I will definitely agree with you 😃.

Excellent value 😁

I think I'm only concerned about one appliance right now which I can easily switch off overnight to see how it affects baseline consumption. I won't discount getting a monitoring device of some description although I've no intention of doing any remote controlling.

It'll level out about 1500-1600 per annum eventually.

I'll guess at an EAC of 2500 currently but I'd like to know what it actually says on your latest bill.

Mine has been going down a bit over the last 12 months too (on both utilities). Rolling averages on a downward path but starting to level out now at maybe 2350 kWh Elec/6000 kWh Gas.




As you can see the EAC follows reasonably closely - sometimes above and sometimes below - my annualised electricity consumption over the last 13 months. Gas EAC however is now consistently above by about 500kWh (but trends) the last 12 months that I have used for AA (annualised advance calculated by adding the usage for the previous 12 months. EAC figures are obtained from statements.

@Mailman

Given the weighting towards more recent usage the EAC purports to use, it seems strange that given the downward trend of your actual rolling annual consumption, the EAC is currently higher for both fuels.

@JoeSoap @Mailman @WizzyWigg

My EAC was 2257 in April, then Jun & Jul. 2000, Aug 1972 and Sep 1988.

It seems there is some correlation to my rolling year consumption figure, but with some other tweaks thrown in - like why is Sep up on august?

Yes indeed and there are some very strange swings in EAC_gas as well. For example 1st December 2022 bill stated an EAC of 8045 kWh yet 1 month later it had gone down to 5220kWh!

I think my numbers show that you need to take the EAC figures with a huge pinch of salt bearing some resemblance to reality but not good enough to over-ride customers own AA numbers. This is particularly true if the EAC is being used as the sole arbiter of fixed DD payment schedules. In the absence of AA figures it is better than nothing.

I wonder if there is a seasonal parameter thrown in to the way EAC is calculated even if electricity is not used as the means of heating. Who knows? At least I don't have to argue the toss being on VDD as EAC is just a metric that really doesn't affect me.

@Mailman

Likewise. But I always like to beat the estimate, and usually do!

[meldrewreborn]

I seem to recall that the EAC isn’ a supplier calculation but comes via an industry wide algorithm. If so it’s not something that the suppliers can manipulate to their advantage.
