Domestic & Commercial
Rewiring in South Wales
Certified Local Electricians – Professional Rewiring Services for Homes & Businesses Across Cardiff, Newport, Swansea & Surrounding Areas
What Is Rewiring?
Rewiring is the process of replacing old, outdated, or unsafe electrical wiring throughout your property with new cables and components that meet current safety standards. This essential electrical work ensures your domestic or commercial property's electrical system is safe, efficient, and compliant with the latest 18th Edition wiring regulations.
At Megalec Electrical Solutions, we specialise in both full rewiring and partial rewiring services for domestic and commercial properties across South Wales. A full rewire involves replacing all electrical cables, sockets, switches, and the consumer unit throughout the entire property. A partial rewire focuses on specific areas or circuits that need updating – ideal for extensions, renovations, or targeted upgrades.
Whether you need a complete rewire for an older property, targeted upgrades for specific areas, or rewiring as part of a renovation or commercial fit-out, our NAPIT-approved electricians provide professional rewiring services throughout Cardiff, Newport, Swansea, Bridgend, and surrounding areas in South Wales. We handle everything from initial inspection through to final certification, ensuring your property is safe and fully compliant.
Signs You Need a Rewire
Watch out for these warning signs in your property
Old Fuse Board
If your property still has an old-style fuse box with rewirable fuses instead of a modern consumer unit with circuit breakers, it’s time for an upgrade.
Flickering Lights
Lights that flicker or dim when appliances are switched on indicate potential wiring issues that need professional attention.
Burning Smells
Any burning smell from sockets, switches, or the fuse box is a serious warning sign requiring immediate electrical inspection.
Frequent Tripping
Circuit breakers that trip frequently suggest overloaded circuits or faulty wiring that needs investigation.
Old Wiring Colours
Properties with old red and black wiring (pre-2004) or fabric-covered cables need rewiring to meet current standards.
Property Over 30 Years
Properties over 30 years old with original wiring should be inspected and likely need rewiring for safety and compliance.
