⚡ We are the leading platform about home batteries of the United Kingdom
HomeBattery.co.uk is the UK’s go-to platform for everything you need to know about home batteries and residential energy storage. As electricity prices remain unpredictable and the interest in solar energy increases, more UK households are exploring ways to take control of their energy use. A home battery gives you the ability to store electricity and use it when it suits you best, helping you reduce energy bills, rely less on the grid, and make the most of your renewable energy system.
A home battery, also known as a solar battery or energy storage system, is a device that stores electricity for later use. It can store excess power generated by solar panels during the day, or charge using cheaper electricity during off-peak hours. The stored energy can then be used in the evening, during peak pricing periods, or in case of a power cut. By shifting your energy consumption to more affordable or sustainable times, a home battery makes your energy use smarter, cleaner, and more efficient.
In the UK, interest in home batteries is rising as people look for ways to stabilise energy costs and improve energy resilience. With the right setup, a home battery can significantly lower your electricity bills and help you make better use of solar panels or time-of-use tariffs. Households are also becoming more conscious of their carbon footprint and want solutions that support a more sustainable lifestyle. In addition, battery storage can provide peace of mind in case of grid outages, offering backup power to keep essential appliances running.

There are generally two types of batteries available for residential use: fixed home batteries and plug-in or portable models. Fixed batteries are permanently installed, often mounted on a wall or placed on the floor, and typically offer higher capacity and deeper integration with solar panel systems. Plug-in batteries, sometimes called plug-and-play home batteries, are easy to install without an electrician, making them a popular choice for renters or those looking for a more flexible solution. Both options have their pros and cons depending on your energy usage, space, and budget.
Battery capacity is measured in kilowatt-hours (kWh) and determines how much energy a battery can store. For example, a 5 kWh battery can theoretically power five 1,000-watt appliances for one hour. The average UK home uses between 6 and 12 kWh per day, though this varies depending on household size and lifestyle. Smaller batteries can cover basic evening usage, while larger ones offer extended backup during outages or cloudy days. Choosing the right capacity depends on your daily energy usage, solar production (if any), and how much of your energy use you want to shift or store.
The cost of a home battery system in the UK depends on several factors, including storage capacity, technology, brand, and whether professional installation is needed. Plug-in batteries generally start from around £1,500, while fixed systems range from £3,000 to £8,000 or more. Prices can vary based on whether the battery is bought alone or combined with a solar panel system. While the upfront cost can seem significant, many users find that the long-term energy savings and increased self-sufficiency offer a strong return on investment, especially when paired with smart energy tariffs.
| Battery Capacity | Average Price (excl. VAT, incl. installation) |
| 5 kWh home battery system | £1850 |
| 10 kWh home battery system | £3800 |
| 15 kWh home battery system | £7500 |
| 20 kWh home battery system | £9000 |
The prices of home battery systems in the UK are constantly changing. In 2025, you can expect to pay between £1,850 and £9,000 for a complete system, including installation but excluding VAT.
The total cost depends on several factors, such as battery capacity, brand, and features like backup functionality or smart charging options. Below is an overview of the average price per battery size, giving you a clear idea of what to expect when considering a home energy storage system. We regularly update this information so you always have access to the latest UK home battery prices.
A home battery may be the right choice if you want to reduce your electricity bills, increase your use of renewable energy, or prepare your home for power interruptions. Even if you don’t have solar panels, you can benefit from charging the battery at night when electricity is cheaper, and using it during the day when prices are higher. If you already have solar panels, adding a battery can help you use more of the electricity you generate yourself, rather than exporting it to the grid. Battery systems are also becoming smarter, with apps and software that allow you to monitor, optimise and automate your energy usage.
