Switched supplier: Economy 7 smart meter not sending reads and IHD needs re-configuring?

Hopefully theres nothing to be concerned about but…..

Had a SMETS2 meter for about 9 months with SEB and its always worked fine, as has the IHD. Have recently been switched to OVO and suddenly Im being told my account is not getting readings

Is there a usual ‘bedding in time’ so to speak? Lights on the meter are all flashing green every 5 seconds, and the IHD usage reading are updating as normal

Yes I can supply manual readings I guess, but it rather defeats the point

 

Hopefully Im jumping the gun and it will sort itself out, but thought it best to ask

TIA

Posting here as I started a similar thread and @Firedog linked me to this.

Looking at the above and talking to OVO, I think I understand the cause of the problem and also have a possible solution albeit not an instant one, having spoken with OVO CS

The coding for the meter is switching the tariffs correctly, but the tariff number is wrong.  Tarif 1 has been linked to off peak and tariff 2 has been linked to peak.  I have just had a long but useful call with OVO CS and they have agreed this is the likely issue.  I have been asked to conduct a load test and note which tariffs change and by how much during each on / off peak section of the next day and call back with the results.

Having done that for this afternoons off peak, whilst using my hot water (draws only from the off peak circuit), the immersion heater is working and switched on at the correct time (1pm) but it is being attributed to tariff 1 for cost (peak rate) as that has gone up on the. meter and tariff 2 has not moved at all despite me using an immersion heater for nearly 4 hours now.

If you’re having this issue, it isn't going to resolve over time (unless OVO realise the mistake and update all the affected meters) so please call the CS and tell them so they can resolve the issue.  If you do your load tests in advance, note times and readings for each tariff at the start end end of each switch time, directly from the meter (not the IHD) and the tariff rate displayed on the meter at the time.

I don't think it will be. quick fix, the response form CS was once the issue is confirmed with these readings, it's an engineer visit after that but this should get the ball rolling to get the issue highlighted to OVO and corrected.

 

Hope this is of some use and helps to get this resolved for us all

Any discrepancies like this must be reported to our Support Team.

Well thanks to the ‘benefits’ of insomnia, Im able to see that with my off-peak circuit switched on, Im now being charged 77p for each hour its active rather than the £1.11 previously. Also the IHD light is back to glowing amber rather than red (which alerted me to the inverted tariffs initially)

All worth mentioning to Ovo in case I have to start a multi-million £££ complaint lol.

Hmmm I seem to have had a message ‘censored’

I posted my comments in response to an utterly stupid follow up email I received, basically telling me everything was working perfectly with my meter...this was after they “deeply investigated” my account

Well my tariff is still wrong so its not perfect.

In my original post I didnt swear, didnt name names but was scathing about the customer service I had received since I came over from SSE

Is that not allowed now?

Well thats okay then….jeez

I am utterly sick of this, so I am thinking of just switching to E7 seeing as that is what my meter appears set to

My mother is on E7 so I can see the rates she is on are cheaper than mine. However is that down to the difference between E10 and E7, or are there  differences between localities? She is in High Wycombe, I am in West London

Would appreciate any feedback

You’re both in the Southern England DNO region, in some places indicated by ‘20’ (e.g. the first two digits in the bottom line of your MPAN) and in others by ‘H’ just to maximize confusion. There will thus be no regional difference in rates, and any difference you do see will arise from other causes.

You would expect E10 rates to look different from E7 ones, simply because on E10 there are only 14 hours at full peak rate, compared with 17 for E7. The supplier has to compensate for that by charging a bit more all round, although the outcome for the average household would work out the same - that’s what the price cap dictates.

You are in effect paying more for the comfort of being able to top up your storage heaters cheaply in the afternoon, giving a bit more oomph for later on when the heat demand is highest. My E7 heaters have run out of steam by about 4 PM if they’re on all day, leading to a chilly evening in front of the telly.

Thank you….I will give them a call tomorrow and see if i can them to quote the E7 rates so I can make a decisiony

Rates Im seeing on our respective web accounts are:

Mum   29.82 / 18.71 / 47.32 SC

Me        30.34 / 22.6 / 53.36 SC

 

E7 does seem cheaper across the board, but as you say, if you factor in the number of hours you get at each rate, the difference is marginal.  Standing charge appears £22 per annum cheaper

God knows why things like this niggle me so much…..I just hate things being incorrect

Are you sure about those rates? Both sets including VAT? Both paying by Direct Debit? I’m looking particularly at the standing charge, which is dictated by Ofgem. For your region, it should be 52.19p inc. VAT, but OVO have chosen not to apply the 1 October increase. Yours should thus be 49.98p, I think. It may be more for E7 and E10 (they cost more to manage).

The Plans page is down at the moment (probably a bit of housekeeping going on at this time on a Sunday night), so I couldn’t check your figures against the available tariffs. If you’re up for a bit more jiggery pokery, you should be able to find the rates available to you on one of the pages round the back of the website: 
smartpaymapi.ovoenergy.com/orex/api/available-plans/1234567

(Remember to sign in to your account first, then access that page having put your own account number at the end of the URL instead of 1234567.)
  


[I once had a long webchat with OVO support about tariffs. We couldn’t agree about anything at all, and I was eventually able to establish that the agent was reading from not the previous quarter’s, but the one before that’s tariff tables.]

Morning Firedog

Sorry mate probably should have been more precise - the rates I quoted are ex-VAT, both lifted from the Plan pages of our respective website accounts

Dont currently pay by DD due to previous experience with both SSE and Ovo. May reinstate when current issue is sorted out,

Have gotten into the tariff section via the link you provided. Will report back once Ive found the E10 amd E7 rates that applly. That web page doesnt exactly have the relevant info leap out at you lol

 

Thanks again my friend

LOL found the info needed on that web page - my god not something you want to read through at insomnia o’clock!

Found the section for Simpler Energy E10 / On demand and the rates do match what I quoted in my post and to my IHD (albeit with 5% VAT added)

There is a difference of £75.67 in the estimated annual cost between DD and on-demand. This is a price I am currently willing to pay in order to stop Ovo jacking up my DD to absurd levels as they did with my mother….(long story). Will revisit once I feel I can trust them

Looked very carefully down the list, and whilst there are some other tariffs listed, there is no mention of Simpler Energy / E7, so cant make a direct comparison.

To summarise then, I am currently paying correct E10 tariff, but using E7 timing changes. (Only 2 changes at 8am and 1am). Its a first world issue I know, but that means Im paying marginally more than I should for the potential to have slightly chilly evenings in the future lol. Sound right to you?

With all thats going on in the world, I feel churlish even wanting to query it, but as Ive said before, things that arent right niggle me. I feel that it may be easier for CS to just change me to E7 rather than the technical team change my meter timings. Please feel free to say if you think im wrong!

Thanks again

Very last early-morning word on this today (promise)

When comparing the two “Renew Plan” pages on respective web accounts, mum gets offered a one year fixed alternative, whereas I got offered only what Im on.

Not really fussed but just wondered why?
