When You Need an Emergency Electrician in Eltham

Published July 2026 | Emergency Electrician

In the First 10 Minutes

Electrical emergencies move fast. The actions you take in the first few minutes can prevent a minor fault from turning into a fire, a serious injury, or a repair bill that's ten times larger than it needed to be.

Step 1: Don't touch anything you're unsure about. If you can see sparks, smell burning plastic from a socket or switch, or your lights are flickering in a way that suggests a fault rather than a loose bulb, leave the room and don't go back in until you understand what you're dealing with.

Step 2: Go to your consumer unit. Your consumer unit (commonly called the fuse box) is usually in a hallway, under the stairs, or in a kitchen cupboard. Look at the circuit breakers. If one has tripped to a middle or off position, that's your starting point. Don't just reset it without knowing why it tripped in the first place.

Step 3: Cut the power if you need to. If you can smell burning plastic, see a scorch mark on a socket, or hear buzzing or crackling from a wall, switch off the main isolator at the consumer unit. It's the large switch at the top or side of the board. You'll lose all power to the property, but that's the right call.

Step 4: Call 999 if there's smoke or fire. If flames or smoke appear, or the burning smell is getting stronger, get everyone out of the property immediately. Electrical fires can spread invisibly inside walls and ceilings. Call 999, get outside, and do not go back in.

Within the First Hour

Once the immediate danger is under control, this stage is about understanding what you're actually dealing with and making the right calls before you pick up the phone to an electrician.

Assess what happened. Think about what was running when the problem started. Was it a new appliance? Had you recently done any DIY? Was there heavy rain? Water ingress into exterior sockets, damaged cables in lofts, and overloaded circuits are among the most common causes our engineers see on Eltham call-outs. Write down what you noticed, including the time, which appliances were on, and what you heard or smelled. This information speeds up diagnosis significantly.

Check whether it's your problem or the network's. Sometimes what feels like an electrical emergency is a power cut from UK Power Networks, which manages the distribution network across Greater London. Check whether your neighbours have power. If the whole street is out, call UK Power Networks on 105 - it's free and available 24 hours a day. They can confirm whether there's a known fault in the Eltham area. If your neighbours have power and you don't, the problem is inside your property.

Same Day

Once you've confirmed the problem is inside your property and the immediate risk is contained, the priority is getting a qualified electrician in front of the fault.

When you call, be specific. "There's a burning smell from the kitchen socket, it's been there for two hours, and I've switched off the power" gives an engineer far more to work with than "I have an electrical problem."

Prepare your home before the engineer arrives:

1. Clear access to your consumer unit and electricity meter
2. Note which circuits appear affected
3. Gather any recent electrical work certificates - they give the engineer a picture of the installation history
4. Take photos of any visible damage before the engineer arrives, in case you need them for insurance

What to expect to pay. Emergency call-outs in Greater London typically carry higher rates than standard appointments. Expect a call-out charge of around 80 to 120 pounds, with an hourly rate of typically 70 to 120 pounds on top. Out-of-hours work - evenings, weekends, and Bank Holidays - commonly adds 30 to 50 per cent to the standard rate.

A simple fault diagnosis and minor repair, such as a failed socket that needs replacing after a fault, might come in at 150 to 250 pounds total. A more complex job, such as fault-finding across multiple circuits or a partial consumer unit replacement, could reach 400 to 800 pounds depending on the extent of the work. Always ask for a written quote, even if it's sent by text, before any work starts.

The Repair Visit

Knowing what to expect when the electrician arrives helps you work with them more effectively and understand what they're finding.

The initial assessment. A qualified engineer will start with a visual inspection and use a multifunction tester to check circuits. They'll typically look at the consumer unit first, then trace the fault back from the affected area. Our engineers using the Voltrade GoFIX diagnostic approach log findings as they go, which produces a clear record of what was found and why specific work was recommended - useful if the repair needs to be discussed with your insurer afterwards.

Depending on complexity, the initial diagnosis typically takes 30 to 60 minutes.

Common emergency repairs and typical timescales:

• Replacing a damaged socket or fused connection unit: 30 to 60 minutes
• Investigating and repairing a burnt or damaged cable: 1 to 3 hours, depending on where the cable runs
• Replacing a failed consumer unit: typically 3 to 5 hours for a standard domestic installation
• Fault-finding on a complex installation: can take several hours and may need a follow-up visit

What happens after the work. For any notifiable electrical work, the electrician must issue an Electrical Installation Certificate (EIC) or a Minor Electrical Installation Works Certificate. Ask for this before they leave. If they can't provide it, that's a serious concern and worth querying directly.

The Following Week

The week after an electrical emergency is the right time to consolidate and check that everything is properly resolved.

Test every circuit methodically. Turn on lights, sockets, and appliances one by one. If anything trips the consumer unit again, contact your electrician straight away - it suggests the underlying fault wasn't fully resolved.

Check for hidden damage. Some electrical faults, particularly arc faults or sustained overloads, can damage cabling or back boxes that aren't visible from the surface. If the fault involved a wall socket or switch plate, ask your electrician whether the surrounding area should be inspected more closely.

Review your insurance position. If the emergency caused damage to appliances or the property, contact your home insurer. You'll typically need the Electrical Installation Certificate and photographs of the damage. Eltham homeowners with buildings or contents insurance should check their policy carefully - electrical damage from a sudden fault is often covered, but damage resulting from gradual deterioration typically isn't.

Long Term

Most electrical emergencies in residential properties don't appear without warning. They're usually the end result of an installation that's been under stress for some time.

Commission a Periodic Inspection and Testing Report (EICR). An EICR is an independent assessment of your entire electrical installation. For owner-occupied homes, guidance suggests having one every 10 years - but if your property is older, has had multiple owners, or hasn't had documented electrical work in recent memory, doing it sooner makes sense.

Across Greater London, a large proportion of housing stock dates from before the 1970s. EICRs in properties this age frequently flag issues such as unprotected older wiring, missing RCD protection, or consumer units that no longer meet current standards. An EICR typically costs between 150 and 300 pounds for a standard domestic property depending on size.

Consider upgrading your consumer unit. If your consumer unit is more than 15 years old, or uses old-style rewireable fuses rather than modern circuit breakers and RCDs, an upgrade is a sensible conversation to have with your electrician. Modern units with RCDs and arc fault detection devices reduce the risk of the kind of emergency that prompted this article in the first place.

Don't overload circuits. Overloading is one of the most common root causes our engineers identify in Eltham homes. Extension leads daisy-chained together, multiple high-draw appliances sharing one circuit, and DIY adaptors all increase risk over time. As a working rule, don't run more than 3,000 watts from a single socket outlet - that's roughly two appliances drawing 1,500 watts each.

Timeline Questions

How quickly can an emergency electrician get to Eltham?

Response times vary by company and time of day, but most emergency electricians covering Eltham aim to arrive within one to four hours of being called. During business hours, arrival in under two hours is fairly common for properties in and around the Eltham area. Late-night or weekend call-outs may take longer. When you call, ask for an estimated arrival window and confirm the call-out charge upfront before agreeing to anything.

What counts as a genuine electrical emergency?

A genuine electrical emergency is any situation involving an immediate risk to safety or where the property can't be safely occupied. Burning smells, visible scorch marks, sparks, complete loss of power where vulnerable people live, or any situation combining water and electricity all qualify. A socket that's stopped working is inconvenient, but it typically doesn't need an emergency call-out unless it's affecting critical equipment such as medical devices or a central heating system.

Can I stay in my home during an electrical emergency?

It depends on the nature of the fault. If you've isolated the affected circuit and there's no ongoing burning smell or smoke, staying in the property while you wait for an engineer is often fine. But if you can't isolate the fault, if the burning smell persists after switching off the power, or if your consumer unit is sparking or overheating, leave the building and wait outside or at a neighbour's home. Don't take risks with electrical faults in enclosed spaces.

Do I need to contact UK Power Networks as well as an electrician?

Contact UK Power Networks on 105 if you suspect the fault is on the supply side - for instance, if multiple properties nearby are affected, or if the cable bringing power to your property appears damaged. UK Power Networks is responsible for the network up to and including your electricity meter. Everything on your side of the meter is your responsibility and requires a private qualified electrician. If you're unsure which side the fault is on, call 105 first - they can tell you quickly.
