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.
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.
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.
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.
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 sensitive appliances to avoid damage from surges when power returns. Leave one light switched on so you know.
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.
If you rely on powered medical equipment, join your network operator’s free Priority Services Register and keep a backup plan.
Treat junctions with dark signals with great caution, as if the lights were not there.
