Frequently Asked
Questions
Everything you need to know about battery storage systems and how they can work without solar panels.
Can a battery save money without solar panels?
Yes. Home batteries can charge using cheaper off-peak electricity from the grid and power your home when electricity prices are higher during the day. This allows many UK homeowners to reduce electricity costs without investing in solar panels. If you decide to add solar in the future, most battery systems can support it too.
What is home battery storage?
Home battery storage allows you to store electricity for use later in the day when you need it most.
A battery can store energy from the grid during cheaper tariff periods or from solar panels if you have them installed. The stored energy can then be used to power your home during peak-rate periods, helping to lower bills and increase energy independence.
How much does a home battery system cost?
The cost of a home battery system depends on the battery size, inverter type and installation requirements.
Typical systems for UK homes generally start from around £3,000–£5,000 installed, with larger systems for higher energy usage or EV charging costing more.
Our team can help recommend the right system based on your home and energy usage.
Are home batteries worth it in the UK?
For many UK households, yes.
Home batteries are particularly valuable for homeowners on time-of-use tariffs, households with higher evening electricity usage, or anyone looking to reduce exposure to rising energy prices.
With electricity costs remaining volatile, a battery can provide greater control over your energy usage while helping reduce monthly bills.
What size battery do I need?
The right battery size depends on your household electricity usage, heating type and whether you have an EV. Most UK homes are well suited to battery systems between 5kWh and 15kWh. If you're unsure, our team can help recommend a suitable size based on your typical energy usage.
Can I add solar panels later?
Yes. Many homeowners install battery storage first to take advantage of off-peak electricity tariffs and add solar panels at a later date. Most modern hybrid battery systems are designed with future solar integration in mind.
How long do battery systems last?
Most home battery systems are designed to last 10 to 15 years, with many continuing to operate beyond this period. Battery lifespan depends on usage patterns, operating conditions and the specific product selected.
What happens during a power cut?
Standard battery installations switch off during a power outage for safety reasons. However, some systems can be configured with backup or emergency power functionality, allowing selected household circuits to continue operating during a power cut.
What are time-of-use tariffs?
Time-of-use tariffs charge different electricity prices at different times of the day. Electricity is often cheaper overnight and more expensive during peak evening hours. Home battery systems can store cheaper electricity and use it later when prices are higher.
Does it work with off-peak tariffs?
Yes. Battery storage works particularly well with off-peak tariffs by charging when electricity prices are low and supplying power back to your home during more expensive periods. This can help reduce electricity costs without requiring solar panels.
Is it suitable for UK homes?
Yes. Home battery systems are suitable for the vast majority of UK homes, including detached, semi-detached, terraced houses and many flats. Systems are available in a range of sizes to suit different energy usage patterns and available installation space.
What is included in the kit?
Our battery storage kits typically include the battery, inverter, essential mounting hardware and required communication components for the system to operate. The exact contents may vary depending on the package selected and installation requirements.
Is installation required by an electrician?
Yes. Battery storage systems must be installed by a qualified electrician or certified installer to ensure the system is installed safely and complies with UK regulations and electrical standards.
Can businesses use battery storage?
Yes. Battery storage can help businesses reduce electricity costs by storing cheaper off-peak energy for use during peak periods. Systems can be sized to suit a range of commercial applications, from small offices and retail units to larger commercial premises.
