Millions of UK households could receive free plug-in batteries worth £500 to cut bills.

Millions of UK households, especially those on lower incomes, could be handed free plug-in batteries worth around £500 as part of a proposed new scheme from the Department for Energy Security and Net Zero (DESNZ)1. These innovative gadgets are designed to act as a home power bank, charging when electricity is cheapest and releasing stored energy during peak times to reduce bills. While the prospect of free energy-saving devices is appealing, it is important to understand the current status of this scheme and the practicalities involved.

As the UK explores new ways to manage home energy, Fuse Energy is committed to empowering you with greater control over your usage. We are developing advanced home energy upgrades, including smart battery solutions, to help you manage your power more effectively.

The proposed DESNZ free plug-in battery scheme

What the scheme entails

The DESNZ is exploring a scheme to purchase plug-in batteries in bulk and distribute them to low-income households across the UK. These devices are envisioned as a straightforward way to help families manage their energy costs. The batteries are designed to charge using cheaper, off-peak electricity and then supply power to the home when prices are higher, thereby reducing reliance on the grid during expensive periods. A government source highlighted their appeal, noting they are "so easy to deploy".

Eligibility and potential rollout

Details on specific eligibility criteria for the proposed scheme are still under consideration. However, the focus is clearly on supporting households, particularly those on lower incomes, who are most vulnerable to rising energy costs. Previous Warm Homes Plan grants were typically offered to households earning £35,000 or less, suggesting a similar income threshold could apply to this scheme. The potential rollout timeline remains unconfirmed, as the scheme is still in its exploratory phase.

Current status and timeline

The proposed free plug-in battery scheme is not yet active, and applications are not currently open. It remains a proposal under review by the DESNZ. A DESNZ spokesperson has confirmed that the Energy Secretary's focus is on "working to bring bills down for good" and that VAT on electricity has been cut to provide families with "breathing space".

How plug-in batteries work to reduce energy bills

Plug-in batteries function as personal home power banks, offering a way to optimise electricity usage and reduce overall energy expenditure.

Charging during off-peak hours

These devices are designed to automatically charge during periods when electricity is cheapest, typically overnight or at other off-peak times. This usually aligns with smart electricity tariffs that offer lower rates when demand on the grid is low. By taking advantage of these cheaper rates, households can essentially "stock up" on energy at a lower cost.

Discharging during peak times

Once charged, the battery stores this cheaper electricity. During peak times, when grid electricity prices are higher, the battery automatically discharges, powering your home appliances with the energy it stored earlier. This reduces your reliance on the more expensive grid supply during these periods, directly cutting your electricity bill.

Benefits for household energy savings

The primary benefit is a reduction in household energy bills by shifting consumption away from expensive peak rates. This smart energy management can lead to significant savings over time. Furthermore, these devices can contribute to greater energy independence and security for individual households.

Regulatory and practical considerations

While the concept of plug-in batteries is promising, their widespread deployment in the UK faces certain regulatory and practical hurdles.

UK wiring rules and power feedback

A key challenge is that current UK wiring rules need updating to allow power feedback from these plug-in batteries into homes. This regulatory adjustment is crucial for the devices to operate as intended, seamlessly supplying stored energy back into a home's electrical system. Without these updates, the full potential of plug-in battery technology cannot be realised for domestic use.

Ease of installation and deployment

The proposed devices are designed for easy installation, plugging directly into a standard wall socket without requiring an electrician. This "plug-and-play" design is a significant advantage, making the technology accessible to a wider range of households without the added cost or complexity of professional installation. This ease of deployment is a major factor in the government's interest in the scheme.

Impact on energy security and net zero goals

Deploying plug-in batteries could enhance national energy security by reducing peak demand on the grid and making homes more self-sufficient. By enabling greater use of cheaper, often renewable, off-peak electricity, these devices also support the UK's net zero ambitions by promoting more efficient and sustainable energy consumption patterns.

Potential savings and alternatives for UK households

The financial benefits of using plug-in batteries are substantial, particularly for those who can adapt their energy usage.

Estimated bill reductions

Experts estimate that households shifting their electricity use to off-peak hours could see potential savings of 30-34% off their bills over ten years. This represents a significant long-term financial advantage for participants in such a scheme.

Who stands to benefit most

Households on lower incomes are the primary target for the proposed DESNZ scheme, as they stand to gain the most from reduced energy costs. Renters, who might not be able to install larger home battery systems, could also benefit significantly, with some potentially saving up to £250 annually. The average UK home uses around 2,500 kWh of electricity per year, so even small percentage savings can add up.

Other household energy saving options

While awaiting the rollout of free battery schemes, there are other ways to reduce energy bills. These include ensuring your home is well-insulated, using energy-efficient appliances, and adopting smart thermostats to optimise heating. Exploring smart electricity tariffs that offer cheaper off-peak rates can also help, even without a battery, by encouraging you to run high-consumption appliances like washing machines during cheaper periods.
