The smart gas meter gives readings in cubic meters, which is what one wants to thoroughly check ones gas bill. It also gives the kWh. But the OVO website, the IHD, and now the OVO bills only give the readings in kWh. [The bills used to be in cubic meters, as required.] So I go to the smart meter to get the reading in cubic meters to do my own calculation, as I have done for many years. But its values do not agree with the kWh values in the bill. Today, only 2 days after the end of month, it gives the running total for the gas as 244 cubic meters and 2735 kWh – both of which are far too high. But the OVO bill for the end of the month had a running total for the gas of just 230 kWh; and if one calculates what the corresponding reading would be in cubic meters it is 20.4 (using the latest calorific value factor, and which only varies slightly from month to month).

The OVO bill makes sense with what I would expect, so what is the gas smart meter (so called) doing?

[By the way, like most gas meters it is near the ground; but whereas I could read the old analogue meter from above, I now have to lie on my side, on the ground, outside, to read the ‘smart’ digital display!]

Hey

Just so you know I've changed the title of your post and added some tags so other users looking for similar information can get to it easily.

Let me just say this first of all - gas is a tricky one! There are a few variables that change all the time, meaning being very precise is really difficult.

First there's the volume in which your meter measures, which could be metric (meters cubed) or imperial (hundreds of cubic feet). This needs converting into KWh, as this is what we charge in. You'll notice the unit rate on your MyOVO account is listed as 'per KWh'. There's a different calculation for metric and imperial, but the one you need will be indicated on your bill.

While we're converting, we also factor in the calorific value. This means, how much energy does the gas produce when burnt, and depends on what gases are in the mix, and the quality of it. This varies from region to region, and month to month depending on who we're buying gas from and where it's shipped to in the UK. Our suppliers let us know the calorific value, which is fed into your bill. However, we do only display this to a couple of decimal points on your bill, where in actual fact it might be a few more. We do this for ease of calculation.

Your gas smart meter measures the reading in meters cubed, and this is what it displays. Though it can calculate and show what this is in KWh too, we display it as the volume rather than the KWh to be in line with traditional meters.

It might be easier to talk through the charges with a member of our team, who you can reach on 0330 303 5063. They'd be happy to look over the figures with you to make sure it all makes sense.
