you cant say its harsh without getting further information! do you have a debt on the account from a previous quarter or year that you are still clearing off? have you been recieving estimated or accurate bills every quarter? if its accurate how much does it state your usage is for that period of time? got to look at your yearly usage as well for both fuels to see if your d/d is set at the right amount and finally how many payments have you made on your current scheme? you could be due a reassment which means you could be about to pay less or it may have just been done and thats the right amount!

also people and houseside only have so much effect ive seen some massive houses with tiny bills and tiny houses with massive bills, its completley down to the way property is set up, also in regards to price the likely saving between the energy companies is really only 20-30quid!
