Hello, I have two meters, one for standard electricity and the other which connected to a radio signal meter. I have two consumer units, one for standard electricity and the other for storage heating which I do not have. The consumer unit which is connected to the radio meter has a large sticker on it which says PERMANENTLY CONNECTED. This supply although from the radio meter never goes off. I have underfloor heating and hot water which runs from this consumer unit and is on all the time apart from when the room thermostats switch it off. Would I need to smart meters. Is this setup correct. Thank you all.

Hey ​@Confused358 ,

Based on what you’re saying… I think you’ve got a THTC (Total Heat Total Control) setup - with this type, certain heating sources are allowed to run 24/7/365 at a reduced rate. This is not a recommended option if you no longer have Storage Heaters and Immersion Heaters - it’s probably costing you more than it should.

You will need to swap for a Smart Meter to resolve this. Support for ALL RTS Meters are being phased out over the next couple of years and the shutdown process has already started - some areas of the country have already had RTS Services disabled for example.

I’d suggest having a word with OVO about this and see what other tariff options might be more suitable for you. But before you do that, can you post some photos of the meter setup real quick? If you can, I might be able to give more accurate advice.

Thanks!
