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

Hi @connorsbjc ,

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.

Having problems uploading pics as they seem to be too big.

Wrote an explanation to you but it disappeared.

Will try again

We had our Thtc meter changed last week for a meter on eco9 tariff.

The eco 9 tariff works ok on the house consumer unit changing tariff 3 times a day for 3 hrs.

The power to the storage heaters only comes on at 1am until 8am ,which is the timing for Economy 7.

Also the rates on the meter do not match those of the plan

Still cannot upload as the files are too big.How can I reduce them ?

The photo of the meter screen was at 1-15pm today.

The off peak times are GMT. 3 to 6 am,  12 to3pm , 7.30 to 10.30 pm

Thanks

As a result of this forums help I got onto OVO this morning to ask for the Reconfiguration of the meter.

The answer I got was “ kindly disregard this information “ from the forum .

They are (hopefully) sending an Engineer to look at the meter

Thanks everyone for the input but think it’s time to sign off & pray 🤷🏼‍♂️

I stand by my word - OVO Support agents shouldn’t be telling folks to ignore the Forum advice. We know the solutions well at this point.

I’ll let the Forum Moderators know.

 That’s very helpful, thanks.

Good. That means the TOU table has been properly set up (my point (2) above).

Not good. 13:15 BST is 12:15 GMT, so I would expect* the offpeak circuit to be live at that time. The meter screen shows in its bottom right-hand corner that it’s not: the little o´o symbol labelled ıı means that the second contactor (ıı) is open. When the circuit is live, it should be the same o¯o as you can see for the first contactor (ı). 

This most probably means that the ALCS is not properly set (my point (3) above). Contact Support and ask them please to get the smart team to send the ECAUL request to your meter to configure its ALCS to Economy 9 timings. 

 

Also the rates on the meter do not match those of the plan

 

The rates on the Plan page are shown ex VAT (because that’s what you’ll see on your bills). The ones on the meter and the IHD include VAT. Is this the difference you see? 

26.09 > 27.39 inc. VAT 
20.15 > 21.16   -”-
59.93 > 62.93   -”-

If they’re more different than that, ask Support when you contact them to have the correct tariff as shown on your plan sent to your meter. The tariffs and costs you see on the meter and the IHD are for guidance only - they aren’t used for compiling your bill.

Someone might ask you for the meter serial number (MSN), because that’s often the quickest way to identify it. Make a note of it so you can quote it readily along with your OVO account no. The MSN is shown above the barcode above the meter’s display screen, starting with 22M. 
  

*   The offpeak start times will probably be a bit (in theory up to 30 minutes, but normally not more than 10 minutes) later than the ones specified. This delay - specific to each meter - is to ensure that the distribution network isn’t overwhelmed by thousands of multi-kW heaters all being switched on at precisely the same time. To check the state of the circuit, then, wait until 45 minutes after the switch time before looking to be sure.

Very helpful. You are right about the rates,they are correct with vat added.

I contacted support this morning asking to reconfigure.The agent told me to disregard this information & is sending out an engineer 

Will he be able to do it physically when he comes ?

I think I’m right in saying that all he can do is call HQ and ask for the right commands to be sent to the meter. In other words, there’s nothing he can do that the support agent wouldn’t have been able to.

However, he may be able to check that the configuration update worked - but only if it worked there and then. We’ve seen many cases where the command had to be sent more than once before the change actually took effect. It’s easier with Economy 10 than with Economy 7, because a physical check can take place in daylight. With E7, the physical check would have to be done after midnight (in some cases after 01:30!) or before 08:00 (or even 07:00). 

With a reasonably competent customer on site, I’m sure this engineer’s visit could have been avoided, allowing him to get on and exchange somebody else’s RTS meter. They’re going to struggle to meet the 30 June deadline as it is, without scarce engineering resources being expended on what appear to be unnecessary tasks.

Just my possibly ill-informed opinion, of course 🙂

Hey @connorsbjc 

 

I’m really sorry to hear about the experience you’re having with this.

 

Sadly by the sounds of things, an engineer won’t be able to do anything in this case, and a simple remote command should fix this. 

 

We’ve seen this quite often off the back of 5 port meter exchanges and I can’t say I’ve seen an example where sending an engineer was the fix when the heating or hot water isn’t working following these installations. 

 

We’ve got a few topics on this already:

 

 

As Firedog mentioned, the engineer can contact the Support Team while on site to have the commands sent, and wait to see if they work as they should, but other than that, it’s unlikely he’ll be able to do anything as it’s probably not the meter itself that’s causing the problem.

 

Do keep us updated with how you get on.
