Hi, I've been waiting nearly 3 weeks for a reply from Eon regarding my off peak electricity. This evening I got an email and it informed me to adjust the timer on my heating system!!! I don't have a timer, just an old Hercules water tank which has 2 switches on the wall, one for a boost of water and the other is for off peak usage. This was working fine until the clocks went back at the end of October and now it comes on earlier, I wanted to know if this would still be in the cheaper tariff timescale but not sure they have answered my query. Would anyone know if I would still be getting the off peak rate or do I need to do "something" to the meter which is downstairs in the basement area of where I live. Any help would be really appreciated as I am worried now that my water is being heated whilst still in the more expensive rate period. Thank you.

@JoeSoap, thank you, however, looking at the tables you have posted for me, it looks as though I fall into the 0030 to 0730 period, however, if my hot water tank starts prior to 0030, would I be right in assuming that it is using the more expensive rate? If that's correct is there anything I can do to change the time on my meter in the basement? It all worked fine before the clocks changed. Thank you so much for your help.

I’m afraid I know little or nothing about the subject. The post I linked to was courtesy of @meldrewreborn who may be able to help a bit more when he sees I have tagged him to this thread.

@JoeSoap, thank you. That's kind of you.

You’re very welcome. Sorry I couldn’t help you more myself.

@JoeSoap please don't apologise, at least I haven't waited 3 weeks for a reply. You were really quick and you gave me something to look at which made a bit of sense but I just don't know what "timer" the Eon colleague is talking about, there is no timer! Thanks again.

I guess the customer service advisor assumed your water heater/boiler was on a timer and you could just adjust it so as to fit in with your off-peak times. Questions centred around E7/E10 timings come up regularly but seem hard to answer. Hopefully you will get some help with your query soon.

@JoeSoap yes I've been reading other people's questions which, as you say, centre around the same. It's crazy, why can't E7 or E10 be the same hours for everyone. On those 3 tables that you originally posted for me I can't see my Area ID which seems a little strange I guess. Why is everything so incredibly confusing these days? Thanks again.

@MMA Off peak times are staggered by the DNO's so that within a given distribution network area, there isn't a sudden increase in demand as everyone's storage heaters and immersions come on at the same time, and a sudden surge in line voltage as they all switch off at the same time.


Depending on the type of E7 meter you have, and whether it is smart or not, your meter may or may not make allowances for BST/GMT. The three digit time switch pattern will tell you that.

The E7 immersion heater, the lower of the two in your tank, will be switched on for the 7 hours when you are on off-peak rate. Regardless of when that time is. The meter itself does the switching for your off peak circuits.

The 'boost' which is the upper immersion heater in theory will work at any time, but will cost more if you use it in the day.

Best to never switch the boost one on, unless you really need extra hot water in the day.
