Originating in the nineteen eighties, the RTS employs a longwave radio transmission. This transmission permits energy providers to alternate measuring devices between higher and lower cost electricity pricing periods. The system mainly helps dwellings that depend on electrical power for warmth and providing hot water. This frequently means properties have electric storage heating units or water tank immersion elements that accumulate energy during nighttime hours, when power costs are usually reduced. This particular method is now outdated. The apparatus generating the radio transmission is at the conclusion of its functional lifespan; sufficient upkeep is impossible. Therefore, this utility will stop functioning.

The Scale of the Challenge

Around late April 2025, reports indicated that approximately 430,000 residences in the UK still utilized RTS measuring devices. Within Scotland, this number was close to 134,000. The trade body for the energy sector, Energy UK, indicated that providers exchange more than one thousand RTS measuring devices each day. This speed, however, does not meet the necessary rate to modernise all implicated meters before the target. Campaigners express anxiety that upwards of three hundred thousand dwellings could experience service interruptions if upgrade activities do not quicken substantially. The initial cut-off was March 2024. Authorities, however, pushed this back to provide additional time for the intricate replacement initiative.

Potential Consequences for Households

The RTS deactivation creates significant dangers for impacted residences. Individuals might experience an absence of warmth or hot water supply. Conversely, their heating apparatus could remain perpetually active, possibly causing extremely large energy expenses. The energy market supervisor, Ofgem, additionally pointed to dangers such as electric storage heaters activating during more costly peak daytime periods. This action could negate the financial advantages of off-peak electricity rates. Providers might also encounter difficulties in accurately verifying electricity consumption for peak or off-peak intervals, potentially leading to inaccuracies in billing.

Industry and Regulatory Response

Ofgem diligently oversees developments, mandating that providers deliver progress reports every two weeks. The regulator formed an RTS Taskforce. This group unites energy suppliers, operators of distribution networks, consumer advocacy bodies, and various other interested parties. This taskforce strives to synchronize actions, disseminate information, and quicken the replacement activity. Energy UK affirms that suppliers are exerting maximum effort to replace the outstanding meters. The focus includes creating backup plans for individuals whose measuring devices might not be exchanged before the cut-off, especially vulnerable people.

The "No Detriment" Commitment

A primary apprehension for consumers moving away from RTS measuring devices relates to the possibility of higher energy expenses. Advocacy organizations have requested clear information and solid assurances concerning Ofgem's "no detriment" pledge. This guiding idea aims to make certain that consumers transitioning from an RTS measuring device to a modern smart meter configuration avoid increased costs for their power directly due to the alteration. Upholding this pledge is essential for preserving consumer confidence. It also helps lessen financial strain, particularly for those with limited finances or distinct heating requirements linked to off-peak electricity rates.

What if Consumers Decline a Smart Meter?

Although smart measuring devices are the usual substitute, certain individuals might choose not to accept one. This choice, nonetheless, can lead to repercussions. Providers could shift people who reject a smart device away from variable-rate pricing structures like Economy 7. This might mean a single, possibly more expensive, charge for all electricity consumed. Manual meter checks could then become a requirement. In some situations, especially with older properties in rural areas, universally compatible smart metering options may not yet be available. This would require suppliers to identify appropriate temporary measures. Discussing specific situations with their supplier is crucial for consumers.

Supplier-Specific Challenges and Progress

Distinct energy providers encounter their own particular difficulties within the RTS replacement scheme. For instance, British Gas formerly oversaw approximately 61,000 RTS measuring devices. While it substantially lowered this figure, the company still had to connect with about 12,000 homes as early 2025 approached. Other large-scale suppliers, such as EDF, also indicated many customers required upgrades. Some providers have faced criticism for making slow headway. Ofgem observed in early 2024 that a few major providers had updated under a tenth of their total RTS meter installations. This underscores the differing speeds and complexities of the undertaking among various companies.

The RTS meter exchange presents notable complications in countryside and island localities. These places frequently exhibit a greater density of homes depending on electric heating and RTS measuring devices. Operational difficulties, such as the accessibility of engineers and journey durations, become more significant. Additionally, establishing reliable connections for smart measuring devices can occasionally present difficulties in such areas. However, remedies like the Alt HAN (Alternative Home Area Network) are under development and deployment to tackle these matters. The Scottish Government has voiced considerable unease regarding the consequences for its rural and island populations, pressing suppliers to outline their staffing strategies for servicing these properties.

Phased Shutdown Approach

The RTS transmission will not cease suddenly across the nation simultaneously. Ofgem explained the deactivation will be gradual. This procedure commences after the thirtieth of June 2025, likely advancing district by district until September 2025. Although this staged technique provides some leeway, it does not lessen the need for consumers to take action. Postponing a meter exchange still carries the danger of interruptions to warmth and hot water provision once the transmission stops in their locality. This phased method requires careful coordination to manage effectively.

Communication and Awareness Campaigns

Substantial initiatives are in progress to heighten consciousness regarding the RTS cessation. Ofgem initiated public awareness drives. These include television commercials with figures such as Lorraine Kelly, encouraging individuals to get in touch with their energy providers. The regulator additionally furnishes a resource pack for interested parties, like local government bodies and community organizations, to assist in spreading the information. Energy suppliers have a duty to make contact with all impacted customers. Nevertheless, anxieties persist that some consumers, especially older people or those with less digital engagement, might not receive these messages or might not grasp the full implications.

The Role of Landlords and Housing Associations

For individuals renting their homes or living in properties overseen by housing associations, the RTS meter upgrade procedure might include an extra stage. Property owners or housing bodies may need to authorize the meter switch. Tenants who think they have an RTS measuring device should inform their landlord or housing association. Cooperating with their energy provider to enable the upgrade is also important. Housing associations themselves are vital participants in informing their residents. Certain groups, for example Samphire Homes, pro-actively update their occupants about the forthcoming alterations.

Technical Solutions and Innovation

The power sector persistently develops technical remedies to surmount obstacles in the deployment of smart measuring devices, a vital step for substituting RTS units. A meter equipment manager, SMS plc, has put resources into amenities such as a specialized RTS testing laboratory. This helps suppliers verify smart meter options for intricate setups. They also suggested a unified workforce strategy to address RTS exchanges more effectively, though this concept is not yet fully implemented. Such advancements are crucial for resolving problems in difficult settings, like apartment buildings with undersized meter rooms or regions experiencing poor Home Area Network (HAN) signals.
