As far as the "thinner" red and black wires coming from the Henley blocks are concerned, this was very common practice in very old installations when only a smaller (usually lowish current) (sometimes single circuit) fuse box was being connected.

She thought that was for the shower. Not what I'd call low current but 10sq.mm would look thin compared to normal 25 or 35sq.mm meter tails.

As wild half arsed guess it may go to a mini CU with RCD and MCB for the shower. I've seen that where a shower is installed in a house with no existing RCD.

I did say "usually lowish"! By which I meant not supplying at 60A/100A CU or even a 45A Cooker. Yes 10mm will look thin compared to normal tails, but never the less not a major issue, substantially thicker than what's in the DNO's cut-out fuse! Her electrician will sort it.

Well … I’ve lost my afternoon boost …. It’s definitely not working today …

You're on E7, then! At least the weather has improved, and hopefully your heaters will stay warm into the evening.

Rosie1001 said:

So off to email EDF again !

They'll get there in the end, I'm sure.

I’m ok with the temperature , but my husband is poorly with ongoing medical condition and Feels the cold , that is why I keep the home really warm ..

That was my main concern about the meter change 

But as we discussed before, you should have had seven hours of charging last night (the amount your storage heaters are designed for) rather than five.

This plus the lower heat loss from your house now that it's longer means they might last until bedtime.

You'll find out tonight, one way or another.

******It was conveyed to you in previous communications that should we be unable to commission the meter it will operate as E7. We will attempt to resolve this remotely to see if we can then ensure you are on E10, although this cannot be guaranteed.

Your off peak timings on E7 are 00:00 - 07:00

I appreciate you providing the photos of your meter details as requested. I have submitted the details to our metering specialists who will ensure the team updates your records accordingly.

Please rest assured that I will keep you updated on the progress .*******

The reply I got ..what reason would stop the meter being commissioned????

At the end  of the day the heaters will only take charge to what’s asked of it / thermostat etc …then stop … 

I can’t see this new 7 hours working in a very cold weather … but I might switch suppliers by then if EDF don’t sort this out

The IHD, when it's working, will tell you what the current rate is. 

I don't think Rosie's got to that stage yet ...

QrizB said: 

Failing that, the meter display should tell you which register is the active one, at the moment you look at it.

You would think so, but I can't see it. This is what the manual says the display shows:
  


There won't be much recorded on either register at this stage, so she'd be none the wiser. There's a slim possibility that the tariff prices have been uploaded to the meter, in which case the Now > Price screen would be a good indicator:
  


Still wracking this old brain ...

Which manual did you look at? The manual for the ES-12B gives the details of how to get to the relevant screens which I've already posted previously, as well as the fact that the L icon goes off-screen when the ALCS is active on the 12B, also stated by @Scot_39.

@rosie1001 see my post here for how to read the various registers.
Also if there is lack of signal that could stop the meter being fully commissioned, wait for EDF to try and sort it out.

I can’t see lack of signal being an issue … I’m not in a rural location , I’m in a seaside town in Tyneside

No the manual states the open L icon is for L contactor open not closed.

That's not what I understand from the manual. The icon is unchanging (not like on some other meters), and only shows (= 'ON') when the switch is closed. It's of course lamentable that it shows an open switch to indicate a closed one ...

Relay state icons

M for main disconnect relay, L for ALCS.
Operating states:
M icon ON: Main supply has been disconnected
L icon ON: ALCS is on
M & L icons ON: Meter is currently in a ‘Non-Disablement’ period
M & L icons OFF: Supply connected, ALCS off 

Which version of manual I linked tge revision 1 for the es12b 7/2/ 20  above and that second line says

L icon ON:  LCS is OPEN.

Thst means port 5 restricted feed will be off.

And Rosie also stated  observed it switching off at just after midnight on her meter last night in an earlier post as tge kWh imp light staterted flashing rapidly - as kW of power flowed to nsh and hw no doubt.

"I was up and checked the meter at 12 midnight and watched it “L “ icon go out and the kWh flashes rapidly so I knew the storage heaters were charging"

Quite true. How high are the input knobs set on your storage heaters? Do you also have a hot water tank with an immersion heater?

Last night you used 42kWh of electricity. We know from your previous thread that you've got two large Dimplex storage heaters, an XL24 and an XLN24.

https://forums.moneysavingexpert.com/discussion/6584570/working-out-charge-for-my-storage-heaters

They have a total capacity of about 48kWh, but would only have been capable of storing 34kWh with your old five-hour overnight period.

So it seems likely that, when your cheap rate went off at 0710 this morning, the heaters had more stored heat in them than they ever have done before. I'd hope this means they last rather longer than usual tonight.

Do let us know how it goes!

Rosie1001

I will do … 

As I said before , thank you all so very much for your time , consideration and advice , it’s very much appreciated

Those two wires (red & black) look 6mm.  More concerning though is the apparent lack of earthing on that 'shower' circuit.
