Hi, others might have said all of this already, but I was getting very frustrated with many of the replies you were getting. So I haven't read the rest.
ignore the amount of the DD, that's not what's important! (You can negotiate that if it's more than you're using!! If it's what you're using then it is what it is)
what's important is the pKw charge.
the Energy cap, don't look at the average £ quoted, look at the rate pKw
also look at the Exit fee (many are 0 at the moment, but not all).
the price cap is due to go up in Jan & April so the standard variable rate is just going to keep going up & up.
the fixed rate you're offered now, will invariably be a bit higher than the SVR, but not as high as it's due to go in Jan then higher in April.
Does that help? Any questions?
