Ofgem is proposing suppliers offer one price-capped tariff that includes the standing charge, and another that loads these costs on energy usage charges instead. Customers could choose which suits them best.
Time to get your spreadsheet skills honed and records kept. Deciding which will be best for you will be no easy task as shifting the SC to units (kWh) used (gas and / or electric) will be variable and could be more expensive if you are not aware of your usage.
I consider myself a low user with about 1.65 units of gas and 1.98 units of electricity per day, on average, throughout the year so I will probably be better off paying per unit with no SC, but the devil will be in the detail.
I currently pay SCs of 35ppd for gas and 65ppd for electricity; that's £365 per year in SCs alone. I might be able to reduce that, but it will all depend on how much the unit cost goes up.
