I've moved into a property, it's top up- Why has the credit gone down already, I've not used anything?

Hey ​@Tee1,

Have you received the keys for the property? If so, you are now liable for any energy usage. As ​@BPLightlog mentioned, daily standing charges are applied and likely caused the balance to fall. More information can be found in the guide provided and i’ve left more information below:

What is a standing charge?
 

A standing charge is a daily fixed charge that goes towards the cost of supplying energy to your address. It includes the cost of the pipes and power lines, and maintenance of your meters. You pay your standing charge no matter how much energy you use – even if you have a smart meter.

Why do OVO plans include a standing charge? 
 

Because we use a standing charge, we don’t have to use structured unit prices like other suppliers do. We believe our way is honest, transparent and much simpler.

How do other suppliers cover this maintenance cost if they don’t use a standing charge?

All suppliers have to contribute towards these maintenance cost so it’s likely they will include this as part of your unit rate (which might be higher).

Obviously the impact of a standing charge cost will differ depending on whether you’re a high or low energy user. If you’re comparing plans we’d advise finding out your Estimated Annual Consumption (EAC) figure and entering these under the ‘Do you know how much you use?’ question on our Quote and Switch page.

There’s more details on understanding energy tariffs on this great guide.

Hello. I want to register a new electricity account for my house. How should I do that? Thanks.
 

Are you moving in as a new owner or tenant?

Or are you wanting to switch supplier?

The articles here should tell you how to go about either one; but please come back if you can't find your answer there:

Hey ​@Jinling,

Just to confirm, have you recently bought or moved into a new home & want to register your name with the energy supplier?

If so, Chris & Nukecad have porvided helpful links here. Or do you refer with regisering a new electricity supply with your current home? In which case, this topic might be helpful:
 

Let us know if you have any further questions 🙂
 

I can't register my account. I didn't receive any mail from the supplier. Now how can I get the reference number? I am currently using a key to pay for my energy.
 

Hi ​@Jinling ,

You need to call 0330 175 9669 to get set up if you haven’t already.

As you have a Key Meter that runs on PAYG, you cannot use online services.

Is there any way to register online.My English is not very good.Thanks

Possibly. Try Live Chat via https://ovoenergy.com/help

But as you’re PAYG, you can’t register via self-service at this time.
