UK consumers are preparing for a surge in energy bills, projected to approach £2,000 annually under the new government price cap. In response, many are exploring green home upgrades, particularly home batteries, which have seen prices plummet by 90% since 2010. These batteries can help households cut costs and manage energy use more effectively. For instance, homes with electric heat pumps or car chargers stand to benefit significantly, with potential savings of up to 87% on electricity bills. A typical household in Milton Keynes could save nearly £760 annually by utilizing a 5kWh battery alongside solar panels. The payback period for such investments can range from nine to 13 years, depending on energy usage and solar power generation. Innovations on the horizon, such as plug-in batteries and vehicle-to-home charging, promise to further enhance energy savings for households. With proper installation and management, home batteries are considered safe and can be a gamechanger in the fight against rising energy costs.
