Llanishen homeowners looking to install solar panels, battery storage or EV chargers often need electrical upgrades to ensure their property can safely support the additional load. GL Solar's NAPIT-approved electricians carry out consumer unit replacements, cable upgrades, earthing improvements and EICR inspections across Llanishen, Lisvane and the surrounding north Cardiff area.

Llanishen features a mix of post-war semis, 1970s detached homes and newer developments, many with electrical installations of varying ages and capacities. Properties in areas near Ty Glas Road, Llanishen village and the newer estates often have consumer units and cabling that need upgrading before solar inverters, battery systems or EV chargers can be safely connected.

We provide free electrical assessments for Llanishen homeowners as part of our solar and battery installation service. Our electricians inspect your existing consumer unit, cable sizes, earthing arrangements and overall installation condition during the survey. Any required upgrades are quoted upfront with a fixed price — no hidden costs.

GL Solar also offers standalone electrical services across Llanishen — including EICR inspections, consumer unit replacements, additional circuits and full rewires. All work is completed to BS 7671 standards by NAPIT-approved electricians, with full certification and Building Control notification where required.
