Signs You Need a Rewire

Watch out for these warning signs in your Merthyr Tydfil property

Old Fuse Board

If your Merthyr Tydfil 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.
