Only had one meter.. the horseman one .

 it give day rate , night rate , then a third reading that never changed , then a heat reading so 4 readings altogether 


I can’t figure out the bills either … I’ve been right thru last years … they do a lot of reverse charges and amend on them 

My friend up in Aberdeen was on a very pricey THTC complex meter with SSE ( Ovo ) and managed to find the only supplier who would accept the RTS controlled meter he had when he switched to EDF  . 
Hes now on an EDF tariff called Variable Tariff Heating . Latest bills are charged at high rate -24.564 kwh , low rate - 14.785   Daily Charge is 55.898 p a day .Hes quite happy at those rates 
He got more or less the same letter as you in that he was rolling onto new rates of 25p day 25 p night .They ammended it not too long ago onto the new rates with an acceptable night rate .He has two meters also

Ok the estimated reading in Aug / Nov makes it impossible to resolve what was really going on say summer (May to Aug) but if look at May 25th 2024 -> Jan 2025

But they also appear out of sequence - so not really sure what EDF were up to - ah twigged - twin meters of course.

                  25 May->25 Aug  25 Aug->25 Nov     25 Nov->1 Jan

Day           55433C->55758   14.5->17.9              56189E->56971C                                               

                  325.2@30.16       3.37@30.16           781.9@30.16p

Night         11151C->11206E  93106E->95003E  11289E->11407C

                  55@10.54            1896.7@10.54       117.4@10.54p

                   

You will note not only are the intermediate figures for Aug on Nov on that bill out of sequence - they are also not matching on successive bills, so hunted around your old posts for a bit as had seen past photos and bills and so found this, but couldn't quickly see a whole system photo of your old metering.  (Did you post one - not just of the RTS and its cabling in an early post)

I guess the fact one uses Night and the other Off Peak was also a pretty good clue if had spotted it.

However If I go back to the post here - that covers a bill covering the full period

Day                      12C                                                     12C                          

Off Peak               91972C       93106E      950003E       95517C

And the Aug to Nov numbers above are those intermediate numbers on the second meter - so you posted them in the midst of the other meter ?

Curiously the day reading is in line with the RTS meter rate 1 posted on 31st Jan here at 57335, https://forums.moneysavingexpert.com/discussion/comment/81239456/#Comment_81239456

Did both night readings come from the Horstman ?

Taking the customers readings over May - Jan 1st = c221 days 31 wks / 7 months and from both new posts above and the old 31st Jan post

 Day = 56971C - 55433C = 1538 kWh @ 30.16   - or approx 220 per month

 Night1 = 11407C - 11151C = 256 kWh @10.54     - or approx 36 kWh pm  

 Night2 = 95517C - 91972C = 3545 kWh @ 10.54  - or approx 500 kWh pm - weighted heavily to winter months.

 Total                                    = 3801 kWh

So Night1= 36 kWhpm  - c1 kWh per night on night - doesnt appear to be much more than background / lights / FF etc - so assume all the heavy loading either on old day - for things like hot water or on night2. (perhaps even immersion het tank on night 2 - but an electric shower on day1 / night 1 depending on timing)

But sadly without readings for Aug and Nov cannot use to differentiate summer vs winter with heating likely use.

Until those NSH kick in and make snug £+ a day cheaper potentially (7hr max x 2x 3.4 kW x 3.4p/kWh = £1.60 - c£200 over 4 months on high) = its likely nearly as cheap on E7 as it was on E10 Mar - Jul. Even the fix premium is of the same order as the c1.2p multirate price drop I saw in July.

As my other post above - take a few weeks off once you are happy with any Octopus meter update / operation - to your new E7 rates and times - and then use the readings from that to guide a future decision.  

Only had the one horseman meter for my home , two mpans
