What should I do during a power cut?

  • Switch off all electrical appliances that shouldn’t be left unattended, ready for when the power comes back on.
  • Leave a light on so you know when the power outage has been resolved.
  • Check to see if your neighbours are okay.
  • Wrap up warm.
  • Contact your network operator to report the power cut, either by calling 105 or via their other available channels.

What should I do if I see a damaged overhead Electricity line or substation?

Call 105 immediately to report the problem to your network operator. Keep as far away from the hazard as possible. If there is a serious immediate risk (e.g. cables obstructing a public highway), call the emergency services too.

How can I prepare for a power cut?

  • Keep a torch handy – it’s much safer than using candles.
  • Get a battery-powered or wind-up radio (useful for keeping up to date with relevant local news).
  • Keep warm – keep a blanket and warm clothing handy, and fill a vacuum flask or hot water bottle.
  • Stock your cupboard with food and drink that doesn’t require electricity to prepare it.
  • Keep your mobile phone and laptop fully charged.
  • Check your network operator’s website or social media channels for updates.

Can I use my phone during a power cut?

Cordless phones probably won’t work during a power cut. They take their power from the mains and most don’t have battery back-up. Traditional corded phones will work – you might want to keep one handy so you can plug it in and make phone calls if you have a power outage.

In most cases, mobile phones will work if they are charged. If you have a smartphone, you can visit your local network operator’s website or social media channels, where available, to report a power cut and get updates.

I’m on the priority services register. Should I now call 105?

The Priority Services Register is for people who might need extra support during a power cut; for example, people who need electricity for vital medical equipment.

If you are on the Register and you have a power cut, you should continue to call the phone number that you have been given.
