How to check whether there is a power cut in your area

Before you ring anyone, the quickest test is the neighbour check. If your neighbours and the street lights still have power, the fault is probably inside your home rather than on the network, and the likely causes are a tripped fuse, a tripped trip switch or a prepayment meter that has run out of credit⁵. If the whole street is dark, it is a network fault and the operator needs to know.

Is it a power cut or just your home? The neighbour check

The distinction matters because it decides who you contact and how quickly the fault is fixed. A fault on the network is the operator's responsibility; a fault inside your property is yours, your supplier's or an electrician's.

Work through the checks in order. If you have a prepayment energy meter, confirm you are still in credit. Look at the fuse box for a tripped fuse or switch. Then look outside: if neighbours' lights are on and street lights are working, the problem is likely to be your main fuse or an internal fault rather than a wider outage⁵. The Met Office puts the same point plainly: if your neighbours still have power but your home does not, it is likely there is a problem with the fuses or trip switches in your home¹⁰.

A smart meter does not change this. A smart meter cannot cut off your power, and it does not restore it either; it measures and reports consumption¹¹. If the meter itself appears faulty, that is a supplier matter rather than a network one¹².

If the fault is yours, contact your energy supplier about a faulty meter, or an electrician about the wiring. If it is the network, the next section applies.

Dial 105: the free power cut helpline

The 105 number is the single national route for power cuts in Great Britain. It is free to call from a mobile or a landline, it links you to your local operator's emergency number, and it is available 24 hours a day¹. Network operators, gas distributors and consumer bodies all promote the same number, which is a useful sign of how settled it is: "Have a power cut? Call 105" appears across operator and gas distributor guidance alike¹³.

What 105 does is route, not repair. It connects you to the distribution network operator for your area, the company in charge of the supply to your area, which is also the body to contact about power cuts or connection issues¹⁶. That operator holds the fault map, the restoration estimates and the record of who is off supply.

The number is also the reporting route for specific hazards. Electricity North West asks households to call 105 or report a power cut online after flooding so it can carry out a safety check²⁰. Care and assisted living providers are directed to the same free emergency number when their residents lose supply²¹.

For a household, 105 is the lowest-friction option available: no app, no account, no broadband. It works on any phone with signal, which is exactly the condition a power cut creates.

Power cut checkers by network: Northern Ireland Electricity Networks and your local operator

Every distribution network operator runs its own outage map or checker, and these are the fastest way to see whether a cut is already known and when supply is expected back. NIE Networks offers a tool to check if there is a power cut in your area, and customers can report having no electricity online³. When a planned emergency power cut starts, the rota for power cuts is published on the NIE Networks website⁷.

Northern Ireland sits outside the 105 system. The contacts are:

If your power is not restored within an hour of the scheduled time, NIE Networks directs customers to its Power Check tool for more information and to report the power cut again⁷. That one-hour rule is worth remembering: a missed restoration time is itself a reason to make contact.

Complaints follow the same split. For complaints about power cuts or connection problems, contact your distribution network operator, the company in charge of the supply to your area²². Complaints about billing, payments or the account itself go to the supplier instead²³. Age UK draws the same line for older consumers²⁵.

What to do while the outage continues

Once the cut is reported, the practical work is keeping warm, informed and contactable. Network operators recommend keeping a mobile phone fully charged so it can be used to go online for updates or to call, keeping a torch handy, and having warm clothes, blankets and food that does not need heating accessible²⁶. SSEN's list adds a battery-powered radio tuned to a local station, a note of key contacts, checking with neighbours, a thermos flask for warmth, and saving work regularly².

Support during a long outage is not limited to information. Electricity North West states that it will keep customers updated throughout the power cut, and for customers with poor mobility during extended power cuts it can provide hot food and drinks or, where appropriate, overnight accommodation²⁸. NIE Networks contacts customers on its Customer Care Register regularly during a power cut with up-to-date information³⁰.

For a household thinking about independence, the pattern is consistent: information and support depend on a phone with charge and a signal, and heat depends on electricity even where gas is still flowing. That is the dependence a backup power plan is designed to reduce, whether through a portable power station for phones and lighting or a larger system for heating circuits.

How long a cut lasts, and what compensation may follow

Routine faults are usually restored within hours, but the published durations in the guidance cover planned emergency disconnections rather than everyday faults. Under a rota load disconnection, customers would lose power for around three hours per day during the emergency, on an area-by-area basis⁸. Block letters are timetabled to be without power for typically around three hours once or twice a day⁷. The mechanics of that system are set out in rota power cuts.

Compensation is a separate question from restoration. Ofgem's guaranteed standards scheme sets payments for qualifying outages, but it excludes blackouts caused by a national power shortage, damage to electrical equipment or appliances, and a low supply after a power cut³². The qualifying thresholds and amounts are covered in power cut compensation, with the Northern Ireland position in power cut compensation in Northern Ireland.
