Electrical and heating appliance safety advice

Advice on staying warm and safe in your home.

1 Electrical safety

Learn how to ensure that your heating appliances and electrical equipment don't put you and your family at risk from fire by following these simple steps.

Avoiding electrical fires

  • Never leave electrical items plugged in or unattended, especially at night.
  • Regularly check that flexible cables on all electrical appliances are not worn or coming out of the plug.
  • Make sure you have a working smoke alarm.

Plug safety

It’s a good idea to check plugs and plug wires regularly. Plugs and their cables can be damaged with use.

  • Check the plug meets British Standard BS 1363 - it will be marked on the back.
  • Look for cracks or damage on the casing.
  • Look for signs of overheating, such as discoloured casing or cables, or scorch marks around a socket or plug or on an appliance.
  • Be aware if there is a smell of hot plastic or burning near an appliance or socket.
  • Check appliances if fuses blow or circuit-breakers trip for no obvious reason.

Overloading sockets

  • Never overload an extension lead by plugging in too many appliances. This could cause the plug on the wall socket to overheat and start a fire.
  • Only use one socket extension lead per socket and never plug one extension lead into another.
  • Use the socket calculator to check you aren't overloading your sockets.
Check to see whether you are overloading your sockets. (external link)
