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

Llantrisant and nearby areas like Talbot Green, Pontyclun and Brynsadler have a mix of traditional Welsh cottages, post-war semis and newer developments. Many older properties still have outdated fuse boards and undersized cables that cannot safely support modern solar inverters, battery systems or EV chargers. Our electricians assess every property during the free survey and recommend the most cost-effective upgrade path.

We provide clear, fixed-price quotes for all electrical work in Llantrisant. Common upgrades include consumer unit replacement with modern RCD and RCBO protection, cable capacity increases for solar and battery connections, additional circuits for EV charging points, and earthing improvements to meet current BS 7671 standards.

Beyond electrical work connected with renewable energy, GL Solar offers standalone electrical services across Llantrisant — including EICR inspections, consumer unit upgrades, additional circuits and full property rewires. All work is completed by NAPIT-approved electricians with full certification and Building Control notification.
