StandingCharge	A charge to be levied in Currency Units per unit time when operating in credit mode and prepayment mode Note that the scale used for Electricity Meters is defined by StandingChargeScale value, Gas meters have a scale value of -5 Values can be in the range of; (-32,768 to 32,767)	sr:PriceType (restriction of xs:short)	Yes	None	Value when multiplied by the scale is GBP/ EUROs This amount is collected daily
StandingChargeScale	A multiplier applied to the StandingCharge value. Note this is the value of n in 10^n (10 to the power n).
