Green light showing on meter but not able to add credit?

I'm pay as you go and have just gone to top up, but the metre is only displaying the green light with no credit etc? I've put the key in and nothing, pressed the blue button and nothing. Im worried that I'm going to end up in darkness with not knowing when the fault started? We did experience a power cut a couple of weeks back. Can anyone advise? I've rang over and they're only accepting emergency calls such as no supply.

Ah yes… As I suspected…

Your meter has gone into Free Vend Mode due to that recent power cut. You temporarily have “Unlimited Credit” until the meter gets reset - but you’ll need to pay back what you use later. You will NOT Self-Disconnect in the meantime.

Please have a word with OVO Support in the morning, they’ll make the arrangements to get an engineer out. Given the age of the meter however, I’d definitely suggest migrating to a Smart Meter anyway - it’s due to be replaced soon as the cert on that one is running out.

Welcome to the Forum ​@Richie 57!

 

Sorry to hear what happened to your meter. Did you contact OVO this morning following ​@Blastoise186’s advice? You can find our number and online chat link here.

 

You might find it easier to have a smart meter installed, free of charge. This will allow you to top up using our app, so you don’t have to go to the PayPoint. You’d also then be able to swap over to be a pay monthly customer if you’d prefer.

Mone is like this now, did you try and top up or not? I didn't know whether to put money on the key or leave it till the engineer comes out, my appointment is booked 2 January

Morning ​@mandileek, I hope you’re well, and just tagging ​@Richie 57 so they see your reply on the thread.

 

Sorry to hear about your meter ​@mandileek. It’s likely that any top ups you make aren’t going to actually be recorded on the meter properly, as it’s faulty. If the meter goes off supply please call us straight away, and we’ll get an engineer out within 3 - 4 hours as an emergency to get the meter replaced. You can find the emergency contact details below - hopefully shouldn’t need them.

 

 

I’m also going to include below some PAYG smart meter articles, so that you can get an idea of how it will work when your smart meter’s installed. It’ll make your life a lot easier for sure! You’ll also have the option to move over to Pay Monthly, if you’d prefer (it would mean you’d never risk going off supply).

 

 

Lastly, some important information: If there are any vulnerabilities within your property that will be a risk if you go off supply, we’d recommend signing up to the Priority Services Register. This is a free service with numerous benefits, the main one being that you’ll receive notice of a power cut where possible, and will be put back on supply by the Grid with priority, should there be an outage in your area. You can find out more, and sign up, here: https://www.ovoenergy.com/register-for-priority-services.

 

Cheers!


I have the same problem with my electric meter. We had a short power cut on Tuesday. The display screen on the electric meter is now blank ( only noticed this morning). Phoned OVO to report after trying to press blue button/hold blue button and putting the key in to make it work. OVO are coming out to install a smart meter soon. My question is what happens to the credit I had  built up on the meter before the power cut happend ?

If you know how much you had on the engineer will put it on your new meter. Ive still got supply and thank you to the lovely people on here they made me aware of the free vend mode which will keep your supply on but pop the money to oneside that your using at the moment to pay the debt off when your up and running again

Do not adjust your sets! This is not an invasion - your resident evil genius Blastoise is up to late night mischief again… Totally nothing to see here… Honest Guv!

Just a heads up…

If the meter is responsive to the engineer programmer units, it may be possible to read and “backup” the remaining credit/debt balances before the meter gets taken off the wall. Free Vend Mode usually allows for this - but only an authorised programmer can interrogate the meter to find out. And I don’t have one myself (nor do I have the encryption keys either) so I can’t help there.

Otherwise, it has to go to the lab.
