Understanding power cuts: roles and causes

When a power cut occurs, it's natural to feel anxious and unsure who to contact. Understanding the difference between your energy supplier and the network operator is key to getting the right help quickly.

What causes a power cut?

Power cuts, also known as power outages, can be caused by a variety of factors. These range from severe weather damaging overhead lines to underground cable faults or even planned maintenance work by network operators. These interruptions to your electricity supply are usually unexpected, but knowing the correct procedures can minimise disruption.

Your energy supplier vs network operator

It's crucial to understand that electricity power cuts are managed by Distribution Network Operators (DNOs), not energy suppliers like Fuse Energy. Your DNO is responsible for the physical electricity network in your area, including the cables, pylons, and substations that deliver power to your home. They are also responsible for restoring power during an outage. Fuse Energy, as your energy supplier, handles your billing, account management, and customer service for your gas and electricity supply.

How to check for a power cut

If your power goes out, first check if your neighbours are also affected. This can help determine if it's a localised issue or a problem within your property, such as a tripped Fuse. If your neighbours also have no power, it's likely a power cut affecting the wider area.

You can find your local Distribution Network Operator (DNO) using the Energy Networks Association postcode tool. This tool will direct you to the correct DNO for your region, who can provide updates on the power cut status.

Preparing for a power cut: your essential checklist

Being prepared for a power cut can significantly reduce stress and disruption. A well-stocked emergency kit and a clear plan are your best defence.

Emergency kit essentials

An emergency kit should contain items that will help you manage without electricity for several hours. Consider including:

  • Torches and spare batteries: Far safer than candles.
  • Portable chargers or power banks: Keep your mobile phone and other essential devices charged.
  • Battery-powered radio: For news and updates.
  • First-aid kit: For minor injuries.
  • Bottled water: Ensure you have enough for drinking and basic hygiene.
  • Non-perishable food: Items that do not require cooking or refrigeration.
  • Warm blankets and extra layers: To stay warm if heating is affected.

Charging devices and backup power

Before a predicted power cut or as part of your general preparedness, ensure all mobile phones, laptops, and portable chargers are fully charged. Consider investing in a larger power bank or a small generator if you have critical medical equipment that relies on electricity.

Food and water storage

Keep a supply of non-perishable food items that do not need cooking, such as tinned goods, biscuits, and dried fruit. Store bottled water for drinking and basic washing. If a power cut occurs, avoid opening your fridge and freezer frequently to help keep food cold for longer. A typical power cut lasts for a few hours, but durations can vary significantly depending on the cause and complexity of the fault.

During a power cut: safety and management

Safety is paramount during a power cut. Knowing how to manage your home and report the outage correctly will help keep you and your household safe.

Prioritising your safety

  • Electrical safety: Turn off and unplug non-essential appliances to prevent damage from power surges when electricity is restored. Leave one light on so you know when the power is back.
  • Carbon monoxide awareness: If you are using alternative heating or cooking methods, such as gas heaters or camping stoves, ensure they are used in a well-ventilated area to prevent carbon monoxide build-up. Never use barbecues or outdoor heaters indoors.
  • Medical equipment: If you rely on electrically powered medical equipment, inform your DNO in advance by registering for the Priority Services Register (PSR).

Managing food and heating

As mentioned, keep fridge and freezer doors closed as much as possible to preserve food. A full freezer can keep food frozen for about 48 hours, while a half-full one will last about 24 hours. For heating, dress in layers and use blankets. If you have a gas hob, you might be able to use it for simple cooking, but be mindful of ventilation.

Reporting a power cut

The national power cut helpline number for all of Great Britain is 105. This free service connects you directly to your local DNO, allowing you to report an outage or get updates on existing ones. Do not contact Fuse Energy for immediate power cut reporting, as your DNO is the responsible party.

Who should I call if my power goes out?

If your power goes out, you should call 105, the national power cut helpline for Great Britain. This free service connects you directly to your local DNO, who is responsible for restoring your electricity supply.

After the power cut: recovery and support

Once power is restored, take a few steps to ensure your home is safe and to understand any potential next steps.

Safely restoring power

When the power comes back on, switch on your appliances gradually to avoid overwhelming the system. Check your circuit breakers if any individual circuits remain off. Understanding your home's electrical setup, perhaps through a recent smart meter installation, can be helpful here. If you notice any flickering lights or unusual smells, contact your DNO immediately.

Checking for damage

Inspect your home for any damage caused by the power cut, particularly to sensitive electronics. If any appliances appear to be damaged, do not use them until they have been checked by a qualified electrician.

Understanding power cut compensation

DNOs operate under Guaranteed Standards of Performance. If these standards are not met, compensation may be due. Fuse Energy does not manage power cut compensation; any claims would be handled directly by your DNO.

Extra support: the Priority Services Register

The PSR is a free support service designed to help vulnerable customers during power cuts and other energy-related issues. Both your energy supplier and your network operator keep one.

Who is eligible for the PSR?

You may be eligible for the PSR if you or someone in your household:

  • Is of State Pension age.
  • Is pregnant or has young children (aged 5 or under).
  • Has a disability or a long-term health condition, including mental health conditions.
  • Has impaired sight, hearing, or sense of smell.
  • Relies on medical equipment that uses electricity.
  • Is recovering from an injury or a recent hospital stay.
  • Has recently experienced a bereavement or job loss.
  • Needs extra assistance during power cuts or supply interruptions for any other reason.

These categories are indicative; if you feel you need extra support, you should register.

How to register for the PSR

You can register for the PSR through your energy supplier or directly with your DNO. To register, you will typically need to provide:

  • A secondary phone number (optional).
  • An alternative contact's name and phone number (optional).
  • The alternative contact's full address (optional).
  • The reason for being added to the PSR (e.g., reliance on medical equipment).

Support from Fuse Energy

Fuse Energy can facilitate PSR registration for its customers. This ensures that if you are eligible, you receive the extra support you need during outages, aligning with our commitment to provide comprehensive assistance.
