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.

What do they refer to as I need to enter them & I am not sure which boxes are relevant.

 

That’s a very good question, which I was rather hoping wouldn’t come up. TOU Rate 1 should be the peak rate register , while TOU Rate 2 is for offpeak - but we have seen cases where they were the other way round. To be sure, tomorrow morning take a pair of readings at, say, 09:00. Then another pair an hour or two later. The one that has increased is the peak register. If it’s not TOU Rate 1, I think there’s another change that OVO will have to do remotely when they decide they’re able to. I’ve got my fingers 🤞🏻crossed for you!

Hey @connorsbjc 

 

Sorry you’re still having some issues, but I’m so glad to see Firedog is helping you through a lot of this.

 

If you’d be able to do what Firedog’s suggested in the last reply, you’ll be able to tell which is the peak and which is off-peak.

What do they refer to as I need to enter them & I am not sure which boxes are relevant.

Keep us updated with this and how you get on.

Thanks I have sorted that bit now.

Tou 1 is Peak.

Was again in contact by phone with Ovo this morning to find out why they haven’t yet done the reconfiguration of my meter remotely after a week. I eventually got the advisor to understand my problem & she went to a colleague & came back with the answer that they didn’t have all the details of my meter & will have to wait until they do. What details do they need one wonders ?

I am going to go quiet now for a week & see if there is progress .

I am paying approximately 50p day more for heating than I should,which is acceptable for a short period,hence the reason I am pushing them to get the meter reconfigured.

At least they got that bit right!

That sounds like a good plan. Meanwhile, if you have switches for your heating equipment, you could try for the time being having them on only during the night (would that be 01:00 - 08:00 BST for you, or some other local E7 variant?). It might not work as well as having the daytime boosts, but it could save you those 50p a day ...

Thanks.As it stands now this is my scenario.

The power to the heaters is only available to me between 1am/8am, of which 4hrs is the peak.

I only switch the heating on for the 1am/8am period,but usually get up by 6am to turn it off early.

So in the few hours the heating is powered it gives me enough heat for the day.

Those few hours after 1am the power is on is where the 50p extra comes in so I can’t avoid it.

The only concern I have is not knowing when it will all be corrected.

Maybe my next post will have good news 🤷🏼‍♂️

Not had any more news from Ovo in the last 2 weeks with regard to my meter issue.

BUT, just had an email from them to say my meter is not sending readings & they are sending an engineer.

Apparently he is going to change the meter 🤷🏼‍♂️

I can only hope that is the problem, if not we begin again.

Does anybody know a way of escalating this beyond advisors who read from a script ?

Hey @connorsbjc,

 

Sorry to hear this,

 

I hope that the meter exchange resolves this issue. If you’d like to escalate this further there is the option to raise a complaint

Hi still got a problem OVO don’t seem to know how to fix. OVO changed my THTC meter to Economy 10 on 4th September.

They wrongly commissioned the meter to Simpler Energy on1rate.  Contacted OVO and the Resolutions team the next day and they have just managed to change the tariff to Simpler Energy Economy10, yesterday 21st October. 46 days to change Tariff. 
Unfortunately for me the storage heaters are not getting a charge at Economy 10 off-peak times. Been in contact today to tell them and once again they can’t give me any solutions to how they are going to fix this. It’s getting cold here in Dundee Scotland. 
I have had 2 engineers out to look at meters and wiring, both from England who say they are not

familiar with THTC, Economy 7 and Economy 10 tariffs and can’t fix my problem. 
I see other people have similar problems.

Hi Noz1954.

Join the club.

My new meter will be replaced again on Thursday but I have my doubts about the results.

I am supposedly on Eco 9 but my heating comes on at 1am at peak rates & nobody has done anything about it.

So much incompetence in one company
