Problems with off-peak hours definition

    Hi All, I moved to Eon at the start of 2024 and I took a screenshot of my start-up terms showing off-peak hours running from midnight to 0700. In Mar 2024, Eon told me my hours would be changing but not when or what to.

    I believed them when they stated 0030 to 0730. Unfortunately, most of the year was taken up with a dispute as they billed me for all use as peak between April and September and they also charged me for over 2000kWh more than my meter readings showed so with all that , it was hard to tell whther my off peak hours being charged were those that they communicated.

    However, this year, I have had at least 6 alternating notifications from Eon switching between 0000 to 0700 and 0030 to 0730, also asserting that they were always 0030 to 0730 and never 0000 to 0700, even though that included a few weeks when the supposed wrong tariff hours of 0000 to 0700 showed on the Eon app, so now I simply don't know what to believe the real hours are.

    I have an EV and house battery to charge and kiln to run so I often need my full 7 hours but have no confidence that I am being charged correctly. At 12kW consumption for 30 mins at the wrong tariff, I could pay around £1.25 per day more than necessary so it is no fun being in the dark about the actual times.

    On one occasion a couple of weeks ago, when I was up late, the smart meter in-home display (IHD, which the Eon engineer who set it up in April told me gets its tariff data from the meter), actually switched to offpeak at 0138, instead of the 0030.

    I had been told that once I had my new meter (in Apr) that I wouldn't need to worry about GMT/BST off-peak hours changes, so I was still assuming offpeak started at 0030 and therefore paying a lot more than I should because I was not being given the right information.

    I do not know what to believe and Eon state that as I am on the EV tariff, the IHD is wrong, but why would the meter hold not only it's own correct tariff times but a wrong set of times that it sends to the IHD?

    Does anyone have any similar experiences or recommendations so that I can finally settle down to reliable offpeak hours for me to make full use of?

    Thanks,

    I'm on the Next Drive tariff, and the billing is done based on ½ hourly readings from midnight to 7 am current local time (i.e BST in the summer or GMT in the winter)

    However the times on the meter doesn't reflect this at all so only use them as a rough guide (this may affect users on a two-rate E7 tariff differently, where the timing triggers heaters etc to turn on)

    My meter & IHD actually changes from standard tariff to cheap tariff at 00:30 GMT (ie at the moment in BST it actually changes at 01:30 local time)

    Have a look at this thread where I confirm what the meter shows re tariff time change (half way down the page at post 8 has screenshots)
    https://community.eonnext.com/thread...ull=1#post5998

    And EOn confirmed this is the reason why they do this here

    Confused dot com or what! 🤓

    Does your drive tariff end in 2R?
    If not, simples, they should use 30 minute data and always 00:00-07:00 regardless of time of year.
    For those with 5 terminal smart meters with a time controlled circuit, there is the 2R tariff with a 00:30-07:30 timing. This is probably GMT, so becomes 01:30-08:30 BST.
    The different timings are apparently because they couldn’t get meters to reliably switch at 00:00.
    There is then the added complication of a random delay configured in each meter, so a million circuits don’t all get switched on at the same second, so 01:37 isn’t surprising.
    If you don’t have a time controlled circuit (typically for immersion and storage heaters), get on the non-2R tariff for simplicity.

    @BCM454 check the time held in your smart meter. I had huge problems (previous supplier) with an EDMI meter which was out by over 4 hours! That really got my billing wrong. My current meter is L & G which seems to sync every day.

    Not easy to navigate the smart meter menus, but hit the right buttons in the right order and you’ll find the time screen,

    Next Drive Fixed V2. Love Smart Meters but don’t trust them enough to stop me downloading DCC 30 minute data via Glowmarkt and comparing with EON billing. EON spot on so far 😄
