Store energy when it's cheap, use it when it counts
A home battery stores electricity so you can use it later—solar energy you've generated during the day, or off-peak grid power charged overnight. You'll rely less on expensive peak-rate electricity and have backup power when you need it.
How a home battery works
Your battery charges when electricity is plentiful and inexpensive—typically from your solar panels during daylight hours, or from the grid during overnight off-peak periods if you're on a time-of-use tariff.
When your household needs power, the battery discharges automatically. You draw from your stored energy instead of buying electricity at peak rates. Any surplus solar generation can still be exported to the grid. The system switches seamlessly, and you stay in control through a monitoring app.
Why add battery storage to your home
Use more of your own solar energy
Without a battery, solar power you don't use immediately is exported to the grid for a low rate. Store it instead and you'll use far more of what your panels produce, cutting the amount you buy from your supplier.
Cut peak-rate electricity costs
Charge your battery overnight on a cheaper tariff and run your home from stored power during expensive peak hours. It works whether you have solar panels or not.
Backup power during outages
If the grid goes down, a battery with backup capability keeps essential circuits running—lights, your fridge, broadband and phone charging—so you're not left in the dark.
Battery storage with or without solar
Solar + battery systems
The most common setup. Your panels generate electricity during the day, the house uses what it needs, and the surplus charges the battery. Once the battery is full, any extra generation is exported. In the evening and overnight, you draw from the battery before buying grid power. You maximise self-sufficiency and minimise bills.
Battery only (no solar)
You can install a battery on its own and charge it from the grid during off-peak hours on a time-of-use tariff. You then use that stored energy during peak times when electricity costs more. It's a straightforward way to lower bills if solar panels aren't suitable for your property.
How we install your battery storage
Survey and design
We visit your property to assess your electrical setup, understand your energy use and discuss whether you want backup capability. We'll recommend a battery size and explain how it will integrate with your existing solar system or standalone.
Quote and timeline
You'll receive a detailed quote covering the battery, inverter (if needed), installation and commissioning. We'll agree on a date that suits you, typically within a few weeks.
Installation day
Our team installs the battery, connects it to your consumer unit and configures the system. Most installations take one day. We test everything and show you how the monitoring app works.
Aftercare and monitoring
You'll have access to real-time data on charging, discharge and savings. We're here if you have questions or need support, and we'll talk you through any tariff changes that could save you more.
Designed around your home and your usage
Every household uses energy differently. We size your battery based on your consumption patterns, whether you have solar panels already, and what you want the system to achieve—maximum self-use, backup power, or both.
Battery capacity and budget
Smaller batteries (5–7 kWh) suit modest evening demand and tighter budgets. Larger units (10–15 kWh) store more solar energy or give you longer backup runtime. We'll show you the trade-offs so you choose the capacity that makes sense.
Backup or grid-tied
Most batteries are grid-tied, meaning they work alongside mains power but don't provide backup during an outage. If backup matters, we can specify a system that islands essential circuits when the grid fails. We'll explain the extra cost and what it covers.
What affects the cost of a home battery
Battery storage pricing depends on capacity, brand, whether you need a new inverter and if you want backup functionality. Retrofitting a battery to an existing solar system may require a compatible hybrid inverter.
Installation complexity also plays a role—the location of your consumer unit, cable runs and any electrical upgrades. We give you a single fixed price that covers the battery, all hardware, labour, commissioning and sign-off. There are no hidden costs, and we'll talk you through any trade-offs before you commit.
