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.

Thank you. I actually asked the advisor why he couldn’t do the ACLS for me & as previously mentioned was told to disregard this information on the forum.

As I do have power to the heating overnight but at the Economy 7 timing , I have no clue as to the rate per kw they will be charging. 

Hard to believe this is the 21st century

Well ! Progress possibly.

After many hours another Ovo advisor has agreed that it can be done remotely when the account is updated to the new meter. When is an unknown. May get it done or may have to try again.

Also had a scare with a bill for £1750 on my online account for 1 months power.

Pleased to say it was sorted very quickly by the advisor on chat & I can relax again.

Life is too short for all this OVO hassle.

Hey @connorsbjc 

 

Glad to hear things seem to be sorted out now, do let us know if you’re still experiencing any issues, or any in future.

 

Sorry to hear about the trouble with the bill too but I’m glad that’s been sorted too, without knowing too much it sounds like it’s probably had something to do with a meter reading somewhere along the line that the Support Team were able to fix. Glad that was sorted for you quickly, I can’t imagine that was a nice shock, and as you said life’s too short for hassle - I couldn’t agree more there.

 

Hopefully that’s everything resolved now but do feel free to pop back to the Forum any time if you’ve very got a problem or question, we’ll be here to do our best to help.😊

Hi Abby

Thought it was too good to be true. My online bill ,which was updated online yesterday to the correct figure of £130 for September ,has disappeared & the original bill of £1750 is back up. I have been onto Ovo and they say it will take a while for the account to be updated to the new meter.

Pity I can’t upsticks and get out of this mess of poor billing & wrong meter settings,only a matter of time I think.

… another Ovo advisor has agreed that it can be done remotely when the account is updated to the new meter.

 

That’s a new excuse I haven’t heard before - I wonder what it means?

I got my fingers burnt in a parallel case yesterday - of course, remote commands can’t be sent to a meter that’s not in communication with OVO, and communication may not have been established straight after the meter exchange. 

One signal you can check yourself is the state of the LED indicators on the communications hub on top of the meter. When all is working as planned, these two green lamps should flash at five-second intervals. What are yours doing?

Both are flashing as you say. Meter still operating on 2 different tariffs, why can’t they send the signal immediately to change the heating to eco9 ?

Judging by the figures on the IHD the overnight tariff is way up. Last nights heating shows as 12 kw for £3.80

That looks painful, but you can’t base any decision on what the IHD says as regards costs. The £ figures you see there can’t be relied on.

OVO will be charging you full whack (27.39p/kWh) for your usage 01:00-03:00 and 06:00-08:00. Usage 03:00-06:00 should be at the offpeak rate (21.16p/kWh). The £3.80 will include £0.63 for the standing charge (62.93p/day), so the electricity has apparently cost £3.17, which is only a little bit less than what 12kWh would have cost at peak rate (£3.29 - £3.42).

It could be that, having switched on at ~01:00, your heaters were more or less fully charged by 03:00. Three hours later, they decided to take more charge - so you missed out on much of the offpeak slot. This sort of thing won’t happen once the heaters are being switched on and off at the right times.

 

Both are flashing as you say.

 

That’s really good news, because it means that your meter is in communication with the network and so with OVO. Have you checked your online account in the past couple of days? Once communication is established, it might take a day or two for the billing system to catch up, to record the new meter (whose serial number (MSN) you noted a couple of days ago) together with its opening readings and any subsequent ones received.

You may also be able to see half-hourly usage data on the usage pages; if you can’t even though the MSN is now the right one (shown on the readings page), check on this page that the account is set to receive half-hourly data.  

Once that’s all settled down, it will be time to contact support again to persuade them to get your meter configuration updated.

So it seems that my heaters only come on in the night between 1am & 8am but I am paying the Peak rate for the power until the meter gets switched over to eco9. Not much I can do in the short run but pay up

Thanks Firedog.I am now looking at sending readings.I have taken  2readings. Tou rate 1 & Tou rate 2.

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

I do check the online account regularly & the heating to see if anything changes. Nothing so far. I appreciate your input very much,it’s helped me navigate this mire and get some peace of mind 👍
