THTC meter has to be replaced with a heritage Economy 7 meter before a smart meter can be installed - what can I do?

We are trying to get a smart meter installed to replace our THTC meters.  We have been told by engineers who visited yesterday that, in order to get rid of our THTC meters, we need to change to a heritage economy 7 meter first then we can swap to a smart meter. Is this correct? We have storage heaters and need to keep an economy 7 type tariff. Getting in touch with OVO to get this heritage meter is proving difficult!!

I see.

In that case, if you want to move now then the method OVO is suggesting is, unfortunately, the only option that I can think of myself at this time.

The upgrade path in question would keep you on THTC with Smart Meters. If you no longer need THTC, then going down this route wouldn’t be the right move.

Update on RTS shutdown:

 

As part of the RTS Project development, we are really happy to share with you our progress:

 

As you may be aware, the RTS signal that instructs some of our meters when to move to the “Off Peak Period”  will be closing down soon and we need to arrange for all of our RTS customers to have a meter exchange so they don’t lose any of their meter functionality.

 

The RTS signal will end for our customers on 30 June 2025. The period between 1 July - 30 September 2025 will then be used to close-down the RTS signal and allow us to manage any unexpected customers impacted.

 

After a very successful pilot, from the 17th of June 2024 we began writing to our Economy 10 RTS customers to invite them to call us to arrange for their meter exchange. 

 

We are continuing to work at pace to enable the same solution for the majority of our other RTS customers.

 

We will continue to update you on our progress.

Hi @Cassie511 ,

I’m a forum volunteer here.

What was the reason you needed to remove THTC? If you still have a need for it, then you’ll need to wait as an upgrade path is still in development.

We want to remove the THTC to get a smart meter. We have solar panels and an electric car. We are exporting loads of electricity and are being paid nothing. I was really wanting confirmation of what we were told yesterday...is getting a heritage Economy 7 meter, then swapping to a smart meter the recognised way of doing this?? It feels like we are being fobbed off by everyone we have contact with. I have read your comments about the upgrade path which is in development. Have you any updates on when this is likely to be available?? Thanks.

Thanks for your help. It is much appreciated. There appears to be considerable confusion around THTC. It has served us well for many years but is now very expensive and an out of date system.
