When a power failure or a burning smell occurs, you need a prompt Emergency Electrical Repair to ensure your property remains safe and functional. Our team operates across London and the M25 corridor, providing 24-hour support for homeowners, landlords, and commercial managers who encounter sudden, dangerous, or disruptive electrical faults that cannot wait until morning.
Electrical systems are the heartbeat of the modern building, but they are also subject to wear, environmental stress, and component failure. An Emergency Electrical Repair is not just about restoring the lights; it is a critical safety intervention designed to identify the root cause of a fault and prevent the risk of fire or electric shock. Whether you are dealing with a consumer unit that refuses to reset or a complete loss of power, our qualified electricians are equipped to stabilise the situation and provide professional solutions.
Recognising the Signs of an Electrical Emergency
Identifying when a situation requires an immediate Emergency Electrical Repair is vital for property safety. Often, the signs are subtle before they become critical. One of the most common indicators is a persistent burning smell, often described as 'fishy' or like scorched plastic, emanating from sockets, switches, or the consumer unit. This is a sign of overheating and potential combustion within the wiring.
Other warning signs include audible buzzing or crackling noises behind walls, which may indicate arcing. Visible scorch marks or discolouration on faceplates suggest that high temperatures are being reached due to loose connections or overloaded circuits. If your lights are flickering excessively or dimming when other appliances turn on, it may indicate a serious issue with the neutral connection or the main incoming supply.
- —Persistent burning smells or smoke from outlets
- —Visible sparks when plugging in or using appliances
- —Discoloured, brown, or melted socket faceplates
- —Frequent, unexplained tripping of the RCD or circuit breakers
- —Audible buzzing, humming, or clicking from the fuse box
- —Total loss of power affecting only your property
Common Causes of Sudden Electrical Failure
Electrical faults can stem from various sources, ranging from aged infrastructure to external environmental factors. In many London properties, particularly older builds, the wiring may not be designed to handle the load of modern high-power appliances, leading to thermal stress and insulation breakdown. Over time, the protective coating on cables can perish, leaving live conductors exposed.
Water ingress is another leading cause for an Emergency Electrical Repair. Leaks from flat roofs, burst pipes, or failing bathroom seals can find their way into light fittings or junction boxes, causing immediate short circuits. Additionally, loose terminations—where wires have physically vibrated loose from their terminals over years of use—create high-resistance connections that generate significant heat and pose a major fire risk.
The Risks of Ignoring Faulty Electrics
Ignoring a suspected electrical fault can have devastating consequences. The primary risk is an electrical fire; according to UK fire statistics, a significant percentage of domestic fires are caused by faulty wiring or appliance misuse. When a connection is loose or a cable is damaged, electricity can 'arc' across the gap, creating intense heat that ignites surrounding building materials.
Beyond fire risks, there is the immediate danger of electric shock. If an earthing system is compromised or if a fault develops in a metal-cased appliance without the RCD tripping, the external surfaces could become live. This creates a lethal environment for occupants. Professional intervention ensures that these hidden dangers are identified using calibrated testing equipment that the naked eye cannot replicate.
What to Check Before Calling an Electrician
Before requesting an Emergency Electrical Repair, there are a few safe checks you can perform to determine the scope of the problem. First, check if your neighbours have power; if the streetlights and surrounding houses are dark, the issue lies with the National Grid or your local Distribution Network Operator (DNO), and you should call 105.
If the issue is isolated to your property, locate your consumer unit (fuse box). Check if any switches have moved to the 'off' position. You can try to reset a tripped RCD once. If it trips again immediately, do not force it to stay up. This is a safety mechanism doing its job. You should also unplug the last appliance you were using before the power failed, as a faulty toaster or kettle is often the culprit.
- —Check 105.com or call 105 to rule out a local area power cut
- —Look for 'off' switches on your consumer unit
- —Unplug recently used appliances to see if the fault clears
- —Ensure your prepaid meter (if applicable) has sufficient credit
- —Never attempt to unscrew faceplates or touch internal wiring yourself
What Our Electricians Do During a Call-Out
When our electrician arrives for an Emergency Electrical Repair, their first priority is the safety of the occupants. They begin with a visual inspection, followed by a series of diagnostic tests using a Multi-Function Tester (MFT). These tests measure insulation resistance, continuity, and earth fault loop impedance to pinpoint exactly where the circuit is failing.
Once the fault is located, the electrician will explain the situation and the necessary steps to rectify it. In many cases, a 'first-time fix' is possible by replacing a faulty socket, tightening a loose connection, or bypassing a damaged section of a circuit. If a permanent repair requires specific parts that are unavailable out-of-hours, the electrician will safely isolate the dangerous circuit, ensuring the rest of the property has power and is safe until a full repair can be completed.
Safety First: When to Call Emergency Services
It is important to distinguish between a technical electrical fault and a life-threatening emergency. If you see active flames, thick smoke, or if an electrical fire has started, you must immediately evacuate the building and call 999. Do not attempt to extinguish an electrical fire with water, as this carries a high risk of electrocution.
If you suspect a gas leak in addition to an electrical fault, do not operate any electrical switches (including light switches), as the small spark generated within the switch could ignite the gas. In these instances, call the National Gas Emergency Service. For all other non-combustion electrical failures, such as a loss of sockets, persistent tripping, or a smell of fishy plastic, our 24/7 team is ready to assist.
Commercial and Landlord Emergency Requirements
For business owners and landlords in London, an electrical failure is not just an inconvenience; it is a liability and a potential loss of revenue. We provide Emergency Electrical Repair services for shops, offices, and rental properties to ensure compliance with the Electricity at Work Regulations 1989 and the Landlord Gas and Electrical Safety legislation.
A loss of power to server rooms, security systems, or commercial refrigeration requires immediate attention to prevent data loss or stock spoilage. Our electricians understand the urgency of these situations and work efficiently to restore power while ensuring all work complies with BS 7671 (The IET Wiring Regulations).

Frequently asked questions
How long does an emergency electrical repair take?
The duration depends on the complexity of the fault. Most diagnostic tasks and minor repairs are completed within 1 to 2 hours. If the fault is deep within the building structure, the electrician will focus on making the site safe first.
Can I try to fix a flickering light myself?
You can safely check if the bulb is loose or needs replacing (once the switch is off and the bulb is cool). However, if the flickering persists with a new bulb, it may indicate a loose wire or a failing ballast, which requires a professional to investigate.
Is a tripped RCD always an emergency?
If you cannot reset the RCD and it leaves you without light, heat, or the ability to use essential medical equipment, it is considered an emergency. If you can safely isolate the faulty circuit and keep the rest of the house running, it may be able to wait until standard hours.
Why does my fuse box smell like burning plastic?
This is often caused by a 'loose connection' which creates heat through resistance, melting the plastic insulation or the casing of the circuit breaker. This is a severe fire risk and requires an immediate emergency call-out.
Do you cover all areas inside the M25?
Yes, our emergency team covers all London boroughs and the surrounding areas within the M25 motorway, providing 24/7 support for residential and commercial properties.
