Cardiff homes and businesses upgrading to solar panels, battery storage or EV chargers often need electrical upgrades to support the new systems safely. GL Solar's NAPIT-approved electricians carry out all required electrical work across Cardiff — from consumer unit replacements and cable upgrades to full rewires and earthing improvements.

Many properties in Cardiff, particularly older terraced homes in areas like Roath, Canton and Splott, still have ageing fuse boards that do not meet current BS 7671 standards. These need upgrading before solar inverters, battery systems or EV chargers can be connected. Our electricians assess your existing installation during the free survey and provide a clear, fixed-price quote for any required upgrades.

We also carry out electrical upgrades as a standalone service across Cardiff. Whether you need a consumer unit replacement, an EICR (Electrical Installation Condition Report), additional circuits for a kitchen extension or a full rewire, our local Cardiff team delivers safe, compliant work with full certification.

All electrical work is completed to BS 7671 standards, fully certified and notified to Building Control where required. We work with all property types across Cardiff — Victorian terraces, 1930s semis, modern new builds and commercial premises — ensuring every installation is safe, efficient and ready for renewable energy.
