Electrical emergencies don't wait for business hours. Our 24/7 emergency electrician service covers Cardiff and South Wales with rapid response times — typically 1–2 hours. From total power loss and burning smells to exposed wiring and water damage, we arrive equipped to diagnose, make safe, and repair on the spot where possible.
When to Call an Emergency Electrician
Electrical emergencies require immediate professional attention. Call our 24/7 emergency line if you experience total power loss to your property, burning smells from sockets, switches, or the consumer unit, exposed or sparking wiring, electric shocks from appliances or fittings, water ingress into electrical systems, smoke or scorch marks around electrical components, persistent tripping that prevents power restoration, or post-storm damage to external cables or supplies.
Never attempt to repair electrical emergencies yourself. Even if the power appears to be off, residual charge in capacitors and stored energy in circuits can cause serious injury. Our emergency electricians are trained to make installations safe before carrying out repairs, protecting you and your property from further harm.
We cover Cardiff and all surrounding areas including Newport, Barry, Caerphilly, Penarth, Pontypridd, Bridgend, and the valleys. Our central Cardiff base and satellite teams ensure rapid response regardless of your location. For genuine emergencies, we prioritise dispatch and aim to be with you within the hour.

Gareth's service was excellent — he came on time, kept me updated via text of what time to expect him, installed the light fitting with the minimum of fuss and I feel was great value for money. No complaints, will use again.

Gareth from Cardiff Electrical Home Rewire recently completed a full rewire of our house and we couldn't be happier with the service. From start to finish, Gareth was fantastic. His communication was excellent throughout the whole job.

Recently had a full rewire. Gareth and his team were professional from start to finish and kept you up to date at every opportunity. They tidied up at any given time, along with wearing coverings for their footwear, so much respect for our home.

What Happens If You Delay Emergency Electrician 24/7 Cardiff?
Ignoring electrical issues is one of the most common — and dangerous — decisions property owners make. Here's what you risk by waiting.
Fire from Electrical Faults
Arcing faults, overloaded cables, and damaged sockets can ignite fires within minutes. Delaying emergency response increases property damage and life risk.
Fatal Electric Shock
Exposed live conductors and water-damaged electrics create immediate fatality risks. Only a qualified electrician can safely isolate and repair these hazards.
Carbon Monoxide Risk
Power loss to boilers can disable safety shut-offs. Attempting DIY repairs on heating electrics can create dangerous CO risks alongside electrical hazards.
Property Damage Escalation
What starts as a minor fault can escalate to major damage if not addressed promptly. A tripping RCD may indicate a developing fire risk behind walls.
Invalid Insurance
DIY repairs on emergency faults can invalidate insurance, leaving you liable for all repair costs and any consequential damage.
Extended Downtime
Without emergency response, power loss can last days, spoiling food, disabling heating, and preventing remote working — with significant hidden costs.

Common Emergency Faults We Repair
Total power loss is often caused by a blown cut-out fuse, failed main switch, or DNO supply issue. We diagnose whether the fault is internal or external and restore power safely. Burning smells usually indicate loose terminations creating heat. We locate the affected circuit, isolate it, and repair the connection. Persistent RCD tripping suggests an earth fault — we use insulation resistance testing and divide-and-conquer methods to isolate the affected circuit. Water damage requires careful drying, replacement of affected components, and full testing before restoration. Post-storm damage may involve overhead cable damage or supply issues that require DNO coordination.
Our Emergency Response Protocol
When you call our emergency line, we ask targeted questions to assess severity and prepare the responding electrician. For life-threatening situations (exposed live conductors, smoke, or fire), we advise immediate evacuation and contact emergency services. Our electrician arrives with a fully stocked van containing common replacement parts, testing equipment, and temporary supply solutions. We always make the installation safe before leaving — if a permanent repair requires parts we don't have, we install a temporary safe supply and schedule a return visit. All emergency work is documented and certified, with full reports provided for insurance and warranty purposes.
