I'm currently on standard variable with EDF.-a Over the last 12 months
the bill has totalled
-u2055.93. (inc 5% VAT)
Elec 27.89p per kWh S/C 58.32p per day
Gas 7.92p per kWh S/C 36.68p per day
EDF are suggesting changing to a fixed tariff. They are offering:
Simply Tracker Sep27v3 (Expires 1/10/27) - Estimated annual bill -u2,373.52 Elec 27.95p per kWh S/C 49.56p per day
Gas 8.61p per kWh S/C 30.63p per day
Simply Fixed 2Yr Oct28v2 (Expires 1/11/28) - Estimated annual bill -u2,422.19
Elec 27.93p per kWh S/C 56.41 per day
Gas 8.60p per kWh S/C 7.48p per day
Simply Fixed Oct27 (Expires 1/11/27) - Estimated annual bill -u2,602.26
Elec 29.71p per kWh S/C 47.81p per day
Gas 9.92p per kWh S/C 29.16p per day
(The estimated annual bills for the fixed tariffs include elec at 0% VAT
and gas at 5% VAT. EDF base my annual usage figures as follows:
Elec - 3,091 kWh Gas - 14,139 kWh)
The price cap will increase 4% tomorrow, and now they expect another 20%
in January. Adding another 25% to my current bill brings it close to the estimated bills of the fixed tariffs, so is it worth bothering? No doubt there are other suppliers with cheaper tariffs based on having a smart meter, and paying by DD, but I'm sure that EDF have those too.
Can anyone explain why the standing charge changes across tariffs?
Aren't those costs behind those charges more-or-less fixed?

Ouch. I recently looked at the prices at Outfox and the gas price started with a 6... although maybe the futures market has moved on. Did you try a comparison site?

They're just a pricing knob. All the tariffs have is a straight line
y = mx + c
where y is the bill, x is the number of units, m is the price per unit and c is the standing charge. They offer various tariffs with different m and c
to target different markets - heavy users, light users. The standing charge is just the fixed part of this formula. You can be sure they get the money either way, whether some of it is part of the unit cost or not. They know the spread of customers' consumption and so they set the tariffs so the
house wins either way.

Well, I'm pleased that you and I are in agreement. I just didn't know exactly hoe they calculated things.
I'm not so much of a "winging nihilist" (see reply to my OP) as a
"whinging cynic". I believe that /nothing/ the energy companies do is
ever for our benefit, but always works to their advantage. Heads they
win, tails you lose...
I did sign up to a fixed rate, so the war in the Middle East will soon
be over and the prices will drop. Just my good turn of the day. ;-)

In my mail in-box I'm being offered fixed price deals from the big
companies that "must end" in a couple of days. The selling point is the current rise in price and a suggestion that they rise again at the same
rate for a long time. These deals are for 2 years and with -u125 exit
fees. The cynic inside me suggests it's to lock people into a high fixed price for the next 24 months but the companies know that prices will
likely to fall within the period of the contract.
As Theo noted, the companies never lose. It's why I signed up for only a year. The exit fee is -u50. I don't expect to gain or lose anything significantly different from what I'd pay as "standard variable".
The only slight benefit is that now EDF will stop pestering me to change tariff - at least until the one I'm on is about to expire. I guess that
if I'd signed up with one of the utility cost-comparison sites, I'd get umpteen emails offering me the best rate too. I already have that with confused.com for insurance.
Just give a fake email. When switching, go to the energy company direct and see if you can find tbe same tariff. Most of the cheap tariffs don't pay a kickback to switching sites - they still show them, but you have to go
direct to order anyway.
