Consumer Unit & Fuseboard Upgrades Across South Wales
At Teslec Electrical Services, we specialise in new consumer unit installations, fuseboard upgrades, and the replacement of outdated or unsafe fuse boxes for domestic and commercial properties across South Wales, covering all areas listed on teslec.co.uk.
An up-to-date consumer unit is essential for the safety, reliability, and performance of any electrical installation. Older fuse boxes often lack modern protection such as RCDs and RCBOs, which are now standard under current UK wiring regulations. Upgrading your consumer unit not only improves electrical safety but also helps protect people, property, and electrical equipment.

We supply and install modern, fully compliant consumer units, designed to meet current electrical demands and regulations. Whether your property requires a straightforward upgrade or a more complex installation, Teslec Electrical Services ensures every fuseboard replacement is carried out safely, efficiently, and with minimal disruption.

Each installation is carefully planned, with all circuits fully tested and clearly labelled to ensure safe operation and future reliability.
