As far as we know, Ovo Energy still supports Economy 10. Please post specific questions or updates below. [- May’21]3rd July 2015 at 8:28 am #1531StevePParticipant
When I contacted OVO regarding a ComfortPlus White Meter with three readings and two MPANs, here is what they said:
I can confirm that we would be able to supply your duel MPAN economy 10 pre-payment meter.
You would just need to fill in the relevant section on our quote and switch page, to let us know that you have two related MPANs, otherwise there could be a delay in switching.
However, as you technically have two supplies registered for this meter, there would be two sets of standing charges which could prove to be quite27th November 2015 at 4:40 am #1532GrahamWParticipant
By the way, after years of tearing my hair out with SSE, I decided not to go with the absolutely lowest-priced supplier but to factor reputation for good service into the choice as well. It’s early days but OVO seem to actually know what they’re doing!
I would publish my usage and cost charts since 2010 if I could work out a way of doing it.18th March 2016 at 6:06 am #1533GrahamWParticipant
I strongly believe, having tangled with SSE on numerous occasions, that reputation and customer service are also important when looking for a supplier. SSE score nil in those areas and are also expensive. OVO are not the cheapest (although their Economy 7 on my Economy 10 meter is 25% less than SSE’s Economy 10) but their reputation and customer service is exceptionally good.8th June 2016 at 9:50 pm #1534ChrisParticipant
We moved into an all elec. flat a year ago. Since then we have been trying to get OVO to instal a meter wich sends a signal to our Gledhill hot water boiler when the cheap periods occours, (so that it can heat its thermal store on E10 rate). After 4 meters installed by OVO then finally admitted that their installer does not fit this type of meter! EDF do but their rates are prohibitive.
How does your boiler turn on in the cheap periods?
Chris Keating15th August 2016 at 4:58 pm #1535NickParticipant
Have you got an Electramate 2000 thermal store? You should have a separate switching circuit which is run from a normal 13A supply. Forget the meter, that can be connected via a time switch so it activates at the E10 times and heats the water to 85C rather than 65C. If you look on page 10 here you’ll see “off peak signal supply” on the rhs of the diagram. That’s what you need to sort out.20th August 2016 at 10:27 am #1536ChrisParticipant
Many thanks for your reply. Just in the last couple of weeks we’ve been able to fit a separate switching circuit as you quite rightly suggested. Since we moved in I’ve been taking a weekly reading to understand our usage and as soon as the switching circuit has been installed we are using a lot higher percentage of low peak electricity, as expected. Just an asside, OVO tried to fit a correct meter four times and did not know their insallers could not supply an automatically switching meter.
Thanks for your help.

Chris, are you sure OVO are supplying E10? When I spoke to them last week (I was thinking of changing, hence landing on this site) they told me they only actually supply E7 whatever the meter type and you’ll get charged the peak rate at the other two times.20th August 2016 at 11:15 am #1538JohnHParticipant
I have two adjoining properties- both all-electric with recent E10 meters that only give TWO readings. One has been with OVO for some time and I’ve just moved the other one from EON to OVO. Although officially OVO say they don’t support E10- if the meters are already in place then they treat them as E7. (i.e. ALL the rate 4 (off peak) consumption is priced at the lower rate.) Eventually the meters will get changed to “smart-meters” and I expect to have some “discussions” then as I do need the cheap daytime rates to make it work (I can’t run washers and dryers in the small hours.)20th August 2016 at 2:14 pm #1539ChrisParticipant
Yep, I’m sure I am on an E10 tarrif. (I can say this with confidence after the blood, sweat and tears I’ve epended!) The OVO meter only records two rates (peak and off-peak). The meter is set up to switch at the regular E10 times and has a sticker on the front. I checked this by taking readings in all six bands whilst using electricity to see which of peak and off peak were changing, and the meter did perform correctly. I’m not normally this obsesive but the whole area of E10 has got me so mad (swear word, swear word!) We have a Gledhill Electramate which should receive a signal from the meter to start using off-peak. Sadly, OVO are not able to supply this type of meter. EDF do, but at more expensive rates. In the last few weeks we have had fitted a time clock to the boiler which simply sends a signal to the boiler to start using off-peak. It works a treat and last weeks reading showed 73% off peak usage.

We were with Eon and switched to OVO.
Because we already had an Economy 10 meter, they let us use it on their Economy 7 tariff (we still get 10 hours off peak).
OVO prices are [31% cheaper peak, and 23% cheaper off peak]
We have wet electric central heating (great if you are on E10 and disciplined) and expect our annual bill to fall by about £200

Great job Mark!
Having switched from SSE to Ovo just over a year ago, I can well understand the latter’s quite high customer satisfaction ratings. They are not the cheapest but I think it’s well worth taking more than money into consideration when choosing suppliers. My experiences with SSE (who were and are more expensive) were farcical.13th December 2016 at 7:16 pm #1542TonyBParticipant
Went onto E10 18 months ago and E.on supplied meter. Switched to Ovo last July.
Both Ovo and Eon good to deal with and quick to respond. Sorted out a billing error quickly and satisfactorily.
Thanks for all your hard work Mark.

Yes I’ve always had consistently excellent service from Ovo as well, hope they keep it up!30th January 2017 at 3:31 pm #1544LizBParticipant
Great blog-thanks for sharing your research with us-it has been such a difficult process trying to find E10 suppliers in the past. We shall follow you avidly now!
Just a point of note, and I know that prices evolve all the time, I have been chatting to suppliers today, and on the basis of your work looked at OVO as a strong possibility. The daily standing charge on a 1 or 2 year fix is now quoted as 28.77 which presumably means they will drop down your chart as they will now work out much more expensive….13th February 2017 at 5:08 pm #1545Nancy
Yes, I have just today been quoted  by OVO. They also wanted to charge me 2x standing charges as I have 2 supply numbers into my 1 x E10 meter. Would that be right? I argued that it was only 1 meter and he said that could be adjusted to 1 charge, but I wondered if he was correct.
At the moment I’m with Npower using theirE7 tariffs who are just putting up their prices.21st February 2017 at 12:20 pm #1546JohnHParticipant
Thanks for all the efforts you have put into this site!
As a result of many problems with EON (see my previous posts) I changed over to OVO (with two adjacent properties) Both are now on OVO’s better Energy tariff but at significantly different prices to your quoted rates. Both properties have E10 metering and no gas. I use the “online” option providing regular meter readings and only email contact for any queries. 
I understand the increasing consumption prices as the wholesale prices have increased BUT the SC is much higher than your figure(s) adding about £55/year to each property??
In general OVO have been much better to deal with than EON but their standing changes seem rather higher than I would expect- any idea why?
Ware, Hertfordshire.13th June 2017 at 3:53 pm #1547PatParticipant
We changed to OVO in May in direct response to Eon’s extortionate price rise and got a two year fix . Ovo do not support E10 but will allow the use of an E7 meter. The only problem with that is that they will not replace the meter if it becomes faulty but as Eon had just replaced our meter, after a lot of hassle with split supplies etc, we took the rate. OVO’s standing charge is 28.77p/day which I had to consider in my calculations – time will tell.
OVO have now offered me a smart meter together with V-charge. As we have solar panels does anyone know if fitting a smart meter would be to our advantage? Also V-charge?; I can’t work that out at all in relation to E10. Also Immersun? any advise would be welcome.22nd August 2017 at 7:06 pm #1548LorraineParticipant
 Note very poor contact centre with Our Power, although much cheaper quote, plus you leave them your details and they have to contact you to switch – they didn’t call back!22nd August 2017 at 7:06 pm #1549LorraineParticipant
 Ovo Energy website from search says they currently do not operate Economy 10 tariffs.14th September 2017 at 2:15 am #1550MichaelParticipant
OVO energy accept E10 customers on their E7 tariff, you can sign up online and just select e7 as your meter type, they confirmed this to me on twitter.Hope that helps.28th September 2017 at 10:28 am #1551MKingParticipant
Anyone with OVO? We have been spammed their free Internet-of-things based app control which purports to control the supply of electricity beyond the basic hours switching. The system is not yet but on E10 but OVO’s website says it will be soon…
Apparently OVO has bought the company that makes the device(s)…
We have never left the rads on for the whole 3-sessions and the OVO device promises to make this easier to do; it definitely saves money as, unless one is ‘in’ all-morning, the first (overnight) 5 hours can be a waste of heat that has dissipated by home-time from work… We find the most useful session is the 3 hours in the early afternoon which provides for homecoming and early evening. The last 2 hours are a boost for colder days and by using a ‘normal’ heater instead of the storage the 9-11 hours (8-10 winter) period has immediate effect (and in winter powers the electric blankets on the cheap)…
We signed long term with iSupply (3 yrs) but OVO might force a change….21st March 2018 at 5:02 pm #1965Mark_E10Keymaster
email received from OVO 21/3/18:
Thank you getting in touch. I hope I am able to answer your queries below.
* Yes we support Eco10 meters but on Eco 7 rates but these are split to different peak and off peak hours throughout the day.
* The cost to have an Eco10 meter installed is £57.75 for a single phase meter and £99.75 for a three phase meter.
* We do take on ,ore complex Eco10 meters however we may not be able to bill the customer in the way that they had been billed by the previous supplier. This depends on the TPR (Time Pattern Regime) structure.
* Any Economy 10 meters installed by Ovo via Lowri Beck will have one supply and one meter with two registers, one for peak usage and one for off-peak usage.
I hope this has been of some assistance to you.

Have now been with OVO on a fixed price deal for nearly 2 years. Prices not the cheapest but not bad – service and communications good. Would recommend them as a company.
Using a Thermaflow all electric wet heating and hot water system which is saving us around £300 a year compared with our previous oil fired system.2nd September 2019 at 12:31 pm #email@example.comParticipant
According to their site
OVO no longer support Economy 10
Does OVO offer an Economy 10 tariff?
The short is ‘no, not at the moment’ – this info exists here purely because we like our customers to feel informed about different energy options.
