Power Failure

Call 105 if you are experiencing a power cut.


Many of our daily activities rely on electricity, therefore a power failure can cause disruption.
The majority of the time a power outage will be rectified in a matter of minutes, however, there is a small possibility of it lasting much longer.
In the event of the latter, you will find yourself without many of the basic amenities you rely on, such as central heating or running water.
Power outages will often occur with little or no warning, therefore it is important to take steps beforehand to be prepared.

Step 1 - Stay Aware of the Situation

Staying informed in a power cut offers a challenge. However, you could:

Step 2 - Be Prepared

  • Consider purchasing an old-style plug-in phone which doesn’t rely on an electricity supply
  • Consider purchasing a heating source that doesn’t rely on electricity
  • Keep bottled water in case your water supply is disrupted
  • Keep a torch in an easily accessible location
  • In the event of a power cut:
    • Turn off all appliances to avoid damage from power surges
    • Check with neighbours to ensure the power outage isn’t contained to only your home. If it is common to several properties, notify your local electrical supplier if possible
    • Try to avoid opening your fridge/freezer. A closed freezer may keep food frozen for up to 24 hours if left unopened
    • Candles are not advised due to fire risk - seek out safer battery-powered alternatives
  • If a power outage is expected to last for an extended period, you may be required to evacuate your home. Prepare a grab bag in advance for use in the event of an evacuation
  • Check on vulnerable neighbours and make sure they are okay and have sufficient supplies/resources to cope
