What to do in an electrical emergency

What if you have a power cut?

In the event of a power cut please contact your local network operator.

Checking your trip switch

Modern electric circuits are fitted with a circuit breaker fuse system. If a fault develops, a switch is tripped. If you have a trip switch, it will be on or near your fusebox. Your fusebox will always be near to your electricity meter. Your trip switch should have a “push to test” or a “reset” button.

Switches can trip for a number of reasons:

  • An overloaded circuit – too many electrical appliances used at once
  • A faulty appliance

  • Over filled kettle
  • Faulty connections on appliance leads

  • Faulty immersion heater

If a switch has tripped because of one of these reasons, you should flick it back on and then re-plug these items in one by one. If the switch trips again, you will know that particular item is faulty.

This is a problem within your premises, so do not call your supplier. You will need to call a qualified electrician to come out and fix the problem.

If the switch is on and the “push to test” button doesn’t trip the switch, this means that there is no incoming electricity supply so you will need to call your local network operator's emergency line.

Power cuts

If the local network operator is aware of a loss of power in the area and is dealing with it, then you may receive a recorded message when calling, giving you the relevant information. If you have any particular information about why the loss of power occurred you should let them know so the supply can be restored as soon as possible.

If there is a planned interruption to your electricity supply you should have been previously informed by your supplier.
