Hi,

When I moved here in 2018 there were already Liberty SMETS1 electric and gas meters installed so I’m not sure how old they are. Since then no-one has been to check them ( they are both inside the kitchen ) and I’m starting to wonder if the gas one should be replaced due to age of battery. Should I contact OVO to request replacements ?

Hey ​@alt 

 

I’m glad to see one of our volunteers Blastoise186 has already stopped by with some really helpful advice already. 

 

As suggested, the meter will signal when the battery is low, as well as the meter having a set date in which we’ll need to have it replaced for overall safety purposes (we call it the meter certification). If the meter does start to approach this, we’ll be in touch to schedule in an exchange.

 

If it’s still doing it’s job of sending us readings over then it’s still working as it should be and that’s a good sign!

 

If for any reason, even if the meter was brand new, and the supply was cut off, we’d get someone out to fix the supply and meter if faulty, but it shouldn’t have to reach that point.

 

I have linked below to a topic about meter certification just in case you find that useful:

Hi ​@alt ,

Could you show us the meters real quick? I think you’ll be OK with what you have now, but I just wanted to see what you’ve got for a sec.

Hi Blastoise186

Thanks for reply. The meters are tucked away in very awkward positions in cupboards which makes it difficult to get satisfactory pics. They are the standard Secure Liberty SMETS1 100/110 meters. Since posting I’ve found a blurred date on the gas meter which seems to indicate sometime in 2017 so that makes the battery around 8 to 9 years old.

That’s what I’m concerned about - don’t want to risk a gas failure on the approach to winter.

Thanks for confirming!

You SHOULD be OK for now - the gas meter will send an alert to OVO when the battery drops below acceptable levels. And if you’re Pay Monthly, the gas won’t get cut off even if the meter battery dies - that only happens on PAYG (for which you can get an emergency engineer visit anyway).

The meter health is monitored remotely, but you’re welcome to ask OVO to run some checks if that’d make you feel better - just ask OVO Support and they should do be able to arrange that for you.

Thanks Blastoise186 

We are on pay monthly so it’s possible that my fears of a gas cut-off are a bit paranoid.

Thanks again for the advice.
