how do you work this out?

polomint_2

I realised i made a big boo boo when comparing suppliers. I changed to E on energy online extra saver plan 8 from v5...But when i just did another comparison it tells you to put in the amount you pay per DD to compare a month I pay £52.00 a month for both combined so you cant put in £52.00 in each box for the seperate gas and electric as thatll come out as paying £102 a month!

I havent a clue how its split between the gas and electric!

Any advice on how to compare them properly? Thanx

Don't waste your time entering DD monetary values. You will only get accurate comparisons if you enter your annual kWh usage, available from your bills or your supplier.

If you log in to Eon, you can find all the information you need because you can view previous bills. Look for meter readings a year apart (make sure they're actual readings, not estimates) for annual kwh usage. Or, if you have a lot of estimated readings, find actual readings from more than a year ago and calculate.

If you have, say, your electricity reading from 15 months ago, subtract from today's and divide by 15 to get one month and then multiply by 12 to get a year.

Be careful with the gas - you need to use multipliers to convert if you use a meter reading rather than previous bills.

Taken from an Excel spreadsheet I use, to work out my bill, with my meter readings.

Let's say 01/01/07 was 0000.000 and 01/01/08 was 890.123. Therefore you have used 890.123 units, over a period of 12 months.

((890.123*40.1)*1.02264)/3.6

So lets work that out:
890.123 * 40.1 = 35693.9323
35693.9323 * 1.02264 = 36502.042927272
36502.042927272 / 3.6 = 10139.456368686666666666666666667.
I'll round that to 10139.456

So that's 10139.456 kWH over 12 months. Or 844 kWh every 12 months. :eek:

Bear in mind these figures might be old, so get up-to-date ones first.

Ive only been with e on for three months so I cant look back over the year so its a lot harder to compare i fear. thanx for your comments so far

Just taken this from a recent online bill, with Scottish Power.

D. How to calculate your gas charge

Subtract the previous meter reading from the present meter reading (if you have an imperial meter, multiply the figure by 2.83).
Now multiply the answer by the calorific value and the correction factor and then divide by 3.6 to give the number of kilowatt hours.

The calorific value on the bill was 40.2, and the volume correction value was 1.022640.

So let's work out a reading of 890.128...

890.123 * 40.2 = 35782.9446
35782.9446 * 1.022640 = 36593.070465744
36593.070465744 / 3.6 = 10164.74179604 - or 10164.742 kWh, rounded up.

Much easier to enter your meter consumption readings (imperial or metric) here

:rolleyes:

Your best bet is to take the readings from the three months then, and just multiply by 4.

It will never be accurate until you can get a whole year's worth of readings, but it'll be a good estimate.

If I were you, I'd try to take meter readings on the first of every month - and give them to your supplier, also.

This is something I do religiously, but I always do it as close to midnight as possible - that way, there are no daytime variations in my reading. Not that it should matter much, anyway.

I just punch a time, date and the readings into my spreadsheet - it does the rest. :beer:

The spreadsheet contains almost monthly readings right back from 18/08/2004 until 29/08/2008.

But the OP hasn't got your spreadsheet!

You quoted me when you said that, so I assumed you were talking directly to me.
