Battery storage
Home Battery Storage Installation
A solar and battery system in every home could produce more power than every power station combined.
More than just storage
Batteries store power for when you need it.
You may think that's all they can do.
When sized and set up correctly for your home, a solar battery continues to save you money, day and night, all year round.
Vertically stacked modular systems are a popular choice. They allow for future expansion, save valuable floor space, and offer more precise capacity options to match your home.

PREMIUM BRAND
Smart tariff shifting dramatically cuts your bills and maximises the value of your solar system.
In winter, your battery can charge overnight on a cheap off-peak tariff, then power your home during expensive peak hours.
You'll use more of the free energy you generate and rely less on the grid when electricity is most expensive.
Charge overnight
Use cheap off-peak tariffs to charge your battery at night for use during the day when generation is low. This smart tariff-shifting cuts your bills even when the sun isn’t shining.
Outage protection
Your battery acts as a backup power supply. Keep essential circuits such as lights, fridge, Wi-Fi, medical equipment, or security systems running safely when the grid goes down.
10-year warranty
Every battery we install comes with a 10 year warranty as standard. We only use premium, reliable brands with excellent support and proven long-term performance.

Costs & payback
What a battery actually costs.
Battery pricing depends on usable capacity, whether the inverter is being replaced, and how much backup functionality you want. Retrofits to an existing solar system are usually the simplest and cheapest route.
Typical payback sits at around 6 to 10 years, driven mainly by your tariff. Homes on a smart off-peak tariff pay back fastest because the battery earns twice: storing your own solar in summer and cheap overnight units in winter.
Get a battery quote| System | Usable capacity | Installed price |
|---|---|---|
| Battery retrofitAdded to an existing solar PV system with a compatible or AC-coupled inverter. | 5–6 kWh usable | from £4,000 |
| Mid-size storageThe most common choice for a 3–4 bedroom home on a smart off-peak tariff. | 10–13 kWh usable | from £6,500 |
| Whole-home + backupLarger capacity with grid-backup switchover to keep essentials running in an outage. | 15–20 kWh usable | from £10,000 |

Smart Export Guarantee
Get paid for every unit you don't use.
The Smart Export Guarantee (SEG) is a government-backed scheme that pays you for surplus electricity your system exports to the grid. Every kWh you don't use at home earns you money from your energy supplier.
Typical export rates
15p–30p per kWh depending on your supplier and tariff.
Paid quarterly
Direct credit to your bill or bank account. No paperwork.
We register you
We handle the MCS certificate and DNO notification needed to apply.
