Help with gas and electricty company
Options
Hi following the report on watchdog about overcharging gas companies with ft3 and metric meters i have a imperial ft3 meter and it states
Imperial calculation - if your meter measures in cubic feet.
To convert the readings on an imperial meter from imperial units to kWh's the company should do the following calculation;
(The number of units you've used) X (The metric conversion factor) X (The volume correction factor) X (The calorific value of the gas) divided by 3.6 = kWh's.
The number of kilowatt hours you calculate should match the number of kilowatt hours the energy company says you've used. If they don't, then you should query your bill with your energy supplier
Now my bill

Can some one show me how they have calculated (The number of units you've used) X (The metric conversion factor) X (The volume correction factor) X (The calorific value of the gas) divided by 3.6 = kWh's.
The number of kilowatt hours you calculate should match the number of kilowatt hours the energy company says you've used. If they don't, then you should query your bill with your energy supplier
because they do not show this calculation on my bill above or have i got it wrong? Also is my gas supplier really expensive( SCOTTISH POWER ) ???? i did do a comparision online through energy helpline.com as recomended by money saving expert they recommended British Gas web saver 2 and after reading review found that customers who did switch were not happy with the prices as they did not save money and there bill was even higher has anyone got an ideas on this topic thanks

Just a quick note please edit out your meter number if you don't want to post personal info.0

Divide the kWhs by the meter units
5420 / 172 = 31.5
You are being charged for an imperial meter. If you were being charged for a metric meter, the result would be about 11.2.0 -
(The number of units you've used) = 172
(The metric conversion factor) = 2.83 (that's the number you appear to have been missing)
(The volume correction factor) = 1.022640
(The calorific value of the gas) = 39.2
divided by 3.6
= kWh's.
Hence:
172 x 2.83 x 1.022640 x 39.2 / 3.6 = 5420
Regarding the cost of gas, well you have been charged 3.817p/Kwh plus a daily standing charge, plus vat (and been given a discount of £5.54 plus vat) = £224.64
If you had bought from ebico, you would have paid 3.77p per kwh (reduced to 3.675p/kwh since 30/03/2009) including VAT with no hidden extras/discounts.
So 5240kwh would have cost £204.33 (or £199.18 from 30/03/2009)"Now to trolling as a concept. ....

THANKYOU PREMIER
Thats exactly the explanation i needed your a star premier by the way why have they decieded not to show the The metric conversion factor) = 2.83 that is missing on my bill??? why have they not printed this info on my bill? Thanks everyone else you too have helped and i think i will be changing my gas and bill supplier do you think it is better to get dual fuel??? also i did a comaprsion and it returned British Gas web saver 2 but i have heard that some customers did switch only to get a higher bill or do you think ebico the company you metioned ? or will it be the same if i switch i wont really get the price down even if at first that is what they appear to show on the comparision website?0 -

Why is mine:-
Gas calculationWe measure the amount of gas you use in hcf.
We use the following calculation to translate
these into kilowatt-hours (kWh):1 hcf of gas units used = 942 convert to cubic metres x 2.833 multiply by conversion factor x 1.022644 multiply by calorific value x 39.600005 convert this into kilowatt-hours ÷ 3.66 giving kilowatt-hours used = 2992

I assume you are questioning the calorific value (as it is in big numbers)
This is the energy content of the gas - sometimes the gas has more energy in it so you have to burn less for the same heat. This is tested at certain points on the network everyday, and an average is given for your bill.
So the value changes with time, and different parts of the country. There's something on National Grid's website with today's value
