Electric - first 225 units @ 18.71p then 12.36p for the rest.
Gas - first 1143 units @ 4.370p then 3.300p for the rest

I am on General Domestic NSC - moneysavers(scot)

for 05 dec 2008 to 04 mar 2009, i have just got bills for:

£205.75 fo electricity - 1571 units
£179.64 for gas - 160 units (5145 kWh)

Am I missing something here.
How does 160 gas units (5145 KWH) at above price per unit come to £179.64p.

I was thinking about moving to Scottish Hydro, maybe not.
