    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.

    What area are you in? These are UK wide timings

    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.
