Smart meters

I’m trying to register with a third party to access my usage data. They ask for the MPAN (which is fine) and the MAC Address of the IHD.I’ve entered the MAC Address from the IHD I have here, but it’s getting declined. Just tried to explain this to OVO, which resulted in me being told my IHD no longer works (it does) and I can only access my usage data using the OVO App.Pulling my hair out with these folks at the moment. Does anyone have any suggestions?

Hello,What does “-A” mean in front of the meter reading ?We do have solar panels, is it something to do with that?Thank you for any help.Phil.

Have recently had solar panels installed and although I can check how much I am exporting via the main electricity smart meter I cannot see how I can see this info on my smart meter display - apparently I should see a pylon icon - have I got an old display (photo attached). Thanks. 

Eon put in a new smart meter in September 2025. We only have electricitry.  We have a tarriff with Peak and Off-Peak times.  We have an ongoing suitation where Eon constantly reverse the reading/unit cost by either sending us statements where the Peak use is actually the Off-Peak and the Off-Peak use is given as Peak use or the statements show the correct Peak and Off-Peak use but then charge us the wrong rate. They have now asked us to send photos of the meter taking “ spaced reads tests ...about an hour apart”.  I have asked why. My understanding is that with a smart meter the company can see any use at any time, possibly as frequently as every half hour. They also know what tarriff we are on  so wat added benefit will photos be ?I would appreiate any thoughts as to why Eon are seeking photos when they have the information at their finger tips.Thanks

Our Hot water tank no longer works since January this year (2026).Heating engineer checked the tank and said we must contact OVO because he reckoned OVO must have switched off our RTS signal. Twice we have explained as best we can on the phone to OVO our problem. In the first call to OVO customer services we were advised that the necessary software modifications had been made but if after 72 hours our normal Off-Peak service for the Immersion heated hot water tank still wasn’t working we should call the Technical department ( for which they gave us the phone number). After five days (well above 100 hours) the hot water tank still wasn’t working. We called OVO Technical department and were advised that everything was working at the OVO end. But how does this help if we still don’t have our hot water tank working? Can anyone suggest what to do now? 

Hello, So my plans when installing a 8kw solis hybrid inverter and 16kwh lifepo4 battery were not for export, just a protection for blackouts (the house now runs on UPS). It is also a first step to lower electricity expenses, as they will only grow when we get an ASHP. Eventually we may add some PV.  Our battery install is ready.  🙂Since our DNO uk power networks stated they would approve us to do 5kw export, taking the next step while it was all fresh seemed simpler.  I now have an export MPAN, actually with 8kw approved. Our smart meter is export-ready. But we do not have MCS nor flexorb (as I had no plan to export now, I saved the expense).  Is there an advantage to get MCS paperwork vs short-circuiting and setting up export to an utility operator that does not require it? Or is there anything to gain with MCS?  😉 

Hello!I wonder if anyone can tell me why IHD is saying gas disablement suspended?  

I currently have a peak/off peak smart meter with my current supplier for electricity with an  SSC  (Standard Settlement Configuration )  id 0939. Do anyone know is all electricity company suppliers must offer this ?  Thanks . Much appreciated

I keep getting invitations to get a smart meter and I really don’t want one is there a way to stop these invitations ? How do I make it clear to OVO that I dont want a smart meter ?

I have a smart meter and am on economy. 10 tariff. My electric underfloor heating and immersion are connected to the meter via a consumer unit connected to port 5 and the rest of the electric useage is via a separate consumer. unit connected to port 1. The meter switches correctly to energize port 5 at the proper times, and port 1 is energized 24  /7. My question is when the meter energizes port 5 and I am charged off peak rate is the energy being consumed via port 1 being charged at the off peak rate as well or is everything still split by the meter so 1 is only ever charged at peak and 5 is only charged at off peak or is everything charged at the off peak rate and then when 5 gets switched off as per tarrif the meter charges everything still on at peak?

I've had an unsolicited letter today (9/1/26) from Engage saying that my meter may not be working properly. Now I did have an old pay as you go key meter until June 2025, and it did stop working. OVO sent a letter. BUT I had a smart meter fitted later that month and since then apart from the signal dropping out occasionally (it always comes back) it's working fine. I've just topped up online via the website to check and the money went on straight away according to the hub. If there was an issue with the meter then surely the hub wouldn't register the payment, as the hub talks to the meter, not my bank card! All payments since June have gone through automatically including the £150 warm home discount. Everything is working fine! Is this just Engage having received an outdated list of old meter owners from OVO? I don't need this stress as I'm autistic and will overthink this massively. 

My Smart Meters (Electricity+Gas) were installed 1 week ago along with an In Home Display (IHD). The IHD on day 2 lost connection and I have not been able to get it back since. I have gone online and confirmed that no readings are being sent so at present there is nothing smart about it, unfortunately. The Smart meters do not come with any instructions neither does the IHD (in-built tutorial is basic only). Pressing 9 on the Electricity meter turns the digital display on (they have power saving displays) and presents the data you would expect to see on the IHD e.g. used today, used last week etc. There are no issues with my Wi-Fi. I have gone on-line to reset my browser and that doesn't work. I have used WPS and manual key entry to connect the IHD to my Wi-Fi and although it recognizes my ISP (~Sky) it is still not working. Currently, I'm unsure if it is not connected to the Wi-Fi or if it cannot connect to the meters themselves (instructions would help). IHD is within 20 metres of the

On the IHD when does the month and week start. 

I live in a 3 bed semi and have for the last 15 years. Recently switched to ovo and then had the smart meters installed .My usage has crept up over the years like everyone's. Now on OVO with smart meters and nothing has changed in my home  my monthly usage/direct debit has gone to £246 a month that's a second mortgage any ideas why my bills have double since i switched to ovo?

Hi all, I've been contacted by someone saying they are an M Group Energy engineer hired by Ovo to come and fix something connected to my smart meter, and that it's a safety issue. I've received an email showing my (correct) Ovo account number, address and mobile number. I've also had a text and calls in the past couple days. I haven't replied to anything. Ovo confirmed they have no visits planned, so I've reported the email to report@phishing.gov.uk and blocked the number. Is there anything else I should be doing? Through their chat, Ovo support said they said there's nowhere else to report this and that they would never share details like account numbers with third parties. I'm not quite sure if they make account numbers public (I'd assume not?), but I found it concerning that so many of my details were in the email. Flagging here in case anyone else has experienced this.  Lorena

I finally got my smart meter on 11th July this year - PAYG for THTC - and all seems well.Until I got an email from OVO saying they have to upgrade this meter before 31st Dec for it to keep working. Unfortunately, your current smart meter model is now being removed from the wider smart network on 31 December 2025. For your meter to keep its smart features, we need to upgrade it before then. Is this normal? Why would they install a meter with less than 6 months working life left? Do they mean a software upgrade or is it a whole new meter? It is an engineer visit, that I do know, but trying to book anything online when you have a PAYG meter is an exercise in frustration

is there any point in my having a smart meter installed as there is no mobile signal from any network where I live? Can smart meters communicate over WiFi or WiFi Calling for example?

We had a smart meter installed a few months ago. We haven’t yet been given an in-home monitor, so have to refer to the meter itself.  On checking our usage today, I noticed the meter had stopped sending daily readings since 6th of this month, which coincides with a bad storm and power outage. On checking the meter in order to send manual readings, I noticed that there were three LED status lights and, at first, the green light was showing. There were also two buttons to the left of the screen, one green and the other grey. We took a note of the reading being displayed, but since we have both peak and off-peak rates, we waited to see if it would show the other reading but it didn’t, so we pressed the green button and the display went blank. After randomly pressing both buttons, we eventually got back to the original screen, but the LED light which had been green had now changed to blue, and we’ve no idea what this means.I’ve included a photo of these lights ( please note that it is actu

Looks like I have issues with my smart meter, it’s not sending data to Ovo.I have a smart meter health check booked for the end of the week,but in the meantime, what are the consequences.re: charging at home & receiving charge anytime credits & a little help with your heating credits ?Especially as my Ovo Charge app has missing data. Tom…

Here is an extract from the table showing my gas usage yesterday evening. As you can see, two values are recorded: 8.30pm and 9pm. If usage is recorded at 8.30pm, does this show what has been used between 8pm and 8.30pm or what has been used between 8.30pm and 9pm?

I moved into property with all electric which had Smart meter 1 and economy 7 rate.Smart meter was upgraded to a version 2.I believe this was eventuallycommissioned two days later however since being fitted has not worked correctly.Instead of getting 7 hours off peak to heat water and storage heaters it comes on for 10 mins.I know this as boiler had been checked out and the boiler company tested how long off peak was being supplied.Ovo say its on the correct rate.This had been going on for nearly two weeks and despite an escalated complaint still getting no further forward.No one appears to understand what the issue is.Can anyone help.Thanks  

When we have high demand in our house (like switching on a shower), the lights go dimmer. Recently our car charger has frequently stopped working saying there is a supply problem. I’ve just discovered that we can see the voltage on our smart meter, and it goes down as low as 190V.  The highest reading I’ve seen, with virtually nothing on, was 220V. We are in a very rural area. We have storage heating and when the meter was installed we were told it was a 3 phase supply. Does anyone know what’s going on? 

I had a smart meter installed. Chose economy 7 tariff as have storage heaters and water heated by thermostat on off peak. Since meter installed off peak does not work. Ovo sent an engineer who changed the meter. Still no off peak. Ovo then said they’d fix the problem remotely. They said it was successful but still no off peak. Now they are saying it must be to do with my wiring or configuration and they can’t do anything more. Now what am I supposed to do? No heating or hot water since July 28th.
