Caerphilly homeowners looking to install solar panels, battery storage or EV chargers often need electrical upgrades to ensure their property's wiring and consumer unit can safely support the new systems. GL Solar's NAPIT-approved electricians carry out consumer unit replacements, cable upgrades, earthing improvements and EICR inspections across Caerphilly town and the surrounding county borough.

Caerphilly's housing stock includes a mix of traditional stone-built homes, post-war council estates and newer developments — each presenting different electrical challenges. Older properties in areas like Bedwas, Ystrad Mynach and Abertridwr often have ageing fuse boards and insufficient cable capacity for modern solar inverters and battery systems. Our electricians assess every property individually and recommend the most cost-effective upgrade path.

We provide free electrical assessments as part of our solar and battery installation service across Caerphilly. During the survey, our electricians check your consumer unit capacity, cable sizes, earthing arrangements and overall installation condition. Any required upgrades are quoted upfront with a fixed price — no surprises, no hidden costs.

Beyond electrical work for renewable energy, we also offer standalone electrical services across Caerphilly — including EICR inspections, consumer unit replacements, additional circuits and full rewires. All work is completed to BS 7671 standards, fully certified and notified to Building Control where required.
