Why it matters
Why use a certified battery storage installer?
Using an MCS-certified installer ensures your battery is correctly specified for your solar array and electrical supply, safely installed, and registered - which matters for warranties, insurance, and any export tariff that requires certified equipment.
Battery Storage in Cornwall - common questions
How much does battery storage cost in Cornwall?
A home battery system in Cornwall typically costs £3,000–£8,000 depending on capacity (most homes fit 5–15kWh). Fitted alongside a new solar array the labour often overlaps, reducing the combined cost.
Is battery storage worth it in Cornwall?
Yes - Cornwall's high solar yields mean systems regularly produce more than a home uses during the day. A battery can lift self-consumption from around 30% to 70%+, and when charged from cheap overnight tariffs it can cut bills further. 0% VAT applies to battery storage until 2027.
Can I add a battery to my existing solar panels?
In most cases, yes. Battery storage can be retrofitted to existing solar PV installations - your installer will check whether your current inverter is compatible or whether an AC-coupled battery is the better route.
Do battery installers need to be certified?
Look for MCS certification alongside electrical accreditation such as NICEIC or NAPIT. Every battery storage installer on Cornwall Green Trades is verified, so you can be confident the work meets current standards.
