A power outage can stop a household in its tracks. The lights go out, the boiler may stop, the Wi-Fi disappears and it is not always clear whether the problem is inside your property or affecting the wider area. The right first steps protect your family, prevent further damage and help get the fault resolved without unnecessary delay.
Start by working out where the power outage is
Before touching your consumer unit, look for simple signs that show whether the supply problem is local to your home. Check whether neighbouring properties have lights on, whether streetlights are off and whether your prepayment meter has credit if you use one. If the whole street appears affected, the issue is likely with the electricity network rather than your own wiring.
In the UK, you can call 105 to report or check a local electricity supply fault. This puts you through to the relevant network operator. They can confirm whether there is a known issue, advise on estimated restoration times and tell you if engineers are attending.
If your neighbours still have power, or only part of your home has lost electricity, the fault may be within your installation. A tripped circuit breaker, faulty appliance, damaged cable or ageing electrical equipment could be responsible. This is when a qualified electrician can investigate safely.
Make the property safe first
Do not assume a loss of power is harmless. Electrical faults sometimes come with warning signs that need prompt action, particularly if the supply has failed suddenly or repeatedly.
If you smell burning, see smoke, notice sparking, hear crackling from sockets or the consumer unit, or find signs of heat damage, keep clear of the area. If it is safe to do so, switch off the main isolator at the consumer unit. Do not touch exposed wiring, attempt a repair or pour water on an electrical fire. Leave the property and call 999 if there is an immediate risk to life, fire or property.
For a straightforward outage with no danger signs, use torches rather than candles where possible. Candles create an avoidable fire risk, especially around children, pets, curtains and busy hallways. Keep fridge and freezer doors closed too. A closed fridge should generally keep food cold for around four hours, while a full freezer holds its temperature for longer than a partly filled one.
Unplug sensitive electronics such as televisions, computers and chargers if the outage is likely to continue. When power returns, a surge can occasionally damage equipment. Leave one light switched on so you know when the supply has been restored.
Check your consumer unit carefully
A consumer unit is designed to disconnect power when it detects a problem. That can be frustrating, but it is doing an important safety job. Never force a switch into the on position or repeatedly reset a breaker that keeps tripping.
First, look for a switch that is down or sitting between the on and off positions. Turn it fully off, then back on once. If it stays on, the trip may have been caused by a temporary issue. If it trips again straight away, leave it off.
The next step is to unplug appliances on the affected circuit, particularly anything recently used or newly installed. Kettles, toasters, washing machines, tumble dryers, extension leads and outdoor equipment are common sources of faults because they combine heat, moisture or wear with regular use. With everything unplugged, try resetting the breaker once more.
If the circuit holds, reconnect appliances one at a time. Should the power trip when a particular item is plugged in, stop using it until it has been checked or replaced. If the breaker still will not reset with appliances unplugged, the problem may be in the fixed wiring, a socket, a light fitting or the consumer unit itself. That requires professional fault finding.
Why repeated tripping should not be ignored
A circuit that trips repeatedly is not merely inconvenient. It may be identifying a damaged cable, loose connection, water ingress or fault that could worsen if left unresolved. Older properties can have added complications, such as wiring that has been altered over many years or circuits that no longer suit modern household demand.
A qualified electrician uses proper test equipment to trace the cause without guesswork. The goal is not simply to get the switch back on, but to establish why it tripped and make the installation safe to use again.
When the fault is likely outside your home
A neighbourhood outage can be caused by storm damage, roadworks, equipment failure or planned network work. Your network operator is responsible for the electricity supply up to the point it enters the property. An electrician cannot repair a fault on the public distribution network, but can help if damage or a separate fault is found within your home after supply is restored.
Keep an eye on vulnerable people in the household during a longer interruption. Anyone reliant on electrically powered medical equipment should follow their emergency plan and contact the relevant care provider or emergency service where necessary. In cold weather, close internal doors, use blankets and avoid using barbecues, camping stoves or portable fuel heaters indoors. These create serious carbon monoxide and fire risks.
If you run a business, a power loss may also affect alarms, refrigeration, tills, data systems or access controls. Avoid restarting every item at once when the supply returns. Bring essential equipment back online gradually and check for alarms, damaged stock or systems that need resetting.
When to call an emergency electrician
You should arrange urgent electrical help when the issue appears isolated to your property and cannot be resolved by safely checking the consumer unit. A prompt call-out is sensible if you have no power in part or all of the property, a breaker will not stay on, a socket or switch feels hot, lights flicker unexpectedly, or you have found water near electrical equipment.
Landlords should take reports of lost power particularly seriously. Tenants need a safe, usable electrical installation, and recurring faults should be investigated rather than patched over. Keeping records of repairs and arranging Electrical Installation Condition Reports at appropriate intervals helps identify deterioration before it becomes an emergency.
At Gerrard’s Electrical Solutions, fault finding starts with a methodical assessment of the circuit and installation. The work is carried out in line with current BS 7671 requirements, with clear advice on what has failed, what needs repairing and what can wait. A good electrician should explain the options in plain English, provide transparent costs and leave the work area tidy.
Preventing future power problems
Not every outage can be prevented, especially when the wider network is affected. However, regular attention to your own installation reduces the chance of internal faults. Avoid overloading extension leads, replace damaged plugs and leads, keep electrical items away from water and have persistent tripping investigated promptly.
If your consumer unit is old, lacks modern safety protection or has become crowded with later additions, an upgrade may be worth discussing. Likewise, homes with ageing wiring, frequent DIY alterations or major renovation plans can benefit from an Electrical Installation Condition Report. It gives a clear picture of the installation’s condition and highlights any work needed to keep it safe and compliant.
A power outage is disruptive, but it does not need to become a crisis. Stay calm, check whether the fault is local or network-wide, avoid risky DIY fixes and act quickly if there are any signs of electrical danger. A careful response now is often what prevents a small fault from becoming a much bigger problem later.
