Why is the tariff rate on my smart meter and Chameleon In Home Display (IHD) wrong?

The standing charge and kWh rate on my Chameleon IHD are higher than my account tariffs . My Account tariffs are correct, any way to correct the IHD display? Thanks.

Good spot on the mis-match between your unit rates on your online account and Chameleon In Home Display (IHD).

It’s worth checking whether the discrepancy is just due to the VAT*. Your OVO online account will usually show your unit prices excluding VAT whereas your IHD may show the same prices including VAT - if the difference between prices is 5% this will explain things.

 

*The government is cutting VAT on household electricity prices from 1 October 2026 to help with the cost of living. So this issue should be irradicated in regards to VAT causing such a discrepancy, so if you spot one, please do reach out to the Support Team

 


The tariff information on your device may need to be updated. It may be that you’ve recently had the meters installed or your prices have recently changed and the rates loaded on to your meter haven’t quite been updated. In this case reach out to our Support Team to get that corrected. It is worth bearing in mind the following:

 

Usage costs on your IHD may not 100% match your daily charges

 

As the prices loaded on to your smart meter and IHD aren’t automatically linked to the rates on your account, inaccurate prices seen here won’t affect the accuracy of your bills. For this reason we’d always advise checking the actual usage charges on the ‘Billing’ page of your online account, if you’re worried that your IHD is showing incorrect information.

 

If you’ve got a Pipit IHD but are seeing the same issue - check out this topic for more advice.

Hi, can confirm OVO have fixed the fault and re pinged the display with the new price details. All working fine now. Really great customer service from OVO.

Hey ​@Marty666 

 

Thanks for the update, I’m really glad the team were able to get that sorted for you no problem and the service went smoothly. Really glad to hear that.😊

Every time the price cap changes, my IHD fails to update the pricing it is using, and so the on-screen value is incorrect. I don’t always get onto it straight away but when I do eventually get to it I have to fight with online support for ages, when I already know what needs doing to fix it. They just need to send a tariff refresh message to the smart meter.

 

If I go through online chat for support, they seem to be completely unaware of the possibilities to fix this relatively common issue. And I have to argue with them for hours to get them to fix it. I’ve done it three times now over the last couple of years. The third one, today, was a failure. They basically cut me off after doing an IHD remote reboot (which I know for a fact will not fix it; can explain how I know if anyone needs to know that).

 

Am I even talking to the right people using online chat? They seem like they don’t really have much knowledge about the system they are supporting, and it’s very hard to get them to do anything other than follow a basic script. If that fails they just find a way to end the chat and you’re left high and dry.

 

Is there a UK contact I can use for stuff like this? It’s a simple tariff refresh request as far as I can tell. Nothing more than that.

Hi ​@ric355 and thanks for your post. I hope you’re well.

 

I’m sorry to hear that the IHD tariff update is often delayed. This is unfortunately an issue across the whole industry. When a tariff is changed the IHD should update automatically, however this can often take weeks to happen. 

 

My advice is, next time this happens, to send an email to customer services via hello@ovoenergy.com. In the email say something like:

 

Since the price change my IHD is not showing the new rates. Please could you run the SMETS2 command ‘update tariff configuration’ via the bol platform, as this will fix the issue.

 

If you send this email any of our advisors should be able to pick this up and get it sorted for you.

 

My recommendation is, if the advisor says it can’t be done, or does something incorrectly, to then raise a complaint. You can then refer back to this complaint if the same issue happens again.

Does it also applies to the Variable Simple Energy plan?
