As of 30th June 2025, the Radio Teleswitch Service (RTS) will be permanently switched off. For those unfamiliar, RTS is the system used by older electricity meters, particularly in properties on Economy 7 or Economy 10 tariffs. If you’re a landlord or agent, this isn’t just another date on the calendar – it’s a deadline you need to act on to protect your properties and tenants from unnecessary disruptions.
Let’s break down what this means and how you can take action without the hassle.
What’s an RTS Meter, and Why Should You Care?
Introduced in the 1980s, RTS meters rely on a radio signal to manage off-peak electricity tariffs. These meters have been commonly used in homes with electric storage heaters or water heating systems, where off-peak tariffs provide cost savings for energy consumption during quieter times of the day.
Here’s the problem: after June 2025, the radio signal that makes RTS meters work will be switched off. This means affected meters will no longer function as intended. The risks? Higher energy bills for your tenants, potential disruption to heating and hot water, and the possibility of non-compliance with legal obligations to provide essential utilities.

How Many Homes Are Affected?
Across the UK, it’s estimated that 600,000 RTS meters are still in use, and a significant proportion of these are in the private rental sector (PRS). With 19% of UK households in the PRS (around 4.6 million homes) this issue isn’t small-scale and could affect up to 114,000 rented properties.
As a landlord or agent, you’re likely to have at least one property in your portfolio that could be impacted.
How to Check if a Property Has an RTS Meter
If you’re unsure whether one of your properties has an RTS meter, here’s what you (or your tenants) can do:
- Check the Serial Number: RTS meters often have serial numbers beginning with specific codes, such as “RTS” or others tied to Economy 7/10 tariffs.
- Inspect the Meter: Older meters with a radio-controlled switching system are strong candidates for RTS classification.
- Ask the Energy Supplier: Energy companies can confirm whether the meter at your property is affected by the upcoming switch-off.
Agents and landlords should ensure this information is shared with tenants as part of regular communications. Empowering tenants to identify these meters is a proactive step toward resolving the issue in time.
What Are the Options?
Once you’ve confirmed an RTS meter is in use, the next step is to explore replacement options. While many energy suppliers will recommend upgrading to a smart meter, this isn’t your only choice. Speak with the energy supplier to discuss alternatives and make the decision that best suits your property and tenant needs.
The key here is timing: replacing an RTS meter isn’t something to leave until the last minute. Acting early ensures your tenants avoid unnecessary disruptions and higher costs.
How Inventory Providers Can Help
Here’s where inventory providers come in. A good inventory clerk doesn’t just document the condition of your property – they’re your eyes and ears on the ground. By incorporating RTS meter checks into routine inspections, inventory providers can help you stay ahead of the deadline.
What Inventory Providers Can Do:
Identify and Record RTS Meters
- Inventory clerks can check the type and serial number of meters during inspections.
- Photographs and clear documentation of the meter can be included in reports.
Provide Clear Recommendations
- If an RTS meter is identified, inventory reports can flag the issue and suggest next steps, such as contacting the energy supplier to discuss replacement options.
Streamline Communication
- Inventory reports provide a detailed record for agents, landlords, and tenants, ensuring everyone is on the same page about the necessary actions.
By leveraging the expertise of inventory providers, you can avoid surprises and ensure your properties are compliant well before the RTS signal is switched off.
The Role of Property Inspections
Regular property inspections are your best tool for managing changes like this. By integrating RTS meter checks into your inspections, you can:
- Proactively Identify Issues: Spot outdated meters early and plan for their replacement.
- Ensure Compliance: Stay ahead of legal obligations to provide uninterrupted heating and hot water.
- Avoid Costly Delays: Last-minute replacements can be expensive and disruptive – early action is always more efficient.
Including meter checks as part of routine inspections is a simple yet effective way to prepare for the change while demonstrating diligence to tenants.
Don’t Wait Until It’s Too Late
The RTS meter switch-off is coming, and while June 2025 might seem far away, the clock is ticking. Whether you’re a landlord, agent, or tenant, taking action now ensures you avoid unnecessary stress, costs, and disruption.
For landlords and agents, consider partnering with inventory providers who can incorporate meter checks into their reports. For tenants, take a moment to check your meter and speak with your landlord or energy supplier if you think your home might be affected.
By working together, we can ensure a smooth transition and keep the lights (and heat) on for everyone.
