I had a smart meter installed 2 weeks ago and since then my storage heaters and immersion element to heat up the water in a big cylinder tank are not working anymore. Both only run on off peak electricity. I have raised this with OVO, an emergency engineer, a commissioned engineer, came but couldn’t solve the problem. Since then I’m daily on the phone with OVO but nobody is able to help. I’ve raised a complaint, got a call from OVO and was told that my case is being looked into and I would get a call back. Nobody was ringing back. It’s very stressful to call daily, explain the same problem each time and not getting anywhere. I was even told by one operator that it’s my problem and not OVO’s.. It’s absolutely outrageous that an organisation like OVO is not able to rectify the problem. I wonder if someone had similar experience and can give advise how to handle the matter. Thank you

First thing to try is ask the Support Team to reconfigure the ECAUL/ALCS Configs on the meter via SMETS Commands.
Please post photos of your setup, it may help a forum volunteer like myself figure this out.
Also, it’s not going to speed up your case if you keep smashing them to pieces every day. Please try to be patient - someone will be in touch when they can.

Sorry to keep on posting.
I'm so confused by this email OVO sent me earlier today.
Rang OVO just now, was put on hold after telling my details, line failed 2 X. After ringing the 3rd time the operator said the earliest appointment will be the 6th December.
Have the remote checks done to attempt fixing my off peak problem and that's why OVO sent me this email?
Or has the smart meter not communicating with OVO nothing to do with my storage heater problem?
The only thing I heard from OVO today was the email.
Sadly, the operator couldn't help much with these matters. He also couldn't transfer me to the person ringing me yesterday evening.
What I'm supposed to do?
I really can't deal with this anymore. It’s 4 weeks this Saturday.

That’s shocking. You must be wishing you had never tried a smart meter! As a storage heater user myself, there’s no way I would agree to having a smart meter until there’s a guaranteed system set up for those of us in this position.
Will they not even agree just to reinstate what you had?
I really feel for you.

The only way is onwards, there is no turning back. Once a Smart Meter is installed, there’s no downgrading back to Traditional - especially not back to RTS Meters.
I’d say go ahead and book that request to get the ball rolling. This feels like a specific case of a dud meter rather than anything to do with the Smart Meter stuff.

Nobody ever asked if I had storage heaters before installing and I would have never thought this could be a problem.
Perhaps I got the hint and try to find a malicious electrician…
Anybody knows if a privat electrician is able to fix the smart meter? They won't have access to OVO I believe? So in my mind that doesn't work?

Nope, no electrician will touch the meter if they want to stay alive.

Did you get an IHD with your smart meter? If so, is it giving you any useful data? If it is, you could check whether your usage data are getting through to DCC; if they are, the ‘communication’ problem is at OVO’s end for them to sort out.
We’d be happy to guide you through the steps to check this out - just say.

Yes, Ovo arranged for a partner engineer to come and he is changing the smart meter to a heritage meter as we speak. First he tried to commission the smart meter but that didn't work.
After 4 weeks without heating and hot water hope all will be working smoothly.
Next battle will be to get compensation and refund for 2 engineers not turning up.

Glad to hear they got someone out to you to get this sorted.
How have things been since the engineer visit? Are the Storage Heaters and hot water working as they should?

That’s excellent news! I explained to the advisor on chat there are many customers experiencing issues like yours. They don’t inspire confidence do they. But perhaps this means OVO is listening, at least to this forum. I shall keep a watching brief!

Hey
I’m sorry to hear you had issues with your billing. I’m glad that our Support and Billing teams were able to work together to resolve this issue for you. Moving customers from THTC setups to smart meters has been an evolving process, and sometimes hurdles come along, but we’ll always do our best to resolve them for you as quickly as possible. I was sorry to read that the experience has let you to consider switching suppliers, and as sad as we’ll be to see you leave as a customer, we also believe in the power customers have to pick and choose who supplies their energy. I’d strongly suggest waiting 6 weeks from when your smart meter was installed to ensure that all your new meter details have been updated with the relevant DNO, as if you request a switch too early into this process, it could cause some issues.

You’re right. Many customers are facing issues, as it’s been a challenging process getting customers off old THTC setups onto newer smart setups. Hopefully, this will start new opportunities for customers historically blocked from tariffs/switching and better benefits. Sadly, in today's world, you mainly hear about the negative experiences and rarely the positive ones, and while we can put our hands up and say we do make mistakes, we can also celebrate the wins when they come.
If you have any follow up questions or need support let us know and we’ll do our best to help 😊

Hey
I wonder if my heated discussion had any bearing on the alteration in my online account a few hours later?
The operative I spoke to was, she claimed, unable to help, but would pass the problem up the ladder
I was also informed that her supervisor would be unable to help because the supervisor was not trained in the procedures?????
My impression remains that CS is a joke!
Where in the world the call centre is situated I do not know but the operative appeared to have difficulty understanding the English language although she masterfully avoided directly answering questions!
I would suggest that Mpumelelo would benefit from additional training or if she meets your standards perhaps the whole dept is in need of examination?

The operative I spoke to was, she claimed, unable to help, but would pass the problem up the ladder ...
Customer support is of variable quality in my experience, so you’re not alone in your frustrations. However, I have on two occasions been told something similar and then discovered that the problem I was concerned about went away within a few hours.
It’s a pity, but perhaps understandable, that when a problem lands on the desk of someone in a position to do something about it, he will do what’s necessary as soon as he can. He will probably have too many problems to deal with to give him time to email or call every customer to explain what he’s done, assuming he has authority to do that. I suppose that, all things considered, this doesn’t matter nearly as much as actually having the problem solved, as happened in your case.

My problem was blocking my switch to another supplier!
The removal of the false figures was necessary in order to remove the block.
The cause was the OVO system patently ignoring the readings from the smart meter and somehow conflating the old two meter system with the replacement system and a flawed bill production system
Obviously the problem was easily solved once addressed but the underlying problem is that of getting the problems to the attention of someone with the skills and authority to take action.
If only 2% of THTC changeovers hit problems getting satisfaction for the vast numbers involved would I believe indicate that the present inadequate CS function needs major revision
The outsourced call centre CS depts are a relatively new phenomenon which I never knew in my 60 plus years in business however when they exhibit problems they should be reviewed and the problems attended to!
I am leaving for a supplier with a better record for CS and an economic pricing structure
Good luck to all those in the multi meter trap!

If you are correct in saying I should have been automatically shunted to special team then it would seem that we have just identified another failure in your system
I should not and no other customer should be made to run around in circles trying to get a problem solved
I still have not had the promised telephone call from “The Resolver”
It seems your systems need some attention sooner rather than later

My problem was blocking my switch to another supplier!
A THTC meter exchange is an immensely complicated process. It isn’t just like having a new starter motor fitted to your car so you can sell it tomorrow - there are many actors involved. For a start, all the various bits of OVO and its subsidiaries (commercial, billing, smart, website admin, for example). Then there’s the electricity distributor and, important for those keen to change supplier, the national database that provides the information prospective suppliers and comparison sites need to be able to make informed decisions. Updating the database can take a long time.
It may all happen quickly, but some installations could well take weeks to settle down completely. That’s why you will have heard about the six-week period after a meter exchange during which OVO aim to have everything in place. You may be trying to jump ship before it’s out of the harbour.
I am leaving for a supplier with a better record for CS and an economic pricing structure
Would you care to tell us which supplier? Other customers may well be interested if you’ve found a reliable option cheaper than what OVO are offering.

Hi all,
Apologies a bit late to the feed but I have the same issue as OP (except I gave in to OVOs letters and had my Smart Meter installed in 2022).
I’m on an Economy 7 tariff and some of my storage heaters are wired up to off-peak only supply. I used to hear a clunk in the flat each night and morning when the supply changed over but that doesn’t happen any more. I believe that was linked to a timer in our meter cupboard downstairs sending the signal to our fuse box to switch on/off the off-peak supply.
The winter of 2022 I discover the storage heaters aren’t working and they send an engineer out but they say nothing wrong with the meter and the Support team say my meter is configured correctly and won’t sent the ECAUL command to update the ALCS config as they said there’s nothing wrong and it’s my issue… they just keep fobbing me off. My neighbour has also had a smart meter installed and their storage heaters now don’t work either (though they aren’t that bothered as they use a portable heater around the flat).
Pictures of my old and new meter attached.
I’m not really sure what to do from here :( any help would be much appreciated!
