Use a home battery to store low-cost electricity overnight and power your home during the day.
You don’t need solar panels to benefit from a home battery system.
Modern battery storage systems are designed to work directly with the UK grid. This means you can store cheaper electricity overnight and use it during the day—without generating your own power.
For many homes, this is the simplest way to reduce electricity costs without the upfront investment or installation of solar panels.
At Volt Wiser Energy, everything we offer is built around proven, reliable technology from right here in the UK. We’ve partnered directly with ESME Energy to bring homeowners a smarter, more efficient way to manage their energy use.
As an authorised partner, we work closely with ESME’s team and leadership to ensure every system we promote meets the highest standards of performance, safety, and long-term reliability. Their battery storage solutions are designed specifically for UK homes, with a focus on maximising savings through intelligent energy usage.
All systems are installed by experienced, qualified professionals through ESME’s network, so you can be confident that your setup is handled correctly from day one. This means no shortcuts, no guesswork — just a seamless transition to smarter energy.
By combining UK-engineered technology with expert installation and a transparent, education-first approach, we give you a solution you can trust — not just today, but for years to come.
Yes — in the UK, a home battery system can still deliver strong savings even without solar. Systems from ESME Energy are designed to store cheaper off-peak electricity overnight and use it during the day when energy prices are higher.
This “time-of-use” approach is one of the most effective ways for UK households to reduce electricity bills without installing solar panels.
Savings depend on your energy usage, tariff, and system size, but many UK households can significantly cut their daytime electricity costs by shifting usage to cheaper overnight rates.
With the right setup, a home battery can reduce a substantial portion of your annual electricity spend. ESME systems are built to automate this process, helping you maximise savings by using stored energy at the most expensive times of day.
Most modern home battery systems are designed to last 10–15 years or more, depending on usage and the number of charge cycles.
Systems from ESME Energy are built with long-term performance in mind, using high-quality components and smart energy management to maintain efficiency over time. Many systems also come with warranties for added peace of mind.
To get the best results from a home battery, you’ll typically need a time-of-use tariff such as Economy 7 or smart tariffs like Octopus Go. These tariffs offer cheaper electricity during off-peak hours, allowing your battery to charge at a lower cost and power your home when rates are higher.
While batteries can work on standard tariffs, pairing them with a time-of-use tariff is key to unlocking the full financial benefit.
Some home battery systems can provide backup power during an outage, but this depends on how the system is installed.
With the correct setup, essential circuits in your home can continue running using stored energy.
It’s important to discuss backup options during your consultation, as not all systems include this feature by default, and requirements can vary depending on your property and needs.
