• Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.

RTS turn off

It's trivial to transmit that to all units while the kit is still broadcasting.
True but even if that is done, the actual switching times will drift massively as the RTS devices do not have an internal clock as such, it's just a microcontroller with its internal oscillator.

scaremongering about things not working correctly after switchoff,
Not scaremongering - very likely to happen with heating switching on/off at times people do not want. Or as you have suggested, stuck in one mode or the other which for those with storage heaters means they are either on all the time, or off all the time.
None of these situations could be described as 'working correctly'.
 
We have talked about this a few times Energy bill hikes to hit hundreds of thousands and What is a suitable meter and neither thread really came up with firm answers.

One has to question why information is not easy to find, we have known this problem was coming for years. I think people in charge thought by now there would be very few teleswitches left, and all who needed split tariffs would have already moved to smart meters, however rather than aim adverts at those with Economy 7 it was aimed at the gullible, with a Freddie Boswell look alike trying to get every Tom, Dick and Harry, to fit smart meters, rather than concentrate on those who need smart meters.

I found I needed a smart meter to get paid for export, and having an off-peak would also help. 7th September 2023 I started trying to get a smart meter fitted, 30th January 2024, and 4th April 2025 before I got split tariff, but 1st May 2025 before I started to get paid for export. I must say British Gas dragged the heals, and Octopus were very quick once I moved to them.

In my case, yes I was loosing money while trying to get it sorted, but I did not lose power. I have exported 4491.7 kWh and around 3000 kWh I got no payment so around £470 lost it seems because I have not been allocated number for the export to be registered.

But that is annoying, to lose supply is clearly a lot worse.

Specifically it would seem the biggest concern is that if a system gets stuck in "day" mode then people may lose heating until a new method of switching is fitted.
 
The point is, by this stage, we should know what is going to happen, not be guessing.
It's very probable that the insiders know more than we do, both about what the standard says, and about how devices actually behave in the real world.

But the insiders are also subject to politics, that can sometimes mean pretending things are better (to avoid looking bad to higher ups) or worse (to persuade people to get on with the upgrade) than they actually are.

It does look like there is some backpeddling going on though. I found the following online

Previously, 30 June was meant to be the deadline for a total switch off. However, since a lot of meters still need to be replaced, the shutdown will happen in stages. We’re still waiting to find out exactly what this will look like, but we’ll provide an update as soon as we can.

Fundamentally, what do you do with a customer who is not cooperating with a technical upgrade but is otherwise in good standing. Breaking in to their house to fix the issue (as is ultimately done for non-payers) seems disproportionate. Especially as I suspect the suppliers don't even know which customers are making use of the switched output. Sometimes you just have to let people feel the consequences of their actions and then try and deal with the fallout as quickly as possible.
 
I did not want a smart meter myself, until I got solar, at which point the smart meter can save/make me money. It took over a year to sort out, and I was losing money as a result, but I had refused a Smart meter in the past, so a lot of it my fault for not getting it installed earlier, but the adverts talk about daft things like gardening at night, instead of talking about the real benefits.

If someone with RTS has refused a smart meter in the past, then they can hardly blame the supplier.
 
AFAIK it will freeze in day or night mode, depending on when the signal is switched off. I'm in the same position, so I moved to a tariff (Octopus) with same rate per kWh day and night. Then it clearly doesn't matter which mode it freezes in (usage in the other mode zero).
There was some scaremongering about things not working correctly after switchoff, to push people into going for a smart meter.
Wrong. It will have a default switching schedule that it runs. See my post #12.

But Smart Meters are the solution for RTS units faulting/failing and losing correct time which may mean they default to the worst possible rate/not switch at all.

RTS currently will / should be switching the heating off peak circuits on/off in your home if you haven't changed the RTS meter to A N Other meter type.
If it stops switching you will have no heating live without an electrician by-passing something to connect up the two separate sets of circuits in your home. Regardless of electric tariff.

{A picture of your metering bits will confirm if RTS switching kit is still there.}

I can see there's a potential problem with storage heaters. I don't have them, but I assume they have an RTS downstream of the kWh meter, unlike mine. The smart meter pushers were trying to imply any type of heating would be affected. All a CH/HW system needs is power, round the clock.

So you don't and have never had RTS control of your electricity supply!
Most will have two meters as shown in this energy saving trust link https://energysavingtrust.org.uk/wp-content/uploads/2025/04/rts-meter-example.jpg.webp

I assume when the signal is switched off the RTS will go into either day or night mode and stay there. But as I'm paying the same per kWh it doesn't matter if it changes over at some odd times.
 
I did a Google for storage heater wiring, and it seems there are many versions, wired in different ways. Some do have both peak and off-peak supplies, but the peak supply may be just for a fan, or it could have special boost elements, some have built in time clocks, others don't, so unlike the days of the original "White" meter, one needs to look at each storage heating system independent to rest, as there are so many variations.

1750166797600.jpeg This is the problem, there is no one fits all, here clearly one meter, and not all old set-ups used1750167041343.jpegRTS, there are still a few around it seems with simple timers.

The same problem with Smart meters, we have a whole array of systems, some the Smart meter has two outputs peak and off-peak, some it is down to the user to ensure his equipment turns on at the right time.

Here was are responding to @DiyNutJob we are not really worried about any other systems, only his. He asks "Does the RTS turn off at the end of June affect lights and sockets?" simple answer not it does not. @Mottie made non-useful comments, but @Taylortwocities in #3 gave the answer. Plus extra advice and a request for pictures to confirm.

I rambled on, maybe I should not have? And @DiyNutJob posted pictures of his meter. @Taylortwocities again very good post referring to the bill, and asked for more pictures.

@Rodders53 came in with some good background information, and @Harry Bloomfield repeated @Taylortwocities for more pictures and also like @Taylortwocities referred to the bill.

@endecotp pointed out one could be over paying if times are wrong, and @aveatry referred to repeated adverts and letters, and @fixitflav and @Harry Bloomfield talked about rumours as to what may happen. @flameport then explained, as only he can, what is inside the units, and pointed out it is a very real problem, and I pointed out there were threads where this had been talked about in more general terms.

But we have not seen a picture of the consumer unit/s, however it does seem as far as @DiyNutJob is concerned unlikely to lose power, the only question is will he be overcharged. No real answer can be given until we get more information, it will be interesting to see what the suppliers do if someone is overcharged due to them not changing the meter on time, but I would think nothing, when I look at my bills.
 
I thought my comment was useful for this poster as it wouldn’t surprise many on this forum if he said he was going to replace it himself with a 'China' meter from Temu!
OK point taken. But I had assumed it was just poor English, and he meant I have not had my meter changed yet, I did not think anyone thought they could fit their own meter for import, however export meters were fitted by solar panel installers until a few years ago, so yes he could have thought it was down to him.

Only needed a one word answer, "No".
 
Oops my bad for not reading whole thread accurately, rather skimming it.

BUT that meter pic is badly out of focus... and doesn't show enough of where the tails come from and go to (DNO cutout, consumer fuseboards etc.,.) imho...

Landis & Gyr two register meter... model type C12/2d? CI 2/2d? or something. Google finds nowt for me.
Bound to be well out of calibration and therefore overdue for replacement. (No date label(s) showing though; have they fallen off / been removed?)

Replace asap and all possible problems wrt RTS will go away.
