How to keep safe during a power cut

  • Make sure your mobile phone is charged just in case you need to make an emergency call.

  • Switch off all electrical appliances, so if power comes back on and you're out, everything is safe.

  • Look out for your neighbours. They may not be as prepared as you.

  • Make sure you have torches and extra batteries.

  • Leave a light on so you know when the power is back on.

  • Wrap up. If it's cold, wrap up warm and close internal doors to keep the heat in.

What is energy theft?

Energy theft is when somebody tampers with a gas meter, electricity meter or their connections so that it does not properly record the energy used.

Energy theft is illegal and can be very dangerous

  • A tampered electricity meter can cause short circuiting, fires and potentially fatal electric shock
  • A tampered gas meter can result in leaks, gas explosions and presents a risk to you and those around you
