Radio teleswitch (RTS) shutdown sunset FAQ

Updated on 14/06/24 by Shads_OVO

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.

As you may know, some big changes are coming which affect old electric meters that use Radio Teleswitches. Here’s some helpful FAQs about what’s happening.

What is the Radio Teleswitch System?

The Radio Teleswitch System (or RTS for short) is a system that was created to help with the control and management of electricity meters that had special tariffs such as Economy 7 prior to the existence of smart meters. It has a few features that are seen in smart meters today, such as remotely switching between Day or Night rates and automatically turning heating/hot water on or off, but doesn’t have the ability to collect meter readings.

As a fun fact: The same signals and frequencies also get used for the BBC Radio 4 longwave service, and the three transmitters have enough power to blast the signals across the entire country at once.

What is a Radio Teleswitch Meter?

These are legacy meter types that may be known as Radio Teleswitch Meters (RTS Meter) or Dynamically Teleswitched Meter (DTS Meter), however they both work in a similar way. Alongside the electricity meter itself, a Radio Teleswitch device would also be installed and it’s this device which picks up the RTS signals and controls the time switching features on the meter.

So are they smart meters?

Well… Sort of… But not quite. The signal was only ever one-way and had no way for meters to send any kind of replies, while current smart meters can do two-way links. But you could say that they were a really early form of smart meter! :wink:

Many RTS Meters could be updated with a single message, such as making changes to every time switch in a particular area all in one go. Smart Meters can only be updated individually and will ignore random broadcasts that don’t specifically target the meter directly, making them more secure.

What are DTS/RTS Meters used for and why would I have one?

These meters were mainly used for special tariffs such as Economy 7/Economy 10, HeatWise, WarmWise, Total Heat Total Control and Weathercall. Officially speaking, the tag line for them was “Using Radio transmissions to control tariffs and loads economically and reliably.” The purpose was to allow entire groups of meters to be switched in one go based on the appropriate tariffs. It also had the ability to be used for certain emergency scenarios as well. They were not used for single-rate tariffs.

What kind of tariffs were these meters installed for?

OVO has never offered or supported any legacy RTS/DTS Tariffs, but other suppliers have done so in the past. A full list is hard to locate, but here’s a few examples of known tariffs:

Economy 7 (only if it’s a load controlled plan where an RTS Meter is installed)
Economy 10 (only if it’s a load controlled plan where an RTS Meter is installed)
Total Heat Total Control
Weathercall
HeatWise
WarmWise
Storage Heat Control
White Meter
Superdeal
Flexiheat
Comfort Plus
Comfort Plus Control
Twin Heat

These tariffs sound like good deals, so why doesn’t OVO offer them?

Well… Here’s the thing… They’re all legacy tariffs and RTS/DTS Meters are all legacy meter types which are no longer installed. On top of that, the RTS service is actually shutting down by the end of December 2023 and this would make it impossible to provide such tariffs without smart meters being used. Most of them are also not exactly great value for money either…

It’s also worth noting that almost all such tariffs are closed to new customers (except the standard non-teleswitched Economy 7 which is definitely not going away!) and the suppliers which previously installed RTS/DTS Meters are ending support for them soon anyway.

These meters are also on life support at this point, since the BBC has been trying to shutdown the BBC Radio 4 Longwave service since 2014!

I’ve got an RTS/DTS Meter at the moment and it’s working fine. So what’s the problem?

All of these meters are legacy types which are no longer installed by any supplier today. The shutdown of the RTS service would mean that the teleswitching features would completely stop working, which could in theory leave your electricity meter jammed on the last rate it was on before the signal died, prevent your heating/hot water from turning on properly or leave the heating/hot water jammed on 24/7. OVO’s Resident Smart Meter Expert (and that’s not me!) is working with the industry and Government to figure out a safe migration plan and keep the RTS Service running until all customers can be migrated off it. The signal will be turned off eventually, but only after alternative solutions have been implemented to ensure that your heating and hot water continue to work properly.

In addition, many of these legacy meters are reaching end of life and the certifications are about to expire due to age. When this happens, suppliers are required to replace the meter as part of the terms of their licenses. There are still stocks of RTS Meters in the inventory that OVO and other suppliers have access to - but these stocks are reserved for existing installs only and will not be used for new installs. These stocks are intended to be used to help with maintenance of existing setups, such as replacing faulty RTS Meters.

But I don’t want a smart meter and I’ve already made it clear that I wanted to opt-out! Can I have a non-smart meter instead? And why is my supplier not respecting my request?

Due to the rules that suppliers have to follow, suppliers are only allowed to “override and bypass” a smart meter refusal in specific circumstances. They cannot bypass just because they want to try and meet targets or boost their stats. However, attempting to force an upgrade due to a meter fault, for safety reasons, end of life meters, expired certifications or for accuracy reasons are considered valid cases to bypass opt-outs.

OVO has stated however, that they will not force a Smart Meter upgrade on a member who doesn’t want one. I’ve had confirmation that OVO is working with both the Citizens Advice Bureau and the Energy Ombudsman to help with discussing any concerns with members who decline an upgrade to see if there’s anything that can be done to resolve such concerns. They’re willing to discuss these with you for as long as you wish and you won’t be forced to make any decisions if you’re not ready.

I’m no longer with the supplier that originally gave me the meter and I don’t have that kind of tariff anymore. What can I do?

The good news is that your current supplier will be happy to sort you out and they’ll be in touch at some point. Parts of OVO Group did offer legacy tariffs or meters that relied on RTS/DTS, other suppliers did so back in the day. All suppliers have a duty of care to help customers migrate over to smart meters, and this includes OVO. Your current supplier will know if you’re affected and they’ll be best placed to assist.

What will happen if I don’t get my meter replaced/upgraded?

Impending doom is sure to follow and there’ll be no way to escape your fate! And you really don’t want to be trapped in a temple of doom with a 500 stone boulder chasing after you…

What will actually happen is that your meter will stop working properly and it may mess up your bills pretty badly. If your heating and hot water are also controlled via RTS, it’s very likely that your house will turn into The North Pole or Sahara Desert… Not sure which one I’d prefer myself to be honest…

OVO have advised that they’re working incredibly hard to make sure the RTS closure is only done when all customers impacted can get a suitable solution. So this is worst case scenario if nothing was done and OVO were negligent.. something they have no plans to be.

Hold up! I’ve got Economy 7 and I’m with OVO?! What do I do?

Firstly, please don’t panic, OVO has considered this possibility. Economy 7 tariffs are fully supported by all suppliers which provide them, including OVO and there’s no plans to change that. If you’ve got a smart meter in Economy 7 mode, you’re good to go and the RTS shutdown won’t affect you.

However, if you are on Economy 7 or Economy 10 with any supplier and don’t have a smart meter, now might be a good time to consider getting a meter upgrade.

I’ve got one of these legacy meters, but I moved to a single-rate tariff. Does this still affect me?

Kind of. The good news is that it won’t hit you as hard, but you would still be affected to a degree. I’d recommend upgrading to a smart meter anyway to make sure your current meter doesn’t come back to haunt you later. Given that the meter is probably reaching end of life anyway and the certification is probably going to expire soon, my advice would be to say that you are affected.

As a bonus, replacing your meter might even let you get rid of that second MPAN (Meter Point Administration Number) if your RTS setup currently has one.

What will happen to my tariff?

Good question! Your tariff will be set free into the wild where it can relax and enjoy the luxury of retirement, safely looked after by the best hospitality in the jungle… Meanwhile, a Dungeoneer will cast some magic that summons a much younger and more modern tariff to take its place, just for you.

Spellcasting! R E F R E S H

Or I wish I could say that! The exact answer will depend on your circumstances - OVO have advised that this totally depends on the RTS arrangement in place and where in the UK you may be... I hear there are challenges being faced with replacing RTS meters that are being worked upon. So I strongly recommend talking to your supplier about your options, or consider switching to a new supplier - you can sometimes get better deals by switching anyway.

Just a heads up though. Once you switch away from a legacy tariff, you won’t be able to get it back. Please make sure to choose your options carefully. Or as Treguard used to say…

The only way is onwards… There is no turning back.

I’ve got another question that’s not covered? I’m still confused and need more help! Where can I go?

Right here! These forums are the perfect place for getting help and advice like this, and we’d be more than happy to help you out. Feel free to create a new topic on the forums or reply to an existing one that’s similar and we’ll swoop into action.

It might be that both are moving, but one got there first. I don’t work for OVO and can’t access the accounts though.

Thread Bump.

Any further news on PolyPhase Smart meter availability for domestic two phase dwellings ?

Already exists :)

OVO is rolling it out right now, but availability is HEAVILY dependent on trained engineers being in your area.

OK, is there a special route to enquire, or a magic ‘trigger word’ without having to go through the rigmarole of trying to explain yet again the complex conditions?

My mother is still with SSE, not been migrated to OVO yet, might it be easier to wait for that to happen first ?

Nope, standard routes apply. Just go to https://smart-booking.ovoenergy.com and apply as normal. OVO’s teams will notice it’s a Polyphase setup and rebook it in the background.

Your mother will need to wait to be moved to OVO first. The SSE brand is going away at the end of October, so it won’t be much longer.

Ok, thanks @Blastoise186 . I really didn’t want this done in the winter, because for obvious reasons, no one will know whether the install is working properly until the next morning ! Unless the installers have some means to trigger the switching ad-hoc ?

There are a LOT of checks and balances. If the upgrade is impossible, it gets cancelled without being done. If commissioning doesn’t finish, the meter just runs like a normal one with all circuits live 24/7.

OK, thanks again . Anyway, I’ll make damn sure I’m there the day it happens !

I’ll get on the case the moment she is migrated to OVO.

np. If needed, the ECAUL and ALCS configs can be remotely pushed via SMETS Command as well without the need for a second engineer visit. Fixes almost all time switching issues within an hour.

I’ve lived in the same house for almost two years, and have recently found out I have both a single watt meter and a radio teleswitch meter in the house. I’ve submitted readings from the single-watt meter regularly since moving in and never bothered with the teleswitch, as my housing association never told me otherwise. I’m now contacting my supplier (Octopus) to register for a smart meter but I’m scared that I should’ve been submitting readings for the teleswitch as well this whole time and that I’m now in lots of debt. Can anyone shed light on the situation? I’ve attached images of both meters. The teleswitch says ‘no load’ which I’m not sure means anything.

I think you need to discuss that with Octopus I’m afraid - this heavily depends on their policies.

No Load is exactly what it says on the tin - the meter isn’t seeing anything going through it.

Noted, I’ve contacted Octopus about this and am waiting on a response, so I thought I’d try and get some advice while I wait. Do you think it’s possible for me to be in debt/trouble as a result of this meter? I really don’t understand it, apologies if it’s a silly question

I don’t think so. I suspect the worst is that you’ve got a ton of estimated reads that will have contributed towards paying something off. You might even end up with a massive refund!

With that being said, Octopus is not really equipped to deal with whatever tariff configuration your meters were supposed to be used with...

Duly noted, thank you! There’s also a possibility that the radio teleswitch isn’t doing much at all, as when I first moved in there was lots of confusion regarding what kind of meter I had and Bulb (my then provider,) ended up saying I owed them £7,000! obviously they realised they’d mucked up (they’d charged me for the previous tenants energy,) but it’s possible that before I moved in the previous tenant switched meters and didn’t remove the teleswitch, which maybe contributed to the muck up. It’s all speculation though, I’ll wait for Octopus to respond and keep an eye on it. Thank you for the help!

No worries. :)

Unfortunately, only a handful of suppliers actually know the full ins and outs of the meter setup that I think you’ve got and Octopus isn’t one of them.

Hey @bbriii,

If they are charging for that meter, it would be based on estimates if no actual reading are submitted. If it says ‘no load’ I assume that no energy is passing through that meter.

Your energy supplier will be able to advise further, it may be that the meter is no longer in use and can be removed, so that you’re no longer charged standing charge.

Keep us posted with how you get on.

@bbriii did you get a response from Octopus?

Hi, I got in contact with them and they didn’t seem to have any concerns or issues around the teleswitch, they helped remove a meter from my account that didn’t actually exist at the property and are now processing some credit refunds and meter readings for me, so everything seems good! I reminded them that I may need a smart meter installed before March 2024 as well.

@bbriii I see Octopus are encouraging RTS customers to register for a smart meter

https://octopus.energy/help-and-faqs/articles/radio-teleswitch-service-rts/

Hi, yes; I’ve already registered my interest and am simply waiting for an appointment slot to open in my area, I’ve also gotten permission from my landlord for changing the meters over whenever it is eventually offered to me.

Hi, I have an economy 7 meter in a rural property. I was told I needed to switch to a smart meter because of the RTS shutdown in March 24. The engineer who came to fit the smart meter said there was not a good enough/no signal for a smart meter and told me I needed a heritage meter. What is a heritage meter and how would that differ to what I have already? Would I still get economy 7 with a heritage meter and does it not rely on the RTS?

Thank you!

Hi @APHM ,

Long story short, Heritage Economy 7 Meters would be the ones with local timeswitches that don’t use RTS. They’re sometimes known here as legacy meters.

Heritage Meters are no longer being installed by any supplier known to this forum.

Thank you, that’s helpful.

… there was not a good enough/no signal for a smart meter …

Whereabouts are you? The code from this map will do.

Do you have any neighbours at all, within a mile or two? Do you know whether any of them has a working smart meter? If so, is any of them with OVO (or SSE)?

I ask because there is a way for smart meters to piggyback on nearby properties’ signals, but it does require slightly different hardware at (I think) both ‘master’ and ‘slave’ sites. It’s not certain that the engineer would have considered this approach. Read about this solution here.

Thanks, I’m in area 22 - Cornwall. I will check with neighbours and see if that’s possible. If it isn’t OVO has suggested a ‘dumb’ smart meter but I’m not sure I can get economy 7 with this.
