cost of one unit of gas/lec

this_year_2

:hello:what is the average cost of one unit of gas and electricity...as i am trying to see how much i spend on fuel a week, up to now i have used 2 units of gas and 37 units if electric...

any idea's

Depends, a gas 'unit' could be approx 11.5kW if you have a Metric meter(measures cubic metres) or approx 32kWh if you have the older Imperial meter(measures in 100 cubic feet)

The average price of a kWh of gas is probably around 2.4pence.

An electrical 'unit' is equal to a kWh and if you have a normal tariff(not Economy 7) will cost anything from 6p to 11p depending on your company/tariff and where in the country you live(there are large regional differences)

If you have already had a bill(or know your tariff & region) you can always look it up!!!

Electric is easy since 1 unit on the meter gets charged at x pence each
But then they give you the 1st x at one price and the rest at a lower price, no doubt the switch over point varies by provider in my case ,
1st unist are charged at 19p and rest @ 9p

Gas is differnet since, they charge you by kWh, and there needs to be a conversion ( calorific value currently 39.38) between clicks on the meter which are Cubic Feet, into kWh
Bill in front of me says I used 360 units which works out out 11,493 kWh
and Gas kWhs are charged at 4.22 and 2.39 p per kWh


But now I've checked my bill I'm not sure about kWh conversion

This bill lists
units used = 363
kWh = 11493
Calorific value = 39.3837
Correction factor (??) 1.02264

How to get 11493 from 363 ?
but 363 * 39.3867

tripled

There is a fairly good (although slightly rambling) explanation of the whole thing here:

http://www.ukenergy.co.uk/pages/gas-kwh.html

Your meter measures in cubic feet.

First convert hundreds of cubic feet to cubic meters
363 * 2.83 = 1029.29 m3

Then multiply by correction factor
1029.29 * 1.02264 = 1050.56

Then multiply by calorific value
1050.56 * 39.3837 = 41374.46

Then divide by 3.6 to get kwh
41374.46 / 3.6 = 11492.9

This figure has been rounded to 11493 on your bill.

So 2 units used this week is:
2 * 2.83 * 1.02264 * 39.3837 / 3.6 = 63.3 kwh

This would cost you 63.3 * 4.398p = £2.78 (before any dd discount)

"Conversion factor" sounds like the gas industry equivalent of "multiplying by the number you first thought of"

Smoke, mirrors and now gas
