Moving from THTC to another tariff- Will all consumer units be connected by Ovo to the new meter ?

We have THTC with consumer units for Storage heaters,fixed appliances & lighting/mains.

Will we be able to move to Economy 9 when the new meter is installed ?

Will all consumer units be connected by Ovo to the new meter ?

Can the power be delivered without being on a timer so we can manually control the heating.

Would like some idea of where we from here & whether the future will be more expensive.

Thanks

I can answer those for you.

When you contact OVO to arrange the migration/upgrade, you’ll be able to discuss the available tariff options. If Economy 9 is offered to you, feel free to select it. Otherwise, you’ll need to go for one of the options that does get offered. This will be done before any work is carried out. They are best placed to advise on costs.

OVO will migrate all wiring between the existing main fuse, meter and consumer units over to the new meter and reconnect everything. However, everything beyond the consumer unit(s) is your responsibility.

Per the terms of E7, E9 and E10, the meter must control the timings. You’ll be welcome to use the Boost function if you need a top-up though - but use of the Boost function would be at Peak rates.

One final thought.

As my heating only operates at eco7 times but I am paying for electricity on eco 9 times/rates,would it solve the meter switching problems if they moved me to Eco7 tariff immediately which in theory would synchronise things ?

Not knowing the problem this is just my speculation. Probably worth trying for a response from Ovo

Sadly, I think that would make things worse at this stage. Your account with all its multifarious facets is still in a state of flux, moving from one complex metering and tariff arrangement to another, so any further change could only confuse matters still more.

 I’d be inclined to let matters rest until it’s all settled down. Keep an eye on the things that are not yet in place, and when the six-week point arrives, make a careful note of them all and put it to Support, preferably in writing so you all have a record of what is still outstanding. One item, for example, is the second MPAN, relating to a meter probably languishing in the back of an engineer’s van.

If you’re seeing half-hourly usage figures, do your sums to work out just how many hours have been charged at the higher E9 overnight rate while the storage heaters and water heater have been running during E7 offpeak hours, and tot up the usage figures. (To be fair, you should also work out how much electricity you’ve been using at E9’s cheap rate during the day, but keep that under your hat for the time being. It’s probably trivial by comparison, anyway.) The overnight figures could form the basis for a claim for compensation - it’s OVO’s fault, after all. 

Since your heating is on all night (during E7 offpeak hours), you’ll be getting a good idea from the usage data of how much electricity it’s consuming. This will give you a basis for working out which tariff is best for you. You should then be able to tell whether E7 is right for you. Shout if you need a hand with the calculations!

Details above you suggested I try on the account.

The Mpan was the one I have noted & the meter number is correct.

Thanks again

That is really interesting, but I’m not sure what conclusions we can draw from it, if any. I wonder if this is a temporary set-up while things are being sorted out.

This is what it tells me, for what it’s worth:

  • tier: null. This will normally be a number like 0, 1 or 2. The lower one should be for the peak register, the higher for offpeak.
  • timePatternRegime: 14007. This says what times the meter should switch between recording on the peak usage register and on the offpeak one. The information I have - which is very possibly outdated - suggests that this code is unique to OVO. It only gives a lot of offpeak timings (107 hours a week!), but indicates that there is a related meter involved. That would be the heating meter, now sadly deceased.

 

I’m afraid I’m inclined to ignore the whole file for the time being, because it doesn’t appear to relate to your current situation. Pity!

On your reading history page, are you seeing both peak and offpeak readings? Are they incrementing as you’d expect, or are you perhaps seeing a lot more peak usage?

Both readings showing once daily correctly & incrementing normally.

Resigned to a long wait but will claim refund for the Peak heating hours at some stage.

My bills are fairly low so not too concerned in the short term

Seven weeks now and no progress on my meter issues. Paying Peak rates for my heating isn’t much fun as the days get colder.

Another billing problem cropped up too 🤷🏼‍♂️ my latest bill only covers the standing charge & not the electricity I have used, despite daily reading being logged.’

About to contact the Ombudsman to see if they can help.

Getting tired of this. Wondering if Octopus would take me on

Did you contact support once the magic 6-week deadline had passed? They should now either be able to have your switching times reconfigured to what they should be or tell you why they can’t. 

The ombudsman won’t be interested until eight weeks have passed from the date you entered a complaint without having it resolved. I don’t think you’ve got that far yet ...

Waiting for a reply from Ovo complaints department.

As I first complained on the day the meter was installed on 3/10/24 there is just 9 days left before I contact the O/man.

Using just one 3.4kw storage heater at the moment & my calculations, from complex daily readings of the kilowatts, show I am paying approximately £26 month extra on the wrong tariff.

Have requested a refund until the meter is fixed. Will post again when there is progress

I’m afraid there’s quite a difference between calling support and saying something’s not right and submitting a complaint. If a complaint has been raised, you would have been given a case number and eventually the name of a complaint handler, who would then be responsible for seeing the process through to resolution. I’m not sure that you’ve been through this mill; I rather thought you’d been told early on that it could take up to six weeks for everything to fall into place after a meter exchange. Now that you’re beyond that deadline, you have grounds to enter a formal complaint. When you do that, OVO have eight weeks to sort it out. If they don’t manage within that time frame, then you can refer the case to the ombudsman.

Thanks for that information.

I did raise a complaint about a month ago .I was contacted by email but no case number given.

The Account Management Agent said my issue needs to be investigated by an engineer & he would let me know when a time slot was available. That was the last I heard.

So getting someone to actually take notice and then do something positive is a bit of a lottery.

So I will make sure I get a name & a case number this time.

Was not aware of the 6 week deadline ,but it’s no matter now.

Thanks
