Rules & regulations
- Installation is notifiable electrical work; the DNO must be notified (G98/G99)
- Batteries charged from the grid and discharged at peak need a smart tariff to make the maths work, no regulation, just arithmetic
Snap tips
- Without solar, a battery only pays back on a genuinely cheap overnight tariff, run the numbers first
- Size to your evening usage, not the biggest box you can afford
