Unscientific, I know, but I've just had this quarters electric bill and it is less than normal. Looking back at past bills, my electric consumption costs have been more or less the same, give or take £5. This quarters bill I am nearly £20 better off, and the only difference I can see on my usage is that I now do not have a S1 and free-serve digibox, but do have the BT Vision+ box. This change was done 5 weeks ago. Could the removal of the S1 and digi box and swapping in the BT Vision box make that much difference? If so, then retiring the S1 and digi box is going to save me in excess of £45 a quarter.
