When we conduct a comparison we will look at the amount you are paying on your current tariff (until the end of your tariff) and then the standard tariff with your supplier (for the remainder of the year) and compare this to an annual cost with your new tariff. So if you have 10 days left of your tariff we’ll work out your current costing at 10 days of your current tariff and 355 days on a standard tariff and compare this to any new tariffs referencing your annual usage figures.
