Why Choose Battery Storage?

Maximise your energy independence and savings

💰
Slash Your Energy Bills

Store cheap off-peak electricity and use it during expensive peak hours. Proven savings of up to 75% on energy costs.

Power When You Need It

Use stored solar energy in the evening when the sun goes down. Never waste the electricity your panels generate.

🏠
Energy Independence

Reduce reliance on the grid and protect against rising energy prices. Ideal for off-grid properties.

🔄
Smart Load Shifting

Charge when electricity is cheap, use when prices rise. Compatible with Octopus Agile and other smart tariffs.

🔌
Backup Power

Keep essential appliances running during power cuts. Peace of mind when the grid goes down.

🛡️
Long Lifespan

Modern batteries last 10+ years with minimal maintenance. Up to 40,000 cycles—equivalent to 50 years of use.

How Battery Storage Works

Battery systems store excess electricity for use when you need it most—during peak hours, at night, or during outages.

1
Generate or import electricity

Solar panels generate power, or you import cheap off-peak electricity

2
Store in your battery

Excess energy charges your battery instead of being exported

3
Use when needed

Draw stored power in the evening or during peak rates

4
Export excess and earn

Sell surplus electricity back to the grid with SEG

How Battery Storage Works
Solar PV, Heat Pump and Battery Storage
⚡ The Holy Trinity

Solar PV + Heat Pump + Battery

The ultimate renewable energy system. Generate free electricity with solar, store it in your battery, and power your heat pump—achieving virtually zero-cost heating, hot water, and electricity all year round.

Free daytime heating – Heat pump runs on solar
Store for evening use – Battery powers heat pump at night
Near-zero energy bills – Generate, store, and use your own power
Complete independence – Reduce grid reliance to almost zero

Frequently Asked Questions

Everything you need to know about battery storage

A typical home battery system costs between £5,000-£12,000 including installation, depending on capacity. The Tesla Powerwall (13.5kWh) typically costs around £10,000-£12,000. Smaller 5kWh systems start from around £5,000. With 0% VAT until 2027, you save 20% on these costs.

Yes! Batteries can be retrofitted to most existing solar PV systems. We'll assess your current inverter and recommend whether to add an AC-coupled battery or upgrade your inverter for a hybrid system.

Modern lithium batteries typically last 10-15 years, with manufacturers guaranteeing 70-80% capacity retention after 10 years. The Tesla Powerwall comes with a 10-year warranty. Sunamp thermal batteries offer up to 40,000 cycles—equivalent to 50+ years.

It depends on the system configuration. Some batteries like the Tesla Powerwall can provide backup power during outages, but this requires specific installation. We can configure your system for blackout protection if this is a priority.

Load shifting means charging your battery when electricity is cheap (overnight on Octopus Agile, for example) and using that stored energy during expensive peak hours. This can save 50-75% on electricity bills compared to standard tariffs.

Electrical batteries (like Tesla Powerwall) store electricity to power any appliances. Thermal batteries (like Sunamp) store heat for hot water and heating. Thermal batteries are often more cost-effective if your main goal is heating and hot water.
