Hey there, Eon do have reviews in the spring time, not only is this due to financial year, but also because you can build credit in the summer and use that up in the winter to get 0 in the spring. Phone them and ask when your review is due.

They do review the direct debit on every bill, so if your usage goes up massively one quarter, they will increase your direct debit to prevent you getting into debt. Make sure you get readings every quarter, because in the past I had increases on direct debit based on estimates.

Autumn reviews no longer exist. Everyone is reviewed in spring.

Phone them and ask for their reason that prices went up. They explained it to me, and I'm happy with it. Something to do with buying in bulk, so their gas was bought at a high price. BG did decrease prices recently, but only puts them in line with the other 5 big suppliers (they are more expensive to start with). I think there should be decreases in the line in the next month or so. Unlucky for those who have fixed prices (should have really capped), especially those with BG up to 2012!

They should have sent you a letter about the increase to the direct debit. Phone them and ask.

Same for us with Scottish Power - our DD has just gone up again from £26 to £35 to £47 per month - why, I thought that energy costs had peaked for the time being ?

We are on annual review with e.on for electricity, the review date is September and as expected the review was done and the direct debit went up from £47 to £57.

Surprisingly, we had the bill for quarter from November and quess what we were reviewed again and gone up from £57 to £66, we rang E.on and was told that E.on were altering the annual reviews to be in spring, being financial year end, would be the predictable reason, sounds nice for p.r.

NOW, couple of things came to mind:-

1) since when was November in spring?

2) does E.on think annual means 6 monthly, quarterly, or just when they feel like it?

3) for those that have review in autumn, having gone through summer with hanging washing out, salads and bar-b-que, long light warm nights with little need for turning lights on and little use of central heating, moving review to spring, after winter with having to used tumble dryers, greater use of cookers for warm food, and cold dark nights with lights and heating on, doesn't this mean that the reviews will come out higher for longer through the year?

4) the power companies said when the cost of crude oil went up that energy production was linked to that and so put up prices straight away, now it's down to $60-$64 from $147 per barrel, even with the drop in dollar exchange rate, the price hasn't dropped that quickly, from our experience, actually gone up?

5) this change has occured without E.on advising customers of the alteration, surely this is illegal?

In short, be careful what you sign up for, they may just make you pay for it.
