When You Need an Emergency Electrician in Exeter

Published July 2026 | When You Need an Emergency Electrician

It's half nine on a Tuesday evening and half the lights in your Exeter home have just cut out. You head to the consumer unit under the stairs, reset the tripped breaker, and within thirty seconds it trips again. Now you're standing in the dark wondering whether this is something you can fix yourself or whether it needs a phone call tonight.

That scenario plays out in homes across Devon more often than people realise, and the answer isn't always obvious. Some electrical problems can wait until morning. Others need a qualified electrician at your door within the hour. Knowing the difference matters - not just for your wallet, but for your safety.

Understanding What's Actually Happening

Your home's electrical system is built around circuits, each one protected by a breaker or fuse in the consumer unit (sometimes called the fuse board or fuse box). When something goes wrong - too much current, a fault in the wiring, or a problem with an appliance - the breaker trips or the fuse blows. That's the system working exactly as it should: cutting power before anything overheats, sparks, or catches fire.

A tripped breaker is a symptom, not a diagnosis. It tells you something is wrong on that circuit, but it doesn't tell you what. That's where homeowners often get into trouble - resetting the breaker repeatedly without understanding why it tripped in the first place.

Modern consumer units in the UK are required to include RCD (Residual Current Device) protection under the 18th Edition Wiring Regulations (BS 7671). An RCD monitors the balance of current flowing in and out of a circuit and trips almost instantly if it detects a fault - typically within 40 milliseconds. It's one of the most effective pieces of safety kit in your home. But when an RCD trips, it's often covering multiple circuits, which is why a single fault can suddenly take out your sockets, your lighting, and your immersion heater all at once.

Understanding whether you're dealing with a tripped MCB (Miniature Circuit Breaker), a tripped RCD, or something more serious is the first step in working out what to do next.

The Most Common Causes of Electrical Emergencies

Not every electrical fault is a true emergency, but these are the problems our engineers see most often when homeowners call us out in a hurry.

An Overloaded Circuit

Circuit overloads happen when too many appliances draw power through the same set of wires at the same time. Kitchen circuits are particularly vulnerable - run a toaster, kettle, microwave, and air fryer simultaneously and you're pushing the limits of what a standard 32-amp circuit can handle. The breaker trips as a protective measure.

In most cases you can identify this yourself: if the breaker resets without immediately tripping again and nothing seems visibly damaged, an overloaded circuit is the likely culprit. Spreading appliances across different sockets on different circuits usually resolves it. But if you're regularly hitting this problem, it's a signal your home's wiring may not be adequate for modern demand - a common issue in older Exeter properties, particularly Victorian and Edwardian terraces that haven't been rewired in decades.

A Faulty Appliance

A single faulty appliance is one of the most common reasons an RCD trips. The appliance develops an internal fault - a damaged element, a worn motor, a compromised seal - and starts leaking current to earth. The RCD detects this and cuts the power to protect you.

You can often identify the guilty appliance through process of elimination. Unplug everything on the affected circuit, reset the RCD, then plug appliances back in one at a time. When the RCD trips again, you've found your faulty device. Common culprits include washing machines, dishwashers, tumble dryers, and electric ovens. Brands like Hotpoint, Beko, and Bosch are all reliable enough, but any appliance can develop faults over time - particularly after 8 to 10 years of regular use.

Do not keep using an appliance that trips your RCD. Get it tested or replaced. A faulty appliance left running is a fire risk.

Damaged or Ageing Wiring

Older wiring is a serious concern in many Exeter homes. Properties built before the 1970s commonly have rubber-insulated or aluminium wiring that degrades over time. Rubber insulation becomes brittle and can crack, leaving live conductors exposed inside your walls. Signs of ageing wiring include frequent unexplained trips, sockets that feel warm to the touch, flickering lights where the bulbs are fine, and visible scorching around sockets or switches.

If your home hasn't had an Electrical Installation Condition Report (EICR) carried out in the last 10 years - or if you've never had one done - you simply don't know what condition your wiring is in. For rental properties in Devon, landlords are legally required to have an EICR carried out every five years. For owner-occupiers, it's strong advice rather than a legal requirement, but treating it as optional isn't worth the risk in an older property.

Water Ingress and Damp

Devon's climate means damp is a real factor for many homeowners, particularly in older properties. Water and electricity are a dangerous combination. When damp gets into a wall near wiring, or water drips onto a socket, switch, or junction box, it creates a path for current to travel where it shouldn't. This can trip an RCD, but it can also cause smouldering inside walls that isn't immediately visible.

If you've had a leak - a burst pipe, an overflowing bath, water coming through the roof - and you then notice electrical problems, treat it as a potential emergency. Don't attempt to reset breakers or restore power to affected areas without professional assessment first.

A Failing Consumer Unit

Consumer units have a lifespan. Older fuse boards with rewireable fuses offer minimal protection compared to modern units with MCBs and RCDs. If your consumer unit is over 25 years old, has a wooden back, or contains older-style ceramic fuses, it's well past the point where it should be replaced.

A consumer unit that repeatedly fails to hold resets, has breakers that won't stay up, or shows signs of burning or discolouration around the terminals is a genuine safety hazard. Consumer unit replacement in the UK typically costs between 400 and 700 pounds depending on the size of the installation and whether any additional work is needed alongside it.

Solutions That Actually Work

Before you call an emergency electrician, there are a few checks worth doing yourself - but only where you can do so safely.

If a single breaker has tripped, work through these steps:

1. Turn off or unplug all appliances on the affected circuit before attempting a reset.
2. Locate the consumer unit and identify which breaker has tripped - it will be in a middle or fully off position compared to the others.
3. Push the breaker firmly to the off position first, then back to on.
4. If it resets and holds, plug your appliances back in one at a time to identify whether one of them caused the trip.
5. If the breaker trips immediately on reset, or won't reset at all, stop and call a qualified electrician. Do not keep forcing it.

If you can smell burning from a socket, switch, or consumer unit, or you can see scorch marks, sparking, or smoke, skip the above entirely. Turn off the main switch at the consumer unit if it's safe to reach, and call an emergency electrician straight away. If there's smoke or fire, call 999 first.

Our engineers use Voltrade's GoFIX diagnostic tool to assess fault descriptions remotely before a visit. This often helps narrow down the likely cause and means the right equipment and parts come with us first time - which matters when you're sitting without power late in the evening.

When You Need Professional Help vs Sorting It Yourself

Most electrical work beyond basic troubleshooting should involve a qualified electrician - not because homeowners can't follow instructions, but because the regulations require it and the risks are real.

Under Part P of the Building Regulations in England, most electrical installation work in dwellings is "notifiable" - meaning it must be carried out by a registered competent person or notified to your local building control authority. This includes replacing a consumer unit, adding new circuits, and any electrical work in kitchens and bathrooms. A registered electrician self-certifies their own work. DIY installation requires a building control application, an inspection fee, and leaves you exposed if your home insurance receives a subsequent claim related to that work.

You can typically sort it yourself if: a breaker trips and resets cleanly after you identify and remove an overloaded appliance; a bulb has blown and you're replacing it; or a socket faceplate is loose and you're tightening the screws with the circuit turned off.

You need a professional if: a breaker won't reset or trips immediately; an RCD trips repeatedly with no obvious cause; you can smell burning from any electrical fitting; you've had flooding or a significant leak near electrical equipment; you're seeing sparks; or you need any new wiring, additional sockets, or a consumer unit replacement.

When in doubt, call. A diagnostic visit from a qualified electrician costs considerably less than dealing with the aftermath of a fire.

What to Expect from a Repair Visit

If you've called an emergency electrician to your Exeter home, here's what the visit typically looks like.

Response times vary by contractor and time of day, but most local electrical firms aim to reach genuine emergencies within one to four hours. Out-of-hours call-outs - evenings, weekends, and bank holidays - carry a premium. You can commonly expect a call-out fee of between 60 and 120 pounds on top of the hourly labour rate, which in the Devon area typically sits between 50 and 90 pounds per hour. Out-of-hours rates can run 50 to 100 percent above the standard daytime charge, so a late-night visit of two hours might cost you between 200 and 350 pounds all in.

When the electrician arrives, they'll start with a diagnostic assessment. They'll ask what happened, when it started, and whether anything changed beforehand - a new appliance, recent building work, a plumbing leak. They'll inspect the consumer unit, test circuits, and use specialist equipment to trace faults within the wiring if needed.

Simple faults - a tripped RCD caused by a faulty appliance, a failed socket needing replacement - can typically be resolved in under an hour. More involved problems, like tracing a fault in ageing wiring or replacing a consumer unit, will take longer and may need a follow-up visit to complete all the required work.

Make sure any electrician you use is registered with NICEIC, NAPIT, or ELECSA. These are the recognised competent person schemes for electrical work in England. A registered electrician will provide you with a certificate on completion - keep it with your property documents, as you'll need it if you ever come to sell.

Common Questions from Exeter Homeowners

How much does an emergency electrician cost in Exeter?

Emergency call-out fees in the Exeter area typically range from 60 to 120 pounds, with hourly labour rates commonly between 50 and 90 pounds. Out-of-hours visits - evenings, weekends, and bank holidays - usually carry a premium of 50 to 100 percent above standard rates. Always ask for a written estimate before work begins, and check whether VAT is included in any figure quoted to you over the phone.

How quickly can an emergency electrician reach me in Exeter?

Most electricians covering Exeter and the wider region aim to respond to genuine emergencies within one to four hours. During busy periods or late at night it may take longer. If you're without power and vulnerable people are in the property - young children, elderly relatives, anyone dependent on medical equipment - mention this when you call. Many contractors will prioritise accordingly when the situation warrants it.

Can I reset my own consumer unit when a breaker trips?

Yes, attempting to reset a tripped MCB or RCD in your consumer unit is a safe first step, provided the area around the unit is dry and you're not in any immediate danger. Always unplug appliances on the affected circuit before you try. If the breaker won't stay reset, or trips again immediately, stop and call a qualified electrician rather than continuing to force it. Repeatedly resetting a breaker on a genuinely faulty circuit can cause further damage and increases fire risk.

What counts as a genuine electrical emergency in Devon?

A genuine electrical emergency is any situation where there's an immediate risk to safety - burning smells from fittings or the consumer unit, visible sparking or scorch marks, water near electrical equipment, exposed wiring, or a complete power loss in a home where vulnerable people are present. A single tripped breaker that resets cleanly is not typically an emergency. If you're unsure, most qualified electricians are happy to advise over the phone before you commit to a call-out.
