Total Heating Total Control Tariff
I found out by accident that the digital teleswitching for this tarriff will be turned off in March 2023. SSE (now Ovo Energy) have not informed me of any change, presumably because nothing is definite yet. I called them today to find out what my options are. I am currently paying £450 per month which covers our 7 storage heaters and hot water - a household of two retired people. When the house was new 28 years ago our bills were £110 per month for a 4 person household!
OVO have told me not to worry and that they will come up with an alternative and I will probably go on to a timed tariff. However, my concern is that on a timed tariff I will lose the THTC boost to the heaters during the day and is essential during the winter months to keep the house warm. This question could not be answered, only that a smart meter would solve this but as yet they are not available for THTC heating system. Turning off the signal will therefore result in a colder house which is a worry. I am therefore trying to think ahead as it looks like I will need to invest in a new heating system. Another call to their tariff team suggested changing my meters to an Economy 10 system. Has anyone changed from THTC to an Economy 10 tariff? Has anyone retro-fitted ground source heating?
I feel totally at the mercy of SSE(Ovo) as there is not competition for the THTC tariff and turning off the teleswitching will leave me in the cold.
Thank you for reading and all advice gratefully received.

This would be best in the energy forum.This change has been in the pipeline for many years now, I am surprised that you are surprised by it happening. You really need to get your metering changed to E7 (or maybe E10) and would need an electrician - at your cost - to look at your current set up and advise on what, if any, wiring changes may be necessary, again at your cost. THTC has not been competitively priced for a long time. And yes you will lose the daytime boost.0

TD;DR: Ideally change to high heat retention NSHs such as Dimplex Quantum and switch to E7. You can then choose any supplier you like. In reality you can probably change a few and move other around, perhaps ending up with eight or nine if you have the space but want to keep the costs down.Fully Monty: The March 2023 date is probably just a bit of a scare story. THTC and similar Restricted Hours Tariffs are a pain because they are expensive, there's little or no competition and they're being made massively expensive or being phased out. Your teleswitch is probably updated by the Radio 4 Long Wave signal on 198kHz. The data contract was due to expire earlier but has been repeatedly extended, and may well be extended again. We were all supposed to have smart meters by now but that's slipped by five years, and the teleswitching contract may slip similarly as well.Even if the data signal is switched off, IIRC the teleswitch will still switch at the same times, just like a digital watch will still show the time if you stop checking it against the Greenwich Time Signal. Teleswitching just stop it drifting, and can vary the switching times by +/- 15 minutes (at least on E7).Unless you do something dramatic such as switching to LPG or a heatpump, the answer is probably to increase the storage capacity and then switch to E7. Some old storage heaters needed an afternoon boost because they were too small by modern standards, but energy was ultra cheap back then. Modern high heat retention ones are more efficient because less heat is given out during the night when it's not needed.0

Out of interest, what are your current and standing charge rates?
