Stop selling cheap and buying expensive. A home battery captures every kilowatt your panels generate and releases it when you need it most — evenings, early mornings, and grid outages.

Typical savings when paired with solar PV.
| Property | Solar size | Battery | Self-sufficiency | Est. annual saving |
|---|---|---|---|---|
| 1–2 bed flat | 3.5 kWp | 5 kWh | Up to 65% | £700 – £900 |
| 3 bed semi | 4.0 kWp | 9.5 kWh | Up to 75% | £900 – £1,100 |
| 4 bed detached | 6.0 kWp | 13.5 kWh | Up to 80% | £1,200 – £1,500 |
| Large home / EV | 8.0 kWp | 19 kWh | Up to 85% | £1,600 – £2,200 |
Figures are estimates based on typical UK consumption and a 26p/kWh import rate (Ofgem price cap, Q3 2026). Actual savings vary.

While you sleep, your battery quietly feeds your appliances, heating, and hot water. No grid needed. No bill surprise in the morning.
The UK energy market is volatile. A battery puts you in control.
Combined with solar, a battery can cover the vast majority of your annual energy use without touching the grid.
Charge during the day, discharge overnight. Your solar investment works while you sleep instead of wasting export credit.
Most modern batteries with an EPS (Emergency Power Supply) mode keep your lights and essentials running during blackouts.
On smart tariffs like Octopus Agile, charge cheap overnight and discharge during peak hours — earning money from the grid.
Pair with a home EV charger and fill your car with surplus solar. Free miles from the sun, stored in your battery.
Monitor generation, storage, and consumption in real time from your phone. Set charge schedules and export priorities.
Discharging stored solar instead of drawing from the gas-heavy evening grid cuts your household carbon footprint significantly.
Export any excess back to the grid via the SEG tariff and earn on every unit you can't store or use.
We are brand-agnostic and recommend the system that best matches your home, usage, and budget.
From sunlight to storage in four simple stages.
Photovoltaic cells on your roof convert sunlight into direct current electricity throughout the day.
The hybrid inverter converts DC to usable AC for your home — and simultaneously charges the battery with any surplus.
Lithium iron phosphate (LFP) cells store energy efficiently with over 6,000 charge cycles — good for 15+ years of use.
After sunset or during peak tariff periods, the battery releases stored energy to your home — cutting your grid import to near zero.
Yes — in most cases. If you have a standard string inverter we can retrofit an AC-coupled battery (like a Powerwall-style system). If you're open to replacing the inverter, a DC-coupled hybrid setup is more efficient. We survey your existing system and recommend the best approach.
A battery-only installation typically takes 4–6 hours. A combined solar + battery installation usually takes 1–2 days depending on system size and roof complexity.
It depends on the model. Batteries with EPS (Emergency Power Supply) or backup mode can island your home and keep essential circuits running. GivEnergy, SolarEdge, and Fox ESS all offer this — we confirm backup capability at the survey stage.
All batteries we install come with a minimum 10-year manufacturer warranty covering at least 70% capacity retention. Our installation workmanship also carries a 10-year guarantee.
Since October 2023, standalone home battery storage is subject to 0% VAT in the UK when installed alongside a solar PV system on a residential property. We confirm the applicable rate at quote stage.
Yes. We offer 0% APR finance (subject to status) for 24–60 months and longer-term options at competitive rates via our finance partner. See our Finance page for full details and a repayment calculator.
