You are out by a factor of 10 there, 100 kWh = 300p


OP, go to any of the comparison sites and input your post code and tariff name. It will then show you your unit costs and daily charge

Some of it is out by 10, some is out by 100.

Hello Guys -

Well today i finally got the answer i was looking for!! I rang SSE
They confirmed with the tariff im on that i pay the following.....
1 unit = £0.375p
10 units = £3.86
100 units = £38.56

I took a reading on Sunday morning and again this evening - we have used 7.11 units of gas.
Therefore 7.11 units multiplied by 0.375 = £2.66 of cost

Gas sure as hell isn't cheap !!! - we only had it on for a few hours in the morning and a few hours later in the evening.
Thankfully were at work monday to friday through the week so im going to now monitor our week day use vs our weekend use next.

Now that i have these basic formulas im planning on looking at how to use the gas system more efficiently.

You'd find it a lot easier to work in kWh's, which, being a unit of energy, is what you are billed in. Meters measure only volume (in your case, cu m), since the energy value varies.
Gas is still by far the cheapest fuel per kWh-about a third of the cost of electricity, and £960 pa is well below the average amount. You won't of course be using £80 of gas per month at this time of year, since about 75% of your consumption will come during the coldest quarter.
Your calculations appear to ignore standing charges, which become a significant percentage of the total bill if you are a low user.

As above, use kWh for your calculations. The CV can be downloaded from the NG website and you can work out your costs almost to the penny over a long billing period. My unit (kWh) cost is 2.8836p which means a meter unit (cu m) could cost anywhere between 28p to 34p, 29p to 36p including VAT at 5%.
