...I asked what hours were peak and off-peak on the economy 10 tariff and they said:

12am-5am Off Peak
5am-1pm Peak
1pm-4pm Off Peak
4pm-8pm Peak
8pm-10pm Off Peak
10pm-12am Peak

...And to top it all off the times are exactly the opposite of what EDF had told me on the phone!!

So I turned all my heating and water supply switches from "OFF PEAK" to "ON PEAK" in my apartment and my peak usage has halved. Strange but true!....

Are you sure about that? It's termed Economy 10 because it provides 10 hours of cheap rate electricity as per your OP (quoted).

As far as im aware, E10 just gives you 7 hours off peak overnight, ie 12.00-07.00 and then a 3 hour boost in the afternoon.

Yep I get 14hrs offpeak a day according to my spreadsheet and meter readings. I guess they have simply wired it up wrong.

Now I need to think about if its worth keeping or getting them to replace it, I already asked them to look at the meter but the customer service person said it wasn't possible to replace or even check my economy 10 meter.

I'll do the maths but it looks to me that its probably worth keeping.

That's one great thing about this site - you always learn something

Economy 10 is a special 10 hour service metered on a discontinuous basis on 3 registers, Afternoon, Night and Boost.

The Economy 10 option is available only for approved, hard wired loads and only in combination with the standard domestic plus Economy 7 option.

Consumer supplied on this tariff may encounter problems when trying to transfer (as not all companies support this tariff). Furthermore, to change to a different tariff, they may need to pay to have their meter changed.

An example of Economy 10 is shown below:
1. Afternoon
Monday to Friday – 3 hours between 1pm and 4:30pm;
Saturday and Sunday 3 hours between 1pm and 5:30pm
2. Evening
Monday to Friday – 2 hours between 5:30pm pm and 10pm;
Saturday and Sunday 2 hours between 5:30pm and 10pm
3. Night
Monday to Friday – 5 hours between midnight and 7am;
Saturday and Sunday 5 hours between midnight and 8am

Just confirmed I get 14hrs off peak a day lol

Think I've invented a new tariff "Energy 14"

Not going to tell them

No wonder my energy bills were so high having all my heating on the off peak switches, I've now removed the fuses from the switches so they should never be used again. Should save about £100 a month now.

Not sure about the E14 part.

E10 has a mixed history and is a bit of a pain across regions

The original E10 was in the eastern region and does have 3 rates with a rate exclusively for heating. Technically there were two meters in one, with two sets of 'tails' (wires coming out of the meter), one for the lights/plugs one for the heating. These meters have three rates.

At a later date Norweb also introduced a E10 metering tariff, although I could never get my head around and they were very rare. cant remember if they had a second set of 'tails', dont think they did.

after that there was a general push amongst suppliers/mops to try and standardise on these multi rate meters/comfort tariffs (by which I mean 3 or more rates). prior to this, and indeed still, all regions have wonderfully wacky multi rate meters. In EMEB a tariff called Heatwise exists, there is also the wonderfully named SuperTariff in the north east, comfort control, warmwise and a few others. There will be one for your area...

The E10 meters in regions outside of the former Eastern region and possibly norweb, have re-programmed E7 meters (it's cheaper to reprogram the firmware of a meter than design a new meter...) these only have one set of tails and therefore no seperate rate for heating.

The advantage of this is that any appliance can benefit from off-peak electricity, whereas those in the eastern region can only put their washing on at night for 5 hours, if you live outside that area you can put your washing on during your afternoon boost.

I theory all of the big 6 suppliers should have some form of E10 compatible tariff as now all regions install E10 in one shape or another, they have to support the customers in that region. getting on to this these tariffs and if you would want to is an entirely other question.

It could also mean that you are on a E10 'tariff' for one of the other multi-rate meters that exist in your area as your supplier may have tried to align/simplify their tariffs and lumped them together. with 'off-peak' covering all the different rates

The most off peak hours i'm aware of are E18 in the Eastern region although this is expressly to match a E18 'wet' boiler which heats like a gas combi one (ie when you turn the heating or hot tap on)

just about the only people that know the timings of your meter are the meter operator for your area, these are seperate from your supplier, but will most likely only talk directly to your supplier and not yourself.

Just state as is usual with my posts, I work for E.ON, although the knowledge I gained in their Tariffs/Elec Meter exchange department stopped 18months ago when I moved to a new role. Explaining E10 is a bit of a hobby of mine thou. If you do need to speak to your supplier about it the kind of specialist knowleddge of these meters will be burried away from the call centres in the metering or tariff department try and get through to them and even then it's more likely they'll know the history of your regions meters.

Thanks for the explanation, I think from all my conversations with EDF I can safely say you probably know more than them!

No idea why they installed economy 10 in my new build apartment. I wish they had gone for the normal meters now as its cost me a lot over the last 2 years.

All sorted now though with a few adjustments to the heating timing.

E10 will show about 5 reads on the meter but e7 will only have 2 and possibly a 3rd as the total reads added together. Call your supplier and give them the seriel number on the meter and on the meter may be a date of when installed, happened to me they hadn't updated a metr x change ie didn't update my meter which was showing as e7 to a standard meter theirfore billing me on e7 tarrif.

Heatwise meters have 5 readings. Day and night on one half of the meter that controls the lights/plugs and 3 reads for boost/evening reads for the heating. Heatwise meters are exclusive to the East Midlands region

An E10 will never have 5 readings.

Heatwise meters are two meters in one. There is either a single rate or E7 part to the meter and unless the other parts details are received by your supplier and setup on their system correctly then their system will see it as an ordinary meter.

This can lead to a number of incorrect signups from other suppliers as heatwise meters are only truely supported in the East Midland (E.ON) region, not that other suppliers cannot support them on their tariffs, but what usually happens is that the other supplier will only sign up the standard part of the meter via its unique MPAN (the other part has a separate MPAN) this can happen mainly through comparison sites and customers not fully understanding heatwise meters.

There is a similar potential for other multi MPAN meters to be signed up incorrectly, but they usually drop out of a sign up process earlier as the 'standard' part of the meter that they usually have isn't listed as one and is usually listed as part of a unique setup that is flagged up earlier.

This also happens with Restricted Hours Tariff meters. These are generally precursors to these multiple meters in one and usually have two distinct meters.

Point is get to know your meters and the readings...
