Did You Know?
- Without an MCS Certificate, you can’t export energy to the grid or take advantage of Smart Export Guarantee (SEG) tariffs.
- Cheap installs often lock you into one supplier. Our systems keep you flexible.
- Solar boosts your home’s value – and can improve your Energy Performance Certificate (EPC) rating.
- With VAT relief, solar and battery installations are more affordable than ever.
Intelligent Battery Storage
Every battery system we install is:
- Custom-designed for your home’s needs. We won’t specify a battery system if it’s not suitable for your energy usage.
- Expandable as your energy usage grows. We can stack and daisy chain the battery system to provide you with added capacity in the future.
- Designed to offer whole-home backup or dedicated supply in case of power outage.
