    You take absolutely no notice of published times and go with your analogue timerswitch time. when you took that photo the timer thought it was around 12 pm. Find out when your cheap 7 hours is by observing when the meter switches over to the night rate. EDF are not interested in the accuracy of your timerswitch.

    As said above the nominal E7 timings for your area are meaningless if your mechanical clock is inaccurate. Mine is 20 minutes 'slow' but others report their clocks are hours fast or slow.

    Also bear in mind that with a mechanical clock during British Summer Time 'your' 7 hours will start an hour earlier than GMT

    That is not an "E7" switch. You have 2 cheap periods, 1400-1700 and 2330-0730. The photo,according to the timer, was taken at 12 lunch time. You need to check when you actually switch and see what register increases. You could be getting extra cheap electric during the day if you are being billed E7.

    Economy 7 - cheaper electricity at night

    The Economy 7 cheaper rate period typically falls 7 hours between 10pm and 8.30am, but that period can vary across the country. Most variations depend on the type of meter you have, and what time of year it is (British Summer Time etc).

    The easiest way to find out your exact Economy 7 hours is to look at your meter. Meters can vary, so on some meters it will tell you the hours next to the meter or on it.
    For other meters you will need to take a note of your supply number which you can find on your meter or a recent bill and you can check your region on the map below.

    That meter is what is termed "complex" (not single rate and not E7). How many different readings do you have on the 2 meters ? Are you definitely on an E7 tariff ? Does the meter definitely switch at those times, it looks like the trips are active but you need to check. Which / how many registers increase at the afternoon low period ? Is the clock telling the right time - it should be 1 hour out at the moment, just coming up to 2pm and about to change.

    Yes, its correct on GMT, I am on a day/night tariff with two meters. Yes it does def switch! When it kicks on to the low tariff my underfloor heating and hot water go live.

    Judging by the size of the cables coming into and out of the timeswitch, and possibly the rating plate (80A ?) and sticky label "18KW", is it possible it is just a timeswitch turning the heating on and off? Perhaps supplied through a second meter, but not necessarily?

    Could you post some more pictures showing the whole arrangement of meters and consumer units? Preferably from different angles so we can see where the cables come from and go to.

    This was taken before I had both CUs replaced.

    The small CU is the off peak doing hot water and under floor.

    That makes sense, the small white meter is feeding the smaller CU via a timeswitch, so the heating kicks in and out at certain times of day. I can't read what it says on the MCB labels, but it would be logical for all the other circuits in the house (sockets, lights, cooker etc) to be run off the other CU which isn't controlled by the timeswitch and is fed from the larger meter with the transparent case.

    I don't know for sure, but I've never seen an Economy7 set-up like this - usually all an Economy7 timeswitch does is switch the recording of consumption between one meter register and another. So all your consumption (lights, heating, power etc) at night will be charged as Economy7 night units.

    However, there were many different tariffs for storage heating etc which operated using separate meters and circuits like the ones in your pictures - so are you sure you are on Economy7? Do the day and night unit charges you are paying correspond to the published E7 tariff for your supplier?

    If you are definitely on E7 and your night units are being recorded on the white meter, and as per molerat's post you are also getting cheap rate heating between 1400-1700, then it looks like you are probably getting a very good deal , even if your non-heating consumption is all being charged at the day rate.

    Just to add - the SEEBOARD Warmwise tariff would be an example where special rates were available for heating only, for certain hours of the day, provided the heating equipment was on separate circuits from the rest of the house.

    Hi,

    Methinks you are on E10 tariff, with clock settings slightly out.

    How does Economy 10 work?

    Economy 10 gives you the same energy as any other tariff, but during 10 off-peak hours of the day, your energy will cost less.

    The Economy 10 discounted rates are typically broken down into seven hours at night, and three hours during the day.

    While Economy 10 offers unit rates of up to half the price of peak rates, the standing charges are often higher.

    Edit: Found this from EDF:

    Warmwise

    – Provides eight hours of cheaper electricity specifically for room and water heating at various times of the day. The room and water heating should be on a separate circuit.

    We charge for electricity for all purposes (other than room and water heating) at the
    relevant day or off-peak rate.

    Link.

    Thanks for that, that's cleared up a few questions I had, looks like the meter is more or less ok.

    m0bov, you should still check your bills/contract to ensure you are on the right tariff, and also that the readings on the bills correspond with the meters on the wall - i.e. that the cheaper rate electric is being charged for the heating.

    From what I understand, the Economy 10 tariff didn't come into being until the 2000's, one source says 2004. The timeswitch you have is much older, perhaps 1960's, and certainly was in use in 1990. So it is quite possible your arrangement of meters and CU's predates the introduction of Economy 10 and therefore the tariff you are actually on could be one of many, not all of which are good value for money.

    What you need to find out and assure yourself is whether you are still being charged on some kind of legacy tariff, or Economy 10, or Economy 7.

    Hi, I moved from EDF which was a "deemed" off peak and peak. I have now moved to an E7 tariff with another supplier as I was told it was E7. I tried to get them to change/check the meter as it appeared faulty but not got anywhere. At the moment I am on E7 tariff with the correct meter serial numbers. I have not had any confirmed meter readings yet nor a bill. So for the moment I will leave it be.

    I'd have thought that E7 would only have one meter with a day and night rate. You've got two meters, how are they being billed/recorded.

    E7 implies that all your leccy during the night would be at off-peak rates and full price during peak times. As you've got two meters it looks like one is configured to supply the heating and hot water via a timed supply and the rest via a non timed supply (unless the main meter is a dual rate)

    Check your bills to see what tariff you are actually on

    It sounds like m0bov already has and it is E7, even if the metering arrangements are not conventional E7 style dual-meter.

    m0bov, I suspect you may already know, but the down-side is you won't be getting the benefits of E7 rates for non-heating consumption overnight, but you will gain from having E7 low rate for heating in the afternoon. If electric heating in the house is the only option then the financial benefit of low-cost afternoon heating is likely to be greater than the benefit of having cheaper night-time electric for things like the washing machine, dishwasher, lights, TV etc. Even if you don't use the underfloor heating in the Summer you may well still be ahead financially just from having your hot water heated in the afternoon.

    Apart from keeping an eye on the meter readings and unit rates it may well be a case of letting things carry on as they are.

    I checked the meter details with my new supplier, Iresa and its showing peak for both. Of course there is little chance I can get to speak to anyone at Iresa seeing as they seem to be going belly up. So, I spoke with EDF who now tell me I am on complex metering! So I am phoning around to get quotes. Eon's IT system is down, nPower dont take new complex metering customers.

    Trying to think about how else I can get metered, the underfloor does'nt work on a timer, it uses the supply timer to switch on and off. The water heater is now on a timer I fitted.
