Can anyone work this out...

[BeyondsEnergyObsession]

Ive been with eon (duel fuel) the entire time I've lived in this house, so at least ten years. It swapped to eon-next this spring, which is officially (apparently) a new supplier. Hence they can't tell me what I have used for the last year, they can only link me to old bills.

Now the thing I'm confused with...
As I said they can't directly tell me my usage, but they can give me an estimate. My electricity estimate is near enough spot on with what my usage is according to my meter. No problem. Now gas, is not so simple.

My gas estimate is in the region of 26,000 kw/pa
My estimated meter reading last august was 3505 (only an estimate I know, but this fits perfectly with actual readings in other months), and this august is 4604 = 1099kw/pa. Last month I used 355kw of gas (back boiler GCH/hot water, using hot water only). I don't run my heating anywhere near 24/7 in winter either.

So, does anyone know how this 1099 relates to my usage (should there maybe be a 0 on the end and I used 10,990kw last year? That sounds vaguely plausible...?), and where the hell the estimate of 26,000 kw/pa has come from?

Obviously if no one can figure it out, I will have to attempt to explain this to eon!

If it helps, I was apparently overpaying my gas, as I had a £400 refund on the gas side of my account back in June. But this is now months down the line and if they had over-estimated my gas, surely they should have fixed my estimate?

Thank you for any input 🙂

Last month I used 131kWh. My annual usage is around 11000kWh/per year. Live alone, didn't skimp on showers or heating past 3 years (roughly same usage each year)

don't you have any old bills?

The gas meter isn't in kwh its in m³ or ft³
There is a calculation you need to do to convert the reading into kwh
1099m³ x 40 x 1.02264 ÷3.6 = 12487.57 kwh

I used 40 as the calorific value in my calculation but other companies may use slightly different values. This explains what the values are for:

What is the calorific value?
The calorific value is the amount of energy which gets released when gas is burned. It’s measured regularly by the National Grid and it’s the same for all suppliers. A typical example is 39.2, but you can see the current value by cycling through the display screens on your meter.

What is the correction factor?
The correction factor converts gas units into kWh by working out the volume of gas based on temperature and pressure. It can vary slightly, but all suppliers use a standard factor of 1.02264. This makes sure we all get the same number of kWh for each cubic metre of gas.

Perfect! Immensely helpful post 👍

I'll have a look on my meter asap

39.3 calorific clue so annual usage = 12,269 kWh 🙂

Thank you so much!

Value, not clue

This caught me out when I was young and stupid. I nearly shite myself when my first bill was 10 times what I budgeted for. 🤪
