Revisiting after a few hours off, I see that we may have overlooked something. I have referred to ‘the meter on your wall’, but now I’m wondering if that is in fact the case. It’s common for meters in blocks of flats to be located centrally, often in the basement. If your meter isn’t actually in your apartment, where is it?

We’ve seen many cases where flat-dwellers are told which of many meter is theirs, only to discover later that in fact it was someone else’s. It’s not difficult to sort that sort of confusion out, but it can take time. However, if your meter is inside the flat, this sort of crossed-meter scenario is really unlikely.

@oaashy1411 good morning, I hope you’re well.

 

I’m sorry to hear that you haven't had the most helpful service from OVO since reporting this. It sounds to me as if a complaint has not actually been logged. If it had have been, you would have been provided with a complaints reference number, and you’d have been assigned a complaints handler. The fact that an advisor booked you in for a meter read appointment shows that they must not have understood what’s going on with your account.

 

I’d recommend getting back in touch to log a complaint. When you get in touch, advise that you tried to log a complaint previously, but were never provided with a reference number. Also, request that the Metering case number is provided (a case will most likely need to be raised to our back-office Metering team to get this looked into).

 

We don’t have access to customer accounts on the Forum, so can only speculate as to what’s happening, but it sounds to me like this just hasn’t been logged correctly. This is a really complex one, and sometimes these sort of queries just need to be logged correctly as a complaint in the first instance, to ensure that it’s sent to someone with more experience. Please keep us updated as to how you get on - we’ll continue to help as much as we can here.

 

@Firedog thanks again for helping so much on this one!

I did raise a complaints email on the 27th a few hours before I got the call from the agent to arrange a visit. After the visit on the 5th turned out to be just a meter reader, I sent a follow up email forwarding my original complaint.

However, the only item I have received back is this automatic email to my original complaint on the 27th - so no reference number/dedicated handler at the moment.

Interestingly, the reading taken by the meter reader has so far not shown up on my account which makes me wonder if that was done just to establish there is an actual problem.

@oaashy1411 I’d definitely recommend getting back in touch to request that the complaint is raised properly. If it had have been raised, you’d have received a complaints reference number by now. 

 

You could either email hello@ovoenergy.com, or contact us via social media which might get a quicker response. You can reach us on Facebook and Twitter.

 

Please keep us updated as to how you get on, cheers!

I’ve emailed the complaint line forwarding my original two emails to them to ask for an update/the complaint to be logged and also to check in due to the lack of response from them following the meter reader’s visit. Have also cc’d in the general queries email - so hopefully someone eventually replies. I have indicated I’ll escalate it to the ombudsman on 22 January if there is still no communication or there is not sufficient progress looking at my meter.

Is there any potential reason why the complaints team have not logged the complaint or emailed me back?

-First emailed general queries line: w/c 24 November

-General queries line replies and states they will pass my query to the metering team to look at: 26 November

-Also emailed the complaints line to get it registered: 27 November

-OVO get in touch via phone call to book in an engineer visit (I assume this is from the action from the general queries line): 28 November

-Engineer turns out to be a meter reader: 5 December

———-

No further contact received from OVO

———

-Sent a follow up email to the complaints line with no response: 5 December

-Sent a second follow up email to the complaints line: 14 December

Will keep the forum updated and see if OVO get back to me.

Many thanks for this! I received a call today from Tom - an amazing complaints handler. He has understood the issue in full, has given me a reference number, and will be in touch to sort a proper engineer visit.

A big thanks to the forum for all of you helping me along with this.

… Tom ... has understood the issue in full, has given me a reference number, and will be in touch to sort a proper engineer visit.
 

It’s a bit sad that it took a kick from a forum mod (an ex-member of a support team, I think) to get Complaints to spark, but I’m glad someone has taken ownership of your case at last.

Just a word of caution: many customers and indeed support agents seem to regard meter engineers as wizards, relying on them to fix all manner of ills. Of course, much of what they do appears as wizardry, but there are some problems that can’t be solved by an engineer visit. I’m not convinced that yours can, I’m afraid, and I’d rather have done a bit more investigation first. It might help to have done this before the engineer visits. The questions I would have asked are:

  • Where is your meter physically located?
    -  inside your apartment;
    -  on the wall outside your apartment, alone or with others;
    -  in a communal utility room, e.g. in the basement; 
    -  somewhere else?
  • What is its MAC address? (That’s the GUID starting with 00-1C-55- … printed on the meter above a barcode);
  • Do you know who lives in the apartment formerly known as Plot 307? It’s possible that there’s just been a straight swap, which would be much easier to unravel than a daisy chain around the block … 
  • Have LMAM been able to track down the the meters that the two similar MAC addresses belong to in their records? (One ends in -03-64-69, the other in -03-65-4C)
  • You will probably be asked to perform a sanity check on your meter, so you could try this in a quiet moment. Here are instructions I found but forgot to note where:
    •  Arm yourself with a good torch, then turn lots of high-power stuff on in the flat - plug-in heaters, immersion heater, tumble dryer, oven, kettle, toaster, iron etc. 
    • Find the meter with the serial number shown on your bill and look at the red LED marked nnnn Imp/kWh. It should be flashing rapidly. 
    • Unplug all sensitive electronic equipment and switch everything off again. Then at the consumer unit (“fuse box”) throw the master switch(es) off.
    • Go back to the meter and watch the red LED for a couple of minutes, to be sure it’s not flashing at all. On some types of meter, it may just glow solid red; that’s quite normal if everything the meter’s powering is switched off. I don’t know whether your Kaifa MA120 does this. In any case, it shouldn’t flash at all with everything switched off.
    • Turn the master switch(es) on again.
    • Finally, you could do a quick accuracy. I doubt there’s any problem with precision, but you could test it by plugging in just one item of known high power; a full 3kW kettle is ideal provided that you're quick enough to complete the test before it boils. Back at the meter, count the number of flashes N per minute to calculate the power P kW being drawn. For example, if the LED is marked '2000 Imp/kWh,' that is the meter’s EMP: P = N x 60 / EMP. You'd expect to see about 100 flashes per minute: N = P x EMP / 60 or 3 kW x 2000 imp/kWh / 60 mins/hr = 100.

  
These checks should establish whether or not the meter you think is yours is actually measuring the electricity you’re using in your flat.

  • If it is, OVO seem to have the wrong meter recorded on your account.
  • If it isn’t, the meter measuring your usage is somewhere else.

My guess is that LMAM are the ones best placed to find the source of the problem and suggest how to put it right. Another possibility is Kaifa, since there’s a suspicion that two meters apparently have the same serial number. They should know which MSN corresponds to the specific GUID. I’m not certain that your OVO contact or a visiting meter engineer will go so far as to call LMAM or Kaifa.

The physical meter reading is what matters for your actual bill. If the app is lagging, it’s usually a signal issue. You might want to run the 'Smart Meter Health Check' in your OVO online account - it’s a quick automated tool that can tell you if your comms hub is actually talking to them properly.

The engineer visited today and was very helpful. His diagnoses of the problem was that the communications hub is reporting via radio frequency… But because it is deep within the building and may have a weak signal, it is giving slow and inaccurate readings.

He is going to book me in to have a new 4G communications hub fitted to my meter which should give accurate readings. I did ask about the MAC address mix up and it potentially being connected to another address in their database, but he thought this unlikely.

Even then, a new communications hub should fix the problem anyway I think as I am guessing it’ll have to be registered/its own unique details added to the database.

This looks promising, but I have some misgivings …
  

His diagnoses of the problem was that the communications hub is reporting via radio frequency… But because it is deep within the building and may have a weak signal, it is giving slow and inaccurate readings.

This sounds unlikely, so I wonder if the engineer was paraphrasing a bit for your benefit. The comms hub is just that - a device to communicate, in this context passing data from the meter to the supplier. Each packet of data is time-stamped, so there’s no such thing as ‘slow readings’. They might not always turn up at OVO’s end as promptly as everyone would like, but your data are being received as the very first support agent told you.

The remark about inaccurate readings is more worrying. A smart meter - even a Kaifa - is a precision instrument, warranted by the manufacturer to measure within the prescribed limits for precision. There have been very few cases that I’ve heard of where readings have been inaccurate, and they all involved gas meters. The meter measures, and stores the measurements for a long time. When OVO wants data, a request is sent by their data processor via the DCC to the comms hub and on to the meter. When everything is working properly, the meter coughs up the requested data and pushes them back to the originator by the exact same route, in the opposite direction. It would be a very serious matter indeed if a data packet that the supplier received had contents different from those sent by the meter. Any hint that the packet sent wasn’t kosher would simply result in a null (= no data) value being received. 

That said, I would hope that fitting a new comms hub will get your meter working properly again, so long as there’s a decent 4G signal where the meter is 🤞.
