Ta, inc or ex VAT I think inc but the numbers I have are for E7 in Norweb (Electricity NW, these days) area, leccky only.
I think you might find that the £70 DD discount is a reduction in the standing charge and is already included in those standing charge rates. Rather than the combined bills actually being reduced by £70.
16.442p/day is only £59.94/year.*IF* you have duel fuel, otherwise it's worse (I think) but the unit rates mean a £280/year saving for me so a fiver is niether here nor there.
Thanks for the heads up, presumably v10 runs to the 1st Nov 2015?
