible for paying for everyone's use of the machine?
BUAS, this house is 1000000 years old and there are cracks everywhere so I guess we're not energy efficient but I still think 1000 bucks is too much.
By the way, we've lived here for about 11 months. In the summer time when I didn't turn the heater on at all we paid like 200+ for 2 or 3 months (at this point we switched so I think it was a 2 month bill).
Thanks for responding everyone I really really appreciate all your input
