THTC / Separate Radio Teleswitch and Meter- Can I get a smart meter?

Hoping someone here can help because this has been an on-going battle since before OVO took over SSE and it’s gotten progressively worse recently. 

I live in a house that’s meters haven’t been checked, inspected, whatever since at least 1993.  I have two meters - one for my storage heaters and water tank, and one for standard electricity.  I’ve been trying to get this changed to either a smart meter if available OR just a standard single meter with a day or night rate. 

I have email chain(s) going on with SSE/OVO (One email chain is using @sseenergyservices.com and the other is @ovo.com hence posting here) that I seem to just be going around in circles.  I finally got through to the Electric Heating Team (EHT) about two weeks ago who changed me onto a single rate THTC tarrif, so both my standard and heating meters are at the same rate - but based on the readings that I’ve been providing, it’s still nearly 500 a month just for two storage heaters and a water tank.

Has anyone else had problems being switched to a single meter?  It’s driving me insane and I can’t change providers even if I wanted to because I’m currently bent over a barrel with an old meter system that they won’t change that no one else supports.

 

Edit: Just to add, it’s Radio Teleswitch Total Heat Total Control (THTC) to be specific.

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 June 2024 we will begin 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 and our aim is to begin writing to these customers in Aug 2024. 

 

We will continue to update you on our progress.

Hey @Noz1954,

 

I don’t know the exact figures, I’ll see if I can find out. I’d imagine a few thousand as Blastoise advised.

 

We’ve had a couple of customers on the Forum who’ve advised they have THTC set ups, would be interesting to get a conversation going. 

 

 

We’ve got an FAQ on exotic types which might have some useful information:

I just need this issue of 2 meters to be solved and have just one smart meter and one distribution board (I understand changing to one distribution board will be at my cost).

 

I do not see why you need to change to a single distribution board - my father has 2 boards now - was 3 and shower was separate. You would only need a single meter with a set of tails supplying each board. 

Although if your boards are old, changing to a modern board is a huge advantage from a safety point of view, and when I installed solar - i had a new additional consumer unit fitted which also houses the solar meters.

Hey @metalsman 

 

As Blastoise186 has mentioned, we’re working hard on a replacement and will update all impacted customers and any related topic threads as soon as we have more information on this.

Thanks @thelearner for sharing that, the safety element of the upgrades in this situation are a common theme with old boards so that could be really helpful. I’ve also given you a badge for the solar set up you mentioned having.🙂

Thanks for the information @Abby_OVO but its the lack of even basic information of the proposed new arrangement thats annoying eg will it be a single meter? how many tails from the smart meter? my present set up has 4 tails from the meters for heating, 24 hour heating, water and domestic plus 2 neutral tails into my distribution boards.

I dont need to know the exact details of the proposed new set up for the meter and tariff just an outline of how many feeds (tails) will be coming from the new meter(s) to my distribution boards to allow me (and I suspect many others) to move forward with my solar panel and battery installation.

I can’t reveal the exact info yet, but the current plan is to make it all into a single meter with enough ports to be a drop-in replacement.

While I’m twiddling my thumbs waiting for the Ofgem 8 week period to pass...You’ve now posted a bit more info about the THTC replacement solution. Will this solution allow customers to come off the THTC arrangement (Economy and Heating Load tariff in our case) and move to a single meter arrangement?

As a reminder, I’m ditching the storage heaters to move to an A2A heat pump. Existing arrangement is 2 consumer units, one for storage heaters, second one for everything else incl immersion (immersion on economy 7 timer), second consumer unit fed through a twin white meter that supplies peak and overnight off peak elec.

Or will I still need to get the feed to the storage heater consumer unit removed completely from the supply?

Why are you even complaining anyway? It’s already been stated many times that you cannot be moved from THTC yet and the even the Energy Ombudsman knows that.

But yes, the solution would move things to one meter IIRC. Can’t promise about coming off THTC though - that’s up to the DNO, not OVO.

Thank you. I have 4.4kw of SW facing panels in NE Scotland with a Give Energy 3.6 inverter and 9.5kw GivEnergy battery, delighted with the performance - not great for me in winter with low sun as I get afternoon shading from my neighbours high roof, but in March my net cost for Electric was £0, and sorry to mention them in here - but that’s mainly due to Octopus Agile Smart Tarrif and charging battery cheaply and 15p per kwh for my exported solar. Last summer I made money for export most moths and fully supplied our needs (no EV or ASHP so not high usage)

The complaint is that OVO don’t have any process or support to enable customers to enable them to move away from THTC, effectively locking me into an expensive tariff for a replacement, much more efficient, heating system, ultimately OVO will be costing me money when we move to the new heating system.  

Previously SSE were offering Smart meters to customers who arranged and funded the wiring mods themselves, OVO seem to have no similar process or advice except for offering the THTC replacement, which even then might not give me what I’m after.

What does it have to do with the DNO? the property isn’t in a LMA.

Home Energy Scotland has the below advice, so clearly its been possible previously? I know of others who have done this but its helpful to have a documented case.

Sigh… I’ve said this before

This is not an OVO problem - it’s an industry problem. I fail to see how punishing OVO via complaints will do anything here. I also KNOW that the solution is coming that’ll unlock the next move.

OVO didn’t create the problem - it was dumped on them.

The previous supplier had a solution, OVO don’t, simple as that. This is about customer fairness and value, as well as implementing a heating system to help reduce emissions.    

Surely the THTC solution was a distinct part of the contract arrangements between SSE and OVO, yes, OVO didn’t create the issue, but they knowingly took on the task, hardly what I’d call being dumped with it, all contracts have their upsides and downsides.
