What to do in a power cut and who to contact



This guide is intended to provide general guidance only. It is not intended to give you advice on your personal financial circumstances. You should seek independent professional advice if you’re unsure about anything mentioned in this guide or what choices to make.

So you’re cosied up in the lounge, watching TV or listening to the radio, maybe surfing the net at the same time. Dinner’s in the oven and you’re thinking about putting a DVD on. Then suddenly there’s a ‘click’, and your world is plunged into darkness. Uh oh, it’s a power cut. Do you know what to do in a power cut?

First things first

Have a peek out the window. Can you see if your neighbours’ lights are on? If they’re not (or if the streetlights are out too, although they’re not always affected by power cuts), then it’s likely there’s a power shortage in the area. In this case, you need to ring your electricity supplier to inform them of the problem (it’s helpful to have the right number written down somewhere in case of such an event), and they should be able to tell you what’s going on.

If your neighbours’ lights are still twinkling away then the issue might be with your fuse box, so check it to see if any trip switches have gone off. If not, then the problem might be more complex and you should call an electrician.

Switch off appliances

Things like irons, ovens, electric fires and fryers need to be turned off straight away, because they could pose a hazard if the power comes back on and they’re unattended while you’re in bed or if you go out.

Fridges and freezers

Fridges and freezers will keep food cool for several hours after the power goes out, so don’t panic! If you have ice in your freezer, put it in a cool box along with refrigerated dairy items such as milk, cheese, fish and meat to keep it fresh. Freezers will keep food frozen for longer if they’re fuller, so consider filling any gaps with tubs of water. Avoid unnecessarily opening fridge and freezer doors if possible, and cover freezer chests with blankets to create extra insulation (remember to take them off once the power is back).


It’s much safer to use torches than it is to burn candles or paraffin lamps, but if you must use these items then make sure you use them safely:


It’ll take a little while for your house to cool down if you’ve had the heating on, but if you find yourself getting chilly, load up on blankets and jumpers – and remember, a hug is a great way to keep warm! Try to keep mobile if possible as physical activity can help raise your body temperature – this is especially important for elderly people.


Most alarms have a battery back-up supply so their operation shouldn’t be affected by a power cut, and electrical locking systems are usually programmed to unlock if there’s an electricity supply problem. However, once the power comes back on you should still check they’re working as they should.

Tropical fish

If the power is off for more than two or three hours, you might start worrying about your fishy friends heat pumps and filters won’t work during an outage. But there are a few things you can do to keep fish happy:

Love thy neighbour

If you live near elderly or particularly vulnerable people, take a few minutes to pop round to check they’re okay and to ask if you can help with anything. The simple act of lending a blanket or helping them up the stairs in the dark could make a lot of difference to them.

Make the most of your down time

Let’s be honest; it’s not often we’re cut off from the everyday distractions of TV, the internet, video games and so on. So why not make the power cut into a fun family event? Tell stories, go outside and look at the stars, hoover through any icecream you’ve got in the freezer – make the most of it! You could even play light switch roulette. Make sure all the light switches are set to ‘off’, then take turns giving them a flick at random intervals. Whoever ends up turning a light on wins!
