'Missing' electricity account

Extremely interesting and absolutely critical to your provider being transferred.

'ie. 39.3x1.02/3.6=11.135'
Check with BG - 39.3 is the current CV in use today...

Today - that is an average figure for today but what about yesterday,  tomorrow, in 2023 ?

Do you have a table or graph showing the variation, over say a one year period, of a suppliers CV used for billing purposes? It would be very interesting, particularly if it changes as much as you say...

Thank you Nik,  for your very helpful comments

Side issue:

In the table, the figure 1113475 or 11.135x10^5 is interesting-

11.135 is the conversion factor currently in use by British Gas

ie. 39.3x1.02/3.6=11.135

[The conversion factor is used by the supplier to convert m³ readings to kWh for billing purposes]

Please correct me if I'm wrong

Ignore the 113475 figure: it is what is known as a smart meter hexadecimal error. For that matter ignore the right hand side table as it comes from a fixed proxy CV which, for billing purposes will be ignored.

Gas bills are based on the volume of gas used converted by the supplier to kWhs. This calculation uses the average CV for the billing period truncated to one decimal place.

Suppliers are banned by Ofgem from using fixed CVs. However, smart meters need to have a fixed CV if the IHD is to show anything that is meaningful to the consumer. 

You can look at past and present CVs for your supply region on this website:

This month so far the gas supplied to my property has had CVs varying from 39.2 to 39.7

We're losing the thread!  Maybe it's time for the OP to start a new one to post questions about gas and Calorific Value variation.  The "missing" electricity account will remain just a mystery unless the OP can supply more information - and even then there may be nothing that can be done.

But that is meaningless for billing purposes as CV varies each day. The supplier adds up all the daily CVs for the billing period and divides the total by the number of days in that billing period. If the average comes out at 39.75 then under Ofgem rules that has to be truncated to 39.7 for billing purposes.

@westofsouth  I think we come different engineering backgrounds.  I look at something and say that is 300m away  - do you say 328.040 yards  ?   

 My FIL was in the latter (motor engineering)  dealing in the mm's - all was well till he worked in wood !

This is interesting, The IHD I used to supply an opening gas reading to Ebico seems to only display in kWh (See 'Firmware Conversion Factor' post). It displayed 6138kWh for gas. The fixed firmware CF for the Secure EG4 meter computes this as 551.2m³. However it transpires that this was not accepted by Ebico (or subsequently by the EOS).

Note I have been in contact with Secure Technical Services dept.
