Without the technology to tell RTS meters when to switch between peak and off-peak rates, they may no longer work properly, and it could mean that a consumer’s heating and hot water supply stops functioning as normal.
If you have an RTS meter, your electricity supplier will get in touch to arrange an upgrade to a smart meter before this deadline.
They must make sure you have a suitable meter installed, and that your service is not disrupted.
Ofgem expects electricity suppliers to replace all RTS meters before the technology supporting RTS ends in June 2025.
Support to upgrade RTS electricity meters
Ofgem is working with energy suppliers, distribution network operators, consumer groups and others as part of the RTS Taskforce to support people with an RTS electricity meter.
If you have an RTS electricity meter your electricity supplier will contact you to arrange an appointment to upgrade your electricity meter. You should arrange an upgrade of your meter to avoid losing heating or hot water after June 30th, 2025.
Find out if you have an RTS meter
You may have an RTS meter if:
- it switches between peak and off-peak tariff rates
- it automatically turns on your heating or hot water
- your home is heated using electric or storage heaters
- there is no gas supply to your area, including households in rural areas and high-rise flats
Get in touch with your electricity supplier if you’re still not sure which meter is in your home.
If you have an RTS meter in your home, view details on your electricity supplier's website to upgrade your meter.
If you live in England or Wales, you can contact Citizens Advice for free and impartial advice about your energy supply.
If you live in Scotland, you can get advice and information on energyadvice.scot.
