I want to use a comparison site to, well, compare energy suppliers.
I know my total meter readings for the year, but I want to convert to kWh.
I know my gas meter is metric and assume all electric meters are the same.
Web advice seems to vary so I need advice.
I know I can use house info, but I have a large old house and only use part
of it. I also know what I pay monthly, but somparison sites want gas &
electric seperately.

Multiplying m^3 by 11.2 will give you fag packet kWh

The 11.2 is arrived at by multiplying the atmospheric correction factor,
and the calorific value, if you want better accuracy use the values
which should be on your gas statement.

And make sure that your meter is reading m^3 rather than ft^3. In the latter
case, the conversion factor is about 31.

It's weird that the conversion factor from m^3 to ft^3 is only 2.8, because
you'd expect it to be roughly 9 (very roughly 3 feet in a metre, then cube
that).

or 27

Also, most imperial meters read in hundreds of ft^3

1m = 3.28 feet, 100 / (3.28 ^3) = 2.83

Presume they bill using a monthly/quarterly average?

Duh. 3^3 is 27, not 9. Whoops!

The last 3 energy companies I have used have the yearly kWh estimates
seperate for gas/electric, this info is available from your Bill.
The estimates are reasonably accurate and unlikely to alter the kWh
pricing.

Your meter has a regulator on the top - the pressure delivered to your
gas pipework is determined by the regulator (not the pressure in the
pipe on the street, which might go up/down according to demand, changes
in temperature (Boyles law).

The one thing that does vary is the calorific value of the gas (energy
per cubic metre). This varies by area and time of year and is shown on
your gas bill. Mine varies between 38.8 and 39.4 MJ/m3.
The reason for this is that although natural gas is nominally methane,
the stuff that arrives in your home contains other compounds, e.g.
ethane, CO2, which depends on where the gas originates.
e.g. gas coming from Morecambe Bay (Lancs) will be different from that
arriving at Bacton (Norfolk).

There are approx. 35.3 cu.ft in a cu meter.

Cubing 3 gives 27.
Arithmetic is not your strong point then?

I've been with OVO for about 6 years. They were no help telling me what I
have used in kWH and their online website and/or chatline are singularly
unhelpful. They wanted to up my bill by ~30%
I've jumped ship as I have no leaving fee to pay AND they owe me about £200

I was with Ovo a couple of years back and then they had an estimate on
the bill for kWh usage, at that time I found them ok but switched for
cheaper fuel costs.

When you leave a utility company they will generally continue to take
your dd until the final bill is finalised this can take up to 6 weeks as
the readings have to be verified by a 3rd party as dictated by Ofgem.
I know it is a pain but you wont pay for the same fuel twice, it does
balance out.

Upping the dd payment is normally irrelevent as it is linked to your
usage (based on average consumption) it is the overall package that
counts ie cost per kWh and daily charge.
