Cathays homeowners — including many students, young professionals and landlords — looking to install solar panels, battery storage or EV chargers often need electrical upgrades to ensure safe and compliant operation. GL Solar's NAPIT-approved electricians carry out consumer unit replacements, cable upgrades, earthing improvements and EICR inspections across Cathays, Blackweir and the surrounding central Cardiff area.

Cathays is dominated by large Victorian and Edwardian houses, many converted into HMOs and student flats, alongside some post-war semis and newer apartment blocks. These properties often have electrical installations of mixed ages and conditions — from original wiring in the oldest houses to more recent partial upgrades in converted flats. Before connecting solar inverters, battery systems or EV chargers, a thorough assessment and often significant upgrading is required.

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

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