Before the lights go out

Torches or LED lamps and spare batteries in every room, instead of candles.
A battery or hand-crank radio to follow official announcements.
Charged power banks. When a warning is issued, fully charge your phone.
Cash in small and large notes, because cards and cash machines may not work.
Water: 2–3 litres per person per day (drinking plus cooking and washing), for at least 3 days.
Food you can eat cold, and a camping stove for use outdoors.
Warm blankets, sleeping bags and clothes.
A battery carbon monoxide alarm if you have a stove, fireplace or gas heating.
Agree a meeting point with your family and write important numbers on paper.

When the power is out

Check your fuse box and whether your neighbours have power.
Unplug electronics and leave one lamp switched on so you know when power returns.
Keep the fridge and freezer closed.
Gather everyone in one room, the warmest one, and keep the door shut.
Listen to the radio for announcements and save your phone battery.
Check on older and lonely neighbours.

Special needs

Does someone rely on powered medical equipment? Agree an emergency plan and backup power with their doctor or equipment supplier.
Have medicines that must stay cold, such as insulin? Ask a pharmacist how to store them without power.

Watch out

Never use a grill, camping stove or generator inside your home or garage. It can cause carbon monoxide poisoning.
Connect a generator only as its manual says, and never plug it directly into a wall socket.

Frequently asked questions

How do I prepare for a blackout?

How much water do I need for a blackout?

Official guides recommend 2–3 litres per person per day, for at least 3 days. In blocks of flats, water pumps may stop working without power.

Torches and LED lamps are safer. Candles are a common cause of fires during outages.
