Store energy, save money. Home battery systems let you store cheap electricity and use it when prices are high - or keep the lights on during a power cut.
A home battery system stores electricity for use when you need it most. Whether you have solar panels generating free power during the day, or want to charge from the grid during cheap off-peak hours, a battery lets you use that energy whenever suits you.
Modern lithium-ion batteries are compact, safe, and virtually maintenance-free. They can be wall-mounted in a garage, utility room, or even outside, and typically last 10-15 years or more.
Use your solar electricity in the evening instead of exporting it.
Charge at 7p/kWh overnight, use during peak times at 30p/kWh.
Keep essential circuits running during power cuts with backup-enabled systems.
Home batteries integrate seamlessly with your electrical system and can work with or without solar panels.
Excess solar electricity charges the battery instead of being exported to the grid.
On time-of-use tariffs, charge overnight when electricity is cheapest (as low as 7p/kWh).
The battery holds the energy safely until you need it - typically 5-15kWh capacity.
Use stored energy in the evening or during peak rate periods to avoid expensive grid electricity.
Battery storage makes sense in several scenarios - you don't necessarily need solar panels.
Without a battery, you might only use 30-50% of the solar electricity you generate. A battery lets you store daytime solar for evening use, potentially achieving 70-80% self-consumption.
Even without solar, you can save money with tariffs like Octopus Go or Economy 7. Charge the battery at 7p/kWh overnight and use it during peak hours when rates hit 30p/kWh or more.
If you work from home, have medical equipment, or simply want peace of mind, a battery with backup functionality keeps essential circuits running during power cuts.
Here's how a battery can pay for itself, even without solar panels:
Using a time-of-use tariff, charge a 10kWh battery overnight = 70p
Discharge during peak times instead of buying from grid = £3.00 saved
That's over £800 per year, just from smart charging - more with solar!
* Actual savings depend on your usage patterns, tariff, and battery size. We'll calculate your potential savings during the survey.
Home battery prices vary by capacity and brand. A typical 5kWh system costs around £3,000-£4,500 installed, while larger 10-15kWh systems range from £5,000-£10,000. We install leading brands including GivEnergy, Tesla Powerwall, and Sunsynk.
No! While batteries work brilliantly with solar panels, they also make financial sense on their own if you're on a time-of-use electricity tariff. You can charge overnight at cheap rates and use the stored energy during expensive peak periods.
Modern lithium-ion batteries typically have a warranty of 10-12 years and are rated for thousands of charge cycles. Most will retain 70-80% of their original capacity after 10 years, and many continue working well beyond their warranty period.
Yes, modern home batteries use lithium iron phosphate (LFP) chemistry which is extremely stable and safe. They're designed to be installed indoors or outdoors and include multiple safety systems. All our installations comply with current regulations and are MCS certified.
This depends on your electricity usage and whether you have solar. A typical household uses 8-10kWh per day, so a 5-10kWh battery covers evening usage. With solar panels, you might want a larger capacity to store more daytime generation. We'll recommend the right size during your survey.
