Power cut safety
- Fallen power lines
Keep well back (at least 10 metres / 33 ft is a common guide) from fallen wires and anything touching them – treat them as live. Call 105, or 999 if there is danger to life.
- Generators and barbecues outside only
Run petrol or diesel generators well away from doors and windows – never indoors or in a garage. Never bring a barbecue or camping stove indoors. Carbon monoxide is invisible and deadly.
- Carbon monoxide alarms
Fit a battery-powered carbon monoxide alarm. If it sounds, get outside into fresh air and call 999. For a suspected gas leak call 0800 111 999.
- Food safety
Keep fridge and freezer doors closed: an unopened fridge keeps food cold for about 4 hours, a full freezer for about 48 hours (24 hours if half full). The fridge should stay below 8 °C.
- Use a torch, not candles
Keep a torch and spare batteries to hand. Candles are a fire risk – if you must use one, put it in a stable holder and never leave it unattended.
- Unplug electronics
Unplug sensitive appliances to avoid damage from surges when power returns. Leave one light switched on so you know.
- Heat & cold
Wear layers and close off unused rooms. For non-emergency health advice call NHS 111; call 999 in an emergency. Check on elderly or vulnerable neighbours.
- Medical devices and extra support
If you rely on powered medical equipment, join your network operator’s free Priority Services Register and keep a backup plan.
- Dark traffic lights
Treat junctions with dark signals with great caution, as if the lights were not there.
