Six reasons homeowners make the switch
Battery Storage
Store daytime generation and cheap off-peak import, then use it through the evening peak instead of buying at 27p+ per kWh.
Energy Independence
Generate your own power and insulate your household from price cap swings and future standing charge rises.
Lower Carbon Footprint
The average solar home avoids around 1.5 tonnes of CO₂ every year — the equivalent of driving 4,000 fewer miles.
Added Property Value
Solar and battery homes achieve stronger EPC ratings, and better-rated homes consistently sell faster and for more.
Smart Export Guarantee
Sell surplus generation back to the grid. SEG rates from 15p/kWh add a second income stream to your system.
