Signs You Need a Rewire
Watch out for these warning signs in your Cardiff property
Old Fuse Board
Many Cardiff Victorian and Edwardian properties still have old-style fuse boxes. A modern consumer unit with RCD protection is essential for safety.
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
Many Cardiff properties are over 30 years old with original wiring that should be inspected and likely needs rewiring for safety.
