I wish government would simply publish the cost per kWh so we can all calculate exactly what each of us will pay, based on our historical energy usage. I know we use 3400 (+/- 200) kWh of electricity every year, so a simple calculation will tell me what to expect. The crazy thing is that this cost per kWh should be capped but won't be as it all depends on what tariff you are on and what supplier you are with. In fact those who have secured a fixed rate for the next year or so could now be worse off!
