Solar & Battery FAQs
The average domestic solar PV system without batteries (around 4kW) costs between £4,000 and £6,000, depending on the equipment. Prices vary based on roof type, panel quality, and additional site specific installation requirements such as cable routes or scaffolding.
Battery storage will typically cost between £600 and £750 per kWh.
You may find increases in the cost if you require emergency back up facilities, optimisers or have multiple roofs.

EV Charging FAQs
Domestic EV Charging FAQs (Homeowners
Yes, if you have off-street parking and a suitable electrical supply, you can install a home EV charger. Most homeowners opt for a 7kW charger, which balances cost and charging speed. You’ll need a certified installer and possibly minor electrical upgrades.
With a 7kW home charger, most EVs charge from 0 to 80% in 6–8 hours, perfect for overnight charging. A standard 3-pin plug is slower, taking up to 24 hours and runs the risk of burning.
