Could any one help with this query please.ive spoke to E7E to find out my economy 7 off-peak times and they told me between 23.00pm-07.00am,does this mean there's an 8 hour period or does it mean it's 7 hours in this period?

The switching times are not supplier related

E7 (or Economy 7) allows for, as the name suggests, 7 hours of cheap rate electricity every day - not 8 hours, otherwise it would be known as E8

Your supplier will not know (or care) what the actual switching times are - they are set locally and your supplier supplies nationally.
Moreover, the times may differ from meter to meter, depending on how the meter switching time is actually set (some of the more up to date meters use teleswitching for improved accurarcy)

Most areas switch (or at least aim to) for 7 continuous hours during the period 23:00 and 07:00 ... but this can also change depending on the time of year (i.e. when the clocks change)
Also, I believe at least one supply area does not routinely give the 7 hours cheap rate in one continuous block

Perhaps the best way to identify your own switching times is to refer to your own meter?

Thanks for the information .ill check out my meter

I've just been setting up a spread sheet to calculate my first quarter with E7E and when putting in the tariff changes I noticed that on the recent notification the rate up to Dec 31st is less than I had been quoted as the November price rise. Has anyone else had this?

I found that the prices given in the new email did not include 5% VAT (even though it says it does).

Thanks, that'll be it.

I checked my E7E utility bill against my spreadsheet figures and found a small discrepancy in the gas energy used, although it became quickly obvious where the problem lay.

To convert Hundreds of cubic feet into cubic meters you multiply by 2.83

E7E seem to have re-invented volume measurement as they have used a factor of 2.83282 in one bill and 2.83200 in another.

They say that they use 2.83 but when you divide their cubic metre figure by the hundreds of cubic feet figures (that they have calculated), I ended up with a slightly higher conversion factor.

In one of my bills, the meter units are 75 hcf
E7E’s converted it to 212.4m3

It should be 212.25m3

Not much, but as Tesco say “every little helps” THEM

Hate to say this, but in your example they're pretty much correct !

1 inch is exactly 2.54mm. That gives a conversion ratio of 2.8316846592, which makes your consumption 212.37634944 cubic metres. Or 212.4 to four significant figures...

What you say is mathematically correct to National Physical Laboratory definitions, but here we are talking commercial standards.

The accepted standard value for utility calculations is 2.83, as defined by HM Government Office for product safety and standards.
Every other utility provider (including E7E) that I have used accepts this value and they quote this figure in their explanatory notes on bill calculation. All providers publish this figure of 2.83 on their websites (and bills of course)
What brought it to my attention is that this is the first time I have seen a discrepancy between a bill reading and my spreadsheet figures, so I investigated further and thought ‘’the crafty devils’.
Like one of your earlier posts, still not sure whether it is cunning or incompetence

I am going with cunning! There are many little things that they keep hiding that keep adding to their benfit and have no way of being discovered by the average person. I am still annoyed that they are saying my tarrif is "a" on my bill but charging me prices from tarrif "b".



May I ask how much this calcualation error is costing? Is it pennies or pounds? I am just curious, like you say all providers should be using the 2.83 value.

It is only pence, but really it is a matter of ethics; in my case it is £0.53/Annum
Multiply that by the number of customers with imperial calibrated meters however,and you end up with a few grand of free cash.

I also have the same a and b tariffs, but I shall be rid of them in a few days time (hopefully)
