Radio Teleswitch Service (RTS) – what businesses need to know
What is the Radio Teleswitch Service?
The Radio Teleswitch Service (RTS) is a technology used by some older types of electricity meters. These meters often switch between peak and off-peak tariff rates or control heating and hot water. Meters that rely on the RTS have been used reliably since the late 1980s. However, the longwave radio technology it uses will be switched off from 30 June 2025. This change may affect your business. In this article, we explain what’s happening, when it will happen, and how it impacts your business.
Countdown to the end of Radio Teleswitch Service
The Radio Teleswitch Service phase-out was originally planned for March 2024, but Ofgem has confirmed that RTS will be switched off from 30 June 2025. After this date, businesses with meters that rely on RTS may find certain functions no longer work, regardless of your energy supplier.
A lot of meters across the UK need upgrading urgently. Businesses that delay their smart meter install may find themselves in a situation where their energy supplier is unable to offer an appointment before the Radio Teleswitch Service ends. To protect your business from any disruption, we recommend arranging your smart meter upgrade as soon as possible.
Benefits of smart meters
Apart from being the natural next step in meter technology, upgrading to a smart meter comes with a range of benefits for your business. Smart meters work by sending meter readings using technology similar to a mobile phone. That means you won't have to submit your monthly meter readings anymore and you’ll receive accurate bills.
Managing your energy also becomes easier – real-time energy data and past consumption information gives you greater insight and control, and you’ll find your new supplier can connect to your meter quicker with an up to date smart device.
