Are E7 and E10 different meters? Is E10 right for me?

[adminKeymaster]

Hi Imran,

This site is E10 specific… but only because E7 is already well catered for – you can get price comparisons on various websites, just google them.

You put your supply in as ‘2-rate electricity’ or ‘storage heaters’ or ‘white meter heating’ and you should get a 2-rate quote for Economy 7.

Cheers,
Mark

Hi Tony

You can find a list of energy providers who support the warm home discount at this link https://www.gov.uk/the-warm-home-discount-scheme/eligibility

Weather e10 is suitable for you depends on when you use your heating and hot water boiler. E7 will give you 7 hours continuous heating overnight where as e10 gives you 3 periods throughout the day, from 3-5 hours, if that suits you you may want to consider e10, bear in mind e10 can be more expensive than e7 rates and fewer providers offer it.

Hi,

I’ve been with Ebico on a pre pay meter for E7. They have been using SSE but no more so looking to change.

SSE have this on their website:

“With Economy 10 you get one meter which has two rates. It’s not usually suitable for homes with gas, oil, or electric storage heating as it’s designed to work with electrically heated wet radiator systems.” https://sse.co.uk/help/electric-heating/economy-10
Is this correct that E10 is not suitable for storage heaters as they have told me this before and the guy installing the storage heaters said it was b/s…

Also I’d like to stay with a supplier who is eligible for the Warm Home Discount worth £140pa.

Any suggestions welcome.

Hi Pat,
I can catagorically state that OVO are not able to install an E10 meter which will send a signal to our boiler leting it know when the 10 hours off-peak are. We paid an electriction to install a timer at the boiler end, and voila! the boiler now uses 70% off-peak.
By the way, we have some friends on a scottish island who instlled solar panals and there meter went backwards. After lots of research we found out this was because the meter was antiquated and didn’t have some sort of ‘stop’ peg on it. Their elec. supplier just changed it to a modern meter and it now works fine.

Hope this helps.

Can you tell me if OVO did replace your meter? We have Eco10 and when we fitted solar panels the meter started going backwards and Eon put in a supplementary meter which registers the stored heat usage which also means we only get 5 hours Night rate as opposed to the full 10 hours ‘cheap rate we had previously.

I have just spoken to OVO who want to charge a double standing charge because we have the supplementary meter. Their standing charge is already double what Eon charges but if OVO can supply an E10 meter it would simplify my mathematics if nothing else.

Hi Mark,
Many thanks for your clarification. A word of caution for everybody. We are moving into an apartment with an ElectraMate 2000 hot water system. Printed on it is ‘please ensure this equipment runs with Economy 10’. The same meter has been in place for 12 years (since the flats were built). It would seem that the previous owners were operating on the basis of an E10 tarrif (putting dishwasher on etc.) but were being charged for an E7 tarrif. Goodness knows how much extra they were paying. In fact when we purchased the property the then owner and the Estate Agent informed us that everything ran on the E10 tarrif.
We use OVO in our present property and are going to use them in the new property. They have already agreed to replace the meter with the correct E10. They were also very pleasant whilst working through the problem, unlike EDF.

[adminKeymaster]

Yes that’s correct. The time switching is built into the meter, so E7 and E10 are physically different bits of kit.

[ChrisParticipant]

Hi Mark – thanks for your reply. I understand that the two tarrifs are different. However, EDF are saying that the actual meter, the equipment itself, is different for the two tarrifs. Is this true?

Chris

[adminKeymaster]

Hi Chris, yes Economy 7 and Economy 10 are two different meter types. The E7 gives you seven hours off-peak overnight. E10 is ten hours off-peak split into three blocks across the day.

There’s lots of info here:

Hi Mark,
We are moving into a flat which has wet elec. central heating. I’ve just telephoned the current supplier EDF, who very clearly stated that based on the meter serial number we gave them they are adamant that the meter is an Econ. 7 NOT an Econ. 10.
Can this be correct – is there a different meter for 7 or 10 – I’m totally confused.
Any help would be appreciated.
