Power Cut at Home in Addlestone What to Do Step by Step

Published September 2026 | Power cut at home what to do step by step

A homeowner in Addlestone notices that every light in the house goes out at exactly the same moment - the television cuts off mid-programme, the fridge stops humming, and the whole house falls into an unusual quiet. She looks out of the front window and sees the neighbouring properties are dark too, but she is not sure whether that means a network fault has hit the street or whether something inside her own home has tripped. She has got two young children upstairs, a chest freezer full of food in the utility room, and no idea who to call first. What she does in the next thirty minutes will determine whether this stays a minor inconvenience or turns into something expensive and stressful.

What Was Actually Going On

Power cuts fall into two distinct categories, and getting this right immediately is the most important thing our engineers emphasise. The first type is an external fault - a problem on the distribution network between the substation and your meter - which is the responsibility of your Distribution Network Operator (DNO). For Addlestone and most of Surrey, that DNO is UK Power Networks. The second type is an internal fault - something that has gone wrong on your side of the meter, inside your home - which is entirely your responsibility to investigate and fix.

In this particular case, the cause was a fault on a local underground cable affecting several streets in the Addlestone area. UK Power Networks had it logged within minutes of the outage starting and dispatched a crew the same evening. The homeowner was back on supply in around two and a half hours. But here is the thing - she did not know it was an external fault the moment the lights went out. And making that determination quickly is the entire point of working through the steps below.

Our engineers use the Voltrade GoFIX diagnostic tool to log and categorise electrical faults reported through the platform, and a significant proportion of calls that start as "I've had a power cut" turn out to be internal faults - tripped RCDs, overloaded circuits, or failing appliances pulling too much current. These are not power cuts in the network sense. They look identical to the homeowner, but they need completely different responses.

How the Problem Was Resolved - A Step by Step Guide

Here is the sequence our engineers recommend any time a homeowner in Addlestone loses power unexpectedly. Work through these in order before you call anyone.

Step 1: Stay calm and do not touch anything electrical immediately. If power has just cut out, take thirty seconds to assess the situation. Check whether you can smell burning - if you can, evacuate and call 999. If everything seems normal apart from the loss of power, proceed to the next step.

Step 2: Look out of a window and check neighbouring properties. If the street is dark or surrounding houses have clearly lost power, the fault is almost certainly on the network. If your neighbours still have lights on, the fault is almost certainly internal to your home.

Step 3: Call 105. This is the free national power cut helpline that connects you directly to your DNO. For Addlestone, that routes to UK Power Networks. You can also use the UK Power Networks online power cut checker - enter your postcode and it will tell you whether a fault is registered in your area. If there is a network fault, it will typically show up within minutes of an outage starting. UK Power Networks also offer automated text alerts if you register your address with them in advance, which is well worth doing before you ever need it.

Step 4: Check your consumer unit. This is the grey or white box - usually found in a hallway, under the stairs, or in a kitchen cupboard - that houses your circuit breakers and RCD switches. Open the cover and look at the position of every switch. In a healthy consumer unit, all switches should be pointing upwards in the 'on' position. If one or more have dropped to 'off', or if the main RCD switch has tripped, you have an internal fault rather than a network outage.

Step 5: If the consumer unit looks fine and 105 confirms a network fault, your job is to wait safely. Unplug sensitive electronics - computers, smart televisions, gaming consoles - to protect them from a potential voltage surge when supply is restored. Keep the fridge and freezer closed. A sealed fridge stays cold enough to be safe for around four hours. A well-stocked chest freezer will commonly hold temperature for 24 to 48 hours provided the door stays shut.

Step 6: If the consumer unit shows a tripped breaker or RCD, try resetting it once. Push the switch firmly back to the 'on' position. If it holds, check which room or circuit it covers and identify whether a specific appliance triggered the trip. If it trips again immediately or within a short time of being reset, do not keep resetting it. There is a fault in that circuit and it needs investigating.

Step 7: If you cannot identify the cause and the fault persists, call a qualified electrician. Look for NICEIC or NAPIT registered tradespeople - these are the recognised competent person schemes for electrical work in the UK. Do not attempt to investigate the wiring yourself, and do not bypass the protection mechanism by forcing switches or using tape to hold them in position. The RCD or breaker is doing its job - it is telling you something is wrong.

What This Cost and How Long It Took

For the Addlestone homeowner in our scenario, the network fault cost her nothing directly. UK Power Networks are required to restore supply and they carry all repair costs. Under the Guaranteed Standards of Performance, if your DNO fails to restore power within 12 hours (or 24 hours during a severe weather event), domestic customers are entitled to compensation - typically 75 pounds for the first period, with additional payments if the outage continues.

If the fault had been internal, the costs would have been different. Here is what homeowners can realistically expect to pay for electrical fault work in 2026:

• Electrician callout charge: typically 60 to 120 pounds depending on time of day. Evening and weekend rates are higher.
• Fault-finding investigation: typically 80 to 150 pounds for the first hour, then 50 to 100 pounds per additional hour.
• Replacing a single circuit breaker: typically 80 to 150 pounds including parts and labour.
• Replacing an RCD unit: typically 100 to 200 pounds.
• Full consumer unit replacement: typically 600 to 1,200 pounds depending on the size of the installation and whether any additional work is needed to bring circuits up to current standards.

A routine circuit fault investigation and repair in an Addlestone property generally takes one to three hours from arrival. A full consumer unit replacement is a full day's work - the supply will be off for much of that time, so plan accordingly.

These cost ranges are why it is worth working through the diagnostic steps before calling anyone. If the fault is external, the DNO fixes it at no cost to you. If a single RCD reset resolves it and stays resolved, job done in two minutes. You only need to bring in a professional when the problem is internal, persistent, and cannot be traced to a specific appliance.

How to Spot the Same Issue in Your Home

A sudden total loss of power is the obvious signal, but there are subtler warning signs that your electrical installation is under stress - and catching them early typically means a much smaller repair bill.

Frequent tripping. If a circuit breaker or RCD is tripping more than occasionally, that is not normal wear. Something in that circuit is drawing excessive current or there is an insulation fault developing. Common culprits include older tumble dryers with failing heating elements, ageing dishwashers, and storage heaters whose internal components have degraded. Brands like Hotpoint and Beko tend to have well-documented fault histories on specific models - worth checking the manufacturer's site if tripping correlates with one particular appliance switching on.

Flickering lights. Brief flickers when a large appliance starts up can be within normal range. Persistent or worsening flickering points to a loose connection in the circuit. Loose connections generate heat over time and can become a fire risk if left unattended.

A burning smell near sockets, switches, or the consumer unit. This is an emergency. Turn off at the main switch on your consumer unit and call a qualified electrician before using the affected circuit again.

Scorch marks or discolouration around a socket or switch plate. This indicates arcing has occurred - an electrical fault that has produced enough heat to damage the fitting. The circuit needs to be taken out of service and inspected professionally.

An older consumer unit with ceramic fuse wire rather than circuit breakers. Many properties across Addlestone built or last rewired in the 1970s and 1980s still have these older boards. They do not provide anything like the protection of a modern unit with RCDs and arc fault detection, and some insurers now ask about them specifically when assessing domestic properties. If your board looks like a row of small ceramic plugs rather than plastic switches, get it assessed.

Lessons - What Every Addlestone Homeowner Should Know

Our engineers have been to a lot of call-outs across Addlestone and the broader Surrey area. A few things come up repeatedly.

Know your DNO before you need them. The number 105 connects you to your local DNO from anywhere in the UK, but it is worth knowing that UK Power Networks cover Addlestone specifically. Saving 105 in your phone and registering your address on the UK Power Networks outage alert system takes under five minutes and is practically useful when a fault hits at 11pm on a Sunday.

Your consumer unit is not fit-and-forget equipment. Since 2016, regulations have required consumer units in domestic properties to use non-combustible (metal) enclosures rather than plastic. If yours is an older plastic box, it is not automatically dangerous, but it would not meet current standards if the work were carried out today. This often comes up in EICR reports and property surveys.

Know your compensation rights. If UK Power Networks fails to restore your supply within the Guaranteed Standard timeframe, compensation does not arrive automatically - you need to claim it. Keep a note of when the power went off, when it came back, and the reference number from your call to 105 or the online checker. Claims are typically submitted through the DNO's website.

Prepare before anything happens. Addlestone is served by a mix of underground and overhead cables. Overhead sections are vulnerable to storm damage, particularly through autumn and winter. Keeping a reliable torch, a portable battery pack, and a small supply of candles is basic sensible preparation. Knowing where your consumer unit is and what it looks like before a fault occurs saves valuable time when one does.

Do not treat a tripped RCD as a minor nuisance to reset and ignore. Our engineers have attended properties in Addlestone where homeowners had been resetting a tripping RCD for weeks. In several of those cases there was genuine damage to wiring or a failing appliance that would have become dangerous if left much longer. One trip might be a one-off. Two trips from the same circuit in a short period needs investigating.

Consider an Electrical Installation Condition Report if your property is overdue. This is a professional inspection of all fixed wiring in the home, carried out by a qualified electrician and valid for up to ten years on most domestic properties. Landlords in England are legally required to hold a valid EICR every five years. For owner-occupiers it is not a legal requirement, but it is the only way to know the condition of wiring hidden behind walls and ceilings. If the property was last checked more than a decade ago, it is worth arranging one.

Related Questions

Who is responsible for fixing a power cut in Addlestone?

If the fault is on the distribution network - the cables and equipment between the local substation and your electricity meter - that is UK Power Networks' responsibility. They cover all repair costs and must restore supply within set timeframes. If the fault is on your side of the meter, inside your home, that is your responsibility and you will need a qualified electrician to diagnose and fix it. Calling 105 or checking the UK Power Networks outage map for your postcode is the fastest way to determine which situation you are dealing with.

How long does a typical power cut last in Surrey?

Most cable or equipment faults on the UK Power Networks network in Surrey are resolved within one to four hours for a single localised fault. Storm-related damage affecting overhead lines can take considerably longer, particularly if multiple faults need repairing across a wide area. Under the Guaranteed Standards of Performance, DNOs must restore supply within 12 hours for most domestic customers during normal conditions, or 24 hours during a severe weather event. If those targets are missed, compensation is available - but you must claim it rather than wait for it to be paid automatically.

Can I reset my own consumer unit after a trip?

You can reset a tripped circuit breaker or RCD yourself - push the switch firmly back to the 'on' position. If it holds, identify which circuit it covers and check whether a specific appliance caused the trip - unplug appliances on that circuit one by one and see if the breaker stays on. If the switch trips again immediately after you reset it, stop resetting it. A persistent trip points to a wiring fault or failing appliance that needs a qualified electrician to investigate. Resetting repeatedly without finding the cause can allow a dangerous fault to continue undetected.

What should I do about food in the fridge and freezer during a power cut?

Keep both doors closed as much as possible throughout the outage. A sealed fridge will commonly hold a safe temperature for around four hours without power. A full chest freezer, kept closed, will typically maintain a safe temperature for 24 to 48 hours. Once power is restored, check food before consuming it - anything that has fully thawed and been sitting at room temperature for more than two hours should be discarded rather than refrozen. When in doubt, throw it out; food poisoning is not worth the saving.
