Oldnproud you are on a variable rate so it will go up or down but the cap means it won’t go higher than whatever the cap is. Your old bill I assume was on your previous fixed rate.
Oops, my August bill overlapped both the period when I was still on the fixed rate, and a couple of months on the standard variable. The figures that I gave above were from the standard variable period, not the cheaper fixed tariff period.
Maybe I'm overlooking something, but I don't see why my unit prices / standing charge should have gone either up or down since then.
The fixed tariff rates showing on the August bill were set at the current price cap.
That cap has not changed since then, but the unit prices and standing charge showing on my account today are very different from those showing on that bill, and certainly not in line with the current cap - as far as I can work out, they are above it by a huge margin!
I will be checking with British Gas in the next few days, but in the meantime, I'm assuming that they have prematurely updated the tariff details to the new October ones.
