Exactly. so why did they increase my DD to £180 if £144 is enough to easily cover my annual bill. i would have been £460 in credit and currently keeping usage below my current annual usage. So far this year i have used 1800KWh electric and 2800KWh gas. Expecting gas to jump up due to colder times coming and heating coming on. Maybe 4000KWh of gas tops. Should be coming in under annual consumptionWorks out at around £1,700/annum at Energy Price Guarantee prices.
