Why has my usage doubled since my smart meter was installed?

Got it, thanks. You actually had a pretty expensive tariff previously as Superdeal is horrible value these days - I suspect your account is still being updated at the moment but it should kick over to your new tariff within the next few weeks. If it doesn’t do so within six weeks, please let OVO Support know.

The reason for the meter swap is because RTS is shutting down - and OVO has no choice but to terminate the Superdeal tariff. Please see the thread below for more details.

Let me grab ​@Nukecad too, for the number crunching (except that he Ninja’d me lol)

I suspect that what you are seeing is a combination of various things as your account is being updated, so I wouldn’t rely on what anything is saying day-to-day at the moment.

Can we assume that you chose a new tariff,  (E7,E9,E10) and not Superdeal, when your new meter was fitted?
I don’t think that you can stay with Superdeal, but I’m not an expert on this RTS changeover -Blastoise186 is the expert on that (and usually knows more than the general customer support do).

That’s correct - Superdeal isn’t supported on Smart Meters IIRC and is being fully withdrawn. You’ll get to choose a new tariff to replace it as part of this process.

​@Nukecad That you for the comments. Really appreciate it. 

I am reading £11.7 on OVO website. So you are saying it is not accurate?
 

Can we assume that you chose a new tariff,  (E7,E9,E10) and not Superdeal, when your new meter was fitted?

I believe the new meter is E7, with 12am-7am are the off-peak times. 
 

​@Blastoise186 Thanks for letting me know that superdeal isn’t supported on new meters. I believe the new one is E7.

Yeah, that’d make sense - E7 is supported on Smart. My guess is things are still processing so I’d definitely say keep an eye on what’s happening.

Whereabouts on the website?

You wrote originally “suddenly the bills have drastically increased”. If you’re looking at a figure labelled Today’s balance, that isn’t a bill. It’s just an indication of the balance on your account, taking into account what it was at the start of the billing period less the cost of your usage since then plus any payments you’ve made since then. You can see where the figure comes from on the Billing details page.

If your meter is only sending readings once a month, any consumption shown will be based on estimates, which may well not bear much resemblance to reality. Please check this page; you should ensure that at least the first half-hour option is selected, and I’d suggest that you select the second also, perhaps after reading this article: There’s an industry wide change coming to meter reading consent, and we want to share the details with you | The OVO Forum. Your meter will then start sending its midnight readings every day, and also details of your usage for every half hour during the day so you can see precisely how much energy you’re using when.  

I would update this for a few days. It was ZERO three days ago.

​@Firedog Thanks for the comment.

As I mentioned in the main comment, I paid the entire balance, and it was ZERO three days ago, now it is £16.03 while it was £11.70 yesterday!!! It is unbelievable to me! I was using this much half into the billing period when I had the previous meter. With this rate, my monthly bill would be at least £160, more than twice of what of was paying before.

Please check this page; you should ensure that at least the first half-hour option is selected, and I’d suggest that you select the second

This is what I see when I click on the link.

Great, those screenshots are from your online account so we know where to look..
(PS. I’ve asked the mods to redact your account number, it’s never a good idea to show such personal details on an open forum).

If you click on ‘Usage’ in the menu at the side of the page, then select ‘Electricity’ and ‘Day’ can you see your half hour usages?
(I have mine set to show kWh, but it’s similar if you have it set to show cost as £’s).

Note that depending on your meter, or the way it is set up, (or if it isn’t fully set up yet), you may see this instead:

Next (or if there is no half-hour usage) set it to show ‘Month’ instead of day.
We are particularly interested in the numbers in the table underneath the graph.
Are they green like this?
 

That stuff in those usage graphs and charts is just an indication of how you are using energy for your general information.

It isn’t used for your actual billing, so now let’s look at what is used for billling.

On the side menu, select ‘Meter Readings’, note any message about smart meter readings, and then select ‘View reading History’

You are intersted in 2 things here, first is it set to Hide estimates? Second what type of readings is it showing in the end column - Smart, Manual, or Estimate?

​@Nukecad Thanks.

(PS. I’ve asked the mods to redact your account number, it’s never a good idea to show such personal details on an open forum).

You are absolutely right. I removed the personal part. Hopefully, no one has noted my account number.

If you click on ‘Usage’ in the menu at the side of the page, then select ‘Electricity’ and ‘Day’ can you see your half hour usages?

I had posted it above. Here it is

Also, regarding the meter.

So you can see that I am being billed with the new smart meter.

Oops. your did it again - your MPAN is on that last screenshot.

Those meter readings are Smart and so they are what you are actually using.

The daily usage in kWh does not look excessive there. Yesterday was 8 kWh Peak and 5 kWh off-peak.

My electricity use was 4.9 kWh yesterday, and I am considered a pretty low electricity user.
I use gas for heating not electricity.

So lets apply your tariff to those kWh, let’s assume that it is still the Superdeal shown above.
It may not be - they may already be using the E7 rates to calculate your billing even though that isn’t what is showing on your account yet.

For yesterdays usage (reading received on 16 January).

£2.2928 Peak (28.66p x 8)
£1.091   Off-Peak (21.82p x 5)
£0.6747 Standing Charge
£4.0585 Total for that day
               Add VAT @5%
£4.2614 Chargable

Some days the balance will increase by a bit more, some days by a bit less, but I wouldn’t say that £16.03 in 3-days looks too unusual with that usage and that tariff (particularly in the cold weather we have just had).
