Switching from British Gas to OVO Using Current BG Installed Smart Meters?

I am considering switching my electricity & gas supplier from British Gas to OVO. I currently have a Smart Meter which was installed by BG. Would this meter continued to be used by OVO (i.e. it wouldn't be necessary to install a completely new meter by OVO)?
If it would continue to be used by OVO, would it be necessary for OVO to change the method of communicating meter readings ( Ithink BG receive reading via mobile phone technology)? Assuming that OVO will need to do something to link my Smart Meter to their systems, would manual readings have to be submitted until such time that the alteration was made?
Thanks in advance

Updated on 07/07/22 by Jess_OVO: 

OVO supports British Gas S2 meters so as long as the meters are in communication when you switch these meters would still send the readings automatically when you join us.


If your British Gas smart meter was installed before the summer of 2019 it will likely be an S1 smart meter. These meters were not originally compatible with OVO, however the Smart Data Communications Company (DCC) are currently in the process of remotely upgrading these to work with all suppliers, like an S2 smart meter. You can check whether your meter has been upgraded using this online tool.


All S1 meters should be upgraded by September 2022. Switching to OVO before this upgrade happens will mean your smart meter will function as a traditional meter and you’ll have to read the meter manually in the meantime. Got a Landis and Gyr meter? Check out the guide below for help taking this reading manually:

Hey @bertimcg I've moved your question here as @CityFlyer already found out the answer!

We have a great 2 year fixed deal at the moment, and as soon as you are on supply you can arrange an appointment to get ours fitted for free so its pretty straight forward.

Here's the link if you decide to go for it. It's worth checking out:

Hello all,

New user to Forum and new to OVO. I hve a BG smart meter fitted and wondered what will happen to it when I switch suppliers shortly.

Will continue to work with OVO supply or will it be redundant?

Hey @mfaz Welcome to the forum!

I have moved your question to this topic is its something another user already asked. All the info you need should be on this thread but if you need any further help or advice get posting below.

@CityFlyer nailed it in terms of where the industry is right now, in the future smart meters will be much more compatible, but for now, you'd need to submit readings manually or sign up to get new meters fitted.

Hope this all helps!

Right now most energy companies can't read each other's smart meters remotely, it's usually the case whoever you switch to. The meters still work, counting your energy etc, they just can't communicate...

OVO will problee be delighted to fit you with a shine new pair of smart meters for free. Had mine done in January, and they're bloomin' marvelous. The engineers were really nice too...
I have just switched to Ovo from British Gas. British Gas installed smart meters and an in home display earlier this year, will these be working as smart tech still now I have switched? Thanks.

I'm looking for the answer to this question too? Thanks
I have just switched to Ovo and they are asking me for opening readings. My previous supplier for both gas and electric was British Gas and they installed smart meters for me. Why do I have to submit meter readings to Ovo now when I presume they have access and can pull the information directly?

If its just an opening reading then fine but will I have to continue giving readings?
Hi, I move to ovo on Monday. I have smart meters installed my BGas (landsis gry e470) installed about 6 months ago. Will these work with ovo?

If not can ovo install me a new one?

Also do they charge?

Let us know if you need any further help, or feel free to reach out to another user on this thread for more advice. You can @ them in a reply or comment if you'd like to ask them directly.

Interesting reading so far...I have a few questions:

What do I do with my current BG smart reader?

Will it still work / provide accurate usage? (apart from cost due to tariff changes)

Can BG still access my information / usage details?

Will OVO install a new one for free?

What are the differences between OVO and BG smart readers!!?

Phew...hopefully someone can give specific answers opposed to a generic answer from the Community Manager :)

Welcome to OVO @markd

I have moved your question here, there are few customers already asking about this and the answers have been pretty much covered so this should help you too.

Get posting below if you have any other questions or queries. Both myself and the mods, plus the users I'm sure will be happy to help further.

I also have a British Gas smart meter fitted. I see from this forum that to get the full functionality that I would have to have this changed to an Ovo smart meter. A couple of questions then:

1) If I decide to keep the BG meter, will this still continue to work to give meter readings that I can then use to update my account with Ovo ?

2) If I decide to update to an Ovo smart meter, what happens a couple of years down the line if I decide to switch supplier again - do you have to keep having new meters supplied with every supplier ?!
I've recently switched to OVO from British Gas. British Gas Installed Smart Meters for me a year or so ago and I am now hearing that OVO cant use these. Is that correct?

I'm just coming back to OVO after a year with British Gas (Dual Fuel). While with BG I had smart meters installed and and in home device which have really helped me save energy.

Will these devices work when my OVO supply starts.

Best wishes

Hi @Janee Thanks for signing up to our forum!

I've moved your question here as the answer is above on this one. In a nut shell, no your current British Gas Smart Meters will not work when you switch over, but we can get you booked in to get OVO Smart Meters installed so you can continue to benefit from this.

If you have any other questions, please feel free to post.

Hope that helps.
