Common Electrical Emergencies We Handle
Our emergency electricians regularly deal with a wide range of urgent electrical faults across domestic and commercial properties in London. Below are some of the most common emergency issues we investigate and repair.
Consumer Unit Keeps Tripping
Complete Loss of Power
A sudden loss of power can be caused by multiple issues including main switch faults, damaged circuits, loose connections, or supply-related problems. Our electricians inspect the installation thoroughly to determine whether the fault originates within the property or from the incoming electrical supply.
If your consumer unit repeatedly trips, this usually indicates an underlying electrical fault that requires professional investigation. Common causes include faulty appliances, damaged wiring, overloaded circuits, insulation resistance faults, moisture ingress, or defective RCDs and RCBOs.
At VoltHeat, we carry out systematic electrical testing and fault finding to identify the source of the problem safely and efficientlyIf your fuse board is outdated or frequently tripping, you may benefit from our Consumer Unit Upgrade services.
Burning Smells from Electrical Accessories
Sockets or lighting circuits that stop working unexpectedly may indicate damaged wiring, loose connections, tripped protective devices, or circuit faults. We diagnose and repair faulty electrical circuits safely and professionally.
Water Damage Affecting Electrical Systems
Leaks and water ingress can seriously affect electrical installations and create dangerous conditions. We inspect affected circuits, test the installation where appropriate, and advise on any repairs or replacements required to restore safety.

Professional Electrical Fault Finding
Electrical fault finding is one of the most important parts of emergency electrical work. Many electrical problems are not immediately visible and require professional inspection, testing, and diagnostics to identify the exact cause safely.
At VoltHeat, we use professional testing equipment and systematic fault-finding procedures to investigate electrical issues efficiently and accurately. Proper diagnostics help avoid unnecessary replacements and ensure the root cause of the problem is identified correctly.
Depending on the fault, our investigations may include:
- Continuity testing
- Insulation resistance testing
- Earth fault loop impedance testing
- RCD testing
- Circuit tracing
- Polarity verification
- Visual inspections
- Socket and lighting diagnostics
- Appliance isolation testing
- Consumer unit testing
Electrical faults can develop over time due to wear and tear, loose connections, damaged accessories, overloaded circuits, moisture ingress, or ageing installations. In some cases, faults may appear intermittently and only occur under certain conditions, making professional testing even more important.
Our goal is to restore safety, minimise disruption, and ensure the electrical installation operates correctly and safely following repairs.

Signs You Need an Emergency Electrician
Electrical problems should never be ignored, especially when they may present a safety risk to the property or occupants. In many cases, early warning signs appear before a more serious electrical fault develops.
You should contact a qualified emergency electrician if you notice any of the following:
- Burning smells from sockets or switches
- Buzzing or crackling sounds from electrical accessories
- Consumer unit repeatedly tripping
- Flickering or dimming lights
- Partial or complete loss of power
- Electric shocks from appliances or switches
- Overheating sockets or switches
- Water exposure near electrical installations
- Damaged cables or exposed wiring
- Smoke alarms not functioning correctly
- Frequent circuit overloads
- Sudden appliance failures
Ignoring electrical faults can increase the risk of electric shock, fire hazards, and further damage to the electrical installation. Professional fault finding and testing can help identify the issue safely before it becomes more serious.
At VoltHeat, we provide professional emergency electrical diagnostics and repairs across London for domestic and commercial properties.
Consumer Unit Repairs and Upgrades
Many emergency electrical call-outs are related to older or faulty consumer units. Frequent tripping, overheating, loss of power, or damaged protective devices may indicate that the electrical installation requires professional inspection or upgrading.
